Since its creation, Institut Esthederm has seen the skin as an ecosystem that's constantly interacting with its environment, and whose natural mechanisms must be respected in order to preserve its health and beauty in the long term. The brand offers a wide range of products tailored to all skin types. One of their must-haves? The high-performance Absolute Tightening Serum. This product smooths the facial features day after day. Its dual effectiveness provides an immediate tightening effect and smooths the skin's microrelief. It redefines the contours of the face thanks to its biological action, which restructures, regenerates and firms the skin.
