Skin Laxity

This single-center, open-label, intra-subject controlled proof-of-concept clinical study will evaluate the histological and clinical effects of Poly-L-lactic Acid (PLLA) LASYNPRO™ (Juläine) injections for treatment of skin laxity in patients requiring post-bariatric surgery. Fifteen participants will be enrolled. Each participant will serve as his or her own control, with one thigh treated with PLLA LASYNPRO™ and the contralateral thigh left untreated. Participants will receive 3 injections in the treated thigh over approximately 3 months, followed by planned post-bariatric plastic surgery at 3, 6, or 9 months after the last injection, depending on assigned group. During surgery, tissue samples from treated and untreated areas will be collected for histological evaluation. A follow-up visit will occur approximately 30 days after surgery. The primary endpoint is comparison of collagen type I and collagen type III between treated and untreated areas. Secondary endpoints include histological comparison of elastic fibers, stromal cell populations, inflammatory biomarkers, cell proliferation markers, and assessment of stretch marks, as well as safety. An exploratory endpoint is assessment of post-operative scar healing.

Evaluate the safety and efficacy of the fractional ablative laser for treatment of skin laxity and tightening

This study aims to evaluate the safety and effectiveness of Juläine™ (poly-L-lactic acid) injections for the treatment of buttock skin laxity. Participants will be randomized to an immediate-treatment group or a delayed-treatment group. The immediate-treatment group will receive 2 to 3 treatment sessions over up to 2 months and will be compared with the delayed-treatment group during the control period; the delayed-treatment group will receive the same treatment after the delay. The primary objective is to assess clinical improvement in buttock skin elasticity 6 months after the last treatment, defined as an increase in skin elasticity measured by a cutometer. Total study participation is up to 16 months, including follow-up. This multicenter trial will be conducted in Brazil.

The primary objective of this study is to evaluate the efficacy and tolerability of Pavise Extracellular Matrix Restore (ECMR), compared with standard acute post-operative care, when used as the primary occlusive treatment immediately following ablative CO₂ and Er:YAG facial laser resurfacing to support wound healing.

Adult subjects with moderate-to-severe cheek wrinkles will be treated with Sculptra for correction of fine lines and wrinkles in the cheek area.

The main purpose of the study is to collect information about how the device functions in a variety of treatment areas and skin types and to find out what changes, if any, occur in the skin treated with the study device compared to the skin that wasn't treated including patients receiving GLP-1's, a class of medications that mimic a natural hormone to help control blood sugar and support weight loss. The study will also evaluate side effects that occur with this treatment, if any. Standardized 2D Imaging will be used to quantify reduction of wrinkle severity

Skin laxity is a common complaint among patients seeking aesthetic dermatological interventions, affecting the facial contour, especially in the mandibular angle, due to bone aging and the loss of tissue support in the lower third of the face. Facelift surgery is an effective method to address this issue, but it is invasive and may impact the definition of the jawline. As an alternative, poly-L-lactic acid (PLLA) stimulates collagen production, improving facial contour in a minimally invasive manner. This study aims to evaluate the safety and effectiveness of a new, low-cost, and quick application technique using poly-L-lactic acid in the mandibular angle and anterior to the mandibular ligament. The proposed technique seeks to enhance facial contour, provide an additional lifting effect, and contribute to overall facial rejuvenation. This is a clinical, prospective, and interventional study, allowing the analysis of clinical outcomes in terms of efficacy and safety. Twenty volunteers aged between 18 and 65, of both genders, with no restrictions on the use of collagen bio-stimulators, will be recruited. After confirming inclusion and exclusion criteria, participants will sign the Informed Consent Form (ICF) and be eligible for the study. The first intervention will occur at visit 2 (day 1), the second intervention at visit 3 (day 30 ± 15), and the third intervention will be performed as indicated at visit 4 (day 60 ± 15). Final follow-up will take place at visit 5 (day 90 ± 15). Questionnaires will be applied and photographs taken at all visits. Injections will be administered with poly-L-lactic acid in the mandibular angle region and anterior to the mandibular ligament. The study will be funded by the Research Department of the Hexsel Dermatology Clinic, and the data collected will be used to prepare an article for publication.

The primary objective of this clinical trial is to evaluate the safety and effectiveness of the 2,910 nm mid-infrared erbium-doped fluoride fiber glass laser (UltraClear, Acclaro Medical) for non-invasive dermatological aesthetic treatment of three facial regions: eyebrow lift (Region 1), submental tissue lift (Region 2), and improvement of rhytids and skin laxity in the cheeks, midface, and jawline (Region 3).

This prospective study aims to evaluate the safety and effectiveness of Quantum, a fully internal bipolar radiofrequency probe, for the treatment of prominent skin laxity, providing patients with a more toned and youthful appearance, in patients undergoing High-Definition (HD) Liposculpture. The main questions this study seeks to answer are: * Does Quantum reduce skin laxity in patients undergoing HD Liposculpture? * Is the effectiveness in skin laxity reduction influenced by demographical factors, including age, gender, and phototype? The participants will be adult patients (between 18-60 years) undergoing HD Liposculpture, with any measurable degree of skin laxity. The participants can not be pregnant, have history of scaring/healing problems, autoimmune diseases, severe dermatological conditions, have metal implants, be obese, or have important comorbidities.

The goal of this observational study is to evaluate the effectiveness and safety of microwave-assisted heating technology in facial fat reduction and skin tightening in Asians. The main questions it aims to answer are: 1. How effective is the microwave-based system in reducing fat and tightening Skin? 2. What objective methods can be used to measure treatment outcomes? 3. What are the optimal treatment parameters for maximum efficacy? 4. What are the safety and side effects associated with the treatment? 5. How long-lasting are the results? Participants will go through three treatment sessions using the "DEKA" ONDA Microwave treatment system, with each session lasting 12 minutes.

The BECOME Study (Bovine and Marine Collagen Efficacy for Skin, Hair, Nails and Whole Body Health Markers Evaluation) is a randomized controlled trial designed to compare the effects of bovine and marine collagen supplements versus a placebo on skin, hair, nails and whole body health markers. The trial aims to determine the most efficacious collagen source for improving health outcomes and to establish if both types of collagen are equally effective. Participants will be assessed on various health parameters, including skin elasticity, joint health, digestive health, and overall well-being, over a specified period.

The goal is to know the profile of photoaging based on clinical examination, Dermoscopic Photoaging Scale and leucocyte telomere length The main questions of Research are: * what is the profile of photoaging based on clinical examination results in skin aging * what is the profile of photoaging based on DPAS Score in skin aging * what is the profile of leucocyte telomere length in skin aging Participants are female and male with the age of 29-31 years old and 59-61 years old. They will be examined by dermatovenereologist and will be photographed in 5 positions, they will get dermocopy on forehead, right cheek , left cheek, and chin, and their blood will be drawn about 10 mL in order to get the profile of leucocyte telomere length
