Clinical trials

This is a prospective, randomized, controlled clinical investigation designed to evaluate the performance and safety of DMFI300 for the treatment of nasolabial folds. 30 adult participants will receive treatment with the investigational device and the comparator device using a split-face design. The study will assess wrinkle severity using validated aesthetic evaluation scales, as well as overall safety.

This is a prospective clinical investigation designed to evaluate the performance and safety of DMFI150 for the treatment of nasolabial folds. 30 adult participants will receive a single treatment with the investigational device. The study will assess wrinkle severity using validated aesthetic evaluation scales, as well as overall safety.

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).
