Yeah, inorganic or physical sunscreens, whereas the chemicals are considered organic or chemical sunscreens. Totally right.

Yeah. Historically, it had been thought that mineral or physical sunscreen, zinc, zinc and titanium sunscreens, worked by basically acting as a metal reflecting shield. For the most part, that thinking is not incorrect. There was a new study that showed that they work by actually absorbing them, but not having any sort of chemical change.

So the way chemical organic sunscreens work is they absorb the ultraviolet radiation, they undergo a chemical reaction to reduce its energy and dissipate that energy as heat. So chemical sunscreens work by actually absorbing it and undergoing a change, whereas mineral or physical sunscreens don't do that.

I still think of them simply as minerals basically shield the skin like armor, whereas chemicals act as a sink and undergo a change to reduce that energy. So that's kind of the simplistic way that sunscreen, topical sunscreens work.

Yeah. In fact- Physical barriers like shade, clothing, hats have been shown to be more effective than topical sunscreens for several reasons. But there are many ways to protect your skin, and you have to ask why you're protecting your skin. So is it because you're worried about premature aging? aging, photo damage, and things like of that nature? Are you worried about your risk for skin cancer?

By and large, there are many other forms, both physical blockers and certain things in the supplement world that can protect your skin. For example, I myself take a product called sun powder that provides an internal sun shield and allows me to be in the sun longer. without the need to reapply or if I can't reapply.
