I was recently introduced to this firming concentrated serum during a press launch. As a great fan of Sisley products (as they always deliver what they promise) I was quite excited when this product launched. This concentrated serum is an upgrade from the serum that was released in 2010.
This firming concentrated serum is more powerful and provides a unprecedented firming effect by targeting 2 new physiological modes of action: wakening elastin production at its origin, and total action on the forces of skin tension.
The effect is the pull up of sagging volumes while the skin is reshaped. Use is up to two month to see the full effect ( I have just started but can see the benefits already).
It does not clash with other products and you can layer from here. For instance with the Sisley nourishing cream I will tell you all about on another occasion.
Sisleÿa Firming Concentrated Serum is available from the 1st of August 2018 (30 ml | € 390)
