Treatment of PIH after fractional CO2 laser peel. I am Chinese and have done fractional CO2 laser for three times. Some improvements on my acne scar in the first two times with about 1 weeks downtime after treatment. However, I have serious hyperpigmnetation after the third CO2 laser peel. The laser in the third treatment is stronger.
It has been four weeks over with application of Hydroquinone in the last week, but the pigment in my skin is still about the same. One doctor suggests me to do TCA chemcial peel and the other suggests me to do Intense Pulsed Light in few weeks.
What should I do or do you have other suggestion which is safer and faster??? TCA, IPL or other treatments for serious PIH after fractional CO2 laster???
