Types of acne
  • Comedonal (non-inflammatory) acne: local treatment with azelaic acid, salicylic acid, topical retinoids.
  • Mild papulo-pustular (inflammatory) acne: benzoyl peroxide or topical retinoids, topical antibiotics (such as erythromycin).
  • Moderate inflammatory acne: benzoyl peroxide or topical retinoids combined with oral antibiotics (tetracyclines).
  • Severe inflammatory acne, nodular acne, acne resistant to the above treatments: isotretinoin, or contraceptive pills with cyproterone for females with virilization.
Remember: always consult a dermatologist to know what is best for you.

Acne rosacea Rosacea (ro-ZAY-she-ah) sometimes called "Adult Acne" occurs in people of all ages, especially older women when they go through menopause. Two famous men with the affliction are W.C. Fields and former United States President Bill Clinton. The disorder is characterized by redness, pimples, and, in advanced stages, thickened skin. People who flush or blush easily are most at risk of developing rosacea.

Acne scars Severe acne often leaves small scars where the skin gets a "volcanic" shape. Acne scars are very hard (and expensive) to treat and it is unusual for the scars to be successfully removed completely. In those cases, scar treatment may be appropriate. The most commonly used forms of scar treatments are:
  • Dermabrasion. The top layer of the skin is removed to make the scar look less pitted. It makes the scar less visible but does not remove it completely. Multiple treatments may be necessary to get the desired results. This procedure is usually performed by a cosmetic surgeon.
  • Microdermabrasion is a newer technique that has a similar effect to traditional dermabrasion, but is less radical. While dermabrasion is a surgical procedure, microdermabrasion is performed by blasting tiny crystals at the skin. Many dermatologists and cosmetic surgeons offer this procedure.
  • Laser resurfacing. A laser is used to burn off the top layer of the skin. This procedure is commonly known by the brand names of the machines used to perform it, including SmoothBeam. Many dermatologists and cosmetic surgeons offer this procedure.
  • Punch excision. The scar is excised with a punch tool and the edges are sutured together. This procedure is usually performed by a cosmetic surgeon.
  • Chemical peels (also known as acid peels). A type of organic acid, most commonly glycolic, salicylic, or lactic, is applied to the skin so that a smoother layer can surface. Despite its unpleasant name, this procedure is painless if performed properly and requires no anaesthetic. Peels are typically performed several times over a period of weeks or months. The procedure can also be beneficial for active acne. Many dermatologists and cosmetologists offer this procedure, although the peels given by dermatologists are generally of a higher concentration and therefore potentially more effective.
  • Subcision. The scar is detached from deeper tissue, allowing a pool of blood to form under the scar which helps form a connective tissue under the scar, levelling it with the surface. This procedure is usually performed by a cosmetic surgeon.
  • Dermal filler. The scar is filled with an injectable dermal filler like Bio-AlcamidŽ
More severe scarring usually responds well to a series of chemical peels over three to four months. If a doctor advocates this type of treatment, the first peels will be 35 per cent glycolic acid peel and gradually work up to a 70 per cent peel. If it is treating severe breakouts in addition to the scars, he or she may choose a salicylic acid peel, which will help clear up acne while treating the scars. It will take three to four months on average to see results.
