Abstract

The invention provides a compound for dispelling freckles and eliminating fine lines, dark under-eye circles and baggy eyelids, and a preparation method of the compound, and belongs to the technical field of cosmetics. The compound comprises a siraitia grosvenorii alcohol derivative as shown in a formula (I), and a rose flower residue alcohol extract, wherein a preparation method of the siraitia grosvenorii alcohol derivative comprises the steps of oxidizing an o-hydroxyl structure of siraitia grosvenorii alcohol into aldehyde, then reducing an aldehyde group structure into hydroxyl, then performing condensation on the hydroxyl and a BOC-amino acid carboxyl group, and removing BOC so as to obtain the siraitia grosvenorii alcohol derivative as shown in the formula (I). The preparation method of the compound comprises the step of uniformly mixing the siraitia grosvenorii alcohol derivative as shown in the formula (I) with the rose flower residue extract so as to obtain the compound. Thesiraitia grosvenorii alcohol derivative disclosed by the invention can dispel freckles depositing on skin surface, remove fine lines and wrinkles on the skin surfaces and improve the dark under-eye circles and the baggy eyelids. According to the compound disclosed by the invention, rose flower residue alcohol is used, so that the bioactivity of the siraitia grosvenorii alcohol derivative can be reinforced, and the effects of the compound for dispelling the freckles and removing the fine lines, the dark under-eye circles and the baggy eyelids can be improved.

Description

technical field [0001] The invention belongs to the technical field of cosmetics, and in particular relates to a compound for removing freckles, fine lines, dark circles and bags under the eyes and a preparation method thereof. Background technique [0002] Skin aging is a complex process of skin physiological structure disorder and functional degeneration with aging. It is affected by internal and external factors at the same time, and generally manifests in two forms: natural aging and photoaging. Natural aging is mainly caused by endogenous factors such as genetics, and it gradually appears with the passage of time. It is mostly manifested in fine and shallow wrinkles, dry, loose and rough skin. Photoaging is caused by external environmental factors such as long-term ultraviolet radiation. The clinical characteristic changes include thick and deep wrinkles, decreased elasticity, and spot-like pigmentation. Collagen is one of the most basic components of the extracellular...
