Botox is able to do this by directly blocking the facial nerves that tell your muscles to contract.

Not all wrinkles are treated equally.

While Botox cannot erase these deep creases, it may help to soften them.

Botox isn’t reversible once it has been injected, but it does wear off.

Its effects typically begin within 48 hours of injection and become noticeable within five to 10 days.

In the end, it is always important to be realistic aboutwhat Botox can and cannot do.
