Taurine
What is Taurine?
Taurine is a naturally occurring beta-amino sulfonic acid, chemically 2-aminoethanesulfonic acid, present in high levels in human tissues such as the brain, heart, and muscles. It differs from standard amino acids by having a sulfonic acid group rather than a carboxylic acid. In skincare products, taurine functions primarily as a humectant to bind and retain moisture, an antioxidant to neutralize oxidative damage, and a buffering agent to stabilize pH levels for formula integrity. Its small molecule size allows good skin penetration, aiding cellular hydration and resilience. Often incorporated into creams, serums, and eye treatments, it also supports fragrance profiles by masking odors, enhancing overall product performance and user experience without compromising stability.
