  Journal of Cosmetic and Laser Therapy, 2013

• Topical copper tripeptide complex on CO2 laser-resurfaced skin caused no significant reduction in erythema or objective improvement in wrinkles compared to controls, but significantly increased patient satisfaction regarding overall skin quality.

  Archives of Facial Plastic Surgery, 2006

• A novel regimen combining a hydroxy acid-based scrub and copper tripeptide serum significantly reduced adherent scalp flaking by 61.24%, increased hair density by 12.48%, increased hair thickness by 25.36%, and improved scalp skin hydration by 76.24% in adults with mild to moderate dandruff over 15 days.

  Cureus, 2024

• The combination of Thermus thermophilus and Bacillus subtilis mixed-culture ferment extract and copper tripeptide-1 GHK-Cu reduced inflammatory cytokines, protected skin explants from UV-induced damage, and improved wrinkles and skin barrier conditions compared to individual components or controls.

  Skin Research and Technology, 2026

• Topical application of 0.1% hyaluronic acid formulations of different molecular weights led to significant improvements in skin hydration and elasticity, with low-molecular-weight formulations also significantly reducing wrinkle depth in seventy-six female subjects compared to a vehicle control.

  Journal of Drugs in Dermatology, 2011

• Topical application of hyaluronic acid in conjunction with free gingival graft significantly reduced donor site postoperative pain until day 7 compared to normal saline, with no significant differences in graft dimensions or patient satisfaction.

  Clinical Oral Investigations, 2022

• Treatment with a hyaluronic acid-containing mouth rinse or topical gel led to significant lesion reduction, pain relief, and normalization of lesion color in adult patients with minor recurrent aphthous stomatitis, with the gel formulation showing an earlier healing onset at 3 days.

  BMC Oral Health, 2019

• Topical adenosine treatment significantly increased the anagen hair growth rate and thick hair rate compared to placebo in Japanese women with female pattern hair loss over 12 months.
