Can Retin-A be used to treat eye bags?

Retin-A can be effective to treat issues on the skin, such as fine lines. It would not have an effect on issues under the surface of the skin, such as eye bags. An examination of you would be helpful to give you the best advice, but in most cases, bags under the eyes are caused by protruding fat. This can be treated with surgery to directly address the fat, or sometimes a filler can be placed under the bags to help camouflage them.
