Smooth, hydrated skin reflects light most efficiently. So exfoliation and moisturization are key. Rest also revs up glow, during sleep, growth hormone is stimulated leading to skin repair and collagen production. But if you’re lacking in the sleep department and skimping on your skin care regime the best way to fake it is with my favourite product; Strobe cream by M.A.C. This cream is awesome in a tube! In the winter you can apply this cream all over your face for a healthy glow. In the summer months you may not need it all over unless you have really dull skin. So in this case, just apply it to your upper cheek bones and on the bridge of your nose. This product is great under make-up or all alone. It smells great too.
