Botox works by relaxing muscles that cause wrinkles or expression. Like crows feet or frown lines between your brows. It also can be used to soften the shape of your face. For instance it can lift your brows or help correct downturned corners of your mouth. All of these things make you look, and feel younger.
Most people don't realize that Botox also prevents wrinkles from forming. There are two type of wrinkles. Those from expression on others that are there even when your face is totally relaxed. Some of the second type are in the exact place as the muscles of expression. They have formed because the skin has folded and made wrinkles from expression in the same location for years. By treating the expression lines, those permanent wrinkles never form. If you already have the second type of wrinkles, keeping the face relaxed allows your skin to repair itself and the "permanent wrinkles will improve or vanish completely"
Patients tell me every day that Botox makes them feel younger. We all understand that appearance has a big impact on our self esteem and mood.
