How To Introduce Retinol's/Retinoids Using "The Sandwich Method"

How to introduce Retinoids while minimising the more common side effects.

Anyone who is about to introduce Retinoids into their routine is aware of some of the more common side effects like dryness of skin, peeling, etc. It seems there's a slight misconception that you shouldn't be using retinol at a young age. However, if you're looking to address any of the following issues then a Retinol/Retinoid product may be something to consider as it can assist with: Anti Ageing, Scarring, Uneven Texture, Breakouts, Acne and various forms of Pigmentation. 

These ingredients can be tricky as far as irritation goes as unlike some actives/acids like Vitamin C(L-Ascorbic Acid)/AHA/BHA's where the irritation van be felt relatively immediately. Retinol's/Retinoids can have a delayed effect of up to a few days before you realise "Um I think I've overdone it just a bit". There are ways to avoid or if you have very sensitive skin minimise this. A good option is to use the sandwich method which many dermatologists, aestheticians and other skincare experts recommend. Dr Dray talks about this on YT if you want more info and demonstrations as to how this is exactly done.

The abbreviated version is:
- Layer emollient based product like a thick hydrating serum (a good HA product is ideal for those with true oily acne-prone skin) or lightweight moisturiser (if you're more normal combo or dry) after cleansing and toning (toning is an optional step of course). 
- Allow this to settle so there is no dampness left on the skin.
- Apply your Retinol/Retinoid and allow to sit for a further 5-10mins
- Follow up with another light layer of moisturiser (if you used a serum still follow up with a moisturiser).

A good trick is to apply a balm (something like La Roche Posay's Cicaplast Baume) around the orbital bone area including eyebrows, the mouth and lips and sides of nostrils. These areas you should try to avoid when applying your Retinol/Retinoid as the product will migrate anyway so it's better to buffer the sections you don't want to get the product in.

It's always good to introduce any active slowly. Start once a week in the evening using this method. Depending on the issue your targeting it can vary how much you need and which product to use. Retinol's are good for superficial issues like anti-ageing, minor texture and pigmentation issues. If it's something that goes a bit deeper into the layers of the skin you may see more dramatic results with a Retinoid (like Tretinoin). 

For general anti-ageing purposes 1-3 times is sufficient in addition to an existing routine that contains an SPF.

For scarring and uneven texture b between 3-5 weeks would be the aim there until improvement occurs then reduce frequency. Some products for this is Paula's choice Skin Recover Antioxidant Concentrate Serum with Retinol or The Ordinary's Granactive Emulsion.

If treating something like PIH or Melasma the goal would be between 3-5 nights for PIH and potentially 5-7 nights for Melasma (for the initial period until this had been reduced then the frequency of use would also be reduced).  For these types of conditions, you may see more effective results from a prescription Retinoid. 

With this active the goal is to treat the issue and reduce use or even take breaks where possible, the reintroduce to maintain results achieved. Hope this helps some introducing this ingredient into your routine.

Product Review: Paula's Choice Peptide Booster VS The Ordinary's The Buffet Serum

Today the battle of the Peptides serums is here. Before starting I would like to clarify that this is The Ordinary's The Buffet Serum that does not contain the Copper Peptides (I'm still skeptical of these). I've tested each product for 3 months to get an accurate gauge of the results. A 3 month period is usually a sufficient time to gauge improvements from any active ingredient. Though if it's more deeply seeded issues like acne or hyper-pigmentation this can take additional time. The Ordinary's The Buffet Serum: A fantastic product. This adds moisture to the skin and also gives it a slightly powerless appearance. Paula's Choice Peptide Booster: usually I'm an advocate for Paula's Choice products however, I couldn't get behind this one. It pilled on numerous occasions with various products I tested. A few occasions I was able to get this on without pilling it didn't give that slightly powerless effect The Buffet seemed to provide. ...

Alcohol In Skincare & Cosmetics - What Do They Do, Are They All Bad, What Do I Look Out For?

Let’s talk Alcohol in skincare! Contrary to popular belief alcohol isn’t the worst ingredient around. The more common stripping Alcohols like ethanol, isopropyl alcohol, alcohol denat, and methanol are used to make products more cosmetically elegant, help other ingredients to penetrate, and as a preservative. These types of alcohols when used in high concentrations in skin care can damage your skin’s protective barrier which results in your skin is less effective at keeping moisture in (also known as trans-epidermal water loss). By over stripping the skin it’s natural response is to stimulate oil production which could lead to congestion/breakouts if your skin makes an excess the skin can’t cope with. Some of these alcohols do serve to help with certain  products absorb, or make them more cosmetically elegant. I've always believed using products containing these alcohols that are used close to the skin (toners, essences, serums and exfoliants) raises the risk of sensiti...

Combining Active Ingredients - What Can And Can't I Combine

A very common question is what actives can, and can't be combined? There are so many actives around these days and at some point you end up scratching your head about what you can and can't combine when it comes to some of these ingredients. When it comes to combining actives some factors to consider are tolerance, sensitivity levels and chemical interactions. Personally I would avoid combining actives unless you’re treating something specific like pigmentation/acne/etc, are well acclimated to actives (though still be cautious) and/or have been prescribed a combination of one, or more of the below actives.   I’ve been prescribed a few compounded serums containing a few of the below actives to treat some hyper-pigmentation. While my skin is not easily irritated this definitely was a shock but also manageable when prepared. Once you’ve built a tolerance to these ingredients (and do not have sensitivity issues) you can look at combining them strategically to get the b...

Serums, Actives and Chemical Exfoliants - How Frequently Do I Really Need To Use These?

A common question asked is how often do I need to use my serums or exfoliant? Serums and Actives:   Depending on the formulation and the issue you’re treating can vary how frequently you may need to use these to achieve the desired result. For example if your aim is to add hydration/moisture, maintenance or general anti-aging, realistically this only needs to be used between 2-3 days a week (either in the AM or PM not really both).  You could get away with more hydration/moisturisers like peptides, omega fatty acids, etc but even then there’s a limit to how much the skin can absorb and too much can lead to irritation.  If treating issues like scarring, hyper-pigmentation, these may require more frequent use of actives like Niacinamide, Vitamin C, Retinoids or brightening agents like Alpha Arbutin/Hydroquinone. A frequency of somewhere between 3-5 days per week to treat the issue, then reduced to 2-3 days for maintenance, unless directed by a profes...

Patting/Tapping or Rubbing, Which Technique Works Better?

Are You A Patter Or Rubber I think when applying products it's almost an automatic reaction to rub your products in. For many years it was for me. I had the privilege of working with Rae Morris in my early 20's, a well-known makeup artist who to this day does amazing natural/wearable makeup (If you're unfamiliar check out some of her work -Rae Morris). She realised my natural affinity for all things skin-related and gave me a few of the best tips of my life, and that I still use today.  The first was tapping or patting the product into the skin. The reason for this was it allowed for products to be directly deposited on the skin more efficiently, rather than being absorbed into the tips of the fingers more so than the face. Once I factored in the science behind dragging and pulling of the skin caused by rubbing, and the simple friction it created also leading to things like irritation/inflammation I embarked on a journey to only tap in my products. Over 15 years...
