  Journal of Controlled Release, 2025

• Daily application of a cream containing niosomes loaded with purple glutinous rice extract in 20 human volunteers for 28 days resulted in a significant decrease in melanin index and skin roughness by -14.05% and -9.95%, and increases in skin hydration and elastic recovery by +48.73% and +35.98% compared to initial values.

  International Journal of Cosmetic Science, 2020

• Topical 0.5% hyaluronic-ZnO nanogel applied twice daily reduced inflammatory-lesion counts by 58% at week four in human subjects compared to baseline without causing erythema.

  Biomedicines, 2025

• Black rice extract treatment downregulated MMP-1 and MMP-3 expression, increased type I procollagen expression, and reduced reactive oxygen species production in ultraviolet-irradiated HaCaT and human dermal fibroblast skin cells.

  International Journal of Molecular Medicine, 2018

• Black rice hydrolyzed peptides induce a dose-dependent increase in hyaluronan synthase 2 gene expression and effectively increase hyaluronan production in HaCaT keratinocytes.

  Journal of Microbiology and Biotechnology, 2007

• Nels cream achieved a similar reduction in inflammatory and noninflammatory lesion counts compared to 5% benzoyl peroxide in acne vulgaris patients, but caused significantly fewer side-effects such as peeling and dryness.

  Clinical and Experimental Dermatology, 2000

• Topically applied coated and uncoated zinc oxide nanoparticles under flexing and massage are retained in the stratum corneum with no significant penetration into the viable epidermis and no cellular toxicity in human skin.

  Nanomedicine, 2016

• 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 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 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.
