Hi there. Advice needed

My 3 yr old female Dwarf Retic never had problems shedding; she'd always slough off her old skin in one piece. Her last shed was roughly 3 weeks ago and she is beginning to "get darker than usual" but isn't exactly in "shed phase".

Last night however, I noticed tiny "scale flakes" on her water bowl; at first I though they were mites but when I examined further, it's indeed "scale flakes" (yes, they're THAT tiny).

I gave her a good dip in lukewarm water last night for half an hour and when I gently rubbed her continously, more of the "scale flakes" came off.

I always change her substrate when I notice she'd make a mess and I occasionally bathe her in soap (usually, the ones used for washing your face) and water as I let her crawl on my bed from time to time.

Any of you guys experienced the same?

Thanks

PS: I live in Manila, where retics are considered to be "native fauna".
