before putting a new product on your sensitive skin do the following: every day for five days apply a small amount behind an ear and leave it on overnight. if your skin does not become irritated follow the same procedure this time applying the product on an area alongside an eye. if you continue to be irritation free the product should be safe for you to apply on any area(s) of your face.
with an unfamiliar skin care product how should i test for a sensitive skin reaction?
