If I press my lips together, I can feel the
fluid. Even though the
border of the lip
is visible, there is a band of darker pink/red on the outside of the border.
At first, I thought it may be photo-contact dermatitis because I just started using a new sun
screen yesterday and I did stay out in the sun
for a while. However, I used the sun
screen all over my face and chest with no problem, whereas what I'm describing is limited to my upper lip.
