Don't Mix: Retinol with vitamin C, benzoyl peroxide, and AHA/BHA acids. AHA and BHA acids are exfoliating, which can dry out skin and cause further irritation if your skincare routine already includes retinol.
She also says to stick with gentle cleansers (she likes CeraVe), and to always follow your retinol with a moisturizer, especially those with hyaluronic acid and ceramides. If your skin is really irritated, you can try buffering, where you apply moisturizer before retinol to reduce side effects.
When using a retinoid, you should use acid-based products and Vitamin C in your morning skincare routine only. But remember that using different exfoliators can lead to redness and irritation, especially when you first start using a retinoid, so consider sticking to a simplified skincare routine when starting out.
Pairing the two ingredients is safe and can make retinol easier to use. Niacinamide helps hydrate the skin, which reduces the risk of irritation caused by retinol. Niacinamide and retinol can be combined in one product or used as separate products.
The truth: You can use vitamin C with retinol and retinoids. Get them as separate products so you can tailor the concentration of each and use them at the right time of day. Although vitamin C can be used day or night, it is ideal for daytime use, while retinol and retinoids should be applied at night.
Using niacinamide before retinol works well. So does combining them into one product. A 2016 study found that a product containing retinol, niacinamide, hexylresorcinol, and resveratrol improved fine lines, sallowness, wrinkling, hyperpigmentation, and skin tone.
Retinoids work best if you use them daily. Specifically, they should be used at night because some types are deactivated by light and air. It's important to start slowly and allow your skin time to adjust. Using too much too quickly can cause redness, dryness, and irritation.
And now another rule to keep in mind: Many prescription-strength retinoids suggest users wait upwards of 20 minutes post-cleansing before putting retinol on their skin and 20 more minutes before putting anything else on, according to Reddit.
Rouleau says the best time to use a scrub is in the morning. Overnight you've loosened up dead skin cells with your glycolic acid or retinol products, making the morning a perfect time to brush them off.
Regardless of your skin type or which product you use first, a layer of moisturizer should always be applied after retinoids.
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.
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.
Apply topical retinoids
Retinoids, which are topical vitamin A-based derivatives, may help reduce fine lines and wrinkles by increasing collagen production. If you use retinoids on your face, extend the treatment area to your neck and chest at night. Retinoid products are available by prescription or over the counter.
What Are the Benefits of Combining the Two? Good news: Retinol and hyaluronic acid actually have a synergistic effect. “They can be combined so that the benefits of retinol can be achieved more easily with concomitant use of hyaluronic acid, which helps to prevent retinol irritation,” says Hartman.
When it comes to mixing all three together, the best order to apply them is by starting with retinol, followed by hyaluronic acid, and finally niacinamide. By applying retinol first onto a fully cleansed skin the ingredient can penetrate into the lower layers.
You should use hyaluronic acid after retinol. And to maximise the benefits, you should use retinol first and then wait at least 30 minutes before applying hyaluronic acid.
To apply a serum with retinol correctly, Smooth it onto clean skin before your moisturizer. Your serum will have a thinner consistency than your moisturizer, which is what determines the application order.
But rather than using your standard retinol cream, it's best to use a product formulated specifically for the delicate skin around the eyes. "The under-eye area is quite sensitive as it is some of the thinnest skin on the body," explains New York City-based board-certified dermatologist Anthony Rossi.
The problem is, retinol can be irritating when applied straight to the lips (so keep your prescription-strength cream off your mouth for the time being). But Verso's formula contains a gentle derivative, called retinol 8, which can reduce the appearance of fine lines around the mouth overtime.
Using any form of retinol makes your skin more prone to sunburn. Sun damage combined with retinol burn is a recipe for redness or discoloration, inflammation, and more.
Also avoid retinol if you're going to be spending a lot of time in direct sunlight without proper sun protection. Retinol can make your skin more sensitive to the sun, so it's important to use sunscreen with at least SPF 30 every day — even when it looks cloudy.
After two to six weeks of using tretinoin, it's usually okay to start using an exfoliant. However, it's best to use exfoliating products as sparingly as possible while using tretinoin to avoid potentially irritating your skin.
Retinol, salicylic acid, glycolic acid—all effective ingredients that can improve the look and feel of your complexion. But they can lead to irritation, and when used too close to your delicate eye area, that irritation can lead to bags.
But one such 'rule' we weren't aware of until now, is that retinol needs a decent amount of time to absorb. According to skincare guru and best-selling author, Caroline Hirons, you should allow 20 plus minutes before moving on to the next step of your routine.
It's best to apply Vitamin C before Retinol, as Vitamin C has a lower pH than Retinol. Once your skin absorbs the Vitamin C serum, your skin will return to its regular pH levels after 30 minutes or so. (You want your skin to return to its normal pH levels so vitamin C doesn't lower the pH of retinol.)
