4. Hair Spray

You might have come across this clever “trick” that says hair spray can help in setting makeup just as it does setting hair, but its not exactly as clever as it sounds. Hair spray contains various chemicals that are not harmful to the hair, but when it comes to the skin, that’s a whole other story.

The main ingredient in hair spray that can be detrimental to skin, though, is alcohol. This sneaky ingredient can irritate skin and cause inflammation or swelling. It will also dry the skin out and make you look a lot older than you are. Surely, no one wants that!
