Nicotinamide solution is widely used in skincare and dermatological treatments due to its anti-inflammatory and antioxidant properties. It helps reduce redness, blotchiness, and improves skin barrier function by boosting ceramide production. Commonly found in serums and moisturizers, it treats acne, minimizes enlarged pores, and fades hyperpigmentation. It also reduces the appearance of fine lines and protects against environmental damage. In pharmaceuticals, it supports the treatment of conditions like acne vulgaris and rosacea. Additionally, it is used in hair care products to promote scalp health and reduce hair loss by improving circulation and reducing inflammation.
