Abstract

The invention discloses a skin care film. The film is prepared from the following raw materials in parts by weight: 10 to 20 parts of vinyl modified hyperbranched polylysine, 0.1 to 0.3 part of strontium acetylacetonate hydrate, 2 to 4 parts of isopulegol, 3 to 5 parts of glycidyl ether-terminated allyl alcohol random polyether, 5 to 10 parts of ionized imidazolium salt-based polycarbonate-based polyester polycondensate, 1 to 3 parts of hyaluronic acid and 0.02 to 0.05 part of an initiator. The invention further discloses a preparation method of the skin care film. The skin care film disclosedby the invention is good in biocompatibility, sufficient in strength, good in air permeability and remarkable in skin care effect, can effectively prevent wound infection, accelerate wound healing, promote skin growth and reduce scars, and further has multiple functions of whitening, resisting skin aging and the like.

Description

Technical field [0001] The invention relates to the technical field of preparation of care materials, in particular to a skin care film and a preparation method thereof. Background technique [0002] In recent years, with increasing pressure from life and work, aging and increasing environmental problems, more and more people, especially modern women who love beauty, have been trapped by skin aging, wrinkles and sagging The appearance, loss of elasticity and gloss. In order to change this situation, they pin their hopes on beauty skin care products, hoping that beauty skin care products can restore their youth and health, and make their skin more shiny, elastic and free of stains. As one of the many types of beauty and skin care products, skin care membranes have attracted widespread attention due to their hydrating, calming, whitening and wound healing effects. [0003] In daily life, in addition to normal aging of the skin, it is often accompanied by skin damage, such as burns ...
