Keratin refers to a hard protein material that plays a critical role in protecting the cells in the outer layer of the skin, as well as contributing to the structure of hair and nails. It is a fibrous structural protein that provides strength and resilience, making it essential for the integrity and durability of these tissues.

In the epidermis, keratin is produced by keratinocytes, which are specialized skin cells that undergo keratinization as they move towards the surface, leading to the formation of a tough, protective layer. This process also occurs in the hair and nails, where keratin helps to create structures that are resistant to damage and abrasion.

Understanding keratin's role is crucial for professionals in fields related to skin and hair treatments, as it influences the health and appearance of these areas. The significance of keratin in the body demonstrates not just its protective properties, but also its importance in various cosmetic and therapeutic applications, which is highly relevant for the practice of laser technicians.
