Are there any side effects of using lip plumping device for improving looks, i wanted to check this before considering buying one thanks?

Lip Plumping: Over-the-counter lip plumper products use an irritant that causes the lips to swell temporarily, giving a fuller, pouty appearance. But while you want that "bee stung" look, you don't want the inflammatory reaction of a real bee sting. Some of the ingredients used as an irritant include cinnamon, menthol or mint, ginger, niacin--even chili pepper. These products may cause pain, and a severe rash.

Temporary: These devices that cause swelling create a situation of increased blood and fluid into the lip which will last at best a few hours and may cause bruises and irritation. If you really want fuller lips the longer lasting treatment is hyaluronic acid fillers ( juvederm , restylane, (dermal fillers) ) in the proper hands they are safe, effective and will laser several months
