All Day All Year protects the skin by activating its self-defense mechanisms to keep it younger, longer. To develop All Day All Year, Sisley Laboratories have studied the environmental and endogenous factors to which we are exposed during our life. These factors, which are grouped under the scientific term of Esposome, include solar radiation, pollution, smoke, etc. They are responsible for 80% of skin aging. The complex and highly concentrated formula of All Day All Year protects the skin from the aggressions that age it prematurely and strengthens its defense power thanks to its two complementary shields, physical and biological.

The physical shield offers complete protection of the skin on the surface:

- against UVA and UVB rays throughout the day *, thanks to its encapsulated filters that do not penetrate the skin.

- against pollutants to limit their penetration into the epidermis.

In the heart of the skin, the biological shield stimulates its natural defenses:

- strengthening the skin barrier;

- activating the skin's self-defense * capabilities to limit the harmful effects of pollutants and UV rays;

 - carrying out an anti-aging action.

How to use: Apply as a protective top coat after daily treatments. Its texture moisturizes and nourishes the skin just enough to be used alone if desired. It can be used at any age to preserve one's beauty capital.
