Hello I wanted to know if the aerolase laser is a worthwhile financial investment for issues such as post surgical scarring redness hyperpigmentation skin texture improving etc. are there any experts out there who use this technology that can attest to its efficacy? I am considering trying it for these issues but I'd like some more information.. I have Fitzpatrick skin type 4 and large pores on my face and my skin is looking dull and I'm curious on its ability to improve new scars also
