Proven Wrinkle-Smoothing Power

The Silk Serum provides the smoothing benefits of retinol and beyond, adding moisture back into the skin and even soothing irritation. To find the hero ingredient, the R&D team at the Tatcha Institute searched high and low, testing efficacy against retinols and known alternatives like bakuchiol. They found the best results with a highly effective duo of plant-based retinol alternatives: upcycled cranberry extract and sea fennel, which act on the same factors as retinol to support natural skin turnover and give the look of collagen-rich skin.

Our scientists tested this Retinol Alternative Duo on human skin cells in-vitro, alongside a stabilized retinol. Our Retinol Alternative Duo was proven to act as well as the stabilized retinol on the same biomarkers which help to reduce the appearance of wrinkles and to improve visible firmness.*

*based on in-vitro testing on biomarkers COL1A1, COL3A1, and ELN

Retinol Alternative Duo: A plant-based complex of cranberry extract and sea fennel that acts on the same factors as retinol to support collagen-depleted skin without the use of drying, irritating Vitamin A derivatives. Cranberry, a superfruit that contains amino acids, is known for exfoliation and providing a radiant complexion. To isolate the natural biopeptides in cranberries, residual seed and pulp are transformed through a process of cold-pressed, eco-extraction that helps reserve resources and ingredient potency. Sustainably harvested and certified organic, our sea fennel helps reduce roughness and soothes visibly irritated skin.

Silk Protein: A moisture-binding ingredient that helps smooth and plump the appearance of dry, fine lines.

Hadasei-3: Our proprietary complex of Akita rice, Uji green tea, and Okinawa algae. This trinity of timeless ingredients work in harmony to reveal healthy-looking skin. With essential amino acids, it supports the skin’s moisture-keeping factors for beautiful skin.
