To Evaluate the Safety and Efficacy of Poly-L-lactic Acid Implants for the Correction of Nasolabial Folds

The goal of this clinical trial is to evaluate the safety and effectiveness of a poly-L-lactic acid (PLLA) dermal implant for the correction of nasolabial folds. The study also aims to determine whether the investigational product (FUYANMEI Poly-L-Lactic Acid) is non-inferior to the control product (Sculptra). The main questions it aims to answer are: * Is the effectiveness rate based on the Wrinkle Severity Rating Scale (WSRS) at 6 months after injection for the investigational group non-inferior to that of the control group? * How does the investigational product perform in terms of global aesthetic improvement as assessed by blinded evaluators and by subjects? * What is the safety profile of the investigational product, including the incidence, severity, and relatedness of adverse events (AEs), serious adverse events (SAEs), and device deficiencies (DDs)? Researchers will compare the investigational PLLA implant to an approved PLLA implant using a prospective, randomized, evaluator- and subject-blinded, single-center, split-face controlled study design. Approximately 121 eligible participants will be enrolled. Participants will: * Receive treatment with the investigational product and the control product according to the split-face design * Be followed for 24 months after injection * Return to the clinic at 1, 3, 6, 12, 18, and 24 months post-injection for follow-up visits * Undergo blinded evaluator assessments of WSRS and Global Aesthetic Improvement Scale (GAIS) * Complete subject self-assessments of GAIS and treatment satisfaction * Be monitored throughout the study for adverse events, serious adverse events, and medical device deficiencies

Bridging Technique Validation for Nasolabial Folds JN-BRIDGE-1

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.

Performance and Safety of Semical Dermal Fillers in Facial Rejuvenation

The aim of the study is to verify safety and performance of Semical dermal fillers according to real-world data.

A Study in Adults Evaluating Polycaprolactone Microsphere Filler for Treatment of Moderate to Severe Nasolabial Folds

The goal of this clinical trial is to evaluate the safety and efficacy of polycaprolactone microsphere filler (Lafullen) for the correction of moderate to severe nasolabial folds in adults aged 18 and above, regardless of gender. The main questions it aims to answer are: * Does Lafullen improve wrinkle severity in the nasolabial fold area at 48 weeks post-injection (WSRS responder rate)? * Is Lafullen superior to the control product (Restylane, a hyaluronic acid filler) in terms of long-term wrinkle correction and safety? Researchers will compare Lafullen (polycaprolactone filler) with Restylane (modified sodium hyaluronate gel) to see if Lafullen provides superior wrinkle correction at 12 months post-injection. Participants will: * Receive either Lafullen or Restylane via injection in the nasolabial fold area. * Optionally receive a touch-up injection at 4 weeks after the first treatment if needed. * Undergo regular follow-up visits at 4, 12, 24, 36, and 48 weeks post-treatment. * Subjects in the Lafullen group will continue follow-up up to 72 weeks to assess long-term efficacy and safety. * Be assessed through clinical photography, pain scale (VAS), satisfaction questionnaires, and safety evaluations (e.g., AEs, vital signs, lab tests).
