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

• Topical hyaluronic acid filler serum combined with Botulinum toxin type A lengthened the duration of the toxin's effect in reducing wrinkles compared to Botulinum toxin type A alone.

  Dermatologic Therapy, 2022

• Chemical sunscreens containing avobenzone, octocrylene, homosalate, and octisalate showed no to minimal risks of dermal irritation, sensitization, photo-allergy, and photo-irritation in human subjects.

  Journal of Drugs in Dermatology, 2025

• Sunscreen products formulated with 1-6% oxybenzone yielded a mean rate of dermal irritation or sensitization of 0.26% and a contact allergy rate of 0.07% in participants from the general population.

  Photodermatology, Photoimmunology & Photomedicine, 2008

• Topical application of sunscreen agents in human volunteers resulted in significant skin penetration of all agents and systemic absorption of oxybenzone and its metabolites.

  Journal of Chromatography. B, Analytical Technologies in the Biomedical and Life Sciences, 2004

• Combined use of the insect repellent DEET and the sunscreen oxybenzone significantly enhanced percutaneous penetration percentages by 36% to 108% and increased their in vivo AUCP/MRT compared to separate applications.

  Toxicology and Applied Pharmacology, 2007

• 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

• Encapsulation of ethylhexyl methoxycinnamate and butyl methoxydibenzoylmethane in lipid microparticles significantly reduced their in vivo human skin penetration compared to nonencapsulated filters.

  Skin Pharmacology and Physiology, 2011

• Microencapsulation of the BMDBM/HP-beta-CD complex in lipid microparticles significantly decreased the percutaneous penetration of the UV filter into the stratum corneum of human volunteers compared to the non-encapsulated sunscreen agent.

  Journal of Pharmaceutical and Biomedical Analysis, 2011

• Following human skin application of an O/W emulsion containing 2% BMDBM loaded in lipospheres, 15% of the sunscreen accumulated in the uppermost layers of the stratum corneum without remarkably modifying skin permeation compared to unencapsulated sunscreen.

  Skin Pharmacology and Physiology, 2008

• Simulated real-life dermal sunscreen exposure in twenty human volunteers leads to the systemic bioavailability and urinary excretion of the UV filter 2-ethylhexyl salicylate and its metabolite, reaching concentration peaks at 7 to 8 hours with 70-80% of overall excretion within 24 hours.

  Archives of Toxicology, 2019

• The application of a sunscreen formulation containing ethylhexyl methoxycinnamate, ethylhexyl salicylate, methyl anthranilate, and octocrylene does not significantly affect critical acne-related species such as Cutibacterium acnes and Staphylococcus epidermidis, refuting the induction of facial dysbiosis in men.

  Archives of Dermatological Research, 2024

• Controlled single dermal exposure to an EHS-containing sunscreen in three volunteers resulted in delayed systemic resorption with elimination half-lives between 6.6 and 9.7 hours, where the parent compound EHS occurred as the dominant urinary parameter.

  Archives of Toxicology, 2024

• 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.
