Because retinol can cause minor skin irritation, such as redness and flaking, we recommend starting slowly with a once-a-week application and working up to two or three times a week.
Begin in Your Mid 20s or Early 30s
"Your mid-twenties are a great time to start using retinol," says Ellen Marmur, M.D. "Many patients who have used it for years swear by it."
The truth is that even if you're in your twenties, you're not too young for retinol. Age just doesn't matter. Because it's not only for anti-aging, but it also works for acne. Retinol, and prescription retinoids, are commonly used for getting rid of breakouts—especially in teenagers.
“Absolutely!” says Dr. Nichols. “Retinol is safe to use for men or women in their 20s to help boost collagen and reduce signs of premature aging, such as creepiness, age spots, and fine lines.”
But all ages can reap the rewards of a retinol-infused beauty routine. “Dermatologists use retinoids for teens with acne, so when I prescribe it I will often explain the long-term benefits and will recommend that they continue to use the retinoid even after I have cleared their acne,” says Carroll.
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.
“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.
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.
Start thinking about retinol...but definitely wait till your late 20s. All derms will agree that the earlier you start addressing signs of aging, the better off you'll be. "As you enter your 20s, early signs of sun-damage and aging show on the skin," says Rachel Nazarian, M.D., at Schweiger Dermatology Group.
Chronic toxicities from long term therapy with retinoids may result in skeletal abnormalities, usually mimicking diffuse idiopathic hyperostosis syndrome. Furthermore, the chronic use of retinoids in children may inhibit their growth due to premature epiphyseal closure.
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.
Retinoids reduce fine lines and wrinkles by increasing the production of collagen. They also stimulate the production of new blood vessels in the skin, which improves skin color. Additional benefits include fading age spots and softening rough patches of skin.
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.
In theory, retinol makes your skin cell turnover faster. The increased cell turnover temporarily sloughs off more dead skin cells. This creates a lag time before new, healthy cells come to the surface of your skin. Your new skin is exposed before it's ready, and redness or discoloration, and irritation is the result.
"[but] best to re-start your retinol again when you can." Most dermatologists recommend using it at least twice weekly to see results.
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.
Remember, that 'retinoid uglies' are likely to be temporary, and it will take time before you see the end result. You have three skin layers—the epidermis, dermis, and subcutaneous tissue. Your epidermis is your visible layer, and renews approximately every 28 days.
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.
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.
Who should skip retinol? “Retinols can be a beneficial addition for most skin types, but it isn't a one-size-fits-all approach,” Panzica says. Board certified dermatologist Zenovia Gabriel, MD, notes that “people with sensitive skin conditions like rosacea cannot tolerate really strong topicals like retinols.”
Gaboardi notes that retinol can work by increasing blood flow to hair follicles in the scalp, in turn encouraging hair growth.
Again, there is no definitive evidence that topical retinoids lead to cancer or reproductive toxicity, but the evidence we do have is pretty much on par with that of parabens.
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.
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.
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.
