This product has Retinol in it, which, if you haven't started using in your 20s, you should. Retinoids have come a long way and they can help fight everything from wrinkles to acne by accelerating cell turnover! There are a few things to note here, though. For one, only use this at night and do not let it touch your eyelids or under eye. You should also follow this up with a lightweight moisturizer to help blend and dilute it so you don't irritate your skin.
