I'm the person who said I'd use this with my mom. Honestly, I was skeptical—how much better could it really get? I thought I could just go to the clinic instead, but since they offered a refund, I figured I'd try it once just in case. I've been a bit self-conscious about my neck wrinkles, so I've been slathering it on with my mom before bed, and maybe it's because of the botulinum-derived ingredients, but the horizontal neck lines definitely got lighter. So I bought more! Got the 3+1 set lol. I looked into others, but this has the highest concentration and feels light, so I don't think anything beats this.
