I've noticed when climbing and bouldering I have a tendency to get occasional flappers on my palm. A flapper being a callus or blister that has peeled back and hangs on like a flap of skin. I trim the skin away as close to the origin as possible to avoid having it snag on anything, it then tends to take a couple weeks to heal completely, though by the first week it's usually healed enough to climb without major inconvenience.
Are there any tricks other people have to healing a flapper quicker?
