Is it okay if I mix zinc oxide powder in my lotion to get an effective sunblock. I use Aveeno Daily Moisturizing Lotion (which is a great lotion). Also, would I have to preserve it in the refrigerator or something? Thanks for your reply. :)
Hello again Ria,
I am NOT sure just how well zinc oxide mixes with water alone. Equally unsure about "shelf life."
Whatever you use as a sunscreen should help block UV radiation AND help keep your skin moist. This combination is NOT likely to occur with a mixture of zinc oxide and water.
The best sunscreens, containing sunblockers should contain a base of coconut oil, shea butter or some other natural oil.
Best of Health,
