Problems solved by technology

However, since general sunscreen products contain chemical sunscreens, especially products with high SPF, the content of chemical sunscreens is relatively high, and chemical sunscreens will be attenuated by absorbing ultraviolet rays, because chemical reactions occur on the skin, So it is irritating to the skin
Moreover, chemical sunscreen itself is a kind of photosensitive substance, and improper use can also stimulate the skin and cause photosensitivity reactions, etc.
