Facial cleanser, also known as facial cleanser, belongs to cleaning cosmetics.

It can be used to remove dirt from facial skin surface, keep skin fresh and comfortable, and help maintain normal physiological functions of skin. Usually as the first step of skin care.

Facial cleanser belongs to facial cleaning products. When cleaning the skin, the objects to be cleaned by facial cleanser are dirt from the body such as sebum, sweat and exfoliated cuticle cells, as well as dirt from the outside such as dust, various microorganisms and cosmetic residues.

These residual metabolites are unstable and will react with oxygen in the air or deposited molecules. When exposed to sunlight or bacteria exist on the skin, various physical, chemical and biochemical reactions will occur, forming some irritating substances that may harm the skin.

Matters needing attention and misunderstandings

(1) Points for attention in selecting sensitive muscles and problem skin.

For sensitive or fragile skin, it is necessary to consider the gentleness and safety of the product, and it is recommended to use a milder facial cleanser.

(2) Foam has nothing to do with the effect of facial cleanser.

The foam and fineness of facial cleanser are not directly related to the quality of facial cleanser. However, the rich and delicate foam is the key factor that many consumers choose to use repeatedly.

(3) Don't over-clean.

Lipids from sebaceous glands will recover in a certain time even if they are temporarily removed after cleaning, but lipids from stratum corneum need time to recover, and the moisture of skin is mainly maintained by NMF (natural moisturizing factor) contained in skin. Therefore, the skin should not be excessively cleaned to avoid excessive removal of cortical membrane and dissolution of NMF and intercellular lipids (ceramide and cholesterol).
