Biochemical Mechanism & Pharmacology
Alpha-Arbutin and Tranexamic Acid (Topical) operate via distinct physiological mechanisms without reactive cross-oxidation or competing receptor antagonisms. They can be safely integrated into the same routine when sequenced properly from thinnest to thickest consistency.
Apply Alpha-Arbutin (pH 4.5–6.5, Viscosity Tier 2) first. Wait 1–2 minutes for absorption, then follow with Tranexamic Acid (Topical).
