Longtime lovers of this product — based on over 50,000 reviews — already know of its power. It features adapalene, a topical retinoid that works to treat existing acne and prevent new acne by “removing dead skin cells and shrinking oil glands,” Dr. Ariel Ostad, a cosmetic surgeon based in New York City, previously told HuffPost. Ostad added that this ingredient also helps restore your skin’s tone and texture, freeing it from pore congestion.

Board-certified dermatologist Dr. Macrene Alexiades noted that Differin is intended for people who need a stronger skin care treatment.

As an adapalene-based product, this gel is designed to help with severe acne and can promote collagen production or improve the appearance of sun damage. The reviews will tell you this isn’t an overnight miracle product. “I began noticing real improvements after consistent use over several weeks my skin feels clearer, more balanced, and far less prone to breakouts,” one wrote. ”...It requires patience and consistency, but the long-term benefits are absolutely worth it.”

If you’re new to using retinol, the experts say it can cause flaking and irritation in the beginning, something that many reviewers refer to as the “purge” stage, which ultimately leads to healthy, happy, and better-looking skin.
