Should I Use Niacinamide Or Hyaluronic Acid First?
Choosing whether to apply niacinamide before hyaluronic acid depends on skin type, concerns, and product formulas. In many routines niacinamide can be layered first to prep the skin, but if you have very dry or sensitive skin you might benefit from hyaluronic acid first. Consider your skin’s barrier, the concentration of each actives, and any other products you use before deciding.
