Do your skincare serums really work? What tests reveal about Vitamin C, Retinol and Niacinamide

Skincare serums with Vitamin C, Retinol, and Niacinamide can be effective, but their benefits depend on formulation, stability, and proper use. Vitamin C brightens skin and reduces pigmentation but is unstable, requiring airtight, opaque packaging or stable derivatives. Retinol boosts collagen and smooths fine lines but can irritate, so it should be introduced gradually, usually at night, with daytime sunscreen. Niacinamide reduces redness and strengthens the skin barrier and is generally well-tolerated. For best results, choose products with stable, research-backed ingredients and maintain consistent, suitable usage.
