Editor's Take
Kiehl's proprietary Melasyl™ molecule leads a liquid-crystal delivery system designed to intercept pigment precursors, backed by broad-spectrum chemical filters and Niacinamide.
Four-pillar formula scores
- Efficacy: 8.4 / 10
- Modern Tech: 8.2 / 10
- Clean Beauty: 6.3 / 10
- Sustainability: 5.0 / 10
The Verdict
This is a highly advanced sunscreen that doubles as a pigment-regulation treatment, anchored by L'Oreal's Melasyl™ technology and a liquid-crystal emulsion base engineered for active penetration. The efficacy is strong , it delivers both UV protection and targeted tone correction through a multi-pathway approach. The clean score is moderate due to the chemical filter load (Avobenzone, Octocrylene, Homosalate, Octisalate) and synthetic polymers in the base, which may trigger sensitivity in some users and limit alignment with stricter natural frameworks. Worth it if you're chasing a treatment-grade sunscreen with proprietary pigment science and can tolerate chemical filters.
