What does the term 'keratosis' refer to?

The term 'keratosis' refers specifically to a buildup of dead skin cells. This condition is characterized by an increase in keratin, which is a protein that forms the outer layer of skin, hair, and nails. When keratin accumulates excessively, it can lead to various types of skin lesions such as actinic keratosis or seborrheic keratosis, which are often observed as rough, scaly patches on the skin surface.

The distinction in this definition is crucial for understanding skin health and conditions. By recognizing that keratosis indicates a buildup rather than an inflammatory or degenerative process, practitioners can better assess and treat related skin issues. The buildup of dead skin cells can lead to other complications if left untreated, such as blockages in pores or changes in skin texture. Understanding keratosis is essential in esthetics for developing appropriate skincare treatments aimed at exfoliation and renewal.
