Can Retin-A be used for acne on the chest and back?

Retin-A can help with acne breakouts on your body and face. Just keep in mind that the skin in the chest area is extremely sensitive and there will be some irritation.  Exposure to sunlight including tanning beds should be avoided while using the product due to heightened sensitivity and increased probability for hyperpigmentation or sunspots.       I recommend for you to do the treatment under close supervision of a skin care professional. Please keep in mind there are other options to treat this condition such as laser treatments, microdermabrasions, chemical peels, Blu-u-light and vitamins to name a few.
