Blackheads are a very common skin condition that mostly affects your face, neck, back and chest. There are a variety of causes, including too much oil on your skin and hair follicle irritation. Blackheads commonly affect adolescents, but they can occur at any age.
Blackheads typically affect teenagers and young adults undergoing hormonal changes. However, many adults continue to have acne into their 20s, 30s and beyond. Some even develop blackheads for the first time as adults.
How common is this condition?
Blackheads are very common. Some researchers suggest that blackheads affect nearly everyone during their lives. They’re most common among adolescents, but up to 10% to 20% of adults have blackheads too.
How do blackheads affect my body?
Your face (especially your nose and chin, sometimes your cheeks), neck, back and chest are most likely to develop blackheads. However, oil (sebaceous) glands are all over your body.
They release an oily lubricant called sebum that helps keep your skin and hair hydrated and shiny. As a result, though it isn’t common, blackheads sometimes appear on your butt, thighs, ears and armpits.
