Abstract

The invention belongs to the technical field of cosmetics, and particularly relates to a whitening and spot-fading mask and a preparation method thereof. The mask takes tricholoma matsutake extract, acacia farnesiana extract, pentapeptide, rehmannia extract and dipotassium glycyrrhizinate composite watercress extract as functional components, can effectively solve the problems of dark and gloomy skin, color spots and the like, and makes the skin moisturized and whiter; and meanwhile, a preservative composition consisting of pistachio extract, phellinus linteus extract and isoferulic acid is added into the mask disclosed by the invention. The preservative composition has a remarkable inhibition effect on various common contaminating bacteria in cosmetics, the effective components are all natural plant components, the skin sensitization is low, the pH capacity limit value is wide (3-9), and the shelf life of the mask is remarkably prolonged.

Description

technical field [0001] The invention belongs to the technical field of cosmetics. More specifically, it relates to a whitening facial mask and a preparation method thereof. Background technique [0002] At present, the research on whitening products tends more and more towards natural plant extracts without adverse reactions. Plant extracts have a significant role in improving blood circulation and improving skin permeability. Without destroying the normal metabolism of melanin, Accelerate the metabolic process of melanocytes, shorten the physiological cycle of melanin in cells, prevent excessive deposition of melanin and form spots, and make the skin truly healthy and fair from the inside out. [0003] Mask is a cosmetic for facial skin that integrates cleansing, skin care, nourishing and beautifying. When using a mask, the secretions, dander and dirt on the skin can be peeled off together with the mask; ② skin care and skin nourishing effect: the mask covers the surface ...
