First off - I'm not paid to write this and I bought this with my own money. I'm 40 years old and I am a huge DIY'er for at-home anti-aging devices and products. I have used a ton of different devices and this is the strongest RF I have ever used. I could literally feel my skin almost changing immediately and hours later. It was a very unusual feeling, very subtle, but I could tell this was WAY stronger than my other device that was 3 times the cost of this one. Plus, I really like the larger area it covers with the body attachment (I used it on my face). I can do a treatment in half the time because of this as well. Overall, I have used this once and I literally said, "WOW, that was a game changer!" Very strong, heats up really quick and I could feel it working - I know that's weird to say but it's the truth. Another thing to note, the next day my skin was amazing on many levels. It's hard to put into words but I examine my skin daily and keep a skin diary that keeps track of my procedures, the outcomes, the way I felt afterward, how my skin looked/reacted, etc. After using my other RF device, my skin would just be warm and pink. I never noticed any changes immediately or the next day. But after the MLAY, my skin feels tight and toned, my pores look smaller, I have a glow and I am hooked!!! I'm already looking forward to my next treatment.
