Daily application of SPF 15+ broad-spectrum sunscreen reduced clinical skin aging by 24% (OR 0.76, 95% CI 0.59–0.98) over 4.5 years compared with discretionary use in the Nambour randomized trial; microtopography confirmed significantly less photoaging progression; Australian NHMRC-funded with no industry involvement
Journal of Cosmetic Dermatology, 2025 · systematic-review
Updated review covering 67 articles: tinted sunscreen formulations containing iron oxides achieve visible light attenuation rates exceeding 93%, compared to <10% for non-tinted formulations; confirms iron oxides as the only practical approach to visible light photoprotection in topical sunscreens; recommends tinted sunscreens as standard of care for melasma and PIH-prone patients
Journal of the American Academy of Dermatology, 2015 · n=40 · rct
RCT (n=40) over 6 months: tinted sunscreen with iron oxides significantly reduced melasma relapse rate compared to non-tinted sunscreen with equivalent UV protection (p<0.05); both arms had identical UVA/UVB SPF — the only difference was visible light protection from iron oxides; establishes that UV protection alone is insufficient for melasma maintenance
