You'll likely want to use retinol once or twice per week initially and work up to using it more than that. The reason: Retinol can initially be drying, especially if you have sensitive skin, so it's a good idea to give your skin some time to adjust to the change in your routine.
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.
Use retinol once or twice a week at first to see how your skin reacts, and gradually work up to every other day or three times a week. Another key tip for using retinol is to incorporate it into your nighttime skincare routine only, as it makes your skin more sensitive to sunlight.
“If you're overusing your retinol, or if you're using a retinol that's too strong for you, it can lead to peeling, irritation, and excessive dryness, which may have led to retinol's association with skin thinning,” she says.
Pending potency, OTC retinol can take up to six months to see results." That's not to say you won't see any benefits upon the first few uses. Nussbaum explains that in the short term, the benefits are that your skin will be exfoliated of dead skin cells and your pores will be unclogged.
Can you use retinol every day? Start slow. If you're a new user, your skin may only be able to tolerate retinol once every other day or so. As your skin gets used to retinol, you can apply it more often.
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.
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.
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.
"[but] best to re-start your retinol again when you can." Most dermatologists recommend using it at least twice weekly to see results.
While there's no right or wrong age to begin using retinol, most dermatologists recommend fitting it into your skin care routine during your 20s. The reason? "The production of collagen fibers starts to decline in our 20s," explains Dr. Allison Arthur, MD, FAAD, at Sand Lake Dermatology Center.
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.
So, should I use vitamin C or retinol for wrinkles? Well, when it comes right down to it, the choice is really in what you're looking to do for your skin. While vitamin C is incredible for the skin because of its ability to help brighten and improve hyperpigmentation, the best active ingredient for wrinkles is retinol.
Apply your vitamin C first, since it has the lower pH of the two. Then, wait half an hour before you apply your retinol. Incorporating the waiting period allows your skin's pH to return to normal, so each ingredient can work at its intended pH.
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.
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.
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.
L'Oréal Paris RevitaLift Night Serum with Pure Retinol
Goldenberg's go-to recommendation for timing between serums and moisturizers is about one minute. This wait has the same reasoning: Sixty seconds — give or take — gives each product a moment to delve into your pores.
A formula with retinol, like the L'Oréal Paris Revitalift Triple Power Eye Treatment, should be applied after your serums and before moisturizer due to its consistency.
Use Exfoliants Sparingly After the Adjustment Period
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 (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.
Retinoid or Retinol and Salicylic Acid
But on its own, each can dry out the skin, so together they should be combined with caution. The risk is overdrying, which can lead to irritation and make the situation worse.
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.
"Retinol helps eliminate and reduce signs of aging, improve appearance of fine lines and wrinkles and improve skin texture, which is a must for flawless-looking skin.
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.
