Bottom Line: A significant improvement of different clinical signs associated with skin aging and the satisfaction of the subjects were observed, correlated with an improvement of the sagging cheek.Mécano-Stimulation is a noninvasive and safe technique delivered by flaps microbeats at various frequencies, which can significantly improve the skin trophicity.Results observed with objective measurements, ie, in vitro assessments and electron microscopy, confirm the firming and restructuring effect clinically observed.

ABSTRACT

Background: Loss of mechanical tension appears to be the major factor underlying decreased collagen synthesis in aged skin. Numerous in vitro studies have shown the impact of mechanical forces on fibroblasts through mechanotransduction, which consists of the conversion of mechanical signals to biochemical responses. Such responses are characterized by the modulation of gene expression coding not only for extracellular matrix components (collagens, elastin, etc.) but also for degradation enzymes (matrix metalloproteinases [MMPs]) and their inhibitors (tissue inhibitors of metalloproteinases [TIMPs]). A new device providing a mechanical stimulation of the cutaneous and subcutaneous tissue has been used in a simple, blinded, controlled, and randomized study.

Materials and methods: Thirty subjects (aged between 35 years and 50 years), with clinical signs of skin sagging, were randomly assigned to have a treatment on hemiface. After a total of 24 sessions with Mécano-Stimulation™, biopsies were performed on the treated side and control area for in vitro analysis (dosage of hyaluronic acid, elastin, type I collagen, MMP9; equivalent dermis retraction; GlaSbox(®); n=10) and electron microscopy (n=10). Furthermore, before and after the treatment, clinical evaluations and self-assessment questionnaire were done.

Results: In vitro analysis showed increases in hyaluronic acid, elastin, type I collagen, and MMP9 content along with an improvement of the migratory capacity of the fibroblasts on the treated side. Electron microscopy evaluations showed a clear dermal remodeling in relation with the activation of fibroblast activity. A significant improvement of different clinical signs associated with skin aging and the satisfaction of the subjects were observed, correlated with an improvement of the sagging cheek.

Conclusion: Mécano-Stimulation is a noninvasive and safe technique delivered by flaps microbeats at various frequencies, which can significantly improve the skin trophicity. Results observed with objective measurements, ie, in vitro assessments and electron microscopy, confirm the firming and restructuring effect clinically observed.

Clinical scoring of skin radiance: color skin complexion heterogeneity.Notes: The scoring of the radiance was also assessed through color parameters: skin complexion heterogeneity score was evaluated with an analogical scale (from 0= homogeneous to 9= heterogeneous) and is presented before (T0) and after (T1) the 24 sessions of treatment. At T1, the score was significantly improved (decrease) on the treated side (blue) compared to the nontreated hemiface (red); a significant improvement in terms of time/treatment evolution was observed. Skin complexion heterogeneity score was improved by 13.8% on the treated side while a worsening was noticed on the nontreated side (+1.2%). *P<0.05.Abbreviation: T, time.

Mentions: At T0, no difference between the treated and the untreated hemiface was observed for the clinical scores of skin color (except for buttons/spots, P=0.086). At T1 compared to baseline, heterogeneity, under-eye dark circles, papules/scars, and color score were significantly improved on the treated hemiface, while they were stable on the nontreated hemiface. A significant improvement in terms of time/treatment evolution was observed for all parameters (skin complexion heterogeneity, under-eye dark circles, redness, and color score) (Table 4 and Figure 6). An improvement for treated versus nontreated side was observed on the following parameters:
