The process driving skin regeneration is mitosis. In healthy skin, mitosis occurs in the basal layer (stratum basale) where keratinocyte stem cells divide to produce new cells. These new cells move upward through the epidermal layers, mature, and eventually become the outer, shed corneocytes. This continuous cell division keeps the skin renewed and repaired after injury or normal wear. The other options describe either a general idea of turnover (cell renewal), a structure (basal membrane), or a characteristic (thickness variation) rather than the actual division mechanism.
