A serum is a highly concentrated intensive care product for the face. The serum is after Facial Cleansing and before facial oil or the Creme applied. Serums are usually water-based and have a light texture. Sometimes oil-based serums are also used, but this is more of a face oil than a serum.
The molecular structure of sera is smaller than that of Creams or Facial oils and that enables a facial serum to penetrate deeply into the skin. This effect is used to place valuable nutrients in a targeted and deeply effective manner. It enables serums to address skin problems that start deep within the skin, such as breakouts, pigment spots, or loss of elasticity.
