There are extensive reports on the characteristics and therapeutic potential of adult mesenchymal stem cells. The possibility of isolating them from excess adipose tissue obtained from other procedures is promising and extremely desirable. However, the protocols for such applications are still described in a summarized, rather than standardized, manner.Thus, the objective of this paper is to present a simple, practical and effective protocol for the collection of adipose tissue in the hospital environment, and for the isolation and in vitro cultivation of adult mesenchymal stem cells obtained from adipose tissue in a laboratory, with the purpose of discussing the potential uses of this technique in the field of dermatology.

Gynoid lipodystrophy (cellulite) is a common, unattractive dermatosis that affects many women around the world. Depending on the severity of the appearance, the condition may cause important psychosocial disorders. Many therapies have been clinically tested, and many have been proscribed, not only for their therapeutic inefficiency, but also for their risk to patients’ health. Other treatments, notwithstanding their weak scientific basis, are still in vogue. Medical devices, few of which are backed by actual scientific evidence, also currently claim to help treat this condition. This paper provides an extensive scientific literature review and analysis, and aims to help dermatologists decide what specific therapies to recommend and provide assurances regarding the clinical rationale of results when treating patients with this condition.

In the literature there is significant confusion between the terms hypodermis and subcutaneous adipose tissue, which are often used interchangeably. They are however two distinct and independent structures, with independent metabolic responses. The distinction between these two layers and the knowledge of their behavior is of crucial importance for choosing the appropriate treatment. The objective of the present study was to review the existing literature on the topic, in order to demonstrate the anatomical and histological differences between the two tissues.

Introduction: Introduction: Not focused ultrasound is a noninvasive alternative to improve body contour.
Methods: It's reported five cases treated with eight weekly sessions of not focused ultrasound on the abdomen.
Results: The treatment did not affect the routine of patients; it was comfortable and safe for most. There was a reduction in the thickness of the fat layer evaluated by ultrasound and in the circumferential measures in all patients, with clinical improvement evidenced in the photographic documentation especially in patients with lesser thickness of subcutaneous.
Conclusion: The device was safe, and was shown clear reduction in abdominal subcutaneous tissue.

Cryolipolysis is known worldwide as an effective and safe treatment for the reduction of localized body fat. A review of the current literature on the subject was carried out, including possible complications of the technique.

Lipomas are frequent soft tissue tumors and can be found anywhere in the body; however, their location in hand is rare. They are called giants when they exceed 5 cm. In these cases, the differential diagnosis must be made with liposarcoma. These benign tumors must be characterized preoperatively with an imaging study, and their treatment is surgical. We present the case of a patient with a giant hand lipoma successfully treated with a modified Bruner incision approach.

The search for aesthetic procedures aimed at the loss of submental definition is increasing. A correct diagnosis is imperative for successful treatment and the reduction of complications. Localized adiposity, skin flaccidity, and loss of bone structure are the main findings. A treatment algorithm was discussed in this review, remembering, of course, the possibility of combined and sequential treatments for better results.

We developed a narrative literature review on the association of fat grafting and hair transplantation using the Follicular Unit Extraction (FUE) technique in scalp scars. Data were collected from studies found in Medline, Lilacs, and IBECS databases. Bibliographical records of several authors who researched mesenchymal cells in adipose tissue were cited, describing the techniques used. The conclusion was that the two-stage hair transplantation technique, with previous fat transplantation, is effective, according to the reviewed articles.

Autologous fat grafting is a common option for the correction of facial asymmetry. Recently, therapies using injectable substances that promote lipolysis have emerged to reduce undesired fat volume, offering an alternative to surgical removal of adipose tissue. We report an experimental case in which fat-dissolving injections were used to correct facial asymmetry following fat grafting, demonstrating satisfactory results with a minimally invasive procedure.

The clinical use of combined technologies has been increasing to address the effects of skin aging on the face and other areas of the body. Poly-L-lactic acid is a biocompatible, semipermanent synthetic filler used for volume enhancement through neocollagenesis induction by fibroblast activation. Similarly, energy-based technologies, such as high-intensity focused ultrasound and microneedling radiofrequency devices, promote fat reduction and collagen contraction by heating the deep dermis. This article presents expert panel recommendations and a literature review on the topic.
