What Happens After Botox Cosmetic Wears Off?

Once Botox has worn off completely, your muscle movement will start to gradually increase and wrinkles will return to their original state prior to treatment. Botox will not cause your wrinkles to worsen.

 

After Botox wears off, the original wrinkles remain in the original depth and size. If the wrinkles do look worse, it is most likely due to sun damage as opposed to the Botox injection. 

Excessive exposure to UV rays will damage the collagen that is responsible for keeping the skin firm and elastic. If the skin has received a substantial amount of UV exposure during the 3-4 month period, then yes, it is likely that the skin will look worse once the Botox has worn off.

Botox will not cause your wrinkles to worsen after injection. If anything, I think your friend's memory may be the culprit. We have had a few patients say to us that they think they are worse off after their Botox wears off until they see their before photo. Once the before photos are evaluated, this is never the case.
Botox may actually have you looking better even after it's worn off because it can cause some muscle shrinkage in the injection areas which in turn can lead to wrinkles that don't look as deep or noticeable.
