The science behind bizarre skincare rituals, such as the "K-Beauty" craze in Seoul, South Korea, involves injecting tiny fragments of DNA from salmon sperm into the dermis, the skin's thick middle layer. This concept originates from regenerative medicine and wound healing, where DNA fragments from fish have been highlighted for their potential to stimulate tissue repair in people with facial scars from combat injuries. However, scientific data is sparse, with studies suggesting that these treatments may help reduce the appearance of fine lines and improve skin hydration, plumpness, texture and wrinkles. The popularity of these treatments has also risen alongside other bizarre skIncare treatments, which include facemasks made of bird droppings and blood-sucking vampire facials. However it's important not just to use purified nighting droppings for cosmetic purposes, but to use them as a tool for skin rejuvenation.
