SAGE Journals Publishes New Data Revealing NEXGEL’s SilverSeal Hydrogel Dressing Improves Postsurgical Scarring

 Patients Treated with SilverSeal Experienced Significantly Less Scarring and Improved Skin Functionality Following Surgical Incision

LANGHORNE, Pa., Oct. 03, 2022 (GLOBE NEWSWIRE) -- NEXGEL, Inc. (NASDAQ: NXGL, NXGLW), (“NEXGEL” or the “Company”), a leading provider of ultra-gentle, high-water-content hydrogel products for healthcare and consumer applications, announced today that SAGE JournalsScars, Burns and Healing publication, a peer-reviewed journal that focuses on scar and burns research, has published new data from a study evaluating the impact of NEXGEL’s SilverSeal® hydrogel dressing on postoperative scarring and complications. The results demonstrated significant scar improvement in patients treated with SilverSeal.

Study Design:

  • SilverSeal was used post-surgery as an antimicrobial dressing to evaluate its ability to aid in the healing process.
  • 40 foot and ankle patients (aged 32 to 66) were included in the double-blind, randomized study with 20 patients in each group.
  • Postoperatively, the treatment group was given a SilverSeal hydrogel dressing, and the control group was treated with a standard petroleum-based dressing.
  • Scarring and complications were evaluated, and follow-up was performed at two, six and 12 weeks post-surgery using the Patient and Observer Scar Assessment Scale (POSAS), which measures a scar’s quality from both the physician and patient’s perspective.
  • Patients were not excluded in the study based on gender, age or comorbidity.


  • The treatment group demonstrated statistically significant improvements in the POSAS observer score and observer opinion at six and 12 weeks (p<0.001).
  • Patients in the treatment group reported significantly reduced pain, compared with the control group, at 12 weeks (p<0.001).
  • Patients reported that itching at the surgical site declined over time for both groups (p<0.001), with significantly less itching reported by the treatment group (p=0.027).
  • The scar area considerably decreased for the treatment group compared to the control group at six and 12 weeks (p≤0.002).
  • Neither group experienced post-operative complications.

“Surgical incisions all result in scar formation, some more pronounced than others,” said Dr. Stephen Brigido, Section Chief of Foot and Ankle Reconstruction and Fellowship Director at the Orthopedic Institute at Lehigh Valley Hospital. “As skin heals and scar formation occurs, patients often experience discomfort such as sharp pain, burning and itching. After 12 weeks of observing these patient groups, we saw noteworthy differences when comparing the control group with the treatment group. We found that patients treated with NEXGEL’s SilverSeal hydrogel dressing experienced significantly less negative symptoms and regained their skin functionality quickly. We also found that the overall scar area significantly decreased in patients who used SilverSeal.”

Dr. Brigido continued, “The most important result we observed was a significant decrease in skin and scar incisional pain experienced by patients in the hydrogel group, which was observed throughout the study. As a surgeon, this suggests a marked change in how patients undergoing surgery should be treated. These results are promising for not only for foot and ankle surgery but also for healing all postsurgical incisions.”

The study took place at Lehigh Valley Orthopedic Institute.
