cleavage lines

Cleavage lines are natural patterns or directions in the skin's surface, where the skin tends to split or tear more easily when stretched or injured. They reflect the underlying structure of collagen and elastin fibers in the skin. Surgeons consider these lines when making incisions because cuts along them tend to heal better, create less scarring, and are less noticeable. These lines are particularly important in cosmetic and surgical procedures to optimize healing and aesthetic outcomes. Understanding cleavage lines helps in minimizing tissue damage and improving recovery post-surgery.
