Problems solved by technology

[0005] The particles used for physical sunscreen do not need to be absorbed, and the burden on the skin will be relatively small, but the disadvantages are also obvious. The particles are relatively large, appear white on the skin, and are sticky and greasy. Although the current workmanship is much finer than before, it is still This shortcoming is still not completely overcome, especially for people with dry skin, the moisturizing properties of physical sunscreens are too poor, and special makeup removal is required, and ordinary facial cleansers cannot clean thoroughly
Chemical sunscreens need to be absorbed, so they can take effect after 20 minutes of application. Generally, they are transparent and refreshing, but some people are more likely to be allergic to certain ingredients
