Perioral Wrinkles

The goal of this observational study is to learn how a perioral rejuvenation procedure affects perioral line severity and lip volume over time in adults undergoing routine aesthetic treatment in a single clinical center. The main questions it aims to answer are: * What proportion of participants achieves a ≥1-point improvement from baseline on both the Lip Fullness Scale (LFS) and the Static Perioral Lines Assessment Scale (SPLAS) at Week 12? * How do skin wrinkling/surface roughness, lip and perioral volume, and patient satisfaction change over 6 and 12 weeks? Participants will: * Receive a routine (non-study-mandated) holistic perioral rejuvenation procedure as decided by their treating clinician. * Attend study visits at approximately baseline, Week 6, and Week 12. * Undergo independent clinical assessments (assessor not involved in treatment delivery) of LFS and SPLAS. * Have skin wrinkling and surface roughness documented by VISIA skin analysis (baseline, Week 6, Week 12). * Have lip and perioral volume measured by VECTRA M3 volume analysis (baseline, Week 6, Week 12). * Complete a standardized patient satisfaction questionnaire (Week 12).

The first goal of this clinical trial is to learn if topical application of PLLA in conjunction with a microneedling treatment works to treat perioral wrinkles in adults. The second goal is to see whether the application of topical PLLA is more effective before or after a microneedling treatment. The main questions it aims to answer are: * Is PLLA present within the MN channels from in vivo biopsy samples? * Is it safe to combine topical PLLA and MN in the treatment of perioral wrinkles, as determined by the incidence and severity of adverse events in healthy subjects? * Does overall aesthetic and skin texture improve in combining microneedling with topical PLLA in the treatment of mild to moderate perioral wrinkles? * Is it the treatment of topical PLLA more effective when applied before or after a microneedling treatment. Researchers will compare the application of PLLA before a microneedling treatment to a microneedling treatment with PLLA application after to see which treatment method is more effective. Participants will: \- receive 2 treatments spaced 4-6 weeks apart of topical PLLA and microneedling

The goal of this post-market interventional study is to confirm, under real-life conditions, the safety and performance of hyaluronic acid-based dermal fillers intended to modify skin anatomy and facial appearance. Subjects aged 18 years or older seeking aesthetic treatment of the lips, perioral lines, nasolabial folds, cheeks, and/or infraorbital hollows may be included. The main question the study aims to answer is: How long does the effect of the products last? Participants will attend follow-up visits every 6 months after the initial injection, until the end of follow-up at 24 months. During each visit, the investigator will assess performance and safety through a simple clinical examination. At each follow-up visit, subjects will also evaluate the aesthetic improvement compared with their pre-injection appearance. Subjects will be asked about the level of pain experienced during the initial injection. If the subject wishes, a retreatment may be performed at the 12-month or 18-month follow-up visit, provided that the treated area(s) have returned to the pre-injection state.
