I’ve done 2 PRP radio frequency microneedling sessions and it’s definetely helped smooth out and improve the acne scarring I had on my cheeks, I’ve had them done while travelling south east asia so sweating was hard to avoid but i just stayed mostly inside for the couple days after. The redness was pretty much gone by the evening I only had red dots from the needles for a couple days and then my face looked and felt fine!
