Should I wash my skin before exercising with sunscreen?

Do you need to clean before touching the sunscreen before exercising** Mainly to see whether it is indoor or outdoor, if it is indoor exercise, it is best to wash off the sunscreen before exercising, although sunscreen isolates the damage of ultraviolet rays, but after all, it belongs to cosmetics, and cosmetics contain most chemical ingredients, especially during exercise, it is not suitable to rub, the pores will open during exercise, and the makeup on the face is easy to enter the pores, thus clogging the pores, and produce adverse reactions, which will produce whiteheads and acne, So when exercising, try to let ** be able to breathe freely, and don't rub any makeup to avoid clogged pores. But if it is an outdoor exercise, sunscreen must be applied, and there is no need to wash it before exercising, otherwise strong light and ultraviolet rays will cause great damage to the skin, easy to produce sunspots, sunburn, tanning, and even cause various skin problems.

Proper ways to use sunscreen:

1. Before using sunscreen, clean the skin before using it, and then apply lotion. If you have dry skin, you can apply a layer of lotion after lotion, and then use sunscreen. If you want to be exposed to sunlight for a long time, it is recommended to use a product with SPF 30 PA+ or higher, and if you are staying in the office facing the computer for a long time, then only SPF15 PA+ product is enough.

2. Sunscreen must be applied evenly, don't only remember your face, but forget your neck, arms and other parts. Otherwise, you will find that everything is black except for your face, and it is not good-looking! Don't forget behind your ears either!

3. Sunscreen should be applied about 20 minutes before going out, because sunscreen does not have the effect of sunscreen on the application, and it needs to give the skin time to absorb. And sunscreen doesn't last all day, so reapply it when you're sweating a lot or after a few hours of sunscreen.

4. Don't mix and match brands of sunscreen. In order to thoroughly protect themselves from the sun and protect their fair and delicate skin, many people use several brands of sunscreen to pursue better sunscreen effects. This is not the right practice, as mixing multiple brands of sunscreen together will not only exclude each other, but may also cause allergies.

In fact, many excellent sunscreens have good sun protection effects, and you don't need to use so many products.

5. Use makeup removers. Don't think that you only need to use cleansing oil if you wear heavy makeup, but you still need to remove makeup when you use sunscreen and base cream to prevent sunscreen residue on your skin from clogging pores and causing various problems such as rough skin or acne.

No, you don't. Just remove it before you take a shower.

No, just use it after your base makeup.

Sunscreen refers to cosmetics that are added with sunscreens that can block or absorb ultraviolet rays to prevent skin from tanning and sunburning. According to the principle of sunscreen, sunscreen can be divided into physical sunscreen and chemical sunscreen.

Sunscreen needs to choose products with different SPF or PA values according to the specific object to achieve the purpose of sun protection.

The main difference between sunscreen lotion and sunscreen is the physical properties, the general water content of the cream is about 60%, which looks relatively "thick" and paste-like; The emulsion, with a water content of more than 70%, looks relatively thin and fluid. In general, lotions are cooler than creams because of the higher water content, but formulators can still adjust the "oiliness" of creams with different oily ingredients and thickeners. Therefore, it is still necessary to look at the product itself.

Sunscreens can be divided into physical sunscreens, chemical sunscreens. However, chemical sunscreens are better in terms of skin feel and visual effect, while people who are more sensitive or extremely dry are more suitable for physical sunscreen.

Physical sunscreen.

Sunscreen particles are used to form a protective layer on the surface of the skin, reflecting light waves from ultraviolet rays that can cause damage to the skin, so as to protect the skin. The particles of physical sunscreen generally stay on the surface of the skin and are not absorbed by the skin, so the burden on the skin is relatively small, and it is not easy to cause skin sensitivity.

Chemical anti-stuffiness sunscreen.

By combining certain chemicals with cells, the part of UV rays that can be harmful to the skin is absorbed before the cells are damaged, so as to achieve sun protection.
