Adapalene
"I have been using this product since it was made available without a prescription. 

If you are going to use it, be sure to read the instructions and warnings. 

This product has a period of time at the beginning of use that makes your acne worse and then clears it. I went through this process when I started taking Spironolactone, so I knew what to expect and I trusted that it would go away - it did. 

My skin looks and feels fantastic! I still get an occasional zit here at there - I'm pretty sure it's my fault as I'm a toucher/picker/popper. 

This is an easy product to add to your routine. Make sure to use it at night and wash off in the morning so you don't have to worry about sunburns. 

I highly recommend Differin."
