I just had my first session done yesterday, so I can’t speak for long-term results. But I chose it vs chemical peel or laser due to lower price, it’s less invasive and less healing time. Unlike others posting here, I’m only planning on doing one treatment, maybe two max, just to see a slight lessening in acne hyperpigmentation and fine lines. I’m not trying to erase imperfections, just turn back the clock a year or two
From my research, it sounds like pockmark acne scars do require several treatments in order to see a difference. Enlarged pores likewise may require more treatments, but I find the large pores on my nose are also helped significantly (though temporarily!) with a good mask or facial.
As for the treatment itself, I didn’t experience any pain, though it did feel like a slight sunburn afterward. She went deep enough that was micro-bleeding. Today it’s tight and pink. I have olive oily skin so I’m likely to tolerate this a lot better than those with dry fair skin. I’ve also recently added a Vitamin C and hyaluronic acid serum to my skincare regime and think that’s going to help too.
I’d recommend you check out facial treatment options on the Real Self forum - there are tons of reviews and pictures there. And links to providers in your area.
