The dermis is made up of cells dispersed in an extracellular matrix (ECM) containing fibres (collagen and elastic fibres) and a fundamental substance. The dermis absorbs shocks and gives the skin its essential properties of elasticity, spontaneous tension and strength. Two types of forces are exerted on this connective tissue:
FIBROBLASTS are cells capable of perceiving and responding to mechanical stimulations through various biochemical reactions. These stimulations actually send a message to the fibroblasts and trigger natural biological responses, such as the production of collagen, elastin and other molecules secreted by the fibroblasts and involved in the remodelling of the ECM.
MASSAGE is a therapeutic technique that fights stress, anxiety, muscle fatigue, insomnia and nervous tension. At the skin level, massage makes the epidermis more supple and elastic, improving the aesthetic qualities of the skin tissue. Applied to the dermis, massage provides mechanical stimulation. The application of this external force can then induce the modification of the behaviour of dermal fibroblasts within their ECM.
Based on this information, we evaluated the effects of endermologie® face in 30 volunteers who underwent a treatment on hemi=face. The beneficial effects of this treatment were observed by both the volunteers and the doctor based on a clinical rating. The different clinical measures and biopsies analysis examination showed: stimulation of the production of collagen, elastin and hyaluronic acid (+80%), remodelling of the dermis and improvement in the signs of skin ageing (firmness, brightness and wrinkles).
