Now it’s very easy to source plastic surgery leftovers (i.e. under eye bags, face lifts etc.) which would contain fibroblasts, so not sure what special benefits would be in foreskin fibroblasts over facial fibroblasts.

In most parts of the United States, circumcision is the complete norm at hospitals for newborns, so it might have been easier to obtain foreskins rather than plastic surgery leftovers.
