I have been searching for a product with spf in it to wear daily, after a long and hard search I have found out that titanium dixoide is about the only one I can wear on my face everything else gives me a rash, the titanium still makes me a bit itchy but I can get away with if for a while. My skin has completely dried out because of all the irritation from trying different products on it. How important is it to wear every day. I am not an outdoors type, but if I am going to be outside I do put it on, as for aging I am going to age anyway and both of my parents look very young for their ages so I hope the old gene pool works for me too! I just think putting spf on you face everyday even in the winter might cause more damage than good because the only skin showing is the face and we need some sun for vitamin D and K. I am trying everything I can to wear it every day, I am just not sure if I am causing more damage than good. Any opinions on this>
