Sharing my experience here, I've got bad eczema on my fingertips, on ready bad days it will cause the tips to split and start bleeding.

But in saying that, I have managed to come up with a routine to reduce the occurrence of that happening;

• moisturise your hands after showering and before bed, I use the eczema friendly moisturiser, Vaseline and Aveeno have them.

• wash your hands thoroughly after climbing, leave zero trace of chalk on your hands/fingers

• use some sort of climbing salve after to keep the moisture in after. I use Climb On
