The Silk Serum Wrinkle-Smoothing Retinol Alternative

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.*
