Abstract

The invention belongs to the field of cosmetics and particularly discloses acne-removing composition and an application thereof to cosmetics. The acne-removing composition is prepared from components in parts by mass as follows: 0.1-0.5 parts of a vitamin A palmitate active matter, 0.1-1 part of an azelaic acid active matter, 0.1-1 part of a salicylic acid active matter and 0.1-1 part of an Asiatic pennywort herb extract, wherein the vitamin A palmitate active matter, the azelaic acid active matter and the salicylic acid active matter adopt active matters prepared by coating vitamin A palmitate, azelaic acid and salicylic acid respectively. The skin care composition can well penetrate skin surface layers to be absorbed and enter deep layers; all the components are matched in a specific proportion, and multiple contained effect ingredients are blended and cooperate with one another, so that the composition can play comprehensive roles in stripping aged cutin, dredging pores, inhibiting bacteria, diminishing inflammations, controlling oil, promoting metabolism, clearing pigmentation caused by acne and has the excellent acne removal and skin care effect.

Description

technical field [0001] The invention belongs to the field of cosmetics, and in particular relates to an acne-removing composition and its application in cosmetics. Background technique [0002] Acne, also known as acne, is a chronic inflammatory skin disease that occurs in the hair follicles and sebaceous glands of the face, chest, and back. Its typical skin lesions are acne, papules, pus marks, nodules and cysts. The generation of comedo is closely related to major factors such as excessive sebum secretion, pilosebaceous duct blockage, bacterial infection and inflammatory response. Commonly, after entering puberty, the level of androgen in the human body, especially testosterone, increases rapidly, which promotes the development of sebaceous glands and produces a large amount of sebum; at the same time, abnormal keratinization of the pilosebaceous gland ducts causes duct blockage, sebum discharge obstacles, and the formation of keratin plugs; A variety of microorganisms, ...
