Red acne scars (PIE) removal? (Photo)

This is quite a common problem following the clearing of active acne lesions. It is called PIE or post-inflammatory erythema (redness). Unfortunately, there's way too much marketing and social hype (and, unfortunately, precious little hard science) pushing the use of the expensive bells and whistles energy-based devices, which so often result in big expenditures and little to no benefit, as in this case. I have personally had success dealing with this issue manually performing medical microneedling accompanied by the application of vasoactive and vasoconstrictive medications. You would wise to consult a board certified cosmetic dermatologist and best of luck.
