Can Retin-A Thin the Skin?

Retin A has been studied extensively and its regular use normalizes the statum corneum of the epidermis and thickens the second layer of skin called the dermis. It improves photoaging and diminishes dark spots. Skin dullness is brightened in just weeks. It must be used with a sunscreen daily and I always add an antioxidant to the sunscreen in the morning. I also like peptides or growth factors at night with the Retin A, which can prevent the dehydration of the skin and the barrier disruption that can give the illusion of thinner skin. Using Retin A in your 20's is the best way to PREVENT aging of the skin. I suggest you see your dermatologist.
