Darker laugh lines (Photo)
Doctor Answers 1
Inflammatory Hyperpigmentation is darkening of the skin in response to an injury. Injury could be from trauma, or even treatments to the area such as laser treatments. In the case of your laugh lines being darker, it could be due to biting the inside of the mouth. Here are my suggestions:
1. Stop this habit before it progresses to more deformities.
2. Consult a physician familiar with skin of color, to prescribe brightening topicals.
Progress and improvement will be slow in the order of 2-6 months. The sooner you start the earlier you will see resolution of your condition
