Sources by topic
Hyperpigmentation & PIH
J Cutan Med Surg (2024) · 2024
Fetched abstract. Finds PIH disproportionately affects darker skin tones, 78% female, mean age 29. Full-text algorithms were not extracted in the research session.
J Dermatolog Treat (2021) · 2021
Fetched abstract. SPF30+ sunscreen recommended in almost every high-quality study; retinoids, hydroxy acids, and broad-spectrum sunscreen carry the greatest evidence support.
Am J Clin Dermatol (2022) · 2022
Fetched abstract. PIH is often more distressing than the acne itself in skin of colour; acne lesions improve weeks before PIH resolves.
J Drugs Dermatol (2026) · 2026
CAVEAT (verbatim from report): RSV is RELATIVE interest, not absolute volume, and does not prove commercial intent. Pigmentation and hyperpigmentation were the highest-interest terms, with a marked spike in early 2025; Ghana, Nigeria, and Mauritius frequently ranked highly.
Reddit r/Blackskincare · 2025-01
One fetched thread, not an African-consumer sample. Commenters report improvement took 'around three months' and marks took 'nearly a year' to nearly disappear.
Sunscreen & Visible Light
Int J Dermatol (2024) · 2024
Fetched abstract. Visible light is a significant and underrecognized contributor to hyperpigmentation, particularly relevant to darker phototypes.
Photodermatol Photoimmunol Photomed (2014) · 2014
CAVEAT (verbatim from report): this was melasma with concurrent hydroquinone — it does NOT directly prove the same outcome for untreated PIH or for any specific commercial product.
PubMed (2026) · 2026
97.3% of 37 tinted sunscreens did NOT list iron-oxide content as an active ingredient; only 9.6% of responding brands disclosed percentages.
