This stuff rocks! I have very thin skin, due to medication, so any calluses I build up get ripped apart very easily. After a nice jam I have cracks in my fingertips. A little drop of this stuff and they’re whole again, ready for more shredding. My son is just starting guitar and when his fingers hurt, I put this on and he plays on laughing. And the best part, it actually helps your fingers create calluses too, so after a while you don’t have to use it anymore! Recommend!
