III. Precautions: Health Disparities

  1. Most textbook dermatologic condition images and descriptions are on caucasian skin
    1. Adelekun (2021) J Am Acad Dermatol 84(1): 194-6 [PubMed]
  2. Skin Cancers (Melanoma, basal cell and squamous cell cancers) are dianosed at later, more advanced stages in people of color
    1. Culp (2019) Prev Chronic Dis 16: E79 +PMID: 31228233 [PubMed]
  3. Formal dermatologic training is lacking in conditions that affect black skin
    1. Buster (2012) Dermatol Clin 30(1): 53-9 [PubMed]

IV. Approach: Common skin conditions

  1. See Skin Cancer in Skin of Color
  2. Postinflammatory Hyperpigmentation
    1. Presents at any age in more than 65% of people of color, irregular hyperpigmented patches in regions of prior skin lesions
  3. Acne
    1. Skin of Color is more susceptible to scarring, Keloids and Postinflammatory Hyperpigmentation
    2. Many skin and hair products (e.g. cocoa butter, olive oil) used more commonly in Skin of Color communities exacerbate acne
    3. Start acne Topical Medications at less irritating, lower concentrations and increase slowly to reduce Postinflammatory Hyperpigmentation
      1. Retin A 0.025% cream every other day (instead of 0.05% gel daily)
      2. Benzoyl Peroxide 2.5% (instead of 5-10%)
      3. Azelaic Acid (Azelex, Finacea) may be indicated if Postinflammatory Hyperpigmentation is already present
