Facial Aging

The investigators aim to examine how FaceAge estimates (a measure of biological age based on facial features) change across different time points and identify factors that may influence these changes. This will help the investigators understand the consistency and reliability of the FaceAge algorithm and allow them to make improvements.

This study aims to evaluate the potential effects of mesenchymal stem cell-derived suspended exosome therapy on facial skin quality using objective imaging analysis. Forty adult participants will receive intradermal exosome applications in three treatment sessions performed at one-month intervals. Facial skin analysis will be conducted using the VISIA imaging system before each treatment session and six months after the final treatment. The study will examine changes in multiple facial skin characteristics including wrinkles, pigmentation, skin texture, pores, UV spots, red areas, brown spots, and porphyrins to determine whether exosome therapy may improve overall facial skin quality.

This multicenter, prospective, randomized parallel-controlled, assessor-blinded clinical trial aims to address the core clinical pain point of lack of high-level evidence and non-standardized operation in injection site selection for BTX-A treatment of oral commissure ptosis. A total of 266 eligible subjects will be randomly assigned in a 1:1 ratio to receive either upper DAO or lower DAO BTX-A injection. The study will compare the clinical efficacy, time-effect characteristics and safety profiles of the two regimens, and conduct stratified analysis of treatment response in different patient subtypes. The results will determine the optimal injection site for Chinese population, establish standardized operation specifications, fill the international evidence gap, and provide level I evidence for clinical practice.

Secretome treatment for facial rejuvenation

This study aims to investigate the effects of a single session of facial rejuvenation acupuncture on skin structure and personal satisfaction with facial appearance. As facial aging involves complex changes in muscles, skin, and soft tissues, facial acupuncture is considered a potential minimally invasive treatment to help restore balance and promote tissue repair. Researchers will enroll 60 healthy adults aged 30 to 60 who are concerned about facial aging. Participants will be randomly assigned to either an immediate intervention group or a waitlist control group. The intervention group will receive one session of facial acupuncture at the start of the study. The control group will continue their normal daily skincare routine for 6 weeks, after which they will receive the same single acupuncture treatment. All participants will be monitored weekly for 6 weeks. The research team will use non-invasive tools, including high-frequency skin ultrasound, 3D facial scanning, and a digital complexion analysis system, to objectively measure changes in skin thickness, facial volume, and wrinkles. Participants will also complete questionnaires at various time points to share their satisfaction with their appearance, self-confidence, and quality of life.

The goal of this clinical study is to learn whether the Bridging Technique can safely and effectively treat nasolabial folds (NLF, also known as smile lines) in adults. The main questions are: Does the Bridging Technique, which places very small amounts of filler in thin horizontal threads (less than 0.05 milliliters \[ml\] per retrograde placement), improve the appearance of nasolabial folds? Is the treatment safe, and are participants satisfied with the results? The Bridging Technique is a new method of filler injection where very small amounts of hyaluronic acid (HA) filler are placed in thin horizontal lines under the fold using a blunt cannula. These small "bridges" of filler act like internal support, helping to lift and soften the fold without overfilling or distorting the natural shape of the face. Participants will: Receive an HA dermal filler (AILEENE Vol. 2) injected with the Bridging Technique to both nasolabial folds. Attend follow-up visits at Week 2 (virtual safety check), Week 4, Month 3, and Month 6. Have photographs taken at baseline, Week 4, Month 3, and Month 6, which will be reviewed by independent observers who are blinded to the visit sequence. Complete short questionnaires about their satisfaction and experience. The study includes 60 adults aged 30 to 65 years. Each participant may receive up to 1.0 ml of filler in total across both folds. An optional top-up treatment may be offered at Week 2 or Week 4 if clinically indicated, using only the remaining balance of the total 1.0 ml allowance. Any top-up will be performed with a new, sterile syringe, not with filler physically left over from the first visit. There is no cost to participants, and participation is voluntary.

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 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.
