At Kiehl’s we recommend the following order for applying skincare products:
Face Cleanser
Toner
Eye Treatment
Facial Essence and/or Serum
Face Oil
Moisturizer
Sunscreen (during the day!)
If you are using a rinse-off face mask, apply after cleansing and follow with the rest of your skincare routine. If you are applying an overnight face mask, use it after or in place of your moisturizer according to the formula’s directions.
