F-ACN formula is a target treatment for acne. Acne is a disorder of the hair follicle and sebaceous gland. It happens when the pores sometimes get blocked with dead skin cells. Sebum which normally drains to the surface gets blocked and bacteria such as P. acnes begins to grow and the pore becomes inflamed. Inflammation is what causes a pimple to look red and swollen. The sebum (oil): lubricate and protect skin & hair. Sebum production is triggered by DHT which is modulated by 5--reductase enzyme. Consequences of acne: Blemishes & pimple, low self-esteem, depression, dark spots on the skin, scars.
