Your hands tell you what the session did to them.
After climbing, check your fingertips, pads and calluses. Look for raised edges, rough areas, splits and spots that feel unusually thin or sensitive.
Not every rough area needs to be removed. Callus is useful. It protects the skin underneath and helps your hands tolerate repeated contact with holds.
The goal is strong, even skin without loose edges that can catch during your next session.
If an edge is raised but the skin underneath is healthy, light maintenance can help level it. If the area is painful, raw, split or bleeding, leave it alone and allow it to recover.
