Acne (pimples & zits)
- Acne is a very common skin problem, affecting about 40 million to 50 million Americans.

- Acne usually appears on the face, chest and back.
- By the mid-teens, more than 40% of kids have acne or scars from acne that need to be treated by a dermatologist.
- In 2004, people spent $2.2 billion to treat acne.
- More than 1 million new cases of skin cancer will be diagnosed in the U.S. this year.
- 1 out of 5 Americans (17%) will have skin cancer at some point in their life.
- Melanoma is the most serious kind of skin cancer, and one in 58 people will get melanoma at some time during their life.
- Melanoma is the most common kind of cancer for young adults who are 25-29 years old. It is the second most common kind of cancer for teens and young adults who are 15-29 years old.

Hair & Nails
- It’s normal to lose 50 to 100 hairs a day but anyone who notices thinning hair should see a dermatologist.
