What should sensitive skin watch for?

COSRX markets the cleanser for sensitive skin, but test it before using it across your face. Skincare ingredients can trigger allergic contact dermatitis, an allergic skin reaction that causes redness, itching and swelling. Botanical ingredients also deserve attention if fragrance causes reactions: a plant ingredient is not automatically a fragrance safe choice.12

How to test the cleanser first

1. 1Choose a spot about the size of a quarter on the underside of your arm or the bend of your elbow.
2. 2Apply your usual amount twice daily for seven to ten days.
3. 3For a cleanser test, leave the product on for five minutes or as long as its instructions specify, then wash it off.
4. 4If no redness, itching or swelling develops during the test period, start using the cleanser on your face.

If a reaction develops, gently wash the cleanser off and do not use it again. A cool compress or petroleum jelly can help relieve the skin. See a dermatologist if the reaction is severe and those measures do not relieve it. If the trigger is unclear, medical patch testing can help identify the ingredient to avoid.2

How do you use it?

COSRX directs morning and night use after removing makeup. Wet your hands and face, foam the cleanser in your hands, gently massage it onto your face while avoiding the eyes and mouth, then rinse with warm water.1

Cleansing comes before serums and moisturizer, rather than becoming a subplot halfway through the routine.34
