What can I do about hyperpigmantation/tiena versicolor after laser hair removal on my cheekbones? (Photos)

Hello, I had 2 sessions of cheekbones laser hair removal and the last time I noticed a white patches on my cheeks, and also little brown patches. I'm already see some results from the treatment. I had the white patches before but they definetly not were that noticable. I went to the laser clinic and they told me that they don't think it's from the laser and that it was already there and now I just see it because the hairs not there and that its a tinea versicolor, but I don't if to believe them.
