Acne is an inflammation of the skin that causes blackheads, whiteheads and painful red spots. Acne mainly affects the skin of the face, but it can also affect the chest, back and arms.
Acne mainly affects about 90% of adults and 20 to 30% of people in their 20s and 40s.
Compared to other skin conditions, most people who see a doctor are people with acne. The condition does not threaten a person’s life, but it can be distressing and cause psychological problems.
Acne is the most common skin condition that most people experience throughout their lives. Although this primarily affects adolescents who are affected by hormonal changes, many people still develop acne in adulthood.
It is more common in girls aged 14 to 17 years and in boys aged 16 to 19 years. Acne can be mild (occasional pimples), moderate (inflammatory papules), or severe (hard bumps and cysts). The scar may remain on the skin forever. Treatment also depends on the severity of the disease.
