For reasons no one completely understands, follicles, often called pores, sometimes get blocked. Sebum (oil) which normally drains to the surface gets blocked and bacteria begins to grow. Both whiteheads and blackheads start out as a microcomedone. Microcomedones become non-inflamed skin blemishes called comedones--either a whitehead or a blackhead:

A blackhead or whitehead can release its contents to the surface and heal. Or, the follicle wall can rupture and inflammatory acne can ensue. This rupture can be caused by random occurrence or by picking or touching the skin. This is why it is important to leave acne prone skin relatively untouched.

Skin care is extremely important with any type of acne. Dermal Skin and Laser Centre carry a few lines of medical grade acne skin care products.

• Benzoyle Peroxide: Destroys acnes and may also reduce oil production.
• Salicylic Acid: Helps break down blackheads and whiteheads and also helps cut down shedding of cells lining the hair follicles. Salicylic Acid works by loosening clogged pores which prevents pimples from forming in the first place.
• Antibacterial: These soaps and cleansers kill the bacteria that contribute to acne.
  
  
• Alpha-Hydroxy Acids: This product is usually found combined with other acne fighting substances. It comes from acids naturally found in fruit. It does NOT kill the bacteria, but helps to remove the dead skin cells that clog up the pores.
