What are the effects of alcohol in sunscreen

When we buy sunscreen, we should not only look at the SPF of the sunscreen, but also pay attention to the alcohol content. The higher the SPF, the stronger the sun protection ability. However, if the alcohol content is too high, it is not suitable for all of us. Everyone's skin sensitivity is different. People with sensitive skin must pay attention to the alcohol content in the sunscreen. So, what are the effects of sunscreen containing alcohol?

Generally, cosmetics suitable for oily skin contain alcohol ingredients, which are used to control oil, reduce inflammation and remove acne. However, long-term use will cause the skin to become loose, the pores to become larger, and it is easy to cause skin sensitivity. Be sure to buy good quality sunscreen. Some sunscreens not only fail to protect against the sun, but also cause certain chemical reactions under light, which can further damage the skin. It is recommended that if you do not need to be outdoors for a long time, try not to apply sunscreen on your face. It is enough to use day cream, isolation cream or foundation with sun protection effect.

Sunscreen can be divided into physical sunscreen and chemical sunscreen. However, chemical sunscreen has better skin feel and visual effects, while people with sensitive or extremely dry skin are more suitable for physical sunscreen.

Physical sunscreen

Using sunscreen particles, a protective layer is formed on the skin surface to reflect the light waves in ultraviolet rays that may cause damage to the skin, thereby protecting the skin. Physical sunscreen particles generally stay on the skin surface and will not be absorbed by the skin, so the burden on the skin is relatively small and it is not easy to cause skin sensitivity.

Chemical sunscreen

By combining certain chemicals with cells, the part of ultraviolet rays that may cause damage to the skin is absorbed before the cells are damaged, so as to achieve the purpose of sun protection.

Long-term use of alcohol-containing skin care products

First, alcohol is very volatile, and when it evaporates, it will take away the moisture on the skin and make the skin dry.

Second, alcohol with a high concentration has a strong decomposition ability. While decomposing facial oils, it will also destroy the skin's own water film, making the skin fragile and sensitive.
