I try not to recommend brands of products - only TYPES of products. Your skin is dry from the Retin A! that's what it is supposed to do; dry out your skin and supposedly, the underlying acne caused by clogged pores.
First, you need to cleanse the skin of all the dry flakes, and for that, I recommend an Oatmeal Facial Bar for cleansing the facial skin. Secondly, I also recommend a mixture of 4 parts jojoba oil to 1 part vitamin E oil to rehydrate and condition the skin. The jojoba will open the pores and help to clean out the clogged pores, then draw the healingproperties of the vitamin E in after it. After you apply this mixture, wait at least 10 minutes to be sure it has absorbed into your skin. If there is still residual oils on the surface, you can wipe off the excess with a soft, absorbent towelette. Wait a couple of minutes, then apply your Retin A. Only apply the Retin A at night when it will do the most good. Apply the oil before applying your makeup, but be sure to use only a few tiny drops as a little goes a long way. Allow it to absorb before applying your makeup, or you will feel 'greasy' all day long.
For everyones information, I am going to turn 55 years old in August, and I am told that I look way younger than that - even with the white hair

I can tell you, the jojoba and vitamin E WORK!
