Botox A is a purified protien which has been used for more than a decade in both adults and children to reduce eyelid and facial muscle spasms and to correct double vision due to eye muscle imbalances. Botox A is commonly used for cosmetic effects, such as reducing the appearance of wrinkles. Injections of minute amounts into the muscles of facial expressions calm the muscle and reduce frowning, crows feet, and expression lines. Botox A produces a temporary effect of lessening and smoothing wrinkles which can last 3 to 6 months. $10 a unit
