Why is the skin peeling loff and reddern and swollen?

hmm, in my experience, the skin wouldnt peel off and swell without anything triggering it. maybe it was something you ate, maybe you were allergic to something and you werent really aware of it. or maybe you applied something on your skin which made it that way. if you realize that your skin is sensitive, dont use products right away. try to test them first, its what we call "skin patch test". you apply the product first on just a small area on your skin and you observe if that area has somenegative reactions after the product has been applied. if after 24 hours, there is no violent or harsh reaction that the product has on your skin, then maybe it is safe to use that product on your whole face/body. :) but to be safe, try to buy those products which have the label "hypoallergenic".
