Skin care is divided into morning skin care and night skin care. The correct night skin care can determine the skin condition of the next morning, and the correct morning skin care can often determine the naturalness and durability of a day's makeup.The correct order of skin care should be as follows: cleansing → toner (toner) → mask → essence → lotion → eye cream → sunscreen (morning).

Sunscreen first and then isolate, sunscreen first and then isolate! Sun protection is the last step in skin care! The best way to use BB cream is to use sunscreen first and then isolate it.Sunscreen really protects against ultraviolet rays. Even if you are sitting in an office, there will be ultraviolet rays entering the room through the window, so you need sunscreen 365 days a year.

When you go to the hospital for acne, the doctor will make you remember to apply sunscreen. Because ultraviolet rays can aggravate acne inflammation, you should wear sunscreen for acne. If you are worried that sunscreen will make your skin greasy, and you are afraid of acne, it is recommended to choose a sunscreen with a safer sunscreen system. Prevent acne from getting worse. At the same time, thoroughly clean it before going to bed, so you don't have to worry about sunscreen making you stuffy.

Acne should be streamlined by the steps like water cream essence, rather than streamlined sunscreen.

This is not necessarily true. We depend on the characteristics of the whitening product you use. For example, the main ingredient of the whitening product you use is non-photosensitive niacinamide, so you can use it during the day, but if the whitening effect is achieved through VC, I recommend using it at night, because VC is light-sensitive.Therefore, it is best to study the ingredients through which whitening products are used to achieve the whitening effect. Also, during the whitening period, if you insist on applying sunscreen during the day, it will not have a big impact during the day.

The shelf life of cosmetics is divided into opened and unopened. The three-year shelf life of skin care products and the five-year shelf life of color cosmetics are all in the case of unopened. Once the cosmetics are opened, whether you use them or not, they will be exposed to air and bacteria will enter, so the shelf life of the cosmetics will be greatly shortened. If you are worried that you will not be able to use it up in a year, then buy a small one when you buy it. For our skin, do not reuse expired skin care products.

No. Here we only refer to the forming sheet mask. Due to its sealing properties, the mask can isolate the skin of the face from the air. It prevents the water in the skin from evaporating, increases the endogenous hydration of the stratum corneum, softens the keratin of the skin, expands the pores, and makes the skin soft and smooth. However, if it is too frequent, the stratum corneum will become thinner and thinner, so that excessive hydration of the skin will cause the destruction of the epidermal barrier function.
