Acne is a common skin condition caused by the blockage of hair follicles by sebum (oil), dead skin cells, and bacteria. The blocked pores lead to the development of whiteheads, blackheads, inflammatory papules or nodules (red, tender bumps), pustules (pus filled bumps), and even cysts. Acne breakouts can occur at any age but are most common during the teenage years. Hormonal changes, certain medications, and the use of oily or greasy products are some factors that can contribute to breakouts. Acne breakouts most typically occur on the face, chest, back and shoulders. Numerous treatment options are available including but not limited to: over the counter products, prescription topical medications, prescription oral medications, photodynamic therapy, chemical peels, and laser therapy.
