What Does Botox® do to Rejuvenate the Skin?

Botox® injections rejuvenate the skin helping to eliminate wrinkles, mild creases, and fine lines. The serum used in Botox® injections is made from a neurotoxin, Botulinum Toxin A. The neurotoxin works by paralyzing the muscles of the treatment area, allowing them to relax. The serum also blocks messages along the nerves that go to and from the brain. Botox® injections work at the nerve endings that cause the underlying muscle contraction and block the release of acetylcholine and, as a result, the contraction weakens or stops, creating a relaxation and tightening of the facial skin, which yields an improved cosmetic appearance.As the skin begins to tighten, it becomes firmer and has more tone. This, in turn, smooths out the wrinkles and lines, giving the skin a more youthful and rejuvenated appearance.

How Long Does a Botox® Treatment Last?

Botox® injections normally last for three months. The length of the treatment will depend on several factors. The original tone of the skin prior to the treatment is a huge factor in what type of results the patient receives. Another factor is the length of time between treatments. Scheduling the next Botox® injection prior to the effects of the previous treatment starting to wear off, will ensure the patient maintains the same degree of skin tone between treatment sessions.

Do Botox® Injections Cause Side Effects?

Botox® injections can cause minimal side effects. The most common side effects attributed to Botox® injections include inflammation and bruising in and around the treatment area. The injection sites may feel warm and be tender to the touch for the first few hours. After the initial side effects begin to disappear, tenderness throughout the treatment area may be felt. Any feelings of firmness or rigidity should begin to dissipate after the first few days. The initial inflammation and bruising that occurred immediately after the procedures should only last two or three days.
