Looking after your climbing skin

The limit nobody trains for

Most climbers train fingers, core and technique, and then get stopped by their skin. You are strong enough for the move, but the tips have gone shiny and hot, the edge feels like it is buttered, and every attempt makes it worse. Skin is the one part of the system that cannot be muscled through, and in summer it takes the most punishment of the year.

Heat is the problem. Warm hands sweat, sweat softens the skin, and soft skin tears or greases off holds instead of sticking. On rock the sun bakes the stone until the friction goes and the edges feel sharper than they did at dawn. Learn to manage your hands and you get more good attempts out of every session, indoors and out. Ignore them and you lose days to a single flapper.

Know your own hands first

There is no single skin routine, because there are roughly two kinds of climbing skin and they want opposite things.

Sweaty, soft skin greases off holds when it is warm and needs drying out. If your tips go damp and slick after a few minutes, you want more chalk, more brushing, and cooler conditions. Antihydral and similar drying agents help the worst cases, used sparingly, because too much swings you the other way into cracked, glassy skin.

Dry, splitty skin does the opposite. It looks tough but it cracks along the creases and splits under a sharp crimp. This type wants moisture back in overnight and files that keep the calluses flat rather than letting them build into ridges that peel. Work out which camp you are in before you copy anyone else's setup, because the fix for one makes the other worse.

In the session

The best skin care happens while you climb, not after. A few habits pay off every time.

• Chalk to dry, not to coat. Chalk manages moisture, it does not add grip on its own. A light, even layer that dries the tips beats a thick paste that just fills the texture of the hold. Rechalk when your hands warm up, and blow the excess off.
• Brush the holds. A brushed hold is a grippier hold, and it means you press less hard to stay on, which saves skin. Keep a brush on your harness or in your bag and use it on anything polished or chalked up.
• Stop before the tear, not after. Skin gives you warning. When a tip goes hot, shiny and tender, that is the last honest attempt, not the fifth. One more go on glassy skin is how a manageable session becomes a week off. Walk away with something in the tank.
• Mind the sun. Outdoors, chase shade and cooler hours. The same problem at ten in the morning can feel a full grade easier at eight, purely because the rock and your hands are cool.

Files, not just chalk

Between sessions, the tool that matters most is a skin file or a piece of fine sandpaper. The goal is simple: keep the surface of your tips smooth and the calluses flat and level with the skin around them.

A proud callus, sitting up higher than the skin beside it, is a flapper waiting to happen. It catches on an edge and peels a chunk away. Run a file gently over any raised, hard spots until they sit flush, then leave the healthy skin alone. You are levelling the ground, not sanding down to raw skin. Do it when your hands are dry, a little each time, rather than a big session once a month.

Dealing with tears and flappers

Everyone gets them. What matters is what you do next.

If a flap of skin is still attached and mostly clean, do not rip it off in the moment. Trim it back to the edge of the wound with clean nail scissors once you are home, so nothing catches and reopens it. A ragged flap left hanging tears wider on the next hold.

Clean the raw patch, let it dry, and keep it uncovered when you are not climbing so it can harden over. Some climbers cover a fresh split with a dab of superglue or a proper skin glue to get through the last problems of a session, which is fine as a short-term patch, but it is not healing, it is buying time. The real repair happens overnight and over rest days.

The overnight repair

Skin rebuilds when you are not using it, and you can help it. If you are the dry, splitty type, a climbing salve or a plain unscented moisturiser before bed puts water back into the tips so they flex instead of cracking. If you are the sweaty type, go easy on the cream and let the skin firm up on its own.

Sleep, water and food do more than any product. Well-hydrated skin is more elastic and tears less, and a body that is recovering well grows callus faster. None of this is exotic. It is the same recovery that helps your fingers and your head, pointed at the one tissue climbers forget to look after.

Play the long game

Good skin is not a single fix, it is a running account. You make small deposits every day, a light file here, a moisturise there, a session ended one attempt early, and you draw on them when a project is finally in condition and you want ten clean goes rather than three. The climbers who send in summer are rarely the ones with the toughest hands. They are the ones who read their skin honestly and stopped fighting it. Learn your own tips, keep them level and cared for, and they will hold up when it counts.
