Which area of skin is NOT affected by the supraorbital nerve?

1. Forehead

2. Lower eyelid

3. Nose

4. Scalp

The correct answer is: Lower eyelid

The correct choice, which identifies the area of skin not affected by the supraorbital nerve, is the lower eyelid. The supraorbital nerve primarily innervates the forehead, parts of the scalp, and the bridge of the nose. Its main role is to provide sensory innervation to the upper region of the face. The lower eyelid, however, is primarily supplied by branches of the maxillary nerve, specifically the infraorbital nerve, which provides sensory function to that area. Thus, since the supraorbital nerve does not extend its reach to the lower eyelid, it is not innervated by this particular nerve, making it the correct answer in this context. Understanding the specific pathways of cranial nerves and their associated skin regions is crucial for estheticians, as it impacts both treatment techniques and the management of skin conditions within the areas they serve.
