Hello, 

When treating acne-prone dry skin it's essential you are still hydrating the skin and nourishing the barrier. Oftentimes acne specific products work to dry the skin out to help with oil control, but when you already have dry skin you will want to make sure to keep it hydrated. Have you had the opportunity to see an esthetician? They will be able to evaluate your skin and set you up with a proper treatment plan. 

Have a wonderful day!
