Used in skincare formulations for its vasodilating properties, n-Butyl nicotinate helps improve microcirculation when applied topically. It is commonly included in anti-cellulite creams and warming lotions, where it creates a mild flushing and heating sensation, promoting the breakdown of fat deposits and enhancing absorption of other active ingredients. Due to its ability to stimulate blood flow, it is also found in products designed for muscle and joint pain relief. In addition, it may support skin rejuvenation by increasing nutrient delivery to the skin cells.
