Definitely have a go of the CeraVe SA smoothing cream. A little goes a long way and it will work miracles for dry skin. You can use it all over your body too. I’ve got a big pot of the stuff and it lasts ages. They also have moisturisers with SPF which you can use together with the SA cream. The foaming oil cleanser or the hydrating cleanser would be great for you.
“You can’t make a silk purse from sows ear” means you can’t make something nice from rubbish. “You can’t get blood from a stone” means attempting something difficult, if not impossible and futile”. E.g. “trying to get my kids to tell me about their school day is like trying to get blood from a stone.” It doesn’t matter how hard I try I get nothing.
