This cream has many uses. The zinc oxide in it does not enter your bloodstream, rather it stays on top of the skin where it does the most good. Sun protection, it has reflective qualities, acne help, an astringent, it inhibits excess oil production, diaper rash, it has therapeutic wound healing properties. I've added organic unrefined oils and butters, beeswax, vitamins. All of these oils have SPF ratings. Emollient, protective, healing, turns clear after applying. Apply often, especially after sweating or swimming. Wearing protective clothing when in the sun is your best protection against burning. Over 3 oz.
