If i have sensitive skin and previous contact or atopic dermatitis, can i use a depilatory on the face and bikini areas?

Try testing first: I would recommend testing the cream in a small discrete area first. We call it patch testing. Take a small amount of the cream and put it under duct tape or a bandage on the upper inner arm or leg where no one will see. Leave it on for 48 hrs - reapply after shower, and then wait another few days to make sure you do not have a delayed response. If no redness or itching it should be safe to use.
