Description

Acne-removing face-refreshing essence and preparation method thereof

Technical Field

The application relates to the field of cosmetics, in particular to acne-removing face-refreshing essence and a preparation method thereof.

Background

Pox is a common skin problem, medically known collectively as acne. Pox is a disease of the pilosebaceous gland caused by the combined action of multiple factors, and the causes are four in most: 1) Increased sebum secretion; 2) Follicular sebaceous gland duct hyperkeratosis; 3) The propagation quantity of the corynebacterium acnes in the pilosebaceous gland is increased; 4) Inflammation is caused by inflammation mediators and the like.

Acne is usually seen on the face, and usually occurs in non-inflammatory lesions, including blackheads, whiteheads, etc., and then develops into inflammatory lesions, such as superficial papules and pustules, or further develops into deep cysts and nodules, etc.

Acne not only brings strong discomfort to patients, but also has influence on the appearance of patients in the society with higher and higher appearance, and brings unnecessary anxiety and depression. Therefore, the requirement for removing acne is higher and higher.

Acne-removing products on the market generally contain a large amount of bactericidal, exfoliating ingredients, which, although effective in treating acne, can cause irritation to the application site. Therefore, improvement is yet to be achieved.
