To restore the toned appearance of youthful skin and defy gravity, Sisley has created Sisleÿa L'Intégral Anti-Age, a concentrated firming serum. Over the years, the face loses its lightness and firmness. Cheekbones become less full, the facial contours become blurred. With the launch of Sisleÿa L’Intégral Anti-Âge, Sisley Research goes further in its innovation and returns to the very origins of behavioral aging.
