Will the patch mask expire? What is the shelf life of the patch mask?

Patch masks can usually be removed after about 15 minutes, and then the subsequent skin care steps can be carried out. So will patch masks expire? What is the shelf life of a sheet mask?

Do sheet masks expire?

Sheet masks expire. After a facial mask expires, the ingredients in it will change. Not only will it lose its original protection for the skin, but continued use may also cause skin allergies and some serious skin problems due to the change in its ingredients. So when buying facial masks, don’t stock up too much, otherwise the masks will easily expire. Don’t continue using expired facial masks. Don’t take risks on your skin just because you can’t bear to do so. It’s not worth it. Facial masks are daily skin care products. I would like to remind everyone to limit the number of masks you buy, otherwise they will expire if you don’t finish using them, and it would be a pity to throw them away directly.

What is the shelf life of a facial mask?

The shelf life of a facial mask depends on its texture. There are two types of facial masks for daily use: patch type and smear type. The shelf life of both is generally about three years. However, once a patch mask is opened, it must be used immediately and not left overnight. It is best to use up smear-type facial masks within six months.

The difference between sheet masks and smear masks

The difference is in form: most smear-type facial masks are packaged in cans like facial creams, and their texture is generally mud-like, while sheet-type facial masks are mostly in the form of paper sheets. The second is the method of use. The smear-type mask needs to be applied on the face by yourself, and be careful to avoid the area around the eyes and corners of the mouth. For the patch-type mask, you only need to stick the mask flat on the face.

The effects of facial masks

1. Skin cleansing effect: The mask has a deep cleansing effect on the skin. The mask is usually applied on the facial skin for about 20 minutes. When the mask is torn off, it can completely remove the skin's epidermal cells, deep-seated grease and dirt, residual makeup and other dirt that are usually difficult to wash off.

2. The role of nourishing the skin: In addition to some "nutrients" contained in the mask itself, the mask can also increase the temperature of the skin surface when used, thereby accelerating blood circulation, reducing moisture evaporation from the facial skin, softening the stratum corneum, expanding pores, and enhancing the facial skin's absorption of nutrients.

3. The effect of "tightening" the skin: Some functional masks can tighten the skin, shrink pores, reduce wrinkles and reduce skin sagging.

4. Special "therapeutic" effect: It is still a partially functional mask, in which some effective ingredients are added according to the corresponding therapeutic effects. It can be used to treat some facial skin problems, but it is best to use it correctly under the guidance of a dermatologist.
