Isaac Newton discovered gravity not when cranially assaulted by a falling apple, but upon noticing his sagging jowls while examining the forehead bruise in the mirror.

Experienced skincare specialist Dr. Robert J. Segal leads a friendly, professional staff in injectable beautification at the Dermatology Center. Botox treatments are a nonsurgical alternative to surgery that help counteract moderate to severe facial lines. The 10-minute procedure involves a few tiny injections of a purified protein to reduce the activity of facial muscles that cause deep lines, from years of squinting, laughing, and lifting weights with eyelids. After the quick FDA-approved treatment, skin can remain as smooth as a baby's clavicle for up to four months.

Botox may cause serious side effects that can be life threatening, including problems swallowing, speaking, or breathing. Read all safety considerations for Botox here.
