ADuring the day, our skin uses its energy to protect itself. A perfect day, All Day All Year accompanies it by acting as a global protective shield. Protects the skin by activating its self-defense mechanisms* to keep it younger, longer.
To develop All Day All Year, Sisley Laboratories studied the environmental and endogenous factors to which we are exposed during our lives. These factors, which are grouped under the scientific term Exposome, include solar radiation, pollution, smoking, etc. They are responsible for 80% of skin aging.
The complex and highly concentrated formula of All Day All Year protects the skin from 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 all day*, thanks to its encapsulated filters that do not penetrate the skin**/***.
- against polluting agents to limit their penetration into the epidermis***.
At 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.

A global shield that immediately protects the skin on the surface, strengthens its resistance and stimulates its natural power*.

The comfortable and melting texture leaves a velvety, non-shiny finish on the skin and allows you to proceed with make-up immediately after application.
Its glass bottle has been designed to be recyclable, thanks to the removable internal pocket and the use of glass compatible with recycling techniques.

The skin's defense power is strengthened*. It is smoother, softer and full of comfort. Wrinkles and fine lines are attenuated, the skin is denser. It is more beautiful and brighter and appears younger, longer.
