But let's put it this way, my lips were so thin (hubby's too) my sister asked me more than once, "How in the world do you two KISS each other? I mean, my gosh, NEITHER of you have any lips!"
It was a running joke to which we'd always answer, "our lips are on the 'inside'."
They simply puffed out a bit. I felt the twitching that first full year of supplementation...
Lips are MUCH softer now, too - notably so (to myself).
Sometimes I just want to kiss myself - and that came in handy - especially in the days of my bromide detox!
