The mimic muscles are tightly connected to the facial skin. The contraction of the mimic muscles leads to a visible wrinkle. Repeated contractions of the facial muscles lead over the years to persistent deepening of the facial wrinkles.
Botulinum toxin type A is a substance that impedes heightened activity of the mimic muscles. Frown wrinkles, vertical forehead wrinkles and `crow’s-foot` wrinkles. The injection of botulinum toxin type A also prevents the development of such wrinkles.
Patients look more youthful and relaxed after the treatment. Some facial muscle activity is preserved, so the facial expression stays natural. A rigid look, such as that which sometimes develops after lifting surgery, does not occur. The full effect is usually reached after roughly 14 days and lasts 4 to 5 months on average, or even longer after repeated injections. The use of botulinum toxin type A is regarded as a safe medical-cosmetic treatment method, since the treated area regenerates itself continuously and no long-term changes develop. The injection of botulinum toxin type A can be repeated as many times as desired without problems. It can be easily combined with hyaluronic acid to treat wrinkles.
Several highly effective drops of a highly diluted solution of botulinum toxin type A are injected with hair-thin needles into the muscle to be treated. These needle pricks are barely felt. The initial results are visible after several days. The skin becomes more smooth, lines and wrinkles disappear.
