All Day All Year

During the day, our skin uses all its energy to protect itself. All Day All Year is therefore the perfect day care, as it acts like a global shield that protects the skin and activates its own defenses* to keep skin looking younger for longer. To develop All Day All Year, SISLEY laboratories studied the environmental and endogenous factors to which we are exposed throughout our lives. These factors, collectively known by the scientific term exposome, include UV rays, environmental stress, smoking, etc. Together they are responsible for 80% of skin aging.

The complex and highly concentrated formula of All Day All Year protects the skin from external agents that cause premature aging and strengthens its defenses* thanks to two complementary protective shields. The physical shield provides comprehensive protection on the skin's surface:

• It protects all day long against UVA and UVB rays* thanks to encapsulated filters that do not penetrate the skin**/***.
  
• It protects against environmental stresses, so they are less likely to penetrate the skin***.
  

Inside the skin, the biological shield stimulates its natural defenses by:

• strengthening the skin barrier
  
• activating the skin's own defenses* to reduce the harmful effects of environmental aggressors*** and UV rays*
  
• providing an anti-aging effect
  

A global shield that instantly protects the skin on the surface, strengthening its resistance and stimulating its natural defenses*. The pleasant, delicately melting texture leaves a silky, non-shiny finish on the skin and allows for quick makeup application.

The glass bottle was designed to be recyclable. The pump can be removed and the glass bottle recycled separately. The skin's defenses are strengthened*. It is smoother, softer and more comfortable. Fine lines and wrinkles are reduced, the skin is firmer. It is more beautiful and radiant and looks younger longer.

**Over 99% of filters remain on the skin surface.
