Why Adding Retinol to Your Beauty Routine Will Change Your Skin

The vitamin A derivative is a go-to for a reason: it comes in prescription and over-the-counter strengths and works to reverse common skin concerns. "It combats all the signs of aging in addition to signs of hormonal imbalance," Dr. Henry said.
Retinol kicks your cell turnover into overdrive, exfoliating the skin — a move that can effectively reduce acne, fade dark spots, and iron out fine lines and wrinkles. "As it is exfoliating, retinol helps to unclog pores and shrink the oil glands," she said. "When your oil glands shrink in size, less acne is produced."

Retinol is safe to use on all skin types; however, Dr. Henry encourages you use it differently if you have dark skin. "People with darker complexions should be more careful and move slowly with retinol," she said. "If you overuse it, you can experience retinoid dermatitis, which is a rash that can become hyperpigmented in darker skin." If you have severe cystic acne, consult your dermatologist before trying out retinol.

There are a few things you can do to get the most out of your retinol treatment without causing damage to your skin. Dr. Henry's number one tip? Hydrate, hydrate, hydrate. "It's normal to experience dryness when using retinol because it shrinks oil glands," she said.

To avoid excessive dryness, she recommends using a noncomedogenic moisturizer that won't clog your pores. "Once you are incorporating tons of moisture into your routine, you can slowly work your way up to using retinol daily." Some of Dr. Henry's favorite moisturizers for dry skin are Cetaphil Moisturizing Lotion ($17) and Clinique Moisture Surge 72-Hour Auto Replenishing Hydrator ($19). If you're looking to add retinol your Summer skincare lineup, though, don't forget sun protection. The ingredient does slightly thin out the skin, so to avoid damage, be sure to apply sunscreen every day before leaving the house.
