Problems solved by technology

[0006] However, the effect of a single plant extract is limited. When compounding different plant extracts, it is necessary to study the appearance, smell and function of different extracts. However, when different extracts are compounded together, due to the composition The influence between, but the effect obtained is weaker than that of a single component

Abstract

The invention discloses Hesperethusa crenulata-lemon extract for preventing and controlling propionibacterium acnes and an application thereof. The extract is a compound prepared from Hesperethusa crenulata extract and lemon extract through mixing according to a certain ratio. The extract has effects of resisting propionibacterium acnes, diminishing inflammation, resisting ultraviolet and oxidation, removing free radicals and reducing skin damage. The Hesperethusa crenulata extract and lemon extract can produce a synergistic effect of resisting bacteria.

Description

technical field [0001] The invention belongs to the field of cosmetics, in particular to a neem-lemon extract for preventing and treating Propionibacterium acnes and its application. Background technique [0002] Propionibacterium acnes (P.acnes for short) is a non-moving rod-shaped brevibacterium-like prokaryotic microorganism, which mainly parasitizes on human skin and mucous membranes, and usually exists in hair follicles, eyelids, lacrimal ducts and conjunctival sacs Inside, this flora can grow and reproduce on the skin for a long time, so it is called the resident bacteria of the skin and is the main bacteria that causes acne. [0003] Skin care products are substances or mixtures that are applied to any part of the human body (skin, hair, nails, lips, mucous membranes, etc.) by smearing, spraying or other similar methods to achieve cleaning, removal of bad odors, skin care, beauty and grooming products . [0004] With the development of society, people's living stand...
