INTRODUCTION
The demographics of the United states are evolving with a large increase in racial and ethnic diversity driven by international migration of Hispanic, African, and Asian populations leading to a minority-majority shift in ~2050 towards persons of color (Fitzpatrick III, IV, V, and VI).1 Specifically, the Hispanic population is projected to be among the fastest growing population in the US, projected to increase from 55 million in 2014 to 119 million in 2060, a change of +115%.1
Subjects with skin of color are heterogeneous with multiple shades and tones and different reactions to intrinsic and extrinsic aging factors due to structural and physiologic differences.2,3 Skin of color individuals have fewer visible signs of aging (deep wrinkles, fine lines, rough surface texture, and sun spots). However, darker skin tones are more susceptible to certain skin conditions including post-inflammatory hyperpigmentation (may occur after acne, eczema, injury, laceration, melasma, post-inflammatory hypopigmentation, pityriasis alba (round, light patches covered with fine scales), dry or “ashy†skin, dermatosis papulosa nigra, and/or greater risk of keloid development.2,3 The incidence of skin cancer among US Hispanics has also increased 1.3% annually from 1992 to 2008.4
Photodamage is characterized histologically by degeneration of the connective tissue and abnormalities in keratinocytes and melanocytes. Clinically, it manifests primarily with wrinkles, dyschromia, texture changes, and, in more severe cases skin cancer.5 Formulations containing broad spectrum sunscreens against both UVA and UVB play an essential role in the prevention of photodamage and UV-induced skin cancers.6,7,8 However, the majority of clinical research on photoprotection has been conducted on subjects with Fitzpatrick types I to III skin and have reported improvements in signs associated with skin aging and texture.9,10 Verschoore et al was the first to conduct a short-term
