Evidence: In 20 people with Fitzpatrick skin types IV-V, a broad-spectrum sunscreen containing sclareolide and niacinamide significantly prevented experimentally induced post-inflammatory hyperpigmentation: in stripped, exposed zones the protected skin improved by +5.96 ITA degrees versus -9.88 in unprotected skin (net protection about 16 ITA degrees, p < 0.001).
