I led the U.S. Amazon storefront strategy for Centellian24, a Korean dermocosmetic brand backed by Dongkook Pharmaceutical's TECA technology since 1968. This project focused on translating decades of clinical heritage and a globally-sold hero ingredient into a storefront that builds instant trust with U.S. Amazon shoppers. Key contributions: * Ingredient-Led Storytelling: Positioned TECA 11,900ppm (Titrated Extract of Centella Asiatica) as the brand's signature differentiator, translating a clinical formulation into a clear, memorable hero claim. * Clinical Credibility Signaling: Surfaced dermatologist-tested badges (Sensitive Skin, Acne-Prone Skin, Non-Irritating) and the Dermatest Excellence Award directly into the storefront to build trust within seconds of landing. * Proof-Driven Layout: Structured before/after clinical results (8 types of dark spots, redness improvement) with study details to make efficacy claims credible rather than promotional. * Social Proof Integration: Wove customer testimonials including sensitive-skin and rosacea-specific results into the PDP to reinforce real-world efficacy alongside clinical data. * Heritage Positioning: Anchored the brand's "Since 1968" pharmaceutical legacy as a trust signal, distinguishing Centellian24 from newer, trend-driven competitors.
