I had a full-face laser hair removal treatment done with Alex. laser about 2.5 weeks ago. About 5 days after the treatment I was exposed to the sun for around 10 minutes(without a sunscreen as I am v.sensitive to sunscreens).
The next day I noticed hyperpigmentation on my face and neck. The tech who had done the treatment said they are common and should go away in around 2 weeks- but no improvement yet. Is this permanent and how long should I avoid the sun now, as this was my LAST treatment?
