![]() “There is evidence that they are absorbed by the body to varying degrees,” Dr. And, and this is extra important, chemical sunscreen is not inherently bad just because it’s called “chemical.” That in mind, there is still a decent amount of research that needs to be done to figure out how safe the chemicals actually are. The most important takeaway here is that a chemical sunscreen is better than no sunscreen at all. To put it simply, those ingredients are going to absorb the sun’s UV rays. Unlike mineral sunscreens that feature zinc and titanium dioxide, a chemical formula is going to include active ingredients “such as oxybenzone, avobenzone, octisalate, octocrylene, homosalate, and octinoxate,” says Dr. Once again, the “chemical sunscreen” classification boils down to ingredients. “It has been shown that for those with melasma or a predisposition to hyperpigmentation, blue light can cause increased, unwanted pigmentation-especially in darker skin types,” explains Dr. Iron oxides can help block blue light, which emitted from computer screens, as well as the sun. But in this lovely two-benefits-for-the-price-of-one special, you get an added layer of protection. Cosmetically, an iron oxide gives the liquid a tint and can compensate for the zinc’s white cast. Perhaps the most compelling reason to choose a mineral sunscreen, is the inclusion of something called iron oxides, which are included in most tinted titanium dioxide-based SPFs. Gymrek also recommends physical blockers (remember it deflects the UV rays) for people with rosacea, melasma, or hyperpigmentation. The Benefits of Mineral SunscreenĪ mineral sunscreen is typically going to be the best way to go for children or anyone who has sensitive skin- the active ingredients rarely cause an allergic reaction or irritation. The EWG has agreed that while more studies are needed to definitively determine if nano-zinc is dangerous, there’s currently no evidence that indicates the smaller molecule is harmful. On the flip side though, there’s some concern that the small size of the molecules can sink into the skin and cause harm. “These micronized or nano- zinc oxide sunscreens are preferred because they feel lighter, spread better, and leave less of a white hue on the skin after applying,” she says. Gmyrek explains that because zinc runs on the goopy, thick side, a lot of companies have made the molecule super, super small.
