You’ve no doubt heard about retinoids. They’re the skincare ingredients we dermatologists consider a gold standard for treating acne and skincare gurus can’t stop raving about. With so many doctors and beauty companies on the lookout for the next big thing, why do retinoids, which have been around for decades, have so much appeal? The answer is simple: they work.
Retinoids are medicines that are derived from Vitamin A and are extremely helpful in the treatment of acne. Because they occur naturally in the skin, our skin cells have receptors for retinoids. When a retinoid binds to one of these receptors, internal cellular signals trigger a cascade of events that result in numerous beneficial effects on the skin. These include:
Dermatologists first began using retinoids to treat acne in the 1960s and in the decades that followed retinoids became one of the most-prescribed treatments for acne globally. In 2016, the FDA approved the over-the-counter use of Adapalene, a third generation retinoid.
Retinoids are very tolerable for most people. However, because they can result in irritation and dryness, people who have very dry or sensitive skin need to be careful when using a retinoid. In addition, since retinoids cause sensitivity to the sun, those who are averse to wearing sunscreen should avoid using a retinoid.
