OK I’m finally sitting down at the laptop and looking through my order history. Something about AliExpress that seems quite messed up to me is that contrary to Amazon, where vendors optimize ONE page for hopefully the highest conversions and then would never want to lose the link as it gains SEO momentum, on Ali product links expire all the time while the same product can pop in from the same or different vendors under the same or different price but CERTAINLY different link and SKU. So some of the products I bought have “expired” and I had to hunt them down again at the best prices I could find:

That’s the RF microneeding device. It comes with a handful of disposable heads but they run at around $5 beyond that. Used every 4 weeks you see the marginal cost of consumables is almost nothing. There are more heavy duty, professional devices out there, for example google “Morpheus 8” treatment and you’ll see. That device costs more and it’s more powerful but also easier to get injured by. Someone dishing out hundreds of dollars per treatment at a med spa or the like would probably wan to get more bang for their buck but I am of the opinion that it’s better to do the gentler treatment every 4 weeks for a year straight and beyond, then do a handful of Morpheus 8 treatments and run out of $$ runway. Longer down time too. But still, the super powerful device only costs near $1700, and not $35,000!

I’d order the above if I wanted the best of the best but I am satisfied with my simpler device.
As to my Q Switched ND Yag laser, the model I have is now outdated, so I can only find the latest version. Here you go:

It’s gentle and non ablative, with different heads for 1064nm, 537 nm and another one too. I don’t know if this is what Bryan Johnson is getting for his weekly laser sessions but if his skin team is smart, it should be. My only problem has been sticking to the weekly schedule. I find excuses to not do it as often but the results on my lips are encouraging so lately I’ve been more diligent (You can’t or rather shouldn’t micro needle lips).
I own and really like this device but I found a time limited special and paid less. This is the price now and 90% of the time:

I use it on non-fibroblast mode because I have kids to pick up from school and can’t handle looking like I got eccentric tattoos on my face even for a few days. If downtime weren’t a factor I’d totally use the fibroblast mode. I use the tightening tip and the permeability enhancer heads currently and they absolutely work. I’m getting even more improvement around my eyelids. But it’s slower going, can be used every 72 hours. If money was no object, or less of an object, I would buy this device as it’s the cream of the crop and even uses genuine cold plasma with no thermal effects:

I’ve used simple RF devices in the past with good results but mostly on the body. I also had some modest improvement on the face but to be frank I just couldn’t stick with the regular weekly use I was supposed to invest in it. None of this stuff works on you by collecting dust on the counter. Around Xmas I have my eye on this device:

Look up TECAR / Indiba on google scholar and you’ll see why I’m interested.
Well I’m actually torn between the above and this – it’s the best high intensity focused ultrasound machine I’ve seen in the market so far:

Got a lot more devices but these are the heavy hitters for skin that I use regularly or swear I would if I owned them 
I also have a red + infrared light panel that my husband might love even more than I do – gets used daily.
