Breaking out from Retin-A
Retin-A gels are stronger than creams and sometimes more irritating. I don't know how often your dermatologist told you to use the product either. I might simply stop using the product and see if things clear up. If they do, you know it's the Retin-A. It usually takes about a month to see changes within the skin after starting (or stopping) a product. Consult your dermatologist for advice or a different product.
