- 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](https://pubmed.ncbi.nlm.nih.gov/34439563/))
- Topical gel containing chitosan, 0.2% chlorhexidine, allantoin and dexpanthenol did not improve postoperative comfort regarding swelling and pain, but improved the wound's aesthetic appearance following impacted lower third molar extraction compared to no gel. ([Medicina Oral, Patologia Oral Y Cirugia Bucal, 2016](https://pubmed.ncbi.nlm.nih.gov/27475700/))

- 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.
