'non-keratotic' originates from the prefix 'non-' meaning 'not' and 'keratotic' from 'keratosis', which refers to a condition of the skin characterized by an overgrowth of keratin.

'keratosis' transformed from the Greek word 'keratos', meaning 'horn', and eventually became the modern English term 'keratotic'.

Initially, 'keratosis' referred to a 'horn-like' condition, but over time, 'non-keratotic' evolved to describe conditions lacking this characteristic.
