How to get rid of mouth wrinkles on adult sims?

I wish I had some tips for you. I'm also very bothered by the fact that my YAs suddenly looked like they were pushing fifty-sixty years old upon aging to adults. We should have an option. Not everyone ages at the same rate. I'm sixty-eight and am just now showing the age-lines (I should say creases) around my mouth. Sheesh. I starred this post, just in case someone out there has an answer.
