Zinc oxide paste has also been popular for skin protection for thousands of years. For example, ancient Greeks used olive oil for this purpose, and ancient Egyptians used extracts of rice, jasmine, and lupine plants whose products are still used in skin care today.

To effectively protect against all the potential damages of UV light, the use of broad-spectrum sunscreens (covering both UVA and UVB radiation) has been recommended. The routine use of sunscreens may also reduce the risk of melanoma. Medical organizations such as the American Cancer Society recommend the use of sunscreen because it aids in the prevention of squamous cell carcinomas. Some chemical ingredients have also been heavily scrutinised for their toxicity and have thus been banned in places such as Hawaii and Thailand for their impact on aquatic life and the environment. Chemical sunscreen ingredients mainly work by absorbing the UV rays. Chemical sunscreens (also referred to as petrochemical sunscreens), use active ingredients that are typically derived from petroleum (e.g.Minerals mainly work by reflecting UV rays. Mineral sunscreens (also referred to as physical), use active ingredients that are minerals ( zinc oxide and titanium dioxide).Sunscreens are regulated in terms of containing an active ingredient that is of mineral or chemical origin:
Sunscreens are common supplements to clothing, particularly sunglasses, sunhats and special sun protective clothing, and other forms of photoprotection (such as umbrellas). Sunscreens come as lotions, sprays, gels, foams (such as an expanded foam lotion or whipped lotion ), sticks, powders and other topical products. A sunscreen with BP-3 is definitely better than no sunscreen.Sunscreen, also known as sunblock or sun cream, is a photoprotective topical product for the skin that helps protect against sunburn and most importantly prevent skin cancer. However, if you find a formula that you love and contains BP-3, we do not think that you should throw it away. Overall, BP-3 is probably our least favorite sunscreen agent and we prefer sunscreens without it. It can be used in concentrations of up to 10% in the EU and up to 6% in the US. On the up side, sunscreens are pretty well regulated in several parts of the world, and BP-3 is considered " safe as used" and is an allowed sunscreen agent everywhere.

If that was not enough, Wikipedia claims that BP-3 is nowadays the most common allergen found in sunscreens, and the always-trustworthy smartskincare writes that " have been shown in some studies to promote the generation of potentially harmful free radicals". In fact, a 2004 follow-up study to examine the estrogenic effect of sunscreens when used topically on the whole body found that "the endogenous levels of reproductive hormones were unaffected" (even though BP-3 could be detected both in plasma and urine, so its absorption is no doubt too good). Estrogenic activity was confirmed only in-vitro (in test tubes) and when taken orally by lab animals, and not when used topically as you would normally.
