Differin Acne Treatment Gel ($24, originally $36)
This treatment gel clears and prevents acne thanks to its adapalene formulation. Through Rx-strength acne retinoid, the gel not only helps to remove acne but also reduces the risk of the scarring and hyperpigmentation that comes with it. Of course, one of our editors tested it for a year and now has the most glass-like skin. You can read more about her experience in our Differin Acne Treatment Gel review.
Editor Quote: "I know you've probably heard beauty editors say it a million times, but: I rarely buy beauty products. However, there are a few rare occasions where I do whip out my credit card for a skin, body, hair, or makeup product. I gladly buy myself a refill of this Differin Gel every time I'm running low, which happens about every month and a half." — Jessica Harrington, beauty section lead
