Adapalene
"It will worsen for the first two weeks. After that , you'll clear up. Believe me I had the worst acne and I had never had this before in my entire life. My face was full of big , cystic acne , a lot of pustules and they're really awful! I am into adapalene 0.3 % for 6 weeks now and I am literally close to clear skin. I had a slight skin discoloration due to the scarring but I can see that a lot of these had faded. PATIENCE AND CONSISTENCY are the keys. Stick to it and have faith and you'll clear in no time. I love this product."
