The effect of menstrual cycle on laser induced hyperpigmentation
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.

Hormonal Regulation of the Menstrual Cycle
At puberty, GnRH begins a pulsatile release pattern, which triggers the anterior pituitary gland to secrete follicle-stimulating hormone (FSH) and luteinizing hormone (LH). The frequency and amplitude of GnRH pulses vary across the menstrual cycle, with faster pulses favoring LH release and slower pulses favoring FSH...

The menstrual phase occurs from days 1 to 5 and involves the shedding of the stratum functionalis, as a...
Proliferative Phase
Notably, the stratum basale, the basal layer of the endometrium, including the basal parts of the uterine glands, remains unaffected by menstruation. Stem cells in this layer undergo mitosis, regenerating the stratum functionalis and thickening the...
Menses Phase
When fertilization does not occur, the corpus luteum deteriorates, causing a significant drop in the levels of estrogen and progesterone in the body. This hormonal decrease triggers the release of prostaglandins, which cause the uterine...
Pigmentation
Melanin occurs in two primary forms: eumelanin that provides black and brown pigment and pheomelanin that provides red color. Dark-skinned individuals produce more melanin than those with pale...
