Abstract
Description
technical field
[0001] The present invention relates to a kind of DL-cysteine or its salt, especially relates to a kind of DL-cysteine or its salt in the preparation of moisturizing, whitening, freckle, anti-inflammatory, anti-acne, anti-wrinkle, anti-aging, anti-hair loss , hair growth, anti-dandruff cosmetics. Background technique
[0002] With the improvement of living standards, people have higher and higher requirements for the effect and safety of cosmetics. At present, skin moisturizing, whitening, freckle removal, anti-inflammatory, anti-acne, anti-wrinkle, anti-aging, anti-hair loss, hair growth, anti-dandruff There are many functional ingredients used in cosmetics. Most of these functional ingredients are chemically synthesized substances. Not obvious, or the cost is particularly high, or the preparation and use conditions are particularly harsh. Therefore, various cosmetic research institutions are working hard to find new natural and effective alternative i...
