Cellulite - an overview of non-invasive therapy with energy-based systems

Treatment of Dimpling from Cellulite

Background

Cellulite can be seen on the skin in widespread alterations of the skin surface and dimpling. The purpose of this study was to assess the effectiveness and safety of the manual subcision technique to treat dimpling from cellulite, using a specific class IIA medical device (Celluerase).

Methods

The multi-center observational study assessed 200 women treated in a single session for different dimpling, using manual subcision administered by Celluerase. Aesthetic outcomes were evaluated by the authors, and the patients assessed satisfaction levels.

Results

Two hundred women between 20 and 55 years were treated. The medical evaluation of patients saw improvements with an average score of 8.1, whereas the subjective evaluation by patients gave an average improvement score of 7.8. Adverse events were reported.

Discussion

Women have septa orientation at right angels to the skin surface, and those with cellulite have an irregular septa conformation, with some septa being hypertrophic-thickened, and others being narrowed-lysed. Magnetic resonance imaging has confirmed that cellulite depressions are associated with a significant increase of thickness of underlying subcutaneous fibrous septa. Subcision has immediate results because it eliminates traction on the skin.

Conclusion

The study has shown the effectiveness and safety of the manual subcision in the treatment of dimpling. The device used, designed specifically for this technique, has shown itself to be very helpful and effective in terms of practical use, aesthetic outcome and safety, with various advantages compared with other commonly used devices.

Cellulite: a review with a focus on subcision

Cellulite is an alteration in skin topography most often found on the buttocks and posterolateral thighs of the majority of postpubertal females. This article aims to review the background, potential pathophysiology, and potential treatment options for cellulite, highlighting subcision as an ideal therapeutic option for this cosmetically distressing condition.

Low-level laser therapy for fat layer reduction: a comprehensive review

BACKGROUND AND OBJECTIVE

Low-level laser (light) therapy (LLLT) is a noninvasive, nonthermal approach to disorders requiring reduction of pain and inflammation and stimulation of healing and tissue regeneration. Within the last decade, LLLT started being investigated as an adjuvant to liposuction, for noninvasive body contouring, reduction of cellulite, and improvement of blood lipid profile. LLLT may also aid autologous fat transfer procedures by enhancing the viability of adipocytes. However the underlying mechanism of actions for such effects still seems to be unclear. It is important, therefore, to understand the potential efficacy and proposed mechanism of actions of this new procedure for fat reduction.

MATERIALS AND METHODS

A review of the literature associated with applications of LLLT related to fat layer reduction was performed to evaluate the findings from pre-clinical and clinical studies with respect to the mechanism of action, efficacy, and safety.

RESULTS

The studies as of today suggest that LLLT has a potential to be used in fat and cellulite reduction as well as in improvement of blood lipid profile without any significant side effects. One of the main proposed mechanism of actions is based upon production of transient pores in adipocytes, allowing lipids to leak out. Another is through activation of the complement cascade which could cause induction of adipocyte apoptosis and subsequent release of lipids.

CONCLUSION

Although the present studies have demonstrated safety and efficacy of LLLT in fat layer reduction, studies demonstrating the efficacy of LLLT as a stand-alone procedure are still inadequate. Moreover, further studies are necessary to identify the mechanism of action.

Ultrastructural assessment of cellulite morphology: clues to a therapeutic strategy?

INTRODUCTION AND AIMS

Cellulite is a problematic condition affecting mostly women, characterized by a bumpy or nodular skin surface. Recent approaches with laser treatment have offered some promise. The present study sought to identify possible targets for laser treatment or light therapy through an ultrastructural investigation of the condition.

SUBJECTS AND METHODS

Study subjects comprised 7 healthy Japanese female volunteers (Age range 37-46 yr, average 38.4) with cellulite, graded on the 4-point Nurnberger-Muller cellulite severity scale. Four patients were at grade 2 and 3 at grade 3. Three millimeter punch biopsies were obtained and routinely processed for light and transmission electron microscopy.

RESULTS

Microphotography of specimens from cellulite patients demonstrated the presence of fibrotic septa which divided up larger clusters of adipose tissue into smaller packets, with the septa acting as a tethering system, thus producing the typical dimpling pattern. Ultrastructural findings showed proliferation of collagen and elastic fibers down into the cellulite tissue with compression of capillaries and congestion of arterioles, resulting in poor blood flow.

CONCLUSIONS

The histological and ultrastructural findings of cellulite clearly distinguish the condition from simple fat deposition. The remodeling of the fat layer into lobulated packets of lipocytes sequestered by fibrotic septa with a high proportion of elastic fibers would suggest the use of a fiber-based interstitial laser-assisted lipolysis system at an appropriate wavelength which might offer benefits through disruption of the septae through a photomechanical effect and lipolysis of the sequestered lipocytes. This could be followed by a course of near-infrared phototherapy to accelerate clearance of freed lipid and debris and reestablish the vascular system.
