I am applying the X39 at the base of my neck. I bend my head forward and place it where the bend ends. I use one patch and wear it 12 hours.
I use the Aeon patch at night. I place it 2 inches below my navel.
I started these patches on April 17. I noticed the crepiness in my arms disappeared after about 8 weeks (which blows me away because I was so self-conscious about my arms).

My husband had debilitating lower back pain. It's hard to watch someone in so much pain. We went to a spine surgeon who did an MRI and said his lower back was trashed and recommended him for steroid injections. He has Parkinson's so isn't a candidate for surgery. We had trouble with insurance so the shots were delayed. I decided to try these patches. I place the Aeon patch at the base of his lower spine. Within a few weeks, his back pain disappeared. We never did the injections.

Look, I realize it's an MLM and I'm not selling it. But there is something legitimate here. My husband showed me he can touch his toes when before he could hardly move.

I think you have to commit to use them consistently for a period of time and see what happens. I'm 62 so I'm going to stick with it for 6 months. They say one month for each decade. Hope this helps.
