Review (5/5): Great product, I use Retin A and it is gentle enough for me to use.
I have used the Retin A for about 20 years and occassionally have the typical problems with skin flaking. I bought mechanical device at Target and the refills from Amazon. I use it 3-4 times a week. It is great. It is gentle enough that it doesn't cause problems with my sensitive skin because of the prescription cream, and it does a great job of getting rid of the dry layer. My skin really looks better than it has in years. I get the refill puff from Amazon's "subscribe and save" unit. You can find it under search. They send a box automatically, for whatever time period you choose, there is a discount for buying it from "subscribe and save" and they don't charge for shipping! If you do a search for the product and the subscribe and save it should show up. Sorry to turn this into a commercial for that program :~)
