No, humans do not have 50 layers of skin. The human skin is comprised of three main layers: the epidermis, dermis, and hypodermis. While the epidermis, the outermost layer, can be further divided into sub-layers, the overall number of skin layers remains at three.
The statement about having more than 50 moles increasing the chances of developing melanoma is likely referring to the number of moles on the skin, not the number of layers. This is because moles are formed by clusters of melanocytes, the cells responsible for skin pigmentation, and their presence can indicate a predisposition to certain skin cancers.
