Risk factors

Risk factors for acne include:

• Age. People of all ages can get acne, but it's most common in teenagers.
• Hormonal changes. Such changes are common during puberty or pregnancy.
• Family history. Genetics plays a role in acne. If both of your parents had acne, you're likely to develop it too.
• Greasy or oily substances. You may develop acne where your skin comes into contact with oil or oily lotions and creams.
• Friction or pressure on your skin. This can be caused by items such as telephones, cellphones, helmets, tight collars and backpacks.
