Serums, treatment liquids (essence) and ampoules contain active ingredients that are absorbed deep into the skin and care for the skin from the inside.

Apply essence after toner, before an ampoule or a serum. Serums and ampoules are added after toner or essence, if such is part of your skin care routine. Serums and ampoules are always added before moisturizer.

If you use several different serums and ampoules in your routine, add the products starting from the most liquid consistency and end with product with thickest consistency.
