I am attracted to Forah because of its plastic free container and reef safe ingredients. Unfortunately, the 10% zinc oxide and 7% titanium dioxide is not enough to protect me from burning. I live in Park City UT at an elevation of 6600ft above sea level. I just read that the FDA is finally approving bemotrizinol which I understand provides reliable protection and also reef safe. Perhaps that’s an ingredient to consider? Plastic free packaging is very important to me as well as environmentally friendly ingredients and so far Forah is the only sunscreen product that covers both so I will continue to check out your products, hoping that Forah will offer a sunscreen that can protect at high altitudes.
