Tear Trough Rejuvenation With Injectable Biostimulatory Polynucleotides (VAMP)
Bibliographic record
Abstract
Tear trough rejuvenation presents a clinical challenge due to thin skin, superficial vasculature, and age-related volume loss. VAMP, manufactured by Prollenium, a polynucleotide-based biostimulatory injectable, is designed to support dermal regeneration and improve skin quality without volumizing excess. The objective of this study was to evaluate early clinical outcomes after VAMP injection in the tear trough area. Five healthy female patients (aged 35-50 y) of Middle Eastern and White descent were treated with 2 mL of VAMP (1 mL per side) using a 23G 30-mm SoftFil microcannula. The product was delivered via a combined microdroplet and linear threading technique to enhance distribution. Follow-up assessments were conducted at 1 week, 2 weeks, 1 month, and 3 months. Evaluation included standardized clinical photography, patient-reported satisfaction, and assessments of texture, tone, pigmentation, and contour. Mild to moderate improvements were observed in tear trough appearance, skin smoothness, and pigmentation. No adverse events were reported within the follow-up period. However, the limited sample size and short duration preclude definitive conclusions. Preliminary results suggested that VAMP may offer a promising option for tear trough rejuvenation. Further studies with larger cohorts and extended follow-up beyond 6 months are warranted.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
