MAINTAIN THEM BEFORE THEY TEAR.

Calluses protect your hands—until excess buildup gives them something to catch on. Consistent filing keeps them smooth and at the right thickness, so they can keep doing their job.

Before: Hand opened up to show thick calluses build up as well and many ripped callus on the palms and fingers.

BEFORE

AFTER: A hand that was once ripped and callused, now smooth and well maintained after using the SandBar Callus file and Salve.

CALLUSES NEED RECOVERY JUST LIKE THE REST OF YOUR BODY

Filing handles the buildup. Recovery keeps calluses from getting dry and brittle. Apply Callus Recovery Salve after filing or at night so calluses stay strong and protective.

Frequently asked questions

Have questions? We have you covered
Are calluses bad for your hands?
No, they're your body's built-in grip protection. The problem starts when they get too thick or uneven and tear. Filing and conditioning fix that without eliminating the callus itself.
What causes hand calluses?
Repeated gripping, friction, and pinching cause your skin to thicken at the points of greatest stress. That's your body's way of protecting itself.
What's a callus rock or callus cube, and do I need one?
Those build calluses on purpose for grip training. Recovery Salve isn't a builder, since it's the conditioner that comes after, keeping what you've built from tearing.
How do I treat a thick callus on my hand?
If your callus has become too thick, gradually file away the excess—but don't remove it completely. Calluses protect your hands. The goal is to maintain the optimal thickness with consistent filing and Recovery Salve, not to start over every time.
How is this different from a callus file or callus ball?
Filing manages buildup, while a callus ball builds it. Recovery Salve is the conditioning step after, keeping what you've built from tearing.
