It's really hard not to get tanned in hot summer. Even if the weather is hot enough to make your brain collapse, you can't relax in the face of sun protection.

When it comes to sun protection, the first choice must be to apply sunscreen. However, there are many kinds of sunscreens on the market, not only sunscreen lotion, sunscreen spray and sunscreen stick, but also physical sunscreen and chemical sunscreen. It's really dazzling, I don't know where to start.

Fairy who don't know how to choose sunscreen, don't miss the next content.

If you want to choose sunscreen, you must first understand its principle.

According to different sunscreens, ultraviolet radiation can be blocked by absorption or reflection/scattering. So sun protection is divided into physical sun protection and chemical sun protection.

Physical sunscreens usually use powdered minerals as blocking agents, most commonly zinc oxide and titanium dioxide, which can reflect/scatter ultraviolet rays. Moreover, the physical sunscreen is not easy to dissolve, is not easy to be absorbed by the skin, has little irritation to the skin, and is relatively safe and mild.

However, most of the chemical sunscreens are synthetic, and the most common ones are ethyl hexyl methoxycinnamate, ethyl hexyl salicylate, octyl, humulus et al., which can absorb ultraviolet rays in different bands. However, chemical sunscreen is easily soluble in water and oil, which will be absorbed by the skin and easily lead to skin allergies.

Physical sun protection is not very good for the skin, but the texture is thick, and some of them will be greasy and fake white. But its ingredients are safe and mild. Therefore, it is suitable for children and people with sensitive skin.

Although chemical sunscreen is easy to cause allergies, its safety is relatively poor. However, it is easy to push away, does not appear false white, has a good sense of use, and is more suitable for people who like to pursue dryness and non-greasy.

In fact, physical sunscreen and chemical sunscreen are not absolutely good or bad. You just need to avoid the high-risk ingredients in sunscreen according to your skin type and preferences.
