The invention provides a preparation method of a
probiotic and aloe
mask, which is characterized by preparing a
fermentation stock solution from
aloe vera raw juice, glucose and water according to certain proportions and adding probiotics for performing co-
fermentation. By setting different temperature gradients and pH gradients, after
viable count, optimal
fermentation conditions are determined; an aloe and
probiotic fermentation solution is adopted to carry out an antibacterial test so as to determine an
antibacterial effect, such as
propionibacterium acnes; and meanwhile, by determining an
antioxidant index, the
antioxidant ability of the aloe and
probiotic fermentation solution is determined, such as determination of
DPPH radical
scavenging ability, determination of iron
ion chelating ability and determination of total reducing force. According to the product, the aloe and probiotic fermentation solution is mixed with cosmetic auxiliary materials in proportion so as to be processed into a pasty
mask, and after sensory index testing,
skin irritation testing and trial effect testing, the safety and functionality of the product are determined, so that the aims of
skin protection and health care are achieved.
