Acne is caused because your pores are clogged and your skin’s natural oils cannot escape. When this oil is mixed with your cells, bacteria forms and the area swell up. The canal that carries your oil breaks down and a pimple is formed. Blackheads are pimples that have opened up. Your skin’s natural oil changes its structure when it is exposed to air. The soaps in this kit are designed to absorb excess oil, prevent and control acne. Tip: Don’t pick at your pimples or they will just get worse!
