• 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 topical preparation containing urea, sunflower oil, evening primrose oil, wheat germ oil, and sodium pyruvate led to clinical improvement after a month in diverse hyperkeratotic skin conditions except pityriasis lichenoides.

  Medicina Cutanea Ibero-latino-americana, 1986

• Topical application of linseed, evening primrose, and olive oil emulsions accelerated wound closure in rats with excision wounds compared to untreated controls, though via different mechanisms.

  Drug Delivery and Translational Research, 2019

• Topical application of 10% evening primrose oil (EPO) and Lioxasol creams resulted in increased cell proliferative activity in the skin of female pigs compared to untreated skin, with EPO producing a more pronounced increase in basal layer labelling index and Lioxasol causing a more immediate increase in papillary dermis labelled cells.

  Cell Proliferation, 1997

• 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

• Enzyme-modified ginseng extract cream significantly reduced the global photo-damage score and various roughness measures including total roughness, smoothness depth, and arithmetic roughness average compared to placebo in 23 human subjects.

  Rejuvenation Research, 2015

• A red ginseng hydrogel formulation with 1,2-hexanediol promoted selective growth of Staphylococcus epidermidis and decreased Cutibacterium acnes in 20 female subjects.

  Journal of Ginseng Research, 2022

• A 1% fermented black ginseng cream significantly reduced eye wrinkles and brightened skin color in twenty-three human subjects compared to control cream and baseline.

Why other moisturizers fit skin with dark spots better

• Niacinamide significantly decreased hyperpigmentation and increased skin lightness compared with vehicle alone after 4 weeks of use in women by inhibiting melanosome transfer.

  The British Journal of Dermatology, 2002

• Topical oxidized glutathione significantly decreases the skin melanin index and improves moisture content, smoothness, wrinkle formation, and elasticity compared to placebo in healthy women.

  Clinical, Cosmetic and Investigational Dermatology, 2014

• Topical application of Lactobacillus plantarum-GMNL6 enhanced collagen synthesis and SPTSSA gene expression while reducing melanin synthesis, Staphylococcus aureus biofilm, and Cutibacterium acnes proliferation, leading to clinical improvements in skin moisture, color, spots, wrinkles, UV spots, and porphyrins in human volunteers.
