Detailed answer

Serums are highly concentrated products that can deliver targeted active ingredients to your skin. To use a serum effectively, cleanse your face as usual and follow with a toner. Once your skin is prepped and clean, apply a few drops of serum to your fingertips and gently massage it into your skin. Allow the serum to fully absorb before proceeding with your moisturizer. Serums are designed to penetrate deep into the skin and deliver powerful ingredients, so they work best when applied directly to clean, toned skin. Applying a moisturizer afterwards helps to lock in the serum and provide hydration to your skin.
