Hi. so a year ago now i had my leg burned by an in trained professional with an IPL laser that left me with hyperpigmentation cubes.. I went to visit a dermatologist and he told me for three months to apply glycolic acid and hydroquinone 4% cream/ i did and 3 months later they patch tested lasered and then proceeded to start treatments in february 2019- so far i've had 2 sessions 8 weeks apart- am wondering if you think it's actually working and how many more will i need for my leg to be normal
