Panthenol
While panthenol is not naturally present in the body, it can be absorbed and converted into the active form of vitamin B5, which plays a vital role in various physiological functions. While niacinamide and panthenol belong to the same vitamin B group, they cater to different skin concerns and functions. Niacinamide focuses on brightening, anti-aging, oil regulation, and anti-inflammatory benefits, while panthenol specializes in hydration, soothing, repairing, and strengthening the skin barrier.
