Sudden rashes

I personally like Suubalm lotion (formulated by national skin centre), can buy from watson/guardian etc. It has menthol in it, so there is a cooling effect when I apply to reduce the itch sensation, and yet moisturising at the same time. I'm always itchy all over especially at night, so this is my personal life saver. If moisturisers can't solve your problem, can consider seeing a GP to get a mild steroid cream. Works wonders. Good luck and hope you find relief soon!❤
