I had Botox for a “lip flip” and now, 1.5 weeks later, the right side of my smile is crooked. What happened? (photos)

I would tend to agree that the Botox Lip Flip is nothing more than a gimmick. Usually the Botox is used in combination with lip fillers and it is the filler that does most of the work in flipping the lip up. Injecting the upper lip with Botox is a very advanced technique and I have seen way too many undesired results from injectors that don't have the experience treating the area. I would not do anything more than just give it time to wear off. Things will go completely back to normal, but it may take 2-3 months to do so. Make sure you are under the care of an experienced physician injector next time. Best wishes.

Botox Botox BotoxThis is not necessarily the answer for everything and can quite  possibly be the cause of results that we consider unfavorable. The neuromodulator botulinum toxin- A  works by blocking the nerve connections to the muscles. This often takes anywhere from several days to upwards to a week for it to take effect. Changing the contour of the lip structurally is what the filler can do. The Botox leads to decreased animation and over time can improve the signs of fine lines and wrinkles. A crooked smile that comes on approximately a week after treatment is more likely a secondary result of neuromodulator that has drifted into an area that was perhaps unintended. Look for an injector who has expertise in facial anatomy specifically a plastic surgeon. Following up with the injector who did treat you is always a good idea for thoroughness of care.

This may be due to placement. Fortunately, Botox results resolve in 3-4 months. I recommend following up with your injector. A well-placed touch-up may give improvement. Hope this helps.
