excessive keratin production leading to thickened skin patches
Hyperkeratinization is a condition where there is an excessive production of keratin, a protein that helps form the outer layer of the skin, hair, and nails. This overproduction can lead to the thickening of the skin and the formation of rough, scaly patches, and is often associated with conditions like acne, psoriasis, and certain types of alopecia.
