• Topical post-laser application of human adipocyte-derived mesenchymal stem cell media combined with niacinamide significantly improved wrinkle index, melanin index, patient satisfaction, and investigator esthetic improvement scores compared to vehicle cream in patients with aging skin.

  Journal of Cosmetic Dermatology, 2021

• Topical treatment of nicotinamide, alone or in combination with other active ingredients, reduces the progression of skin aging and hyperpigmentation in clinical trials while being well tolerated.

  Antioxidants, 2021

• Emulgels containing Perilla frutescens seed oil, Moringa oleifera seed oil, and mixed seed oil microemulsions exhibit good stability, lack of cytotoxicity in PBMC, and no skin irritation or allergic reactions in human subjects.

  Polymers, 2022

• Oral and dermal administration of Uvinul A plus resulted in three major urinary metabolites accounting for 52% of the oral dose, with a very low estimated daily systemic exposure of 8.1-9.3 μg/d in volunteers not intentionally exposed.

  International Journal of Hygiene and Environmental Health, 2020

• Microencapsulation of ethylhexyl triazone in lipid microparticles significantly reduced its in vivo human stratum corneum penetration by 45.7% compared to the nonencapsulated sunscreen.

  Skin Pharmacology and Physiology, 2019

• A topical sunscreen containing octyl triazone, phenylbenzimidazole sulfonic acid, and methylbenzylidene camphor prevented UVB-induced suppression of intercellular adhesion molecule-1 expression and mixed-lymphocyte reaction in epidermal cell cultures compared to control sunscreens with comparable SPF lacking octyl triazone.

  Toxicology in Vitro, 1994

• Scanning Raman microscopy combined with tape stripping on three volunteers demonstrated that 91.1% of applied MBBT sunscreen was recovered, with 30.2% on the skin surface, 42.5% in the upper stratum corneum, and surface concentrations differing up to 300-fold between skin folds and ridges.

  International Journal of Cosmetic Science, 2011

• A topical xanthan gum nanogel containing gamma-oryzanol-loaded nanostructured lipid carriers and nanosized TiO2 and MBBT filters demonstrated high photoprotection with an SPF of 34 and no skin irritation or sensitization in a rat model.

  Pharmaceuticals, 2023

• Topical nicotinamide prevented solar-simulated UV-induced immunosuppression in healthy volunteers, and men experienced immunosuppression at solar-simulated UV doses three times lower than those required for women.

  The Journal of Investigative Dermatology, 2008

• Topical 5% niacinamide applied twice daily for 12 weeks reduced fine lines and wrinkles, hyperpigmented spots, red blotchiness, and skin sallowness, and improved skin elasticity compared to vehicle control in 50 female white subjects with facial photoaging.

  Dermatologic Surgery, 2005

• Topical 2% niacinamide significantly decreased sebum excretion rate in Japanese individuals and casual sebum levels in Caucasian individuals compared to placebo or baseline.
