SkinMedica Lytera 2.0 Pigment Correcting Serum
Multi-target brightening with hexapeptide, tranexamic acid, and niacinamide
이 치료에 대해
SkinMedica Lytera 2.0 is an advanced brightening serum with multi-target approach without hydroquinone.
■ Hexapeptide complex: suppresses tyrosinase at gene expression level ■ Hexylresorcinol: melanin reduction (breaks down existing pigment) ■ Tranexamic acid: blocks UV-induced melanin via plasmin inhibition ■ Niacinamide: melanosome transfer inhibition + ceramide synthesis ■ Kojic acid: alternative depigmentation pathway
Validated in 10 clinical studies across 200+ subjects in US, Thailand, and Japan.
작용 기전
Hexapeptide complex acts on TYR gene promoter to suppress tyrosinase mRNA transcription. Hexylresorcinol reduces/breaks down existing eumelanin. Tranexamic acid inhibits plasminogen→plasmin conversion, blocking UV→PGE2→MITF→tyrosinase cascade. Niacinamide attenuates PAR-2 signaling, inhibiting melanosome transfer 35-68%. Five mechanisms cover all stages of pigmentation.
