I know that what I use works really well for me, and I have super duper sensitive skin sometimes :c I'm an interning manager at a farmers market where I live, and there's a lady that comes that makes soap and all kinds of stuff out of natural things like beeswax, coconut oil, shea butter etc. Her stuff IS scented, but it's just veeery mild. I like it c: it's really thick and smooth..which normally I don't like, but it makes me feel cleaner than Dove & stuff. Best part is, I hardly ever have to use lotion afterwards cause it's really moisturizing :P
Try using a product for sensitive skin. If that doesn't help or eliminate the problem, contact your physician. You may also want to try changing your diet and exercise habits. Trying a sauna may also help.
