- 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](https://pubmed.ncbi.nlm.nih.gov/12100180/))
- Capryloyl salicylic acid peel reduced fine lines, wrinkles, and hyperpigmentation comparably to glycolic acid peel in 44 female volunteers, with no statistically significant differences between the two treatments. ([Journal of Cosmetic Dermatology, 2008](https://pubmed.ncbi.nlm.nih.gov/19146601/))
- Hyaluronic acid extracts are safe and efficacious products for skin repair when used in tissue regeneration alone or in combination with herbal or Western medicine. ([Journal of Pharmacy & Pharmaceutical Sciences, 2015](https://pubmed.ncbi.nlm.nih.gov/25877441/))
- Optimized transfersomes loaded with epigallocatechin-3-gallate and hyaluronic acid increased cell viability while reducing lipid peroxidation, intracellular ROS, and MMP expression in HaCaT cells, and exhibited higher skin permeation and deposition compared to plain EGCG. ([Drug Delivery, 2017](https://pubmed.ncbi.nlm.nih.gov/28155509/))
- 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](https://pubmed.ncbi.nlm.nih.gov/33103316/))
- 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](https://pubmed.ncbi.nlm.nih.gov/17882270/))
- 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](https://pubmed.ncbi.nlm.nih.gov/16029679/))
- Balneotherapy with thermal water altered specific skin microbiota at genus and species levels in healthy female volunteers compared to tap water, which produced no significant microbiome changes. ([Life, 2023](https://pubmed.ncbi.nlm.nih.gov/36983902/))

- A 2% Sphingomonas xenophaga ferment extract cream applied twice daily for 4 weeks significantly decreased facial vascular disorder scores compared to vehicle in 86 Caucasian female subjects, alongside dose-dependent inhibition of pre-kallikrein activity in vitro.

- 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](https://pubmed.ncbi.nlm.nih.gov/34623507/))
