How long is the shelf life of mandelic acid essence after opening

Normally, the shelf life of essence is three years, but after opening it is only one year and must be used up during this period. Mandelic acid can metabolize dead skin cells, purify pores and reduce dullness. Mandelic acid essence is suitable for skin with closed acne, skin that wants to accelerate whitening, and skin with thick stratum corneum that needs exfoliation.

How long can the essence be kept after opening?

The shelf life of essences from different brands after opening is different. The bottle usually has an opening date. If there is an "m" on it, it means the shelf life is in months. 1m means one month. It is recommended that essence products, whether they are press-type or functional, be used up within one year regardless of whether they are opened or not. The effect may not be good if used after one year.

Most essences come in small containers and are usually used up within a few months, and no more than a year at most. If left unused for a long time, they will easily deteriorate. Although some essence packaging boxes usually have a three-year shelf life, the best shelf life of the active ingredients contained in the essence is six months after leaving the factory.

Serums are usually stored in smaller containers than creams and lotions because they can be used up quickly in a short period of time. Essence is also one of the fastest-used products among many skin care products. As long as it is used up within the normal time, it will not expire. Essence should be avoided from contact with sunlight, otherwise it will be oxidized, thus destroying the essence ingredients. Whether it is an open-cap type or a dropper type essence, cross-contamination must be avoided.
