What is the science behind castor oil?
This oil has been used for decades- it’s main use is to treat constipation. Possibly the scientific evidence is equal to the best-known effect of this widely searched oil. Castor oil is derived from the Ricinus plant beans. It is rich in fatty acids including tocopherol (vitamin E). Much like other oils, it has emollient properties & reduces skin dehydration – or more accurately, reduces transepidermal water loss. The occlusive properties of various oils make them a popular treatment for dry hair & split ends.
What are the skin effects of castor oil?
If there was ever an oil that can do just about anything, it is castor oil. It lubricates farm machinery, moves impacted bowels, treats wrinkle, split ends, promotes growth of eyelashes & treats inflamed skin. The reported skin effect of this oil includes-
- Emollient properties: Rich in mono-saturated fatty acids this oil acts as a humectant, reducing water loss in turn functioning as a moisturiser. Castor oil can hydrate skin & hair and reduce split ends.
- Antioxidant properties: High levels of fatty acids & tocopherol (vitamin E), accounts of this oil’s antioxidant properties. Antioxidants protect the skin from free radical damage caused by UV radiation and pollutants.
- Reduces skin inflammation: Ricinoleic acid, the main fatty acid found in castor oil, has impressive anti-inflammatory properties. This oil can reduce inflammation from skin ailments such as psoriasis & eczema.
- Promotes wound healing: Applying castor oil to wounds creates a moist environment that promotes healing and prevents sores from drying out. There are a few case studies on the use of oils for pressure ulcers.
Can castor oil be used to treat wrinkles?
Castor oil contains fatty acids that act as a moisturiser, reducing water loss from the skin. This emollient effect can improve your skin’s texture, reducing fine wrinkles (to be fair, any occlusive moisturizer can do the same). Fatty acids may help in preventing wrinkles as they are shown to have antioxidant properties. There are very limited studies to suggest castor oil can actually increase the production of collagen. Retinol & retinoids do a much better job!

Can castor oil treat acne?
Though the comedogenic potential of this oil is low, most dermatologists would not prescribe this for acne as there are far better treatments with less side effects. If you are into naturopathic essential oil treatments, the oil that has the most research against acne is of course, tea tree oil. Regardless castor oil has been shown to reduce acne by-
- Decreasing skin inflammation as this oil is high in ricinoleic acid, the main fatty acid of castor oil.
- The antimicrobial effect of castor oil can decrease the skin’s population of staphylococcus as well as C.acnes. Coupled with it’s anti-inflammatory effect it may reduce pustules.
Does castor oil treat pigmentation?
No. In theory castor oil can reduce the effects of UV radiation as it has anti-inflammatory properties including antioxidant effects (free radical scavenger as it is high in tocopherol or vitamin E). There are much better skin care products to treat pigmentation & accelerate skin lightening including retinoic, ascorbic, azelaic, & kojic acids. Natural skin lightening can be achieved with arbutin, bearberry, soy, flavonoids & licorice root extracts.
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
.
🐟🛢Diet: some evidence that supplementation with omega fatty acids can help

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

How to choose between alpha hydroxy & beta hydroxy acids, read more & share if you find this post useful
.
.
🔬Skin science: Alpha-hydroxy acids, (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 (Beta Hydroxy Acid) 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, sun damage, photodamage, wrinkles and collagen building.
.
✔BHA’s Best For: blackheads, whiteheads, congested skin, acne, pimples and oily skin
.
✅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. .
⚠️Caution: Sensitive skin warning. If you have rosacea, dermatitis or just angry skin, procede with caution
.
.
😎Davs Protip: AHAs and BHAs form the foundation of cosmetic peels 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.

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
.
🎬Action: Be guided by your dermatologist as to the correct treatments for your acne

Are you a beginner, intermediate or advanced retinol-retinoid user? 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

Don't forget the sunscreen 🌞
Not a complete list, but my most ‘prescribed’ in the context of cosmetics/aesthetic dermatology
.
🔬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💯

.
👉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.
👍🏻Skin Care 101: The first three points on this post are self-explanatory. The fourth requires more thought. If you are going to use skincare products on your face, do it with purpose. Too much & your skin WILL get irritated, your skin barrier compromised & you may get perioral #dermatitis, irritant dermatitis, flare ups of #rosacea, & even allergic contact dermatitis. The last is life long & is real pain in the ar*e to diagnose & manage as allergies are life long🥲
.
👉👀Skin Care 101 Part 2: Choose good formulations of skin care products, not based upon POWER but purpose. Remember, FORMULATIONS matter. As a guide, #retinol for #acne, & antiaging, niacinamide for inflammation, and vitamin C or ascorbic acid for pigmentation. AHAs can be incorporated slowly as a chemical exfoliant
.
📝How to start? : Don’t buy a whole heap of chemicals, start with one at a time, & gradually add over time. If you have sensitive skin, you may require guidance by a skincare professional. Every ingredient should have a purpose in the context of what YOU would like to achieve

❓Why did I choose dermatology over any other career?
.
✅Truth is that I love playing with lasers & quite frankly #blowingshitup🎆, no other career will allow you to actually blow stuff up (legally), except for being an EOD operator (Explosive Ordnance Disposal).💣💣💣 I did that two decades ago as the RMO for the School of Military Engineering.
.
📚Dermatology has many sub- specialities ranging from procedural & laser work, through to equally important work, namely treating disorders of skin, hair & nails. Ideally one should choose the speciality in medicine that suits your interest, that way learning is never a chore.
.
💉To get to the good bit (lasers, fillers, & stuff), dermatologists need to get through the mundane but important bits (histology🔬, immunology,chemistry📖 (allergic contact dermatitis) & physics☢). It is these mundane bits that gives us grounding to interpret the science of skin, enabling derms to largely decipher the true bits from the bullsh*t 💩of skin care marketing and devices.
.
🃏And YES, I am well aware of all the dermatology jokes (best is 'we are nothing more than a finger & an eyeball’), yes we are never really ‘on call’, yes we don’t really cure any skin disorders, yes the idea of a dermatological emergency is essentially treating a pimple before prom night, & yes, it’s a cushy job compared to OBGs and real physicians. The list goes on. Regardless, I love this job, even better than making ANFO, or HMEs with the AFP.
.
For any of my colleagues reading this, chime in your thoughts on being a derm/ derm residency, I really would like to know what you love about this job. (That’s you- Jennifer, Sabrina, William, Phil, Greg, Jason, Belinda, Cara, Leona, Sam, Katie, Heba, sorry if I missed any derms). Tag a derm for me- if you know of any.

Ceramides are naturally occurring compounds that keeps skin hydrated 💧
.
🙄Who should use it: Dry & #sensitiveskin, atopic eczema, Winter #skincare .
.
🔬Skin Science: Ceramides are organic fatty molecules that hold the upper layers of skin. Production of #ceramides decrease with age. Replenishing ceramides can also improve atopic eczema.
By increasing hydration in the upper layers of the skin, actives such as retinol, niacin amide, AHA etc can penetrate to the deeper layers of skin.
Rehydration (to be accurate it is more like reducing transepidermal water loss) can also reduce v v fine wrinkles & improve skin texture.
.
🤷🏻♂️When to apply: AM or PM, before skin actives if you have sensitive skin. Ceramides can help repair barrier function. Great as part of your winter skincare.
.
🥰Plays well with: Everyone. Ceramides can be mixed with your skin care actives.

😎Davin’s Protip: In most individuals the use of ceramides are unnecessary- the exception is when skin barrier is compromised &/or when an individual has a dermatological condition like atopic dermatitis. The subjective ‘feel good factor’ of skincare should not be underestimated, & on this basis, if ceramide releases your oxytocin; by all means knock yourself out!

Rosehip oil is an organic skin care oil derived from the flower species Rosa demascena 🌹 I don’t think any #dermatologist would rush to write a prescription for rosehip, so I would like to know your experience on this oil. Please share & comment🙏🏼

🔬Skin Science: Anti-oxidant, anti-inflammatory & antibacterial.
.
💯 Facts on Rosehip oil
.
🥵Antibacterial & anti-inflammatory properties are potentially the most practical feature of this #essentialoil. High levels of linoleic acid found in oils can reduce irritated skin - especially if you suffer from #acne
.
🍊Rosehip oil is an antioxidant as it contains #flavonoids & vitamin C, #ascorbicacid. Standalone or combination antioxidants such as #ferulicacid, & Vitamin E, combined with C to form Ferulic CE will probably offer better antioxidant properties compared to #rosehipoil .
.
🌤#rosehip has shown to absorb UV & reduce cellular damage. The amount of UV absorption is too low as a reliable SPF. Stick to your #sunscreen for meaningful photoprotection
.
🚦Caution: Contact dermatitis is rare, if in doubt, conduct a patch test. Apply a small amount at the back of your ear. Note that ‘skin allergies’ are most frequently associated with other additives including fragrances, preservatives & parabens. Pure rosehip oil does not react with other #skincare actives
.
😎Davin’s Protip: My product knowledge is limited on the topic of rosehip oil. There are only a few studies on this ingredient. From past clinical experience I do think this oil has a role in the treatment of inflamed acne lesions as it is potentially anti-inflammatory. I’m keen to know your thoughts

What are the hair & eyelash benefits of castor oil?
Castor oil is an affordable, traditional home remedy that has been used for years to treat a variety of conditions, including hair loss. While there haven’t been scientific studies that prove that castor oil can regrow hair, it can benefit dry hair & split ends. Dermatologists will advise the use of better topical solutions for hair growth including minoxidil & bimatoprost for scalp & eyelash hair respectively.
Can castor oil clog pores?
Castor oil has a low comedogenic score which means this oil is unlikely to clog pores. Despite this rating, most dermatologists will err on the side of caution & advise patients with acne prone or congested skin not to use castor oil. If you are persistent on application, conduct a test spot prior to application.
Why is it better to ingest castor oil than to put it on your skin?
The scientific evidence of castor oil for skin is low, however this oil has been used for many decades as a laxative. In today’s age of affordable skin care with solid science, the use of castor oil as a do it all, is less relevant.
What are the side effects of castor oil?
Topical use of castor oil is relative safe, it has a low irritant & allergic potential. The main concern is the comedogenic potential of this oil (even though, in theory this is low). People with congested skin-acne prone skin should be careful. The biggest side effect of castor oil is the reason why this oil is used in millions of households worldwide- it stimulates bowel movement, and hence its use to treat constipation. Topical use will not increase your visits to the toilet as it is not well absorbed.
What does a skin care program involving castor oil look like?
A sensible skin care routine that involving castor oils goes something like this;
AM: Cleanser, SPF, Make up, with the option of antioxidants (Ferulic acid, Ascorbic Acid, Tocopherol, Castor Oil)
PM: Double cleanse, Retinol or Niacinamide – Ascorbic Acid, AHAs or pigment correctors. 5 mls of castor oil for face & neck, 5 mls of castor oil taken orally for bowel movement the next day. Remaining castor oil can be used to lubricate gearboxes, sewing machine, squeaky doors etc…
Davin’s Viewpoint on Castor Oil
I get it, everyone wants a cost effective solution to cure baldness, grow eyelashes, reduce wrinkles, cure inflamed skin, treat split ends, protect against free radicals, stimulate collagen as well as clear your digestive tract of impacted faeces by curing constipation. Sounds good? Try castor oil. For less than 5 cents a day, placebo works. The biggest advantage of castor oil is the last effect of this ingredient- it is great for bowel movement.
I do believe that castor oil is trying very hard to be a jack of all trades, but only mastering the role of a cost-effective traditional laxative. There are over 100 better ingredients one can use on the skin. Criticism aside, any occlusive oil can reduce wrinkles, so that is a plus. Oils can also soothe inflamed skin, so if you run out of moisturizer, then raiding your grandmother’s medicinal cabinet may reveal a bottle of castor oil. Much like the skin benefits, the use of castor oil for hair treatments may have some merit. Oils can ‘moisturise’ dry hair and split ends. In the context of anti-wrinkle treatments, the science of collagen stimulation with castor oil is weak, you are much better off with retinol-retinoids- skin care acids. Nevertheless, castor oil continues to trend upwards in the Google searches for 2023.
