What is the name of the area of skin between the nose and the upper lip / mouth?

What is the name of the area that is between the nose and the upper lip, circled in figure 1 below?

I have found that the area circled in figure 2, the small indentation under the nose, is called the "philtrum," which is what the many searches I have tried have yielded, but I cannot figure out what the entire area is called.

The upper lip, the image below is from the wiki entry on philtrum.

This is an interesting question because there is no simple answer. One of the challenges in answering it is that 'lips' and 'lower/upper lip' refer to different things.

Lips

There seems to be broad agreement on what 'lips' (plural) means. They refer to the pink part, which you'd apply lip balsem or lipstick to.

Upper lip, lower lip

There is less agreement about 'lower/upper lip'. The accepted definition is that these words refer to both the pink and the skin-colored part. But this is a larger area than what 'lips' means, so that obviously leads to confusion, because a lot of people use 'upper/lower lip' to refer to only the pink part.

Cutaneous lip

So, we've been talking about 'just the pink part' and 'both the pink part and the skin-colored part'. What about 'just the skin-colored part'? In colloquial English, there is no dedicated word for that. So let's settle for a scientific or medical term. "The skin-colored part of the lip" is called the cutaneous lip.

So the best answer to the original question would be cutaneous upper lip.

Summary

• Lips usually refer to just the 'pink' parts.
• Lip usually refers to a larger area:
• Upper lip is everything between the mouth opening and the base of the nose.
• Lower lip is everything between the mouth opening and the chin.
• Vermilion zone is the pink, non-wet part of the lips.
• Cutaneous lip is the skin-colored part of the lips.
• Philtrum is a vertical subsection of the cutaneous upper lip, between the ridges under the nose.
