Ever since I started processing my own negatives, I have noticed that my fingertips are really dry, like the skin is leathery and sensation is minimal, although blood flow seems to be reaching the tips.

I don't know if this is the result of not wearing gloves in winter or from getting fixer or developer on them. A little chemical might have touched my hands the first time but I could swear that during all the rest of the developing sessions I have worn thick rubber dishwashing gloves.

Any ideas?
