What is retinol — and why should you use it?
Retinol is a type of vitamin A that occurs naturally in the skin. When absorbed topically, enzymes in the skin convert retinol to retinoic acid, stimulating the production of healthy new skin cells. The ingredient became popular as an anti-ager when patients using it to treat acne noticed it not only got rid of their blemishes but also helped diminish wrinkles and reduce pigmentation. It’s also known to smooth the skin’s texture and provide a brightening glow.
“The use of retinol is core to any anti-aging regime, especially if you’re over 30,” says board-certified dermatologist Alexis Young. “Retinol breaks up the top dead layer of the skin and increases cell turnover, allowing smoother skin to shine through.”

New York-based dermatologist Joshua Zeichner suggests applying retinol two to three times a week, starting at the lowest concentration and adjusting accordingly.
“The body will develop a tolerance to retinol over one to two months — known as the retinization period — so any irritation experienced at the beginning of therapy should improve over time as your skin adjusts to the product,” he told Shop TODAY.
Young agrees that it’s best to start with a low percentage of retinol and then increase based on your skin’s sensitivity.
“If your skin tends to be sensitive and dry, then start with a lower strength like 0.3%, increase to 0.5% and then ultimately 1%, if you can tolerate it, over weeks to months,” said Young.
Can’t decide between a cream, serum, gel or lotion-based retinol? Most formulas are equally effective, so it’s just a matter of personal preference.
Does retinol have any side effects?
Given my roommate’s skin reaction, I wanted to know more about retinol’s potential side effects, including increased sun sensitivity, a burning sensation upon application, peeling, redness and dryness.
In the past, dermatologists have instructed patients to apply retinol at night because earlier formulations were sensitive to sunlight. However, modern-day retinol products tend to have gentler formulations.

“The new generation of products release retinol slowly into the skin to minimize irritating effects, giving flexibility of use whenever it fits into your daily routine,” Zeichner said. “Just be sure to apply it after cleansing and before moisturizing, distributing a pea-sized amount on your forehead, nose, cheeks and chin before rubbing it in.” He also added that a sunscreen with a minimum SPF of 30 is a must and should be applied on top of the retinol, while makeup can be applied over the SPF.
To further minimize side effects, Young recommends looking for retinol moisturizers that contain strong hydrating ingredients or using a separate moisturizer in addition to your retinol. Unlike prescription products, where the exact concentration of retinol is known, information about the percentage of retinol in over-the-counter products is sometimes nonexistent on the packaging.
“Companies don’t want to say their product is biologically changing the skin because then they’d have to be FDA regulated,” said Young. “So you’ll need to look for ingredients like hyaluronic acid and ceramides, which are very effective at adding and sealing moisture into the skin and preventing sensitivity. If a product is too irritating, switch to a different brand or use it more sparingly.”
Dr. Howard Murad, whose eponymous skincare line includes a retinol, argues the percentage of retinol itself isn’t always so telling.
“Oftentimes, it’s about the ingredient pairings which ultimately act as retinol boosters — meaning the percentage isn’t always the best way to gauge efficacy,” he told us.
Decades of scientific studies have revealed retinol’s skin benefits, but some wonder whether retinol thins the skin and causes chronic inflammation, leading to premature aging.
“The truth is retinol actually thickens the skin’s top layer, the epidermis, by stimulating collagen and elastin, but it can also thin the stratum corneum, the very top layer of the epidermis, which explains the retinol ‘glow’ that some patients experience,” said Zeichner. “The glow occurs because retinol improves light reflection off of the skin’s surface. Thinning of the stratum corneum will not ‘weaken’ the skin, but it can make it more sensitive to sunburn and physical trauma. So you’ll need to be careful when it comes to sun exposure, hair removal, facial scrubs or anything that exposes the face to trauma or irritants.”
“If you’re undergoing a chemical peel, facial waxing, or if you’re pregnant, hit pause on your retinol. But you should try to restart usage as soon as possible since tolerance to retinol could be lost,” adds Young.
So, how is the CeraVe Resurfacing Retinol Serum?
Truthfully, I’m mad at myself for not incorporating retinol earlier. The serum does sting for about 10 seconds upon application, and I did see some white flakes early on, but that’s about it. Better yet, the CeraVe Resurfacing Retinol Serum is expert approved.

“I like that it contains niacinamide and licorice root, effective anti-inflammatory agents that help improve the tolerability of a retinol, along with ceramides, which are critical to maintaining the skin barrier and preventing water loss,” Young said. “Plus, it doesn’t feel gritty or pasty like other retinol products, and one pump is the perfect dosage for the entire face.”
Adding this anti-aging ingredient to my skincare regime was an easy and inexpensive beauty move. I’m happy to say small areas of pigmentation have diminished and my skin looks fresher than ever. I’ve got a great glow on!
