A face serum is a lightweight, fast-absorbing skincare product formulated with concentrated active ingredients designed to target specific skin concerns. Serums can help improve hydration, brighten the complexion, reduce the appearance of fine lines and wrinkles, minimize dark spots, and enhance overall skin texture. Common ingredients found in face serums include hyaluronic acid for moisture, vitamin C for brightening, niacinamide for skin barrier support, and retinol for anti-aging benefits. Applied after cleansing and before moisturizing, face serums deliver potent nutrients deep into the skin, promoting a healthier, smoother, and more radiant appearance.
