Keratin is a tough, fibrous protein that is naturally produced by your body. It's the key building block of your hair, skin, and nails. The production of keratin is a complex process involving your genes and the environment. Your body may produce extra keratin due to several factors, including:
- Inflammation: When your body is fighting off an infection or dealing with irritation, it may produce more keratin as part of its natural defense mechanism.
- Pressure: As a protective response, your body can generate extra keratin in areas that are exposed to repeated pressure or friction, like the soles of your feet or your hands.
- Genetic conditions: Certain genetic conditions can lead to an overproduction of keratin, resulting in conditions like hyperkeratosis or keratosis pilaris.
- Other factors: While not fully understood, some scientists believe that factors like eczema or atopic dermatitis may contribute to increased keratin production.
While keratin production is often a normal process, excessive production can lead to various skin conditions. These conditions often involve the formation of thick, rough patches of skin, blocked pores, or bumps.
