Questions and answers

What the research says

• 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

• A multi-component dissolving microneedle patch loaded with glabridin, 3-O-ethyl-L-ascorbic acid, and tranexamic acid effectively reduced chloasma and age spots while demonstrating safety in clinical evaluation, alongside significant antioxidant, anti-tyrosinase, and melanin-reduction effects in vitro and in vivo.

  Polymers, 2023

• Dissolving microneedles loaded with 3-O-ethyl ascorbic acid and acetyl hexapeptide-8 achieved higher cumulative transdermal delivery than aqueous solutions and significantly reduced photoaging signs while restoring oxidative balance in a UV/D-galactose-induced mouse model.

  International Journal of Biological Macromolecules, 2026

• Topical application of an aqueous gel containing 0.1% w/w naringenin demonstrated in vitro safety, significantly reduced UV-induced stratum corneum lipid peroxidation, and showed in vivo anti-inflammatory efficacy against methyl nicotinate-induced inflammation in human participants compared to a blank gel and untreated area, while chlorogenic acid, apigenin, and kaempferol displayed pro-oxidant profiles.

  Frontiers in Chemistry, 2024

• Topical application of a naringenin-containing formulation protected hairless mice from ultraviolet B-induced skin damage by inhibiting edema, cytokine production, superoxide anion, and lipid hydroperoxides while maintaining antioxidant enzymes and glutathione levels.

  PloS One, 2016

• Encapsulating naringenin, nordihydroguaiaretic acid (NDGA), and kaempferol into nanostructured lipid carriers provided prolonged release, stability, and antioxidant protection against oxidative stress in human keratinocytes, with an NDGA and kaempferol mixture showing synergistic antioxidant effects.

  Pharmaceutics, 2021

• 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.
