| Bio-pharmaceuticals | ⭐The inhibition of collagenase, the inhibition of elastase, the inhibition of metalloproteinase and the scavenger of oxygen free radicals by loquat leaf extract indicate that loquat leaf extract can be used as an important additive in skin anti-aging cosmetics; Loquat leaf extract shows inhibitory effect on phosphodiesterase, which can accelerate the hydrolysis of fats, and the amount of glycerol from hydrolyzed indicates that loquat leaf extract is a good slimming cosmetic product; The inhibition of uridase by loquat leaf extract and the inhibition of methionase (the former is to decompose uric acid to ammonia, the latter is to decompose methionine to hydrogen sulfide, both of which are prominent components of human odor) indicate that the use of loquat leaf extract in sweat-suppressing cosmetics and oral hygiene products can reduce odor; Loquat leaf extract has a strong inhibition of hyaluronidase and is expected to become a cosmetic additive for dry skin prevention; In addition, in epidermal cell culture, loquat leaf extract promotes the production of cerebral amides, which helps to improve the composition of skin sebum and plays an oil-reducing and softening effect. |
