What is Acne?
Pimples, spots, or medically termed acne, are very common affecting almost 85% of young adults. It is not a teenage only problem; we are seeing more and more adults in their 30’s and 40’s presenting with new acne.
Acne is the term given to the combination of oily skin, blackheads, whiteheads, red and yellow spots, lumps and cysts on the face, and sometimes chest, shoulders and back. When left untreated they can lead to scarring and pigmentation. It starts in the early teens and sometimes continues into adult life.
Acne severity can range from mild with few spots, blackheads, and whiteheads, to severe with large painful cysts and permanent scarring.

How Is Acne in Skin of Colour Different?
Although the basic pathology of acne is the same, the concerns and consequences are different. The spots look less red in dark skin, and they leave dark marks called post-inflammatory hyperpigmentation. For this group of people, the dark marks are the main complaint. Also picking the spots seems to be more common which leads to dark marks and scars.
