I tried this product a few years ago and the irritation was so bad I had to stop. After trying almost everything else on the market I decided to give tretinoin a second shot. It cleared my skin.
This is what I did:
Put a pea sized amount of .025 tretinoin cream in your hand
Put about twice that amount of cerave pm facial moisturizer on top of the tretinoin and mix it thoroughly to form a paste
Apply paste to affected area at night
Moisturize with cerave again in the morning
My skin was almost completely clear in a week. I think the lotion helped my skin absorb the tretinoin better. Regardless, it really helped and the moisturizer helped reduce the facial redness I had experienced before! I sugest people give this a shot for a few weeks.
