Serums are lightweight skincare products that contain a high concentration of active ingredients. They are designed to penetrate deeply into the skin, delivering targeted benefits such as hydration, brightening, or anti-aging effects. Unlike creams, serums have a thinner consistency, making them ideal for layering under moisturizers or other treatments. Many people use serums as part of their daily skincare routine to address specific concerns like acne, wrinkles, or dark spots. Popular ingredients found in serums include hyaluronic acid for hydration, vitamin C for brightening, and retinol for anti-aging. Incorporating a serum can enhance the overall effectiveness of your skincare regimen.
