• Antarctic marine algae extracts increased cell viability, protected against inflammation, and enhanced the barrier integrity of human intestinal and keratinocyte cell lines damaged by lipopolysaccharide or ultraviolet radiation.

  Marine Drugs, 2022

• The emollient V0034CR significantly reduced TEWL compared to vehicle and vehicle plus glycerol, and significantly increased corneometry scores compared to vehicle and vehicle plus petrolatum in healthy volunteers with dry skin, demonstrating combined barrier function improvement from petrolatum and hydration improvement from glycerol.

  Journal of Cosmetic Dermatology, 2020

• Ten days of treatment with a cream containing 20% glycerin significantly increased skin hydration measured by corneometer values in 17 healthy volunteers compared to a placebo cream, but showed no influence on transepidermal water loss or skin sensitivity to an irritating surfactant.

  International Journal of Cosmetic Science, 2001

• Niacinamide/glycerin body moisturizers provided better rapid and prolonged improvement of cosmetic xerosis through functional improvement of stratum corneum barrier function compared to no treatment and conventional moisturizers in female subjects.

  Journal of Drugs in Dermatology, 2012

• Treatment with cross-linked hyaluronic acid-based microneedle patches combined with acetyl hexapeptide-8 or epidermal growth factor significantly improved wrinkles and skin hydration compared to the patch alone in Korean females over 29 days.

• Argireline treatment twice daily for 4 weeks produced a significant anti-wrinkle effect with 48.9% total efficacy and decreased skin roughness in Chinese subjects compared with 0% efficacy and no decrease in roughness in the placebo group.

  American Journal of Clinical Dermatology, 2013

• Acetyl hexapeptide-3 and tripeptide-10 citrulline demonstrated antiwrinkle efficacy and decreased transepidermal water loss in twenty-four healthy volunteers compared to control groups, though synergistic effects between the two peptides remained unclear.

  Journal of Cosmetic Dermatology, 2017

• 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.
