Perceptions of Sun Protection, Skin Tone, Colorism, and Dermatologic Care Among South Asians in the USA.

South Asians (SAs) are among the fastest growing populations in the USA. Colorism - the system of inequality that views lighter skin as more advantageous in society - is prevalent in SA culture. This study evaluates motivations of sun protection use, attitudes of colorism, and skin lightening (SL) practices among SA Americans. Two-hundred-four participants recruited from online forums and ResearchMatch completed a questionnaire. Over half (111/204) reported use of sunscreen, of which 39.6% (44/111) reported daily or frequent use. Nearly half of respondents (98/204) believed that they are not at risk for skin cancer, with 37.7% (77/204) reporting minimal knowledge of skin cancers and only 4.9% (10/204) receiving a total body skin exam. One-third (65/204) reported being more concerned about prevention of tanning than skin cancer. In total, 38.2% (78/204) of respondents reported use of SL products, of which 33.3% (26/78) reported hydroquinone-based products and 26.9% (21/78) were unaware of the ingredients in their SL product. Only 16.7% (13/78) consulted a medical professional before using SL products. While many agreed that SA culture places high importance on light skin with regards to beauty standards (82.3%, 168/204), less noted that lighter skin is more beautiful (37.0%, 74/204). SL users more strongly agreed with colorism attitudes than non-users. Limitations include a small sample size with younger participants. Dermatologists must be mindful of the cultural motivations for skin tone preferences, sun protection habits, and SL behaviors and provide culturally relevant education on sunscreen, skin cancer, and risks of SL for the SA community.
