retinoid positive

Morphology

retinoid = retinol (semi-transparent) = retin + oid

Formation is regular in scientific vocabulary ('retin-' + '-oid' = relating to or derived from vitamin A), but the combining form 'retin-' (and 'retinol') is technical and not familiar to average learners.

Etymology

Retinoid comes from retinol (a form of vitamin A) plus the ending -oid meaning 'like', and retinol was named after the retina (part of the eye). So, as an adjective retinoid means 'related to' or 'made from' vitamin A, which is why we use retinoid products for skin care.
