What is the role of niacinamide in acne treatment?

Niacinamide, also known as vitamin B3, plays a significant role in acne treatment due to its multifaceted benefits for the skin. One of its primary functions is to reduce inflammation, which is crucial in managing acne breakouts. Inflammatory processes are often a component of acne, and niacinamide helps to soothe the skin and reduce redness and irritation associated with it.

Additionally, niacinamide strengthens the skin barrier, which is vital for maintaining proper hydration and protecting the skin from environmental aggressors. A healthy skin barrier can help minimize the occurrence of acne by preventing the retention of excess sebum and the entry of microorganisms that can lead to breakouts.

While niacinamide does offer some hydrating properties, its role in reducing inflammation and supporting the skin barrier are what make it particularly effective in treating acne. It is not limited to being an exfoliant, a moisturizing agent, or providing hydration without acne benefits; its multifaceted approach directly addresses the underlying factors involved in acne development.
