Since this is a prescription retinoid, be sure to consult your dermatologist before adding it to your skincare routine.

BuzzFeed Shopping Editor Natalie Brown tried this on her own skin! Here are her findings:

“1. One pea-sized application per day is sufficient.

2. It is just as effective above Moisturizer as if you were applying it directly to your skin.

3. Apply it at night. If you use it, you MUST use sunscreen every day!”

Promising review: “This product is a MAGIC ERASER for acne. This is the only product that works for my acne. It dried out my hormonal acne in one night! So I have mild hormonal acne due to menstrual cycle, but after using this gel every night and following the directions on the package, really helped me get rid of acne and dark spots. This product did not cause me to break out the first time I used it or later. This one tube lasted me a few months and a few days longer. I love the results and will buy another tube if my acne comes back, but for now I have clean and clear skin. Thank you, Differin!” —KARTHICK RAVI
