Can sunscreen really protect you from the sun? Do these 6 things to effectively protect yourself from the sun

Many girls apply sunscreen all the time in the summer, but after a summer they find that their skin is still getting darker. This can't help but make many girls start to question, can sunscreen really protect against the sun?

Does sunscreen really protect against the sun?

Sunscreen can really protect against the sun. Sunscreen is divided into two types: physical sunscreen and chemical sunscreen. Physical sunscreen uses sunscreen atomic particles. When the user applies physical sunscreen on the skin, the sunscreen forms a sunscreen film on the skin, which reflects sunlight and achieves the purpose of sun protection. Chemical sunscreen uses the molecules of chemical sunscreen to absorb ultraviolet rays in the sun, so that the ultraviolet rays are absorbed and then released at a lower energy, thus avoiding direct damage from ultraviolet rays. Sunscreen can provide sun protection to a certain extent, but only when it is used correctly can it achieve the desired effect.

Which is better, physical sunscreen or chemical sunscreen?

Theoretically, physical sunscreen is better than chemical sunscreen, but most sunscreens on the market are chemical sunscreens, and chemical sunscreens have a fatal flaw. That is, long-term use will cause skin sensitivity to chemical sunscreens, causing damage to skin cells and skin structure. In particular, the content of lead and mercury cannot exceed 0.5. The higher the chemical sun protection factor, the higher the lead and mercury content will be. Long-term use may cause skin cancer after several years.

Apply sunscreen correctly to protect against the sun

1. Clean your skin, apply an appropriate amount of moisturizing lotion on your body, and do a good job of moisturizing your skin;

2. 30 minutes before going out, take enough sunscreen and apply it evenly on the skin. Be sure to pay attention to the technique when applying the sunscreen, push the sunscreen parallel to the skin, and remember not to apply it by patting or massaging;

3. Pay attention to small details when using sunscreen. All skin exposed to the sun needs to be applied with sunscreen, otherwise it will cause uneven skin tone;

4. After being outdoors, you need to reapply sunscreen every 2 hours. It is recommended to use a sunscreen spray when reapplying sunscreen. This is because the water molecules in the sunscreen spray are more easily absorbed than sunscreen, thus avoiding ultraviolet rays from tanning the skin during the time difference between reapplication.
