Retinol works for acne by preventing clogged pores. You may still see pimples for the first couple of months of treatment – your skin might even look worse (this is sometimes referred to as the retinol purge). But if you stick with it, you'll see clearer skin.
Dry skin, sun sensitivity, and mild redness are expected when you start using retinol. If you already have sensitive skin or your dose is too strong, you may experience effects like (Leyden, 2017): Excessive skin dryness. Flaky or peeling skin.
Retinol (leave to absorb for 10-20 minutes)
Retinol is also an ingredient that should be left to absorb sufficiently into the skin before following up with another product. “It is important to leave a 10-20 minute wait time before applying the next product.
Most people who introduce retinol to their skin, experience severe breakouts, dryness, itchiness, and redness. The immediate side effects of retinol treatment can take the form of a surge in acne, blackheads, whiteheads, and rashes. This is termed retinol purging.
Regardless of your skin type or which product you use first, a layer of moisturizer should always be applied after retinoids.
You should always apply retinol at night, after cleansing, and before your nighttime moisturizer. Five minutes is enough to wait for your retinol to sink in before applying moisturizer; you want to layer them, not mix them.
Don't Mix: Retinol with vitamin C, benzoyl peroxide, and AHA/BHA acids. AHA and BHA acids are exfoliating, which can dry out the skin and cause further irritation if your skincare routine already includes retinol.
The telltale signs of retinol burn include skin that is red, irritated, flaky, inflamed, sore to the touch, and/or shedding. "You could also be experiencing breakouts or inflamed acne that is not usual for your skin," adds Idriss.
What Are Possible Side Effects of Retinol? Signs that your skin is not tolerating retinol include redness, dryness, itchiness, flaking, and peeling. "Retinol should only cause irritation for the first few weeks as your skin adjusts, which isn't enough time for skin thinning to develop.
She explains that retinol is another form of retinoid, which is earlier in the cascade process—the process begins with retinyl palmitate, then retinol, retinaldehyde, and finally retinoic acid.
Your Retinoid is Being Inactivated
Retinoids are inactivated by UV light, so must be applied at night. Additionally, retinoids can be inactivated by other topical skin care ingredients, most commonly salicylic acid. Avoid using products which contain salicylic acid in your night-time skin care routine.
The best thing to combine with a retinol is a moisturiser because it hydrates the skin while reducing the risk of irritation,” explains Dr. Mittal Gupta.
Skin purging happens when new ingredients, like retinol, promote increased cell turnover, which causes clogging and worsening breakouts. This is particularly the case as oil and debris that is trapped deeper underneath the skin comes to the surface.
Never rub the skin, as this can lead to increased irritation. After you've applied your retinol, wait at least three to five minutes before moving on to the next step. That amount of time gives your retinol plenty of time to be thoroughly absorbed into the skin.
Engelman agrees: "Retinol is the most potent ingredient that helps build collagen and elastin, which leads to tighter, smoother skin." This mixture has the added bonus of hyaluronic acid, which "can smooth, firm, and tighten the appearance of the skin," Dr. Bowe says.
This varies, but you can expect the purge to last anywhere from 2 weeks to 3 months. If you're seeing results for longer than 3 months, you might want to consult your GP or dermatologist. But first, be sure your skin concerns are definitely related to retinol…
Recommended Usage of Retinol & Lactic Acid
Alternate them by using a retinol product at night and a lactic acid product in the morning—or use a retinol product one day and a lactic acid product the next.
Can hyaluronic acid and retinol be used together? Unlike many other skin care ingredients out there, hyaluronic acid and retinol can be used in the same skincare routine. Not only that, but using them together can help to lessen the severity of the side effects that often come with retinol usage.
To apply a serum with retinol correctly, smooth it onto clean skin after you cleanse and before your moisturizer. Your serum will have a thinner consistency than your moisturizer, which is what determines the application order.
Should you use retinol under your eyes? Yes, definitely. While it is true that retinol – a form of vitamin A – is a powerful ingredient and the skin under your eyes is delicate, there's no reason why you should miss out on the amazing benefits of retinol.
A Retinol sandwich is just Retinol layered between two moisturiser treatments. Apply moisturiser on damp, cleaned skin to do this. Next, apply your Retinol product as indicated on the packaging, avoiding sensitive areas such as the eyes and mouth corners.
To do the retinol-sandwich method, rather going directly into your retinol after cleansing your skin, you start by applying a layer of moisturizer to damp skin. Once it's completely dry, you apply a layer of retinol. After giving the retinol time to absorb, you finish everything off with a second layer of moisturizer.
