There are a few types of acne:
A blackhead is a clogged follicle that remains open with a darkened surface.
A whitehead is a clogged follicle that remains closed, producing a white bump on the skin.
A pimple results from inflammation that has moved under the skin. A pimple can appear as a raised red bump or a raised red bump with a pus-filled top.
Cysts are infections that occur deep within the hair follicle. A cyst feels like a lump beneath the skin. Cysts can be large and painful.
A diagnoses of acne is made by a doctor based on the appearance of the skin. Additional tests are usually not necessary. In some cases, a cyst sample is examined to rule out a more serious staph infection.
Am I at Risk
Acne develops most frequently in teenagers because of hormonal changes, although acne can occur at any age. Females may develop acne in association with their menstrual period or birth control related hormonal changes. Other risk factors for acne include:
• Heredity. If your parents had acne, you have a higher risk of developing the skin condition.
• Skin Friction
• Oily products (cosmetics) applied to the skin
• Certain medications, such as steroids, birth control pills, or testosterone
• Significant sweating and humidity
