AI Technical Summary

Benefits of technology

The present invention provides a composition for preventing, ameliorating or treating acne symptoms using natural extracts with high antibacterial activity against the C. acnes strain, which causes acne. The composition includes a Sesamum indicum seed extract, a Quercus robur bark extract, and a Houttuynia cordata extract as active ingredients, as well as a Cirsium japonicum extract and / or a Thuja orientalis extract as additional active ingredients. The composition is formulated in a powder, gel, ointment, cream, liquid, or aerosol form, and can be used in various cosmetic products such as skincare, makeup, and body care. The natural extracts provide the advantage of being safe and effective without causing any side effects on the skin.

Problems solved by technology

For healthy skin, C. acnes plays a beneficial role in maintaining skin homeostasis and inhibiting the formation of colonies of other harmful bacteria, but it is known that acne is caused by imbalance of resident skin flora and action of a subtype of C. acnes, such as the acne-associated phylotype IA1, as an opportunistic pathogen due to the influence of a hyperseborrheic environment.

Most acne patients suffer from non-inflammatory acne, inflammatory papules, pustules, and the like, but severe inflammation may occur in some patients, and may leave scars.

The treatment of such acne is not easy, and acne bacteria exhibiting antibiotic resistance due to prescription of antibiotics for treatment have recently been reported, and it is thus becoming important to find a new antibacterial substance in order to overcome this problem.

According to this research trend, many studies have been made on medicinal plants, among various antibacterial resources that control acne bacteria, but the use of natural substances to control acne bacteria is still insufficient.
