Abstract

The invention relates to a skin topical composition with the efficacy of promoting wound healing and / or scar repair. The skin topical composition includes (A) concentrated birch sap, and (B) one or more of Sanguisorba root extract, Coptis root extract, Arnebia extract, allantoin, Salvia miltiorrhiza extract, astragalus extract, pearl powder and asiaticoside, wherein the concentrated birch sap hasa concentration multiple of about 1.2-6 times, preferably about 1.5-5 times, more preferably about 1.5-3 times.

Description

technical field [0001] The present invention relates to a composition for external use on the skin with the effect of promoting wound healing and / or scar repair, which comprises (A) concentrated birch sap, and (B) Burnet elm root extract, Coptis chinensis root extract, comfrey extract extract, allantoin, salvia miltiorrhiza extract, astragalus extract, pearl powder and asiaticoside, wherein the concentration ratio of the concentrated birch juice is about 1.2-6 times, preferably about 1.5 times -5 times, more preferably about 1.5-3 times. Background technique [0002] The damage caused by skin burning, scalding, trauma, etc. is one of the common skin diseases that endanger human health and life safety. The resulting skin wound results in a breakdown of the integrity of the skin epithelium and may be accompanied by disruption of the structure and function of the underlying normal tissue. During the wound healing process, there are often situations such as pain in the affecte...
