Throughout the day, the skin expends energy for its protection. Sisley's All Day All Year, an ideal daytime defense, works as a comprehensive barrier, enhancing the skin’s natural defense mechanisms to preserve its youthful appearance over time. The creation of this product involved Sisley Laboratories meticulously examining the various environmental and internal factors we encounter throughout our lives. Known as the exposome, these include elements like UV exposure, pollution, and smoking, which contribute to 80% of skin aging. All Day All Year features a potent and sophisticated formulation that guards against premature aging causes while boosting skin’s natural defenses through its dual layers: physical and biological shields. This broad protective barrier provides immediate surface protection, enhances resilience, and invigorates the skin's intrinsic strength. Its lightweight, creamy feel ensures a smooth application without shine, allowing for easy makeup application afterward. The packaging is designed for recyclability, with a detachable pump and eco-friendly glass that adheres to recycling standards. *In vitro testing indicates that over 99% of filters remain on the surface. Ex-vivo assessments show that the biological shield at the core of the formula enhances the skin’s inherent defenses, fortifies its natural barrier, and activates self-protective mechanisms against pollution and UV damage, while also delivering anti-aging benefits. With this, the skin’s defense becomes more robust, feeling softer and smoother. Fine lines and wrinkles diminish, leading to a firmer, more luminous complexion that maintains a youthful look for an extended period.
