Botox is most commonly employed to relax some of the facial muscles that cause creases and is most often used in the smile lines (“crows feet”) and the forehead frown lines. Smile lines can give extensive creases to face radiating from the eyes. Frown lines can give a serious and even angry look completely at variance with one’s actual feelings. Both of these can evenually cause permanent creasing of the overlying skin. The muscles that cause both of these problems can be relaxed with Botox without loss of natural expression.

Botox is administered in the office after the application of a topical numbing cream. The effects begin in about 5 days and last generally 4 months or more. It is very safe and has no permanent residual. Botox has been used in thousands of patients, and its safety profile in cosmetic use has been well established.
