Acne

Acne is the most common skin condition in the United States, affecting up to 50 million Americans annually. 1

Acne usually begins in puberty and affects many adolescents and young adults. Approximately 85 percent of people between the ages of 12 and 24 experience at least minor acne. 2

Acne can occur at any stage of life and may continue into one’s 30s and 40s. 3-5 Acne occurring in adults is increasing, affecting up to 15 percent of women. 3-5

In 2013, the costs associated with the treatment and lost productivity among those who sought medical care for acne exceeded $1.2 billion. 6 More than 5.1 million people sought medical treatment for acne in 2013, primarily children and young adults. 6 The lost productivity among patients and caregivers due to acne was nearly $400 million. 6



Atopic dermatitis

One in 10 people will develop atopic dermatitis during their lifetime. 7 It affects up to 25 percent of children and 2 to 3 percent of adults. 8



An estimated 60 percent of people with this condition develop it in their first year of life, and 90 percent develop it before age 5. However, atopic dermatitis can begin during puberty or later. 8-9

In 2013, the costs associated with the treatment and lost productivity among those who sought medical care for atopic dermatitis was $442 million. 6 The total medical cost of treating atopic dermatitis was $314 million, for an average of $101.42 per treated patient. 6 The lost productivity among patients and caregivers due to atopic dermatitis was $128 million. 6



Hair loss

The most common cause of hair loss is hereditary thinning or baldness, also known as androgenetic alopecia. 10 This condition affects an estimated 80 million Americans — 50 million men and 30 million women. 11



Other Potential causes of hair loss, some of which are temporary, include: Excessive or improper use of styling products such as perms, dyes, gels, relaxers or sprays, which can cause weathering or hair breakage. Hairstyles that pull on the hair, like ponytails and braids. Shampooing, combing or brushing hair too much or too hard Hair pulling, which may be a sign of a disorder called trichotillomania. A variety of diseases, including thyroid disease and lupus. Childbirth, major surgery, high fever or severe infection, stress, or even the flu. Inadequate protein or iron in the diet, or eating disorders such as anorexia and bulimia. Certain prescription drugs, including blood thinners, high-dose vitamin A, and medicines for arthritis, depression, gout, heart problems and high blood pressure. Use of birth control pills (usually in women with an inherited tendency for hair thinning). Hormonal imbalances, especially in women. Ringworm of the scalp, a contagious fungal infection most common in children. Some cancer treatments, such as radiation therapy and chemotherapy. Alopecia areata, a type of hair loss that can affect all ages and causes hair to fall out in round patches. 12



Psoriasis

Approximately 7.5 million people in the United States have psoriasis. 13

Psoriasis occurs in all age groups but is primarily seen in adults, with the highest proportion between ages 45 and 64. 6

Approximately 25-30 percent of people with psoriasis experience joint inflammation that produces symptoms of arthritis. This condition is called psoriatic arthritis. 14-16

Approximately 80 percent of those affected with psoriasis have mild to moderate disease, while 20 percent have moderate to severe psoriasis affecting more than 5 percent of the body surface area. 13

The most common form of psoriasis, affecting about 80 to 90 percent of psoriasis patients, is plaque psoriasis. It is characterized by patches of raised, reddish skin covered with silvery-white scale. 13

In 2013, the total direct cost of treatment associated with psoriasis was estimated to be between $51.7 billion and $63.2 billion.6

Rosacea

Rosacea is a common skin disease that affects 16 million Americans. 17-19

While people of all ages and races can develop rosacea, it is most common in the following groups: People between age 30 and 60. 20 Individuals with fair skin, blond hair and blue eyes. 20-21 Women, especially during menopause. 20 Those with a family history of rosacea. 21

In 2013, the costs associated with the treatment and lost productivity among those who sought medical care for rosacea was $243 million. 6 More than 1.6 million people sought treatment for rosacea in 2013. 6 The total medical cost of treating rosacea was $165 million, for an average of $102.26 per treated patient. 6 The lost productivity among patients and caregivers due to rosacea was $78 million. 6



Skin cancer

Skin cancer is the most common cancer in the United States. 22-23

It is estimated that more than 9,500 people in the U.S. are diagnosed with skin cancer every day. 24-26

The majority of diagnosed skin cancers are NMSCs. Research estimates that NSMC affects more than 3 million Americans a year. 6, 24

The overall incidence of BCC increased by 145 percent between 1976-1984 and 2000-2010, and the overall incidence of SCC increased 263 percent over that same period. 27 Women had the greatest increase in incidence rates for both types of NMSC. 27 NMSC incidence rates are increasing in people younger than 40. 27

More than 1 million Americans are living with melanoma. 28

It is estimated that 192,310 new cases of melanoma, 95,830 noninvasive (in situ) and 96,480 invasive, will be diagnosed in the U.S. in 2019. 25-26 Invasive melanoma is projected to be the fifth most common cancer for both men (57,220 cases) and women (39,260 cases) in 2019. 25-26

Melanoma rates in the United States doubled from 1982 to 2011 and have continued to increase. 23, 26

Caucasians and men older than 50 have an increased risk of developing melanoma compared to the general population. 25-26

Melanoma is the second most common form of cancer in females age 15-29. 29 Melanoma incidence is increasing faster in females age 15-29 than in males of the same age group. 30

Skin cancer can affect anyone, regardless of skin color. Skin cancer in patients with skin of color is often diagnosed in its later stages, when it’s more difficult to treat. 31 Research has shown that patients with skin of color are less likely than Caucasian patients to survive melanoma. 32 People with skin of color are prone to skin cancer in areas that aren’t commonly exposed to the sun, like the palms of the hands, the soles of the feet, the groin and the inside of the mouth. They also may develop melanoma under their nails. 31

Nearly 20 Americans die from melanoma every day. In 2019, it is estimated that 7,230 deaths will be attributed to melanoma — 4,740 men and 2,490 women. 25-26

The five-year survival rate for people whose melanoma is detected and treated before it spreads to the lymph nodes is 98 percent. 25-26

The five-year survival rate for melanoma that spreads to nearby lymph nodes is 64 percent. The five-year survival rate for melanoma that spreads to distant lymph nodes and other organs is 23 percent. 25-26, 30

The annual cost of treating skin cancers in the U.S. is estimated at $8.1 billion — about $4.8 billion for NMSC and $3.3 billion for melanoma.22
