The founder of Tatcha, Vicky Tsai, created the label after years of struggling with acute dermatitis - a result of a stressful, work-inflicted lifestyle. She was soon captivated by the Japanese philosophy of hinou dokon, which emphasises the symbiotic relationship between the mind and the skin. Inspired by this, all of the brand's formulas work in harmony with the body's natural balance. The Silk Firming Set, for example, offers a complete ritual for radiant, hydrates skin, with The Silk Serum offering a clinically proven retinol alternative and The Silk cream providing rich, weightless hydration. Both formulas utilise natural extracts, with the former featuring sea fennel and upcycled cranberry extract, while the latter uses rose extract and silk fibroin to retain moisture.
