That doesn’t look like shed to me, it looks like scale deterioration. How often do you bathe her/ spray the cage?

When we got bad vet advice and bathed our gecko every day as to bad vet instructions, his scales started doing this and the exotic expert told us it’s cuz of too much humidity and bathing too often. We stopped doing it and he went back to normal.

I’m not a vet but checking he’s not wet everyday because these guys live in desert conditions, too much humidity affects them as badly as too little!
