Purified botulinum toxin is used to soften facial lines and wrinkles.
Botulinum toxin works well for forehead lines, crow's feet, and frown lines.
Purified botulinum toxin is injected into the muscle in these areas and works by weakening the muscle, which in turn lessens the lines of facial expression. The results last 4-6 months. By combining botulinum toxin with peels, daily alpha hydroxyacid , and tretinoin cream , a patient can look years younger without surgery. One in ten patients will develop a small bruise or hematoma, which will take several weeks to resolve. Extremely rare double vision has been reported, this can last 3-6 months but is always reversible.
