Can Fraxel CAUSE melasma to occur?If I didn't have spots on my cheek before Fraxel but now is there a chance it's PIH?(photo)

Active sun lover,do hot yoga, etc. No hx of melasma in family & had non-sensitive skin b4. Had acne scars & a pigment spot (1 round on R cheek)show up after aggressive peel and going to hot yoga too soon. Got Fraxel dual 1 mo later. Hid from light for 3 mos,then outside with 50+zinc & hat most of time after.At 4 mos post, suddenly both cheeks and nose have spots of hyper&hypo pigment. Whats the chance this is PIH from fraxel? Can these tx's CAUSE melasma to come out? Skin is hyper-sensitive now
