My experience with retinol: before & after

My retinol journey is an interesting one. As someone who has PCOS, I'm no stranger to experiencing breakouts that would leave me with persistent scarring, pigmentation, rough skin texture and a dull-looking skin tone. After consulting multiple board-certified dermatologists and aestheticians, I was advised to start using retinol – in the form of a face serum or a moisturiser.

I listened, and my results speak for themselves. After just four weeks of religiously using the dermatologist-recommended Medik8 Crystal Retinal serum, my skin went from looking inflamed and bumpy to smooth and plump. Initially, I was a tad worried that my sensitive skin may not pair well with a retinoid formula, however, let me assure you that it surprised me in the best way possible.

Does retinol help with acne?

Due to its anti-inflammatory benefits, one of retinol's commonly known benefits is that it can indeed help minimise the appearance of acne and speed up the healing process. Plus, thanks to its smoothing properties and its ability to accelerate cell turnover, retinol can also smooth out skin, which should in turn help with older acne scars and rough texture.


What strength retinol should I buy?

Professionals usually recommend starting out with the lowest concentration available and work your way to the stronger formula over time once your skin's tolerance adapts to retinoids. You would also do well to remember that beginners should start using retinol once a week for a few weeks, then move on to using it a few times a week until eventually working your way up to applying it once every night as part of your evening skincare routine. That said, if you had any specific skin concerns, we'd definitely advice consulting with your dermatologist prior to purchasing a retinol serum as they may recommend a prescription retinoid formula instead.


How long does it take retinol to have an effect?

As is the case with most active ingredients, you should be able to see results within 3-8 weeks of using retinol, depending on your skin type and the formula's concentration. You may find that some formulas may not be suitable for your skin type so we'd recommend switching to another product rather than keep using it if it irritates or dries out your skin.


How to use retinol correctly

Most dermatology experts recommend easing into retinol serums and creams, starting with one or two applications a week to build up your tolerance. You can also try buffering – i.e., sandwiching retinol between two layers of moisturiser – to keep retinol burn, dryness, flaking and breakouts at bay. Apply a pea-sized amount and take it from there.

It's also worth noting that retinol works best when used at night. “Most retinoids are not stable in the sun,” says Tsippora Shainhouse, MD, a board-certified dermatologist in Los Angeles. Not to mention all retinoids can make your skin more susceptible to sun damage due to their exfoliant properties, so be sure to wear a reliable sunscreen every day, she adds. You may also want to refrain from using too many exfoliating products with your retinol, so it might be a good idea to take it easy on products that contain AHAs, BHAs or glycolic acid.


When should you start using retinol?

30s or late 20s has long been considered the most suitable age to start introducing retinol as part of your skincare regimen to target the visible signs of aging, though many people choose to do so earlier rather than later for other concerns, such as acne or rough skin texture.

In other words, there's no particular rule as to when you can and should start using a retinol serum, so feel free to start using it if you’re approaching your mid-20s and feel as though you’d benefit from it. Make sure to consult with your dermatologist if you have specific conditions such as rocasea or eczema.
