types of acne

what is acne?

Acne is the appearance of blackheads, spots and pustules on the face, back and chest. Contrary to popular belief, it is not just teenagers who have acne. It affects 25% of all adult men and 50% of adult women at some time. No matter how severe acne is, it affects different people in different ways and many people with acne suffer from insecurities and depression.

acne vulgaris

Blackheads -- are caused by partially blocked pores. The "black" appearance of them is not caused by dirt, but by the melanin pigment from the dead skin cells.

Whiteheads -- are caused by completely blocked pores. The white appearance of them is caused by the bacteria inside the blocked pore turning the sebum to "free fatty acid".

Papules -- are small, red, tender bumps or spots.

Pustules -- are larger, red and inflamed pus-filled spots.

Nodules -- are large hard bumps under the skin's surface.

Cysts -- are similar to nodules, but can be deeply inflamed and infected.

acne roseaca

Acne roseaca is similar to acne vulgaris (oily skin, spots, pustules), but people with acne roseaca also experience skin flushing and a general redness of the area. These flushes can be set off by certain foods, such as spicy food and alcohol. People with acne roseaca rarely have blackheads (comedones).
