I had a full-face Alexandrite laser treatment done for hair removal (skin type #3). After only 1 treatment I have patches of hyperpigmnetation on my face and neck (lighter on face and darker on meck) which appeared about 5 days after the treatment.
Could you PLEASE let me know if these are permanent or will they fade away with time? I would appreciate if you could also let me know till when do I have to be avoid the sun? Thank you so much!
