Protocol for the Use of Poly-L-Lactic Acid (Elleva and Elleva X) for Skin Flaccidity in Body Areas

Patrícia Leite Nogueira*, Mirele Renata Fadel de Morais Teodoro

Poly-L-Lactic Acid (PLLA) is a synthetic, biodegradable, resorbable and biocompatible polymer. Its use in the treatment of facial rejuvenation is already widely known, while its use to improve flaccidity and body contour has also been proposed, with reproducible and scientifically proven results. It is currently estimated that the greatest use of biostimulators in the Brazilian market is aimed at body treatments. One of the justifications for this behavior is the fact that Brazil is a tropical country, with a hot climate, in which body exposure and appreciation of body beauty are culturally evident.

Purpose: The purpose of this study is to suggest a restoration and application technique of PLLA, Rennova Elleva^® (E_R-Rennova Elleva^®, Ghana R&D CO, LTD-South Korea) and Rennova Elleva X^® (EXR-Rennova Elleva X^®, Ghana R&D CO, LTD-South Korea), for the treatment of body flaccidity, through a simplified and reproducible method.

Methods: For body use, E_R must be diluted in 20 ml of injectable water and 4 ml of lidocaine, forming a final solution of 24 ml that must be distributed across the superficial subcutaneous plane through 8 fan-shaped applications of 3 ml each, through 6 linear retrograde injections of 0.5 ml in each fan.

Results: With the restoration and application technique described, there is an improvement in the sagging and firmness of the skin, as well as in the appearance of the areas affected by cellulite.

Conclusion: This article has a methodology for the application of E_R and EX_R PLLA for the treatment of different body regions, their restoration, and a standardization of marking in 8 fans for the body region.
