L-Lift Technique Using Poly-l-Lactic Acid: A Pilot Study

Abstract

BACKGROUND Minimally invasive procedures that prevent and delay the aging process can be an alternative to more invasive surgical procedures. OBJECTIVE To assess the efficacy and safety of L-Lift technique to improve skin firmness, facial global aesthetics, and the patient and investigator satisfaction. METHODS Prospective, open, single-center study. Thirty participants underwent 3 treatment sessions 1 month apart and were assessed 8, 16, and 24 weeks after first injections. Assessments included the Facial Laxity Rating Scale (FLRS), Global Aesthetic Improvement Scale (GAIS), objective measurement of skin elasticity, and the Skin Distension Test. RESULTS At Week 24, 60% of the patients had at least 1-class improvement in the FLRS for the middle face and 33% for the lower face. At Week 24, investigators considered that 90.0% of the patients improved according to the GAIS and 90.0% of the subjects considered they have improved. Skin elasticity (at Week 8 and at Week 16) and Skin Distension Test (at Week 24) assessments indicated improvement in skin firmness. Both patients and investigators were satisfied with the treatment at the study end. CONCLUSION The technique is safe and efficacious. It may be particularly suitable for patients presenting initial signs of facial skin laxity.

Optimal Changes Seen in Patients After Treatment With Poly-l-Lactic Acid: A Retrospective Descriptive Study

“…29 The improvement of facial skin firmness, a component of skin quality, with repeated injections of PLLA is supported by the findings of a study by Hexsel and colleagues. 30 From a total of 30 patients treated, at least 1-class improvement in the Facial Laxity Rating Scale was observed in 60% of patients for the middle face and 33% of patients for the lower face. Furthermore, skin elasticity measured by using a Cutometer (Kourage & Kasaca) and by Skin Distension test assessments 31 indicated improvement in skin firmness.…”

Recent progress and clinical applications of advanced biomaterials in cosmetic surgery

“…Hexsel et al . [ 44 ] describe a new technique that enhances skin and subcutaneous tissue support by injecting small amounts of collagen stimulators into the cheekbones and preauricular area. It gently pulls up the skin, increases the firmness of the skin and delays the normal process of aging facial sagging.…”
