The skin on your face is the thinnest skin on your body. In fact, the thinnest skin you have, which is found around your eyes, is 80 times thinner than the thickest skin on your body (hint: you stand on it). Yet your face gets exposed to more skincare and cosmetic products than any other part of the body. Washes, moisturisers, toners, peels, lipstick, foundation, blush and eyeshadow, the list is endless. So, it’s not surprising that skin allergies often appear first on the face.
