Between the Fingers
The skin between the fingers — normally called webbing — is a special “niche” to pick at 
. Compulsive skin-pickers pick at this part of the hands/fingers, especially if the skin there is callused or tough and can be picked without causing pain.
Fun Facts about the skin between the fingers:
- In Traditional Chinese medicine, an important acupressure point called the “Hoku Point” lies in the thumb webbing between the thumb and forefinger
- A rare birth defect called Syndactyly — where two or more finger digits are fused together — creates a strange duck-foot like appearance in the finger webbing
- Spider Man shoots spider webs out of his “finger webs”
