Each pore on the skin is an opening to the follicle that is made up of a hair and a sebaceous gland. The face is an area of the body with a higher number of sebaceous (oil) glands. These glands in the face produce excess oil and clog the pores in the skin. This causes acne to develop on the face. Homeopathic acne treatment is a safe and gentle solution for all types of acne.
