Background: Aesthetic medicine procedures became popular influencing perceptions of beauty. Attractiveness is shaped by factors such as sex, ethnicity, and level of familiarity. Repeated exposure to over-treated faces may change the sense of aesthetic norms potentially influencing the way of performed treatments.

Objective: The aim of the study was to investigate how exposure to faces that have undergone excessive aesthetic treatments influences facial perception and the evaluation of attractiveness, masculinity, and femininity by medical and nonmedical observers.

Methods: Sixteen pictures (14 modified and 2 unmodified) of female and male models were observed and assessed by 50 volunteers of Polish origin. The study was conducted in 2 phases, both involving eye-tracking and survey evaluations of the same faces. After 4 weeks, same assessment was repeated after exposure to "drift inducers," which were 50 images of individuals who had undergone excessive aesthetic procedures resulting in an artificial appearance.

Results: Medical and nonmedical observers showed no differences in time to first fixation or total fixation duration. No difference in gaze patterns has been found between 2 phases of the study. However, female modified lips were evaluated more feminine by physicians.

Conclusion: Participants with medical background tend to evaluate modified faces more negatively than random observers. However, overfilled lips are the most acceptable facial modifications among them which may result from visual adaptation effect, especially after cumulative exposure.

Background: Hyaluronic acid (HA) is a cornerstone of aesthetic skin treatments due to its vital role in skin hydration and combating aging signs.

Objective: This trial evaluated the efficacy and safety of a novel non-cross-linked HA gel for improving skin quality in a Chinese population.

Materials and methods: In this multicenter, randomized, controlled trial, 420 subjects were enrolled (2:1, treatment: control). The treatment group received three full-face intradermal injections of the HA gel at 3-week intervals, whereas the control group received no intervention. Primary end points were blinded evaluations of the Global Aesthetic Improvement Scale and a composite improvement rate for skin dryness/dullness.

Results: The treatment group showed significantly higher Global Aesthetic Improvement Scale improvement (90.63% vs 3.65%) and composite improvement rates (83.20% vs 3.65%) than control group (p < .0001), with effects sustained for 6 months. Skin hydration and elasticity significantly increased from baseline (p < .05). Peak efficacy rates for fine lines and roughness reached 51.59% and 50.00%, respectively. Adverse events were mild and transient, with decreasing incidence.

Conclusion: This non-cross-linked HA gel effectively enhances skin hydration, elasticity, and texture with sustained 6-month benefits and a favorable safety profile, supporting its use for facial rejuvenation.

Background: Genital and inguinal cutaneous malignancies are uncommon but clinically significant because of complex anatomy and potential morbidity. Nevertheless, these sites remain underrepresented in dermatologic surgery literature and training.

Objective: To practically review the anatomy relevant to cutaneous oncologic surgery of the male and female genitalia and inguinal region, emphasizing landmarks, danger zones, safe planes, and reconstruction.

Methods: A review was conducted. Clinical series, cadaveric studies, and reviews most applicable to dermatologic surgery were prioritized.

Results: Surface landmarks such as the penile and scrotal raphes, clitoral hood and fourchette, and the inguinal ligament help orient dissection. Safe undermining planes include the subdartos tissue of the penis and scrotum and tissue superficial to Scarpa fascia in the groin. Critical danger zones include the dorsal penile and clitoral neurovascular bundles, the ventral urethra at the frenulum and urethral meatus, the Bartholin glands at the posterior vestibule, and the femoral neurovasculature within the femoral triangle.

Conclusion: As Mohs micrographic surgery is increasingly applied to genital and inguinal tumors, dermatologic surgeons will play a growing role in their management. Safe outcomes depend on respecting fascial planes and danger zones, and the principles summarized here provide a practical framework for excision and reconstruction.
