Do I need to wear sunscreen on cloudy days?

You need to wear sunscreen when going out on a cloudy day. Although we can't see the sun on a cloudy day, ultraviolet rays are still there. Clouds have almost no shielding effect on UVA rays, so you need to apply sunscreen when going out on cloudy days. It’s just that the sun protection factor can be lowered slightly, probably around SPF20 or PA++.

In addition to sun protection on cloudy days, you should also pay attention to sun protection on rainy days, indoors, and in autumn and winter. It can be said that you should wear sunscreen no matter what the weather is, all year round.

How to use sunscreen correctly

1. Moisturize first, then protect yourself from the sun. Before applying sunscreen, clean your skin first, and then apply lotion, essence, and facial cream to fully replenish the skin with moisture and at the same time separate the sunscreen from the skin. Because sunscreen contains qualities that can irritate the skin, direct contact with the skin is not a good idea.

2. Apply in advance. Generally, sunscreen needs to be applied twenty minutes in advance so that the skin can absorb the active ingredients in it to achieve the sun protection effect. Therefore, you should apply sunscreen twenty minutes before going out.

3. Reapply frequently. The sun protection effect of sunscreen is limited, and it is easy to sweat in summer, and ultraviolet rays are particularly strong. Generally, you should reapply after two or three hours. Sunscreen spray is very convenient for reapplying sunscreen.

4. Remove makeup. Many people think that sunscreen does not require makeup removal, but they are completely wrong. Sunscreen can easily clog pores, and it will cause great harm to the skin if makeup is not removed, so you must remember to clean your skin well.
