Type A Versus Type B

Rancho Mirage, Calif. -- A recent study rating the effects of botulinum toxin B in the treatment of hyperkinetic facial wrinkles showed that Myobloc is an effective treatment for interglabellar wrinkles. And while Myobloc showed some advantages over the more commonly used Botox (botulinum toxin A), the longevity of the treatment is about one or two weeks less, even at higher dosages.
