What Is Taurine?

Taurine is a powerful amino acid found naturally in skin that works to energise cells whilst promoting cell turnover. Research indicates topical application may help soften the look of visible signs of ageing by supporting cell turnover and reducing the impact of environmental aggressors. As a foundational element of proteins with antioxidant properties, taurine neutralises free radical damage.

It provides moisture whilst improving barrier function, preventing collagen breakdown, and maintaining skin firmness. Taurine neutralises free radicals, reduces fine lines and wrinkles, and promotes healthy cell turnover.
