In order to resist sugar in an all-round way, a pair of powerful CP- decarboxylation carnosine and Collrepair were added to saccharin-resistant Huazhong. This component is similar to carnosine in structure, and has the effects of antioxidation and anti-saccharification. Because it will not be recognized by enzymes in the body and lose its activity, it has better stability. Collrepair is a patent of BASF, the world's largest chemical company. It breaks the formed glycosylation end products and deglycosylates, which can help the skin regain its luster. Decarboxylation carnosine and Collrepair, an anti-sugar CP, can remove glycosylated proteins and improve the anti-glycosylation ability of skin by cutting off the opportunity of forming advanced glycosylation products.
Most whitening essences mainly use vitamin C as the main component of whitening, but because vitamin C is unstable and easy to oxidize, derivatives of vitamin C appear. In terms of stability, esterified vitamin C >；; Vitamin c glucoside > vitamin c salt > prototype vitamin c, but prototype vitamin c is still the strongest in terms of whitening and antioxidant effects. "Precursor of vitamin C" actually refers to vitamin C glucoside and vitamin C salt. Because of the strong acidity of vitamin C, it is best not to use it with high-concentration fruit acid, salicylic acid or A-acid products to avoid excessive stimulation. However, the combination of vitamin C and fruit acid with a concentration of about 4%~8% is beneficial to the absorption of vitamin C.
