Detailed answer

Niacinamide is a potent ingredient that can help fade acne scars. It works by reducing inflammation, improving skin texture, and promoting collagen production. To fade acne scars with niacinamide, apply a skincare product containing niacinamide to the affected area daily. Be consistent and patient, as it may take several weeks or months to see noticeable results. Additionally, always remember to use sunscreen during the day to protect your skin from further damage and to enhance the effectiveness of niacinamide.
