There are factors one should consider regarding laser resurfacing and dark skin tones. This is not to say that laser resurfacing should be immediately ruled out. However, dark skin tones need to be treated slightly differently. With increased melanin, there is the possible risk of complications when laser treatments are done. What happens is that pigment can sometimes absorb laser energy. And, when this happens, there may be postinflammatory hyperpigmentation. So, what is the solution to this potential problem?
Dealing with Dark Skin Tones
The surgeon needs to select the proper parameters when using the laser device. It is essential that adequate cooling is applied during and after the laser procedure. It's also important for the surgeon to not be as aggressive when doing this procedure, especially with higher-risk patients.
Correctly Pulsed Lasers
Rather than using Q-switched lasers, physicians should use long-pulsed lasers instead. This is because Q-switched lasers induce a photothermal effect. They also cause a quick change in the thermal gradient, which oftentimes leads to photomechanical damage. To put it in layman's terms, when energy is delivered so quickly, it makes cells rupture.
Those with dark skin tones should take all of the above information into serious consideration.
