Itchy

Hi girls, so I have a problem. I have very sensitive skin and my legs are itchy all the time. I use lotion for sensitive skin and another lotion for when my legs are itchy. It calms down for the moment but next thing I know I’m itchy all over again. It normally just happens in my legs but sometimes it’s all over my body. Do any of you have advice or tips on what to do? Or what lotions I should be buying?
