Niacinamide is employed in dermatology because of its anti-inflammatory and free radical scavenging properties. Dermatoses where niacinamide is useful include bullous pemphigoid, Hartnup’s disease, granuloma annulare and necrobiosis lipoidica. Besides, topical niacinamide has shown to be effective as an adjuvant drug for acne, rosacea and pigmentary disorders.
