The sugar-resistant small white bottle is an upgraded version of the original photosensitive small white bottle. In terms of composition, on the basis of the original 99.7% purity nicotinamide combined with Sepiwhite whitening factor [China invention patent number: ZL200480019861.9], inositol and active VC(AA2G), four-step full-channel black suppression was completed.
Glucocorticoid, a new anti-sugar component, is added. The combination of glucocorticoid and nicotinamide can realize triple full-link anti-sugar. Nicotinamide can resist the invasion of sugar, and glucocorticoid can protect protein from saccharification, which is helpful to accelerate the decomposition of advanced glycation end products (AGEs) in the skin.
