REALLY dry sky from breastfeeding?

Hey all. New here so I don’t know if this is topic for here… but Ive been breastfeeding for seven years… back to back kids ages 7, 4 and 2.5. Honestly I have not been hydrating the way I should have. I’ve gotten better but I feel like the skin on my arms and legs is just rough looking.. I am 38 in july so maybe it’s just age too. I’m working on weaning now but will my skin get better after stopping or is this just it now? 😭
