A unique formula


With age, skin undergoes loss of firmness in varying degrees according to facial areas:

  • The neck thickens, especially on round faces.
  • The cheeks hollow, especially on thin or square faces.
  • The skin thins and slackens.

Sisley has studied the mechanisms that alter its structure and designed a powerful combination of targeted botanical active ingredients to help the face recover the contours and resilience of younger skin.

Sisleÿa Serum Firming Serum specifically acts on 3 major targets


1 - The oval of the face is redesigned, the neck is refined
2 - The cheeks appear fuller, volume is restored
3 - Instantly smoothed skin
