How Botox Works
Botox is a treatment based on sound medical science, notwithstanding its image as a wonder treatment. It's a non-invasive, FDA-approved cosmetic treatment for wrinkles in the upper face.
It isn't a type of dermal filler. It helps to relax the facial muscles that cause lines and wrinkles in certain parts of the face. Botox is a neurotoxin that is injected into the muscles of the face to stop nerve signals and relax them. Lines become less visible and therefore do not worsen when facial muscles are not strained.
You are not alone if you are troubled by forehead creases, brow wrinkles (11 lines), or crow's feet. These are among the earliest wrinkles to show on the top face.
