Hospitals routinely sell foreskins collected from newborn circumcisions to companies for thousands of dollars. These companies use them for 1) making expensive skin cream, 2) cosmetic testing, and 3) skin grafts for burn victims.

So with those foreskins, or more accurately, the fibroblasts from the cells of the foreskin, collagen can be lab-created, and where do you put collagen? On your face! Penis wrinkle cream, anyone? Oprah’s beloved SkinMedica product? Yup! Foreskins! One foreskin can be used for decades to grow thousands of fibroblasts.
