What is keratisation?

Answer 1

Keratinization is the biological process by which keratin, a protective protein, is produced and accumulated in the outer layer of the skin, hair, and nails. This process helps to form a barrier that protects underlying tissues from environmental damage, pathogens, and dehydration. In the skin, keratinization results in the formation of the stratum corneum, the outermost layer composed of dead, flattened cells that are rich in keratin. Disorders of keratinization can lead to various skin conditions, such as psoriasis or ichthyosis.
