Sisley has launched Sensitive Skin Soothing Care, a preservative-free skincare product specifically designed for sensitive skin — marking a significant milestone for the cosmetics industry.
This innovation demonstrates that product safety can be achieved without conventional preservatives when several key factors come together:
- Sterile manufacturing conditions
- High-protection airless packaging
- Smart formulation strategies
In particular, the ingredient list reveals high levels of glycerin and the presence of butylene glycol — both known for their ability to reduce water activity, helping limit microbial growth and maintain product safety.
This launch highlights how formulation science and packaging technology can work together to enable greener, preservative-free cosmetics.
