We’re still tracking retailers for this one. In the meantime:
La Roche-Posay's flagship pigmentation serum — and the launch product for Melasyl, an L'Oréal-patented brightening molecule that took 18 years to develop. Melasyl works by intercepting precursors of melanin synthesis (DOPAchrome and DHICA) before they oxidize into surface pigment, addressing post-inflammatory hyperpigmentation, melasma, and post-acne marks at the source. Layered with 10% niacinamide for tone-evening, phenethyl resorcinol for additional tyrosinase inhibition, and Tinosorb M for daytime protection of the very pigment process the serum is targeting. La Roche-Posay's clinical work shows 85% of users see reduction in persistent dark spots after 8 weeks. At $50 for 30ml, premium-mid pricing, but the Melasyl story alone makes this competitive with brightening serums at twice the price.
