Drink plenty of water, should be half your body weight in water taken in daily. I use a teaspoon of Braggs apple cider organic vinegar in 10 oz glass of water each morning. I rarely eat processed foods and snacks like cookies potato chips basically anything that's boxed. Healthy skin starts from within (watch what you put inside your body) and then you can use external products to maintain outer appearance.
Facial/skin routine is simple, a facial cleanser, 100% Shea butter or cocoa butter a little bit of makeup and that's it. Adding too many products is a no go because my skin is sensitive and dry.
