Benzoyl Peroxide
| Best used: AM Or PM | Caution: Sensitive skin, rosacea | Best for: Acne |
| Comments: Best antibacterial compound around | Mode of action: Oxidation of bacterial in pimples | Science Score: ***** |
What is the skin science behind benzoyl peroxide?
Benzoyl peroxide is used to treat acne. It works as an antiseptic to reduce the number of bacteria that cause acne. It comes as a gel or face wash, gel, cream, or spot treatment. The most common formulations contain 2.5 to 10% benzoyl peroxide. This powerful anti-acne medication is available over the counter.
Is benzoyl peroxide good for acne?
Benzoyl peroxide is an antimicrobial, meaning it helps reduce the amount of acne-causing bacteria on the skin. This leads to less zits, pimples, & pustules.
Benzoyl peroxide also helps keep the pores clear from blockages & is one of the most commonly prescribed ingredients by skin care experts. Formulations such as Epiduo contain both benzoyl peroxide and retinol to provide a better long term solution for acne patients.
What other acne treatments are there if BPO doesn’t clear my acne?
There are many different ways to clear up your acne including diet, BHA washes, AHA, BHA, retinol peels, lasers & LEDs. Dermatologists also employ anti-inflammatory medications, topicals & vitamin A derived prescriptions. The ideal treatment depends on your type of acne, lifestyle as well as goals & expectations.
* Disclaimer: I am a procedural dermatologist, I do not treat acne, nor do I prescribe acne medications. Please discuss any acne issues with your doctor or dermatologist.
How do I use benzoyl peroxide?
The most common formulation of benzoyl peroxide is a wash. A good starting concentration ranges from 2.5 to 5%. Select a lower concentration if you have sensitive or irritated skin.
Wet the area you want to treat.
Place a small amount of BPO onto your hands.
Smooth it onto the affected areas including acne prone areas
Keep the wash on your skin for no more than 90 seconds.
Rinse your face thoroughly with water (double wash is fine)
Gently pat dry.
Moisturise within 90 minutes if you suffer dry or irritated skin.
Use once a day. If you have sensitive skin, start every second day
The MOST important factor is the ‘contact time’ of BPO; for the product to work you must leave it on for 60 to 90 seconds before washing off.
Benzoyl peroxide also comes in a gel, cream or spot treatment. Be guided by the product information guide; this will vary with manufacturers.

Should I use benzoyl peroxide in the morning or at night?
If you’re new to benzoyl peroxide, start with once every second day. Gradually work your way up to morning or night applications. If you use a retinoid or retinol product at night, apply benzoyl peroxide only in the mornings. This will prevent irritation and other side effects.
Is benzoyl peroxide or salicylic acid better?
Salicylic acid is more effective for blackheads and whiteheads as it acts as a chemical exfoliant. Benzoyl peroxide works on the other hand is best for zits, pimples & pustules. Both ingredients are intended for mild acne breakouts.
Though retinol & retinoids can be useful for pigmentation, there are FAR better options, namely HQ, ascorbic acid, kojic acid, arbutin, #azelaic acid, & botanicals such as licorice root extract & bearberry extract. There’s a lot of marketing behind vitamin A, especially #retinol & pigmentation.
.
👉The Problem: retinoids can reduce your skin’s threshold for irritation, meaning in some cases an irritant dermatitis can prevent the patient from using more effective pigment inhibitors, hence I am not a fan of the widely prescribed triple therapy. I prefer to titrate over time & introduce retinoids gradually, especially during the rotational phases
.
👉📝How to start? Gradually. One night per week (especially if you are using other topicals which may irritate your skin), increase application of retinoid/retinol by one night per week, obviously titrating as tolerated
.
💯👌🏻Practical tips: get your sunscreen application right before even thinking about products/brands. The rate limiting factor is photoprotection, not OTC products

Green tea & the fuzzy bits of skin care 🍵
.
👉Anti Aging: Protection against UV damage: Green tea contains antioxidants & free radical scavengers, protecting your DNA & collagen. In reality you are better off with topicals such as vitamin C & ferulic acid
.
👉Acne: Catechins & polyphenols are antibacterial & anti-inflammatory in nature. Reduces sebum production (oil), adding to antiacne effects & can potentially reduce enlarged pores. Many better ways to treat acne
.
👉Dark circles: Caffeine found in green tea acts as a vasoconstrictor, modulating blood flow under the eyes. You can’t get cheaper eye rejuvenation than using 2 tea bags under your eyes
.
👉Oily skin: Green tea has been shown to reduce sebum or oil production in laboratory conditions. Thus it can be a useful adjunct to medically prescribed retinoids, in theory
.
👉Inflamed Skin; Green Tea can calm down inflamed & angry skin. Inflammatory skin conditions include rosacea, acne, psoriasis & dermatitis. Want some results? Chuck some topical steroid
.
👉Drink tea for the taste & the potential systemic benefits. If you are serious about skincare, there are far better alternatives

Hydroquinone remains as one of the most popular pigment inhibitors. It is still the most effective treatment for pigmentation including melasma, post acne pigment & as a bleaching cream in many Asian & African countries. Hydroquinone was made famous by Michael Jackson, who overdosed on this (as well as propofol).
Concentrations range from 2% to 8% or higher. In Australia this can be purchased over the counter with concentrations of 2% or less. Countries in Asia such as Japan, & many African countries ban the trade & sale of HQ.
Safety concerns are founded by murine studies (rats). Not substantiated. Biggest concerns are, firstly contact dermatitis with higher concentrations, tachyphylaxis (stops working) & exogenous ochronosis (hyperpigmentation instead of fading pigment). Majority of side effects can be mitigated with appropriate use & monitoring. Most dermatologists will limit its use to 3 to 6 months maximum. We rotate other pigment inhibitors such as arbutin, ascorbic acid, licorice root, soy, flavonoids, bearberries, cranberries, & exfoliants such as AHAs.
Accurate titration and application of hydroquinone will reduce side effects and maximise its use.

Here’s how to incorporate retinol into your skin care regime:
The best time to use retinol is in the evening as this molecule is sun sensitive. Start every second night for the first fortnight, & increase as tolerated.
Retinoids can reduce outbreaks of acne, but it can take around 3 months to work.
Step 1: Wash your face with a bland formulation. Do not use skin care acids such as glycolic, lactic or salicylic acids prior to using retinol, as interactions can occur.
Step 2: Wait a few minutes until your skin is completely dry. This is important, because if your skin is still damp, the retinol will be able to absorb more deeply into your skin and might cause irritation.
Step 3: Take a pea-size amount of your retinol and apply with your fingertips in upward and outward motions. If you are unsure how your skin will react, conduct a test patch. This means to try application of a small amount of retinol to the front or the back of your ear.
Step 4: Finish with your moisturizer 30 minutes after application of your ‘actives.’
Step 5: Remember to rise & clean your face in the morning. You should apply a broad-spectrum sunscreen the morning after, as retinol makes skin more sensitive to the sun.
.
👍🏻👀Advanced: DO NOT TRY THIS unless you have an understanding of your skin’s threshold.
.
Who should not use retinol?
People with sensitive skin, including those who suffer from rosacea, dermatitis, or eczema should initiate retinol with absolute caution. For this skin type, consider starting with niacinamide, then retinol as vitamin B is less irritant compared to vitamin A.

🙄 How to choose between alpha hydroxy & beta hydroxy acids! Keep reading & share if you find this post useful 😄
•
🔬Skin science: Alpha-hydroxy acid (AHAs) include #glycolicacid #lacticacid #citricacid #malicacid and #mandelicacid.
AHAs are also known as ‘fruit acids’ 🍊 historically these acids have been in use since the days of the pyramids🗻(True!) AHAs exfoliates the upper layers of skin (epidermis), hence its role in treating unwanted pigmentation. AHA’s also work in the deeper layer of skin, stimulating #collagen, hence its use as a powerful anti aging skincare active.
🧽 Salicylic acid (BHA) is fat soluble and has enhanced penetration into pores and sebaceous glands, hence its use in treating acne and blackheads. BHAs also have anti-inflammatory properties, useful in acne prone skin.
•
✔AHA’s Best For: Chemical exfoliation, skin pigmentation, #melasma, #freckles, #sundamage, photodamage, wrinkles and collagen building.
.
✔BHA’s Best For: #blackheads, #whiteheads, #congestedskin, #acne, #pimples #oilyskin

😎Davs Protip: AHAs and BHAs form the foundation of #cosmeticpeels performed by #dermatologists. For AHA office peels I start at 20%, then 35%, 50% then 70%, whilst for #BHApeels I start at 15%, going up to 30% salicylic acid. Simple preps like Vaseline at the corner of the nose can reduce burns from AHAs. I rate hydroxy acids as one of my top 3 ingredients 👌

Use this cheat sheet to help you navigate the back of bottles! What can be paired together?
It is only a guide as exceptions to the rule applies💯
.
📈📉Think of this as what is represented on a bell curve, those who have sensitive skin will lie at opposite ends of the bell curve compared to those with resilient skin
.
👉An example of resilient skin combinations include #tretinoin or #adapalene & AHAs or BHAs. Skin care acids can increase the absorption of retinoids, amplifying their effects. Conversely they can increase unwanted side effects such as skin irritation, flaking & stinging
.
👉An example of a sensitive skin combination is adapalene with ascorbic acid. For those who lie at the end of the bell curve, this combination can be a problem. Just a topical retinoid alone can give rise to skin irritation. Combining it with a low pH formulation of say 10-20% L-ascorbic acid can markedly increase skin irritation.

.
If you have sensitive skin, it often takes several visits to a dermatologist to understand your skin barrier function & your skin’s threshold. In some cases they may order skin allergy testing to rule out contact dermatitis.
When it comes to Retinol, are you a beginner or ready for more? What is YOUR favourite product?
Comment below👇🏻👇🏻👇🏻
.
.
🔬Skin Science: For first time users or those with sensitive skin, start with a lower concentration of #retinol, or a precursor such as retinyl palmitate. The more steps it takes to convert to retinoic acid, the more gentle on the skin (as a general rule). HPC or hydroxypinacolone retinoate is an exception. This compound can potentially be more powerful than retinol without the side effects of retinoic acid. Understanding YOUR skin’s irritant threshold is super important. The earlier you understand this, the faster you can progress in your skincare journey
.
.
👀📝Brands: There are literally hundreds of brands out there. My take? For more powerful formulations choose a serum. #Skinceuticals make great formulations, medium budget #Obagi, whilst #Murad makes great retinol (Youth Renewal Night Cream) for more sensitive skin
.
.
🎯Precision over Power: Concentrate on precise application over powerful formulations- at least in the beginning. Once you understand how retinoids work & how your skin reacts, THEN explore other options
.
.
🏎Advanced: Yes, combining AHA, BHA & physical exfoliation with retinoids is not a good idea. Advanced uses can ‘prime’ the skin by enhancing the efficacy of actives. DON’T try this if you don’t know your skin’s irritant threshold, nor how to salvage retinoid dermatitis/irritant dermatitis. I will do a video on this in the next 2 weeks

Your skin barrier function is one of the most critical parts of your skin health.
.
.
🔬Skin Science: Your skin is super efficient at keeping out infection as well as irritants & molecules that can predispose to skin allergies. The outermost layer of your skin, known as the stratum corneum is the first line of defence. Skin barrier function can be disrupted in conditions such as atopic dermatitis (eczema), acne, rosacea, as well as self-inflicted causes such as over-exfoliation.
.
👍🏻👀Repair: Simplify to amplify. Stop ALL your skincare products, yes, that includes sunscreen (only for a few days). Halt all your skincare actives, including your #retinol #retinoids, #ascorbic acid, #AHAs, #BHAs & harsh cleansers. In most cases barrier function can be re-established in 2-5 days, longer if you have dermatitis, rosacea or other skin conditions. In some cases a medical #dermatologist can guide you
.
.
🤔🛒Ingredients to help barrier function: Include hyaluronic acid, squalene, ceramides, tocopherol & linoleic acid. The first #skincare active you should use once barrier function is established, is niacinamide
.

What is niacinamide?
.
Niacinamide or vitamin B3 is the go-to skin care active if you have rosacea &/or sensitive skin.
.
This molecule can be combined with most actives. The action of this vitamin can give the following benefits to your skin.
.
- Reduce inflammation & redness (blotchy skin)
- Reduce pigmentation from conditions such as melasma
- Establish barrier function in patients with dermatitis & eczema
- Offers modest immune function regulation from UV damage

✅AHA/BHA: Fence sitting on this one. #enlargedpores; combination can exfoliate the surface (AHA), and penetrate into the oil glands (BHA).
.
.
💯Recommended products: Bang for buck, you can’t go past The Ordinary. Their range of #AHAs and #BHAs provide skincare full of active ingredients at a reasonable price. Rationale AHA is also excellent, whist Neostrata provides great AHA formulations. Neutrogena Oil Free scrub contains salicylic acid. The formulation really comes down to personal preference. .

6 ingredients perfect for hyperpigmentation
.
☀️Firstly, sunscreen use can reduce pigmentation by up to 50%. Get it, use it. Use it properly before spending $$$ on other products
.
🌾Azelaic acid: derived from wheat, great ingredient if you have sensitive skin
.
🍊Ascorbic acid: multi-tasker, pigment inhibitor, anti-oxidant & builds collagen. Caution if you have sensitive skin
.
👀Kojic acid: awesome when combined with arbutin, citric acid, & botanical pigment correctors, caution in high concentrations (contact dermatitis)
.
🌻Arbutin: found in many pigment correctors, naturally good (beta), alpha is lab made, converts to HQ, concentration regulated in most countries
.
🧪Hydroquinone: the big daddy of pigment correctors. For every month of use, give at least 2 weeks break. Example: 3 month use, at least 6 week break. Treat with respect, irritant contact dermatitis, tachyphylaxis (stops working), ochronosis (pigment gets worse
.
👍🏻Niacinamide: anti-inflammatory, pigment corrector, great for sensitive skin. 5-20%, often combined with other key ingredients
.
🎬Action: if you are struggling with pigment, see my nurses at Cutis Dermatology. They are awesome at correcting pigmentation- FAST

What do you think of this order? How do you layer products? Comment below!
.
🔬Skin Science: Why is getting the order correct so important? Firstly penetration of skincare actives. An example is application of water based products over an oil based solution will markedly reduce penetration of the former. Efficacy is hence compromised. On the flipside, applying serums on top of an oil based solution can leave your skin dry & ‘dehydrated’
.
👍🏻Apply thinnest to thickest, light to heavy. Start off with toners, & serums, followed by lotions, creams & then oils
.
💦Water based before oil based
.
📈Lowest pH to highest pH
.
🛒Pick & Choose: Not everyone requires a TONER or an EYE CREAM. If you use a product, make sure it is for a PURPOSE. IMO most people can skip skin eye creams, however if you suffer from say, sensitive eyes, using a paraffin based cream can reduce skin irritation. Conversely if you have #darkcircles due to vascular changes, then a caffeine - argan oil - vitamin K - peptide - hyaluronic acid based eye cream maybe indicated
.
🧴Serums vs creams: Serums have more potential to deliver high concentrations of skin care actives such as #retinol, #ascrobicacid, ferulic acid, vitamin E, & skin care acids. In some cases, serums may not be tolerated on sensitive skin. In this situation using a CREAM Based formulation maybe better

5 No BS tips that every dermatologist will agree upon. Save yourself that consult fee💰
.
🗂Know your skin’s threshold: This is the number one tip. Everyone will have a different threshold, exceed this & your skin will be irritated. By understanding your limits, you will understand what you can, or cannot tolerate. #retinol/#retinoid, & vitamin C- #ascorbicacid are prime examples. Some patients can only tolerate once a week application, others nightly. Think before you buy
.
.
🔎Be precise with your skin care: A skincare regime has a goal, what do you want to achieve? Focus on the goal & work to it. As with a threshold, each active product you apply has the potential of lowering your threshold, this means if you exceed your threshold, subsequent actives may potentially cause skin irritation. Think before you apply
.
.
✔Cleanse: Twice a day only, any more and you may develop irritant dermatitis (then you need to see a dermatologist to fix that up). Let your skin breathe, don’t sleep with make up or you will clog up your #pores. If you have #sensitiveskin, skip the exfoliation, toners & acids
.
.
😛Sugar is not your skin’s friend: Besides it’s gonna make you fat. High glycemic index treats can worsen #acne & #oilyskin
.
.
🌞Sunscreen is never overrated: Cornerstone of #skincare. Invest in a sunscreen that you actually like & use it. Frequently. Don’t skim on the amount. ¾ teaspoon face & neck. Twice a day. Not negotiable. Don’t be SPF tightarse
.
.
💬Bonus tip: Don’t smoke. In Oz a pack of durries will cost ya over 40 bucks. Think how much #botox & #juvederm you can afford if you quit. Re-invest this with procedures that actually work. Health skin, no heart attacks, no stroke, no cancer, can you ask for more?
.
.
😎Davin’s Protip: Your skincare need not be complex, simple works. Be precise, know your goals, know your threshold, don’t be impulsive with your product selection. Buy me a coffee, I just saved you a consult fee

Did you know that acne has certain patterns? There are overlapping patterns, however this face map is pretty accurate
.
👉Hairline acne can be due to products. It can also be due to occlusion & friction, namely acne mechanica
.
👉T Zone acne is common, especially in those with really oily skin, known as seborrhoea
.
👉Cheeks can be involved with all forms of acne, from #maskne through to acne rosacea
.
👉Dots around the mouth & nose area is common with perioral dermatitis
.
👉Jawline acne is suggestive of hormonal imbalance, either endocrine, intracrine or both
.
👉Ears are involved in acne inversa or hidradenitis suppurativa

🔬A dermatologist ‘A’ list to #getshitdone goes something like: Corticosteroids, emollients,( petrolatum, glycerin), tacrolimus, 5 fluorouracil, #retinoids, terbinafine, crude coal tar, LPC /liquor picis carbonis, metronidazole, ivermectin, salicylic, lactic acids and more. You won’t find fluffy niacinamide, caffeine or botanical extracts in our daily prescribing habits. Ginseng, herbs & niacinamide ain’t going to fix your acne or skin inflammation
.
👉Commercial skin care: caters for the joy of self-care, it’s fun. Nothing wrong with aloe vera, tea tree oil & plant extracts- just as long as you don’t get allergic contact dermatitis from it
.
👍🏻Exceptions: Yes, I do prescribe fluffy stuff such as licorice root extracts, arbutin, bearberry extracts, citric acid, retinol & hydroxypinacolone retinoate, but that is mainly during the ‘cycling off phase’ for more potent topical applications. Fluff is still useful in some situations, even if it has a placebo effect💯

This cheat sheet can help you navigate ingredient lists as to what can be paired together, it is only a guide as exceptions to the rule applies💯

📈📉Think of this as what is represented on a bell curve, those who have sensitive skin will lie at opposite ends of the bell curve compared to those with resilient skin
.
👉An example of resilient skin combinations include #tretinoin or #adapalene & AHAs or BHAs. Skin care acids can increase the absorption of retinoids, amplifying their effects. Conversely they can increase unwanted side effects such as skin irritation, flaking & stinging
.
👉An example of a sensitive skin combination is adapalene with ascorbic acid. For those who lie at the end of the bell curve, this combination can be a problem. Just a topical retinoid alone can give rise to skin irritation. Combining it with a low pH formulation of say 10-20% L-ascorbic acid can markedly increase skin irritation.

If you have sensitive skin, it often takes several visits to a dermatologist to understand your skin barrier function & your skin’s threshold. In some cases they may order skin allergy testing to rule out contact dermatitis.
Can I leave benzoyl peroxide overnight?
Benzoyl peroxide washes are ideally a short-term contact therapy that you leave on for a few minutes before washing it off. Gels or creams work better as a leave-on treatment. Be guided by the product information.
Should I use a moisturizer after benzoyl peroxide?
If you’re just beginning with your benzoyl peroxide treatment it is advisable to use a moisturiser 30 to 60 minutes after applying BPO. The trick is to moisturise before you notice any uncomfortable dryness. If you’ve already succumbed to benzoyl peroxide-induced dryness and flakiness, skip anapplicactoin or two & use a moisturizer as often as necessary.
Can I use benzoyl peroxide with retinol?
Advanced users can use both BPO & retinoic acid together. This powerful prescription combination is known as Epiduo. Talk to your dermatologist to see if this medication is suitable for your acne.
* Disclaimer: I am a procedural dermatologist, I do not treat acne, nor do I prescribe acne medications. Please discuss any acne issues with your doctor or dermatologist.
How do I incorporate benzoyl peroxide in my daily skin care routine?
A sensible skin care routine that involves this BPO goes something like this;
AM: BPO wash, SPF, Make up, with the option of antioxidants (Ferulic acid, Tocopherol)
PM: Cleanser, actives such as Niacinamide, Hyaluronic Acid
*The use of retinol, ascorbic acid, BPO, retinoids, & other potentially irritating skin care is NOT an absolute contraindication, you can ease into BPO by listening to your skin, reducing application amount & frequency accordingly. Separate application with a window of 12 hours, use every second day if irritation occurs. Moisturize between applications.
Is benzoyl peroxide an antibiotic?
No, BPO is a powerful oxidizing agent. This chemical kills the cell wall of bacteria implicated in acne (c.acnes). Unlike antibiotics bugs will never develop resistance to BPO, hence why it is such a powerful agent against the zits, pimples, pustules & cystic acne.
What skin care products should not be used benzoyl peroxide?
Retinol with vitamin C, benzoyl peroxide, and AHA/BHA acids. AHA and BHA acids (salicylic acid) are chemical exfoliants, which can dry out skin and cause further irritation. Vitamin C, known as ascorbic acid is often formulated in a low pH base (around 3). This acid may increase skin irritation. Retinol or more accurately retinoids can be formulated with BPO. This prescription gel is known as Epiduo (adapalene or Differin & BPO).
A sensible skin care routine may involve separating BPO from other skin care actives by 12 hours to allow your skin to recover between applications. Be guided by your skin care expert.
Do I leave benzoyl peroxide on my skin?
For BPO washes, leave it on for a minute or two before rinsing it off. Then dry the area gently with a towel and moisturise within 60 minutes of application. Spot treatments can be left on overnight. Instructions will depend on the formulation of BPO. Do not apply it to any areas of skin which are irritated or sore
What percentage of benzoyl peroxide should I use to treat acne?
Research has shown that benzoyl peroxide is just as effective in treating acne at 2.5% and 5% as it is at 10%. The difference is that the higher percentages run the risk of irritating or drying out the skin too much.
If you insist on trying it for your acne, can I suggest using it once a day, mixed into your moisturizer. Test patch a small area before full face application. Good luck.
Will my skin purge with benzoyl peroxide?
Retinoids-retinol, salicylic acids, & benzoyl peroxide are just a few of the products that cause purging. These products contain active ingredients that increase the skin cell turnover rate, therefore causing your skin to purge. Get over the purge (usually 7-12 days) & it should be smooth sailing from there.
How many times a day can I use benzoyl peroxide?
A sensible start routine is to start application once a day or once every 2 days, until your skin gets used to it. Providing your skin is not dry or irritated, you can increase application to once a day. Dry & irritated? Easy, back off, moisturise, then restart! Listen to what your skin is telling you!
Can I apply BPO to a popped pimple?
Pimple popping is fine if you do it correctly. Best executed with a sterile needle to reduce collateral damage to the surrounding skin. After you pop it, apply a thin film of benzoyl peroxide gel (which is available over the counter) to kill the bacteria causing the pimple. Cover with a spot band-aid for a few hours, and you should heal in a few days. Another option is to use ‘acne spot treatments’ or hydrocolloid dressings.
Can benzoyl peroxide remove dark spots?
Benzoyl peroxide can shed dead skin cells as well as bleach your skin, in turn fading dark spots. It may take 1-9 months to see the result, depending on your skin type. Pigment inhibitors such as ascorbic acid, arbutin, niacinamide, licorice, bearberry, flavonoids, & select botanicals do a better job of fading pigmentation. Be guided by your skin care expert.
Does benzoyl peroxide fade acne scars?
BPO is primarily used to treat acne. Once your acne is in remission, your skin’s immune system can regenerate new collagen improving the appearance of mild & early acne scars.
Davin’s Skin Protip on the use of BPO
This still remains as one of the best ingredients for the management of mild to moderate acne. The molecule itself has no bacterial resistance, unlike antibiotics which makes this a good long term solution for acne sufferers. The main side effect of BPO is skin irritation, hence it is super important to have a good, sensible skin care routine. BPO washes can be useful to cover large areas, such as bacne, truncal acne or even butt acne! Remember this is an oxidizing agent, so it can bleach coloured material (pillow cases for example).
