When injected into a given area Neurotoxin, which is the trade name of Botulinum toxin type A, reversibly blocks the impulses from the nerves to the tiny facial muscles that are related to expression lines. By doing this, the muscles cannot contract or move well enough and therefore tend to relax. When muscles relax, the overlying skin remains smooth and unwrinkled while the untreated facial muscles continue to contract in a normal fashion, allowing normal facial expression to be unaffected.

There are several different types of Botulinum toxins (A, B, C, E, F).The Botulinum Toxin used for cosmetic purposes is the Type A Botulinum or BTX-A. Botulinum Toxin of type A is marketed under the names of Neurotoxin, Neurotoxin-Cosmetic (USA) and Vistabel (Europe) by Allergan Laboratories and under the name of Dysport by the Ipsen-Biotech Laboratory. Neurotoxin and Dysport are the specialities used in medical indications (ophthalmology, neurology, and otorhinolaryngology). Vistabel and Neurotoxin-Cosmetic are the specialties of the Allergan laboratory which obtained the marketing authorization (A.M.M and FDA approvals) for wrinkle correction but their action is exactly identical to that of Neurotoxin.

Depending on how deep the line is, Neurotoxin will undoubtedly help and most times smooth it away. However if the line is very deep, sometimes further treatment with an injectable skin filler is required in order to get the smoothing of the skin.
It is important to understand that whilst Neurotoxin is well tolerated by most people, patients who are pregnant or have neurologic or muscle disease should not be treated.
