Skincare for deeper skin tones

Primary source

Skincare for deeper skin tones: care considerations for Fitzpatrick skin types IV–VI, where hyperpigmentation (melasma, PIH, post-inflammatory marks) is more common and more noticeable, and where sun protection must work against both UV and visible light. The strongest evidence comes from a 2026 human trial: 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). 1 ingredient has evidence for Skincare for deeper skin tones: Niacinamide.

The studies here are small and specific (Fitzpatrick IV–V groups, usually 20–216 people); the sunscreen evidence is sunscreen-product-level behaviour. Pigment responses vary. The melasma, acne-marks and dark-circles pages carry the subtype evidence.

Source wording

“Hyperpigmentation disorders are prevalent in individuals with skin of color and associated with considerable psychosocial impact … Four priority conditions: melasma, acquired dermal macular hyperpigmentation, post-inflammatory hyperpigmentation, and periorbital hyperpigmentation.” — Sarkar et al., Int J Dermatol 2026 (PMID 42283350).

    An Investigator-Blinded, Randomized Trial of a Broad-Spectrum Sunscreen Containing Sclareolide and Niacinamide for the Prevention of Post-inflammatory Hyperpigmentation in Skin of Color

    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).

  1. 1 Skin effect
    A randomized study to evaluate the efficacy and effectiveness of two sunscreen formulations on Indian skin types IV and V with pigmentation irregularities

    In 216 Indian adults with Fitzpatrick skin types IV-V and pigmentation irregularities, regular use of two commercial sunscreens over 12 weeks significantly improved the clinical density of pigmented spots, skin radiance and chromameter-measured pigmentation.
