Should I apply the primer before or after sunscreen?

Whether to apply sunscreen first or to isolate first is really an old question that has been around for thousands of years. People always ask: should I apply primer first or sunscreen first? Many people cannot distinguish between sun protection and isolation. Everyone thinks that sunscreen can only prevent ultraviolet rays, while isolation cream can also isolate dust and radiation. People who are worried want to use both, so what is the order of using sunscreen and isolation cream?

Should I apply the primer before or after sunscreen?

Isolation comes after sun protection, first sun protection, then isolation. Sunscreen is needed for daily skin care, mainly targeting ultraviolet rays, while isolation cream is mainly used to isolate makeup and dirt in the air, so it is used before makeup, that is, before foundation. Both are indispensable. Maybe many people will say that isolation cream contains sunscreen ingredients, so do we still need to apply it? In fact, if you are exposed to ultraviolet rays for a long time, using only isolation cream is not enough.

Isolation or sun protection first?

1. The working principle of sunscreen is to isolate the skin from ultraviolet rays, effectively preventing the production of melanin, and preventing tanning and sunburn. Isolation cream has the effect of isolating ultraviolet rays, and its essence is sun protection. Compared with ordinary sunscreens, isolation creams have purer ingredients, are easier to absorb, and can prevent dirty air and ultraviolet rays from damaging the skin.

2. Apply sunscreen first. Because sunscreen is always the last step of skin care and the first step of makeup. Sunscreen is not only needed in summer. All year round, good sun protection can not only prevent tanning, but also effectively delay aging. Sunscreen takes time to be absorbed and work, so it should be applied 20-30 minutes before going outdoors.

3. Apply primer afterwards. Primer is an important step to protect makeup and skin. It can modify uneven skin tone, cover pores, control oil and moisturize, making makeup more fitting. If you apply foundation without using a primer, the foundation will clog your pores and damage your skin, and it will also easily cause the foundation to fall off.

4. Many people don’t know how to use sunscreen and isolation cream. They just apply them randomly, using circles like applying lotion. Therefore, it is easy to cause uneven application and white marks. It is best to apply sunscreen and isolation cream by gently pressing them. This method not only makes the sunscreen and isolation evenly applied without leaving any traces, but also prevents the formation of mud.

5. Whether it is sunscreen or isolation cream, you must use enough to achieve their due effect. International regulations require that at least 2 ml be used for the entire face, which is about the size of a one-dollar coin when squeezed out. If you don't use enough, the sun protection value will not only drop a little bit, but the SPF50 sunscreen may not have the same sun protection value as SPF15, so be sure to remember to apply enough sunscreen.
