Table 2 Results of laser-assisted facial contouring on the middle and lower thirds of the face
Middle third ■ Reduction in thickness of the nasolabial fold
■ Reduction/elimination of nasolabial ptosis associated with a sagging appearance
■ Reduction of the anterior projection of submalar fat
■ Reduction of the malar crease, with increased luminosity of the cheekbone
■ Smoothing of the union of the eyelid with the cheek ■ Improved appearance of the submalar triangle ■ Reduced appearance of loss of volume ■ Reduced need for complementary filling ■ Overall contraction of the skin and surrounding tissue
Lower third
■ Reduction of the herniation of perioral fat that leads to bulges
■ Improved mandibular line, leaving a more youthful profile
■ Reduced presence of the fold anterior to the cheek ■ Reduced need for complementary filling
■ Improved roundness of the lower third and the facial triangles, which in turn reduces the classic ‘squaring’ brought on by ageing
■ Marked retraction of the skin and surrounding tissue

Material and methods Study design The authors performed a randomised double-blind study at Instituto M• dico L‰ ser, Madrid. The study population comprised 124 patients (Table 1), all of whom were women aged over 18 years (mean age 54.2 years). Patients were
instructed not to undergo any other treatment on the same area for the duration of this study. Written informed consent was obtained from all patients, and follow-up was scheduled to last 3 months. The study protocol complied with the guidelines of the
Declaration of Helsinki (1975) and was approved by the local Ethics Committee of Instituto M• dico L‰ ser. The exclusion criteria were as follows:
■ Active or chronic skin disease ■ Inflammation or other symptoms (cancerous or precancerous lesions) in the treatment area or neighbouring areas
■ Presence of non-reabsorbable fillers in the treatment area
