I am scheduled for my first microneedling with PRP session next week. I have had my consultation and know what to expect, however I read about individuals who've experienced poor outcomes due to micro tearing of the skin. I'm concerned and would appreciate any feedback from the medical community on which devices to steer clear of and if I should lower my expectations or ask more questions. I am also due for laser for uneven skin tone due to sun exposure and melasma. I'm 50.
