Tretinoin is by no means new to the field of skin care. In fact, it was the first retinoid approved by the FDA to help treat and prevent acne. “Tretinoin is another topical retinoid, derived from vitamin A, which also helps prevent and treat acne,” says Libby. “It is more well studied for its anti-aging benefits and works to increase cell turnover, improve epidermis thickness and minimize fine lines, while improving discolorations and treating acne,” she says.
Unlike adapalene, you can’t buy over-the-counter tretinoin. This retinoid is only available with a prescription. One of the downsides of tretinoin is the length of time it takes to see results and the possibility of pesky side effects.
For example, if you have sensitive skin, this might not be the retinoid for you. Tretinoin works by irritating further to activate cell renewal, you may experience redness, irritation, blistering, and even a change in skin pigmentation. It is therefore important to use this product only under the supervision of a doctor. And even with the unwanted side effects, research shows that tretinoin helps reduce fine lines and wrinkles, corrects the texture and tone of the skin and even reduces hyperpigmentation.
