Relating to a condition where the skin becomes thickened due to an excess of keratin.
The doctor diagnosed her with a hyperkeratotic skin condition that required treatment.
Hyperkeratotic → It is formed from "hyper-" (meaning excessive) and "keratotikos" (from Greek "keratos", meaning horn). The term describes a condition characterized by an excessive thickening of the outer layer of the skin, resembling a horn-like appearance.
Think of 'hyper-' meaning excessive and 'keratos' referring to horn-like skin — this helps you remember that hyperkeratotic refers to an excessive thickening of the skin.
