Will the white patches on my face caused by Retin-A go away?

Topical vitamin A products can be harsh, particularly during the initial phase of use.  I recommend applying a heavy moisturizer after application to reduce irritation.  The white areas are like pityriasis alba from eczema but are due to the high irritation factor of the product you are using.  I also would recommend either starting with a lighter Vit A product, such as a strong retinol blend to get your skin used to turning over more rapidly.  Products with high concentrations of growth factor can eliminate the irritation of retinoids without using steroid creams.  Remember that a great skin regimen should focus on a balanced approach and be particular to your skin type.
