Skin care might be a science — but it varies so widely for everyone that it’s often hard to figure out what works for you without some trial and error. But there are a few widely accepted, almost universal skin care truths: stay out of the sun, drink plenty of water and start using retinol.

Even if your goal isn’t to look a decade or two younger, wrinkle-fighting retinol can work wonders for keeping your skin healthy, even-toned, plump and clear. In fact, it’s known as a miracle ingredient among dermatologists, many of whom we spoke to to find out exactly what retinol can do to benefit our skin, as well as the best retinol moisturizers, serums and eye creams on the market.

What is retinol?

“Retinol is perhaps the best studied ingredient we have to fight the appearance of fine lines and wrinkles,” says Dr. Joshua Zeichner, the director of cosmetic and clinical research at Mount Sinai Hospital’s department of dermatology. “It’s a form of vitamin A that stimulates our skin cells to encourage production of collagen and elastin. This strengthens the foundation of the skin and can improve the appearance of fine lines and wrinkles.”

In short: It keeps your skin working the way it did at its prime. Because retinol works to increase the turnover of your skin cells, it essentially means your skin cells reproduce at a faster rate, which increases collagen production, evens skin texture and reduces the appearance of fine lines and wrinkles, says plastic surgeon Dr. Julius Few. But it isn’t all sunshine and roses: “Retinols vary in quality, effectiveness and tolerability,” he says. And because retinol accelerates cell turnover, it can increase skin sensitivity: “The chief complaints of most retinoids are dryness, irritation and peeling,” he says. More on that below.

When should I use retinol?

Basically, right now. While most people start to use products like retinol when they see visible changes in their skin, Dr. Ava Shamban, a board-certified dermatologist based in Los Angeles and founder of Ava MD Dermatology, SkinFive Medical Spas and The Box by Dr Ava, says, “It’s almost never too early [to start using retinol because] boosting natural elastin and collagen production is prevention. Our levels of collagen begin to slow down around the age of 30 and those losses are much greater as we age and our hormone levels decrease, which is why women see the greatest changes with perimenopause and postmenopause.”

It’s never too late to start, either. Dr. Loretta Ciraldo, a Miami-based board-certified dermatologist and founder of Dr. Loretta skin care, points out that studies have proven that retinol can help even in very advanced aging skin: “A left-right arm comparison study of patients 80 years of age or older showed that 24 weeks of treatment with 1% retinol stimulated fibroblasts to make more collagen and also reduced collagen breakdown,” she says. In layperson’s terms, the power ingredient can even help the skin better repair itself well into your 80s.

Because retinol is powerful enough to cause dryness and peeling, Zeichner recommends you start by using it once or twice a week, and eventually work up to every other — then every night. “We know that the skin undergoes daily circadian rhythms, where specific activities occur in the morning and others in the evening,” says Zeichner, who recommends applying retinol in the evening along with a moisturizer. “Skin cell turnover and repair mechanisms are already at their max functioning at night. So it makes sense to enhance these activities by applying retinol.”

Best retinol creams

When it comes to retinol, some derms will recommend a topical prescription for Altreno Lotion, a high-grade, FDA-approved retinol that also helps with adult acne, but if you’re just looking to possibly even things out and get rid of fine lines and wrinkles, the derms we spoke to insist that an Rx isn’t always necessary.

Few’s own retinol cream is “designed to continually enhance skin’s texture to ensure firmness and smoothness.” Start with every third night, then work your way up to nightly use.

Best retinol serums

Retinol serums are a great alternative to traditional creams because they can be mixed with an inactive moisturizer. “Serums that incorporate hyaluronic acid, polyglutamic acid, ceramides or other hydrating and emollients are a good ingredient match for retinol since they can be drying or cause skin purging or irritation as the skin adapts,” Ava says. “Antioxidants are always a good pairing for retinoids.”

The benefit of a retinol serum over a retinol cream is that you can layer it under your favorite moisturizer, and preferably one that’s nourishing enough to help with any drying. Some serum formulas can also be less harsh on the skin, making them ideal for more sensitive skin types or retinol first-timers.

Ava recommends Instytutum RetinOil because of its granactive format. (That’s just a fancy way of saying your skin recognizes it easier than other forms of vitamin A, meaning that you’re less likely to experience irritation.)

“It delivers 0.5% retinol in a lipid replacement base to replenish skin’s natural lipid content that is often lessened both with aging and retinol use, since it strips away dead cells that store lipid between them,” says Loretta. “For normal/oily skin use it at bedtime. For normal/dry skin, start it every other night for the first two weeks. For sensitive skin, use this just twice a week at night for the first two weeks.”
