Problems solved by technology

Kojic acid has high stability. It can chelate copper ions, reduce tyrosinase activity, and have obvious freckle removal effect. However, long-term use of kojic acid may lead to cytotoxicity and skin lesions.
Arbutin is considered as a whitening and freckle-removing agent with very low side effects, but it is highly photosensitive. A large amount of sunscreen is often added to the product, which is likely to burden the skin and accelerate skin aging
The target of the above products is single, the freckle removal effect is not obvious, and the side effects are relatively large. These defects have caused certain adverse effects on their wide application in the whitening and freckle removal market.

Description

technical field [0001] The invention belongs to the technical field of daily cosmetics, and in particular relates to a freckle-removing composition and an external preparation thereof. Background technique [0002] Melanin is an important factor in determining human skin color, and it is biosynthesized in melanosomes in melanocytes in the basal layer of the epidermis. Under normal physiological conditions, melanin in the skin can protect the skin from ultraviolet rays. When external aggression, hormonal imbalance, aging or other factors cause melanin synthesis and metabolism disorder, the melanin in the basal layer of the epidermis will easily increase, and the skin color of part or the whole body will deepen, causing freckles, chloasma, pregnancy spots, age spots, melanoma, etc. Pigmentation skin diseases affect people's appearance. The biosynthesis steps of melanin are: tyrosine present in melanocyte tissue is converted into dopa under the action of tyrosinase, and dopa ...
