Sisleÿa L'Intégral Anti-Âge Firming Concentrated Serum

A concentrated anti-ageing serum from Sisley-Paris that targets loss of firmness and deep wrinkles. Silky in texture yet richly nourishing, it suits skin seeking intensive firming and regenerative support. Best for mature or visibly lax complexions, its serum form layers smoothly under creams and treatments without feeling heavy.
