  American Journal of Clinical Dermatology, 2002

• Colloidal oat extracts diminished pro-inflammatory cytokines in vitro and colloidal oat lotion improved skin dryness, scaling, roughness, and itch intensity in healthy female subjects compared to baseline.

  Journal of Drugs in Dermatology, 2015

• A new topical panthenol-containing emollient significantly improved transepidermal water loss reduction, stratum corneum hydration, and intercellular lipid lamellae length compared with control in healthy subjects without negatively impacting bacterial viability.

  The Journal of Dermatological Treatment, 2017

• Colloidal oatmeal induced skin barrier-related gene expression in vitro and showed significant clinical improvements in skin dryness, moisturization, and barrier in 50 healthy female subjects treated with a colloidal oatmeal lotion.

  Journal of Drugs in Dermatology, 2016

• 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

• A single application of a moisturizing fluid containing hyaluronic acid 1%, glycerin 5%, and Centella asiatica stem cells extract significantly increased skin hydration by 29% and reduced transepidermal water loss at 24 hours compared to baseline and an untreated control site in twenty healthy women.

  Clinical, Cosmetic and Investigational Dermatology, 2017

• 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

• A repair cream containing Rhealba oat plantlets extract, l-ALA-l-GLU dipeptide, and hyaluronic acid provided immediate relief and was judged by doctors as good or very good in 96.8% of cases for wound healing in 2,363 patients following dermatological acts.

  Clinical, Cosmetic and Investigational Dermatology, 2018

• Topically applied Avena sativa and Avena Rhealba oatmeal extracts significantly reduced skin irritation parameters including a* parameter increase and blood flow increase compared to vehicle in 12 healthy individuals subjected to the sodium lauryl sulfate irritation model.

  Skin Pharmacology and Applied Skin Physiology, 2002

• Colloidal oat increased the growth rate, metabolism, and lactic acid production of Staphylococcus epidermidis compared to Staphylococcus aureus in vitro, matching clinical increases in lactic acid on dry skin after 6 weeks of lotion use.

  Clinical, Cosmetic and Investigational Dermatology, 2021

• A Dunaliella salina extract significantly reduced skin glycation scores, histamine sensitivity, wrinkle counts, and spots compared to placebo under intense solar exposure.

  Marine Drugs, 2022

• Phytoene- and phytofluene-rich tomato and Dunaliella salina extracts show no significant cytotoxic, genotoxic, irritant, or sensitizing potential, supporting their safe human topical use.

  Journal of Toxicology, 2018

• Curcumin-loaded polyglutamic acid and gum arabic electrospun nanofibers accelerated wound healing, increased TGF-beta1 and VEGF expression, reduced inflammatory factors, and enhanced re-epithelialization and tissue regeneration in a mouse model with acute full-thickness skin defects.

  International Journal of Biological Macromolecules, 2024

• Polyglutamic acid and polylysine composite hydrogels promote wound repair and hemostasis through high water absorption, bioadhesion, calcium ion-mediated coagulation factor activation, and inherent antibacterial properties in a deep skin defect model.
