I had never heard of these before I got a sample in my box....
I put it on before bed (easy to apply) and by morning the lines between my eyebrows were so diminished. It works!!
I couldn't frown for a couple hours so it does have lasting power.
Who would have thought?
For a special occasion or before a photo these will be my splurge. I'm 41 and not excited about injecting foreign chemical into my skin.
Give them a try. Now, if they could make a full face version:-)
