The invention discloses a method for making and using a biological enzymatic exfoliating facial mask. The invention pretreats the raw material of the biological enzymatic mask, prepares keratinase, optimizes enzyme action conditions, combines keratinase with cotton linter material mask, and keratinase Cryopreservation and mask room temperature are achieved using a series of steps. The present invention makes full use of keratin-degrading bacteria—Stenophora maltophilia ( Microbacterium sp .TSMC‑99) is fermented to produce keratinase. The keratinase adsorbed on the mask catalyzes the degradation of part of the keratinized tissue of the skin, removes keratinized dandruff on the face, removes dead skin, moisturizes the face, makes the skin clear and bright, and plays a role Skin rejuvenation. Bio-enzymatic exfoliating mask is a non-toxic, non-polluting, non-side effect, high-safety bio-tech product. Moreover, the production conditions are mild, environmentally friendly, easy to operate, easy to promote, and low in cost. The technical indicators of the manufactured mask meet the specifications of the light industry standard "QB / T 2872‑2007 Mask".
