Hormonal changes that occur during puberty may cause acne.

Home Remedies for Acne

  • Cosmetics: Don’t be afraid to hide blemishes with flesh-tinted cover-ups or even foundation, as long as it is water-based (which makes it noncomedogenic). There are many quality products available.
  • Facials: While not absolutely essential, steaming and “deep-cleaning” pores is useful, both alone and in addition to medical treatment, especially for people with “whiteheads” or “blackheads.” Having these pores unclogged by a professional also reduces the temptation to do it oneself.
  • Pore strips: Pharmacies now carry, under a variety of brand names, strips which one applies to the nose, forehead, chin, etc., to “pull out” oil from pores. These are, in effect, a do-it-yourself facial. They are inexpensive, safe, and work reasonably well if used properly.
  • Toothpaste: One popular home remedy is to put toothpaste on zits. There is no medical basis for this. The same applies to vinegar.
