How to store the essence after opening

If essence is not used for a long time, it is best to refrigerate it. Essences that usually contain active ingredients such as vitamin C and its derivatives that are easily oxidized and degraded need to be refrigerated in a refrigerator at 5℃~10℃. The purpose of storing in the refrigerator is to prolong its activity and freshness, so that the skin care products can be maintained at the quality when they were first purchased. However, even if refrigerated, it should be used as soon as possible.

Can the serum be refrigerated?

1. Of course you can, but there is a precaution you should pay attention to: put toners, lotions, facial masks and high-protein skin care products in the refrigerator. This is one of the ways to protect skin care products. However, once skin care products have been refrigerated, they must always stay in the refrigerator. Otherwise the effect will be discounted.

2. It is a misunderstanding to put cosmetics in the refrigerator. Unless you use a special refrigerator for cosmetics. And not all cosmetics are suitable for storage in the refrigerator.

(1) Skin care products: Skin care products can be divided into cleansing (facial cleansers, cleansing creams), moisturizing (day and night creams), and skin care (facial masks, essences). Generally speaking, as long as they are kept in a cool place, the quality of the products can be ensured.

(2) Toners can be put back into their original packaging and placed on the bottom shelf of the refrigerator. Do not place them directly next to the refrigerator door because the exchange of hot and cold air during the opening and closing of the door can easily cause the product to deteriorate.

(3) Before storing cream-based skin care products, wipe the bottle mouth and cap with alcohol-based lotion or 75% diluted alcohol, tighten them, and then return them to the original packaging and store them in a cool place (no need to put them back in the refrigerator). Through such treatment, not only the quality of the product can be maintained, but also some residual bacteria can be killed.

(4) Skin care products that are not in use should be placed in a ventilated and cool place, or in a dry drawer. They should not be exposed to direct sunlight or placed in the bathroom. It is a wrong practice to put skin care products in the refrigerator. Too low a temperature is not only completely unhealthy for the skin care products, but the temperature difference between the inside and outside of the refrigerator, in and out, will cause the skin care products to deteriorate prematurely.
