I Had a Facelift and my Smile Seems Asymmetrical; is This Temporary or a Mistake?

Your facelift was only one month ago so your tissues are still recovering.  Depending on what type of facelift you had there are several reasons for the asymmetry, from swelling, sutures and scarring.  The vast majority of these problems are temporary and the next few months should see your smile return to normal.  Be sure to follow up closely with your plastic surgeron so this can be followed.

The asymmetry was likely present preop, and will be obvious on your before photos; pts tend to scrutinize their faces after surgery and 'find' differences post op. that being said , you are only a month so you still have swelling and healing that is occurring, by 2-3 months everything will settle down better and any obvious asymmetry that was not present preop should resolve.
