- 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/))
- Grapeseed oil-loaded dermocosmetic nanoemulgel applied on the cheeks of healthy volunteers significantly reduced skin melanin, erythema, sebum production, and pores while increasing moisture and elasticity compared to a placebo.

([Phytotherapy Research, 2011](https://pubmed.ncbi.nlm.nih.gov/21305631/))
