Query: Didn't work for me

Didn't experience any difference in lip texture, plumping, moisture, nothing. Tingly? Yes. Anything beyond that? No. Could not use under lipstick in the morning or it would smear off. Applied it, left it on as long as possible but eventually had to remove what was left before applying lipstick. Applied at night before bedtime. No noticeable difference for me. Disappointed.
