Human Foreskins
We know, you think we’re pulling your leg (or something else), but we’re absolutely serious. Human foreskins have been used for many years in the medical industry in order to cultivate new skin growth to save burn victims from having skin grafts. Now, a very similar method has been put to use by the cosmetic industry. The foreskins are used to make fibroblasts, a type of cell that helps in wound healing. Then it can be applied to those fancy anti-aging products to keep you young. Any price right?
