First, choose the gentlest formula (again, retinyl palmitate or retinol), and start slowly—apply it just one night a week for one week, two nights a week for two weeks, three nights a week for three weeks, and then every other night (for sensitive skin) or every night (for “tough” skin) indefinitely.
He recommends starting with no more than every other day for the first 2 weeks. If, after the first 2 weeks, you don't see any side effects, he says you may want to move up to “2 nights on, and 1 night off.” After a month or so with no side effects, you can likely use it every day if you want.
For beginners, most dermatologists recommend a retinol with a concentration of 0.25 percent to one percent to see results.
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.
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.
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.
While prescription-strength retinoids may have an effect in a matter of weeks, it can take up to 6 months for OTC retinols to produce the same results. You may notice a difference in conditions like acne after 12 weeks, but sun damage and signs of aging can take much, much longer to improve.
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. As for benzoyl peroxide and retinol, they cancel each other out.
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.
To help your retinoid work better, some dermatologists recommend applying it directly after cleansing before any other treatment serum or moisturizer.
“AHA, BHA, retinol, and benzoyl peroxide can be mixed with moisturizing ingredients like hyaluronic acid, ceramides, and rosehip oil to get effective results — just ensure you are not using retinol as well as AHA or BHA's during the day," says Graf.
Dr. Mariwalla says coating your skin with Vaseline after applying retinoids or AHA acids would increase penetration of these ingredients, potentially leading to irritation.
Niacinamide and retinol can be combined in one product, which may be easier and more convenient. But they're also available as separate products. If you're using these ingredients in separate products, it's recommended to apply niacinamide first and to then follow with retinol.
Mix It Up. One tip to help your skin adjust to retinol is to mix your retinol with your face moisturizer and then apply it to your skin. This allows the retinol to be a little gentler on your skin, which is great if you have sensitive 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.
Hyaluronic acid is best if they're looking to moisturize dry skin, while retinol works better by encouraging better skin by boosting collagen production. They have several benefits that can work in tandem for better results, though patients need to be careful with the exact formulations they use.
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.
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.
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.
Do not use this medicine in or around the eyes or lips, or inside of the nose. Spread the medicine away from these areas when applying. If it accidentally gets on these areas, wash with water at once. Before applying tretinoin, wash the skin with a mild soap or cleanser and warm water by using the tips of your fingers.
The best product you can use in conjunction with retinol, according to Dr. Zeichner, is a moisturizer, which can help hydrate skin and reduce the risk of irritation from retinol. “Some people even prefer to mix their retinol with a moisturizing cream to dilute it out,” he says.
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.
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.
