I believe it was in the 90s, but there was a CM for Coppertone expanding sun tan lotion. There was a scene were an middle aged woman's lip expanded during it.
It's a longshot but does anyone remember this?

Old Coppertone Commercial
found it
its a commercial for coppertone wacky foam from the 2000s, not the 90s
it has female lip inflation at around the 5 second mark like you said
