An essential protective shield that activates the skin's daily self-defence, ensuring stronger, younger-looking skin for longer.

All Day All Year is an essential protective skincare product that should be used every day, all year round, to prevent skin damage. This smart moisturiser protects the skin from aggressors that cause premature ageing and enhance the skin's self-defence power.

When developing All Day All Year, Sisley's Laboratories studied the internal and environmental factors which have a detrimental effect on your skin throughout our lives. These factors are collectively known as the 'exposome' and are responsible for 80% of skin ageing. The exposome is made up of: UVA & UVB rays, blue light, pollution, cigarette smoke.

The complex and highly concentrated formula instantly protects the skin thanks to two complementary shields: the physical shield and biological shield.

On the surface of the skin, the physical shield provides comprehensive protection against harmful UV rays with the help of encapsulated UV filters and marshmallow polysaccharides, which prevent harmful pollutants from adhering and penetrating the skin.

Within the skin, the biological shield stimulates its natural self-defence capabilities by strengthening the skin barrier function, limiting the harmful results that occur when pollutants and rays are allowed to disperse within the skin, whilst providing an anti-ageing action.
