Face serum is a specific cosmetic product used for intensive and targeted skin care treatments. It has a liquid form and is usually packaged in a glass bottle with a pipette, which facilitates the application and use of the product. Serums are enriched with a higher concentration of nutritious and hydrating ingredients, compared to creams, so they are therefore more efficient in care treatments and the desired results are visible faster. They are applied in small quantities, just 3-4 drops of serum are enough for the whole face. As a rule, they are used in the morning and/or evening and applied to clean skin of the face and neck and gently tapped in with fingers.
