Background: Perioral wrinkling is commonly reported among older adults, but its objective evaluation and causes remain poorly understood.
Objective: We sought to develop a photonumeric scale for perioral wrinkling and to elucidate contributory lifestyle factors.
Methods: In this cross-sectional study, we recruited participants for facial photographs and a survey. A gender-specific photonumeric scale for perioral wrinkling was developed and used by 3 graders to evaluate participant photographs. Scores and survey responses were used to create a multiple regression model to predict perioral wrinkling.
Results: In all, 143 participants aged 21 to 91 years were enrolled. Intraclass correlation coefficient values for interrater and intrarater reliability were high (>0.8) across 2 trials and 3 graders. A multiple regression model for prediction of perioral wrinkling severity included age, gender, and years of smoking as variables.
Limitations: The study was limited by sample size and a predominantly Caucasian study population.
Conclusion: We created a photonumeric scale that accounts for gender differences in perioral wrinkling and highlighted contributory variables to photoaging in this anatomical location.

Background: Radiofrequency-assisted (RF) facial rejuvenation has become a safe and reliable option for "treatment gap" patients, including (1) patients whose skin laxity is not severe enough to warrant a facelift, yet not mild enough to reliably treat with noninvasive procedures; (2) patients who have already undergone a face or neck lift and have recurrent laxity; and (3) patients who would benefit from a traditional face or neck lift but want to avoid surgery and are willing to accept a more modest improvement without extensive surgical scar burden and recovery.
Objectives: In this study we aimed to educate the reader about providing bipolar RF to various anatomic regions of the face.
Methods: A retrospective review of cases was conducted to assess the safety of zone-specific RF-assisted facial rejuvenation in S.

Background: Perioral rejuvenation is challenging due to the lack of spatial anatomical understanding of the labiomandibular fold (LMF). The LMF's formation mechanism remains underexplored due to intricate relationships between musculature and subcutaneous structures. This study aimed to clarify the three-dimensional structures of the LMF using micro-computed tomography and histology.

Objective: Substantial efforts have been progressively devoted to developing innovative, safe, and effective topical anti-aging products that not only improve the appearance of aged skin but also prioritize environmental sustainability and the responsible use of natural resources. Thus, the current study targeted to evaluate novel, natural emulsion/serum comprising new glycolipid emulsifier (lauryl glucoside/myristyl glucoside/polyglyceryl-6 laurate) and Acmella oleracea plant extract as a model active.
Methods: The developed serum was assessed concerning its stability (freeze-thaw test, accelerated study), safety (in vitro screening of eye irritation potential, dermal absorption study) and efficacy (randomized, active/reference-controlled, half-face, in vivo study).

Perioral rejuvenation is a critical component in the comprehensive approach to the aging face. The perioral region-comprising the lips, philtrum, and areas surrounding the oral commissures-plays a significant role in an individual's perceived age, attractiveness, and emotional expressions. However, the perioral region is often the "forgotten area" and has the potential to undermine the success of otherwise outstanding rejuvenation surgeries.
