Key Ingredients & Benefits:

• Niacinamide (15%):

Research & Scientific Rationale:

• Niacinamide’s Efficacy: Several studies support niacinamide’s role in reducing hyperpigmentation, improving skin elasticity, and diminishing fine lines. Its ability to regulate sebum makes it effective for acne-prone skin.
