BACKGROUND AND

OBJECTIVE

Laser induced post inflammatory hyperpigmentation PIH, is a complication seen mostly in dark skinned patients, it is not known whether giving the laser treatment at specific menstrual period days, may predispose to PIH.

METHODS

Seven volunteers underwent fixed fractionated CO2 laser treatments at four predetermined days spanning the menstrual cycle.

RESULTS

Two volunteers developed hypopigmentation while the rest had hyperpigmentation. In those who developed PIH, the pigmentation was most severe when done just before or after menstruation.

CONCLUSIONS

Laser induced PIH risk may be influenced by the menstrual cycle.
