Botox® Cosmetic and Dysport® are both medicines that reduce unwanted lines and wrinkles in specific areas of the face by quieting the underlying muscle activity. In areas such as the forehead, glabella (area between the eyebrows), crows feet ( the area around the outer corner of the eye) and areas around the mouth, the skin and underlying muscle connect so that when the muscle tightens, the skin overlying that specific muscle folds. As skin loses elasticity, frequent folding of the skin will eventually leave a crease in the skin even when the muscle is at rest. To improve the lines in the above-mentioned areas, it is critical that the muscle activity be controlled. Botox® Cosmetic and Dysport® are chemically identical neuromodulator proteins that are manufactured to block the nerve endings release of the neurotransmitter acetylcholine so that the muscle can not contract . The beneficial effects of these medicines first appear about 2-3 days after injection, reach their maximum benefit by about day 10 and last on average between 3 and 5 months. To maintain the relaxation of the facial muscles that have been treated, retreatment is required. If the effects of the medication are allowed to go away completely, the muscles will simply return to their normal activity level unless the muscle has been kept asleep continuously for about 2 years or more. In that circumstance, the muscle may have atrophied to the point that some residual weakness may persist even if these medications are not continued. However, muscle atrophy cannot be reliably predicted.
Additional aesthetic uses for Botox® Cosmetic and Dysport® include balancing facial muscle activity in patients with facial paralysis, lifting of the eyebrows and corners of the mouth, opening the eyes in patients whose eyes become excessively squinted with smiling, controlling bunny lines on the nose, reducing the lateral fullness of a face by treating the masseter (chewing) muscles, reducing chin dimpling and dropping the upper lip to reduce excess maxillary (upper jaw) gum show.
Lastly, some of the most exciting news in neuromodulators is the growing body of research showing that Botox® Cosmetic and Dysport® not only relax muscle, they rejuvenate aging skin. A link has been established with Botox® Cosmetic and Dysport® injections and the prevention of free radical release by cells – essentially an antioxidant effect. These medications have been shown to also alter collagen and elastin in the skin, which not only makes the skin look less wrinkled but actually makes it appear younger at the same time.
