Blackheads can happen to anyone, no matter what your skin type.

Blackheads are caused by oil in your skin that gets caught and expands in the pores. Oxidizing from exposure to the air, the oil actually turns black.

Some other causes are…

Genetics
Hormones
Poor cleansing routine
Squeezing or picking of the skin
Excessive makeup and use of excessive oil based cosmetics
Dirt is also a major cause of blackheads. The dirt collected on the face and other parts of the body gives rise to bacteria development and results in blackheads. Some medications
Environmental pollution and humidity
Stress

Getting rid of them:

1. First, stop the problem before it starts. Use noncomedogenic, oil-free,water-based skin-care products. (Noncomedogenic means the products were laboratory tested and approved by the FDA not to clog pores and cause blackheads.)

2. If you change your skin-care routine and still get blackheads, speak to a dermatologist about getting a prescription for Retin-A, which is a strong exfoliant that opens pores, sloughs off dead skin and cleans out blackheads.

3. If all else fails, a dermatologic facial performed at a dermatologist's office involves a prescription-strength acid that gets rid of dead layers of skin and the use of surgical instruments to extract the blackheads.

Avoid trying to remove them by squeezing, pricking with a needle, pin or tweezers. Our facial skin is very delicate so that only makes the condition worse. Not only is it unhygienic but it also aggravates their spread.

I recommend heading to Dermalogica for one of their blackhead relief microZone treatments, they are only $50 and work wonders!
