Introduction: Currently there is a growing demand for non-invasive therapies aimed at treating facial aging. Non-ablative fractional lasers lead to excellent outcomes, with reduced side effects. Objective: To evaluate the facial rejuvenation achieved by 1,340nm non-ablative fractional laser using a single pass at high energy versus three passes at medium energy, through a prospective comparative study. Methods: Twenty patients with facial aging were treated with 2 or 3 laser sessions with 4-week intervals. The right hemiface was treated with three passes of 1,340nm non-ablative fractional laser at a fluence of 90 mJ, pulse duration of 5ms and 100 mtz/ cm2. The left hemiface was treated with a single pass of the same laser at a fluence of 120 mJ, pulse duration of 5ms and 100 mtz/cm2. The evaluated variables were spots, wrinkles, porphyrins and overall appearance. Results: The patients (n = 20) were evaluated during 6 to 24 months. The photographic evaluations demonstrated a significant improvement of the spots on the right hand side and wrinkles on the right and left hand sides. Eighteen of the 20 patients reported satisfaction with the treatment. Conclusion: 1,340nm non-ablative fractional laser was proven as a modern, safe and effective alternative for facial rejuvenation. For spots, the triple passes at medium energy protocol led to a superior response. However, regarding wrinkles there was no difference between the single pass at high energy and triple pass at medium energy protocols.

Necrobiosis Lipoidica (NL) is a granulomatous dermatosis, mainly affecting people with diabetes due to collagen degeneration. Although there are different treatments, all have little response. Among the options, the Intense Pulsed Light (IPL) and the Laser Erbium-YAG enhance the production and remodeling of the collagen treating the atrophy, besides reducing the erythema by the coagulation of blood vessels. We report a case of a 24-year-old woman with type I Diabetes Mellitus who underwent NL treatment on her left forearm in seven sessions with the association of IPL and 2940 nm Erbium-YAG laser. We observed improvement in central atrophy and erythema.

Solar lentigo is present in 90% of the population over 50 years of age andcharacterizes as hyperchromic spots in photoexposed regions. It increases with aging and is more frequent in light skin. There are several therapeutic modalities, which achieve better results whenassociated. We describe the case of a 62-year-old man with Fitzpatrick skinphototype II, complaining of brownish macules in nasal dorsum for eight years. The patient underwent a skin biopsy, and the histological study confirmed solar lentigo. The patient was treated with six sessions of Intense Pulsed Light associated with Erbium-Yag2940 nm Laser with a good clinical result.

Facial surgeries are often challenging for surgeons due to their complex anatomy, aesthetic and functional importance. Interventions in the cosmetic subunit that comprises the eyebrows can be particularly difficult. This case report aims to demonstrate the use of island flap in this region. We performed the excision of melanocytic nevus, with a good outcome and absence of postoperative complications. This technique is commonly used for facial reconstruction; however, the literature describes only a few cases using this method for eyebrow reconstruction.
