Using a serum in your skincare routine helps target specific skin concerns because it contains a high concentration of active ingredients. Hyaluronic Acid deeply hydrates the skin, Vitamin C brightens the complexion and reduces dark spots, Niacinamide controls excess oil and minimizes pores, Retinol helps reduce fine lines, and Salicylic Acid helps prevent acne. Apply serum after cleansing and before moisturizing for the best results. Always choose a serum based on your skin type and wear sunscreen during the day. Consistent use of the right serum can improve your skin’s overall health and appearance over time.
