There are various microorganisms on the skin. These microorganisms cause various skin diseases. Staphylococcus aureus, which causes purulent skin, includes Staphylococcus epidermis, Acne bacteria (Propionibacterium acnes), Oily skin infections (oval patirosporum bacteria, Pity ovale) These bacteria decompose sebum or sweat secreted on the skin and produce odors. In addition, the degradation products irritate and irritate the skin. In particular, acne bacteria (Propionibacterium acnes) breaks down sebum by using a fatty acid degrading enzyme lipase (lipase) to produce free fatty acids. These free fatty acids not only irritate the skin but also cause inflammatory lesions such as papules, pustules and nodules, which are red rashes found in acne.

Dermatophytes invade the stratum corneum of the hair and skin, causing superficial mycosis. The skin filaments that cause superficial mycosis include Microsporum, Trichophyton, and Epidermophyton, and fungi represent ringworm. Candida albicans causes cutaneous candidiasis and chronic mucosal candidiasis. These fungi represent superficial mycosis, in which the fungus parasitic in the keratinous tissue of the skin and multiplies and causes lesions. Another cause of granulomatous lesions in skin and subcutaneous tissue is Sporotrix schenckii.

In order to treat such acne, attempts have been made to have a therapeutic effect by smoothing the secretion of sebum through exfoliation of pores using salicylic acid or vitamin A derivatives, or by using benzoyl peroxide. Attempts have been made to cure through removal and strong antimicrobial action. However, salicylic acid preparations can cause skin redness, swelling or skin repellency, as well as poor therapeutic effects, while retinoic acid preparations have the effect of inhibiting hyperkeratosis, but contact dermatitis, erythema, skin drying and peeling may occur. In addition, benzoyl peroxide preparations have been reported to cause side effects such as allergic contact dermatitis, scarring and severe erythema.
In view of these problems, the present inventors have studied to develop cosmetics that are excellent in the prevention and treatment effect of acne and excellent in the safety of the skin even for a long time use. As a result, Magnolia obovata bark extract and Camellia sinensis leaf extract, grapefruit seed extract, ginger root extract, and Phellodendron amurense bark extract were used to combine the components of the extract. By confirming, the present invention was completed.
