Comparative study of niacinamide cream and gel

Abstract

This thesis explores the use of niacinamide, a form of vitamin B3, in skincare. Niacinamide is known for its benefits in improving skin texture, reducing inflammation, and supporting the skin barrier. Two different topical products containing niacinamide cream and gel were prepared and compared. The goal was to see how each one affects the skin and how well niacinamide can be absorbed. Both products were found to be safe and effective, but the gel allowed better delivery of niacinamide into the skin. These results support the use of niacinamide in modern cosmetic and dermatological formulations.
