I think slightly but as to whether it is lips or general face changes I can't tell. I just got out of the shower after washing my hair and had it tied up in a turban towel. Looking at my face carefully it has changed a lot and it isn't just due to being hairless.
Of course it is always subjective.
One thing though, I really like kissing, he was never a kisser. And no explanation for that either! But I will take it as yet another bonus!!
