- Is there an age where IPL will not work in tightening my neck?

There is not an exact age where IPL will work or not. It depends more on the "age" of your skin. As you get older, your skin loses its elasticity. But the age that you lose elasticity occurs at different times in different patients. This usually depends on your genetics. But in general, as you get into your 50's, the skin has less recoil because of loss of elasticity. IPL for skin tightening works best when there is good collagen/good elasticity in the skin. Therefore, if you are in your 50's or greater, the lack of collagen may make IPL less effective in tightening your neck skin.
