I had at least five treatments (multiple lasers each), spaced one month apart, and of all of them, I was happiest with picosure. But I had really extensive damage — my skin is much worse than my moms skin, and she sunbathed for many years (the damage is bc of my own idiotic experiementing with essential oils). They totaled it up for me and I don’t recall the breakdown, but 600 usd sounds about right if I broke it down. . . Am going to see the dr this week for some other things; will inquire and if that price is totally off, I will let you know! (The Only reason why I stopped was bc they didnt recommend laser work in the summer due to sun exposure, but i will probably resume in fall). I also have a really low pain tolerance, and multiple laser treatments at once is a lot
note: my dr. was adamant that if you do any of this laser work, you must wear sunscreen. Regular sunscreen gives me milia so I bought a powdered sunscreen (hugely expensive — I think it was 130 usd for a small container — andwho knew there was such a thing) and the damn built in brush doesn’t work. I think Sephora has a less expensive version, if you go that route, but honestly I ended up just using a Helen kaminski visor hat and mask. (But basically, I’m almost never in the sun as DH and I are couch potatoes who are outside for exercise only in the early morning).
by the way, re anti-aging regimens, as per OP, i space (Botox and filler) more than 3 months apart. Doesn’t look shiny, weird or artificial. The difference is subtle but IMO makes me feel a lot better.
