Massaging which nerve affects the skin of the lower eyelid and upper lip?

The correct answer is the infraorbital nerve. This nerve is a branch of the maxillary nerve and is responsible for providing sensation to the skin of the lower eyelid, upper lip, and part of the face. When massaging this area, stimulating the infraorbital nerve can enhance skin tone and relieve tension, particularly in the regions supplied by this nerve.

Understanding the anatomical relationship of the infraorbital nerve is crucial for estheticians, as it allows for effective treatment protocols targeting specific facial regions. The other nerves listed, while also significant in facial sensation and movement, do not have the same direct influence on the lower eyelid and upper lip as the infraorbital nerve does.
