A noun in The Etymologies of the 1930s glossed “ruddy (of face)” derived from primitive {ᴹ✶k’randā >>} ᴹ✶k’rannā under the root ᴹ√KARAN “red” (Ety/KARÁN; EtyAC/KARÁN). Tolkien said it could also be used as a noun meaning “face, blush, the cheeks”, much like Old English rudu (Ety/KARÁN). In this document, it was an element in the name N. Cranthir “Ruddy-face”, which in later writings became Caranthir “Red Face” (MR/128; PM/353; VT41/10). However, I think crann remains viable as a Neo-Sindarin adjective and noun; as a noun I’d use it primarily to refer to the cheeks, using thîr for the face as a whole.
