Wrinkles and Frown Lines
Years of Squinting and frowning can leave deep wrinkles that form between the eyebrows and may extend to the bridge of the nose. Wrinkles andFrown lines also may appear across the forehead and at the corners of the eyes (crow’s “feet”). Dermatologist can quickly and safely injectBotolinum Toxin during an office visit to diminish these wrinkles and lines that create and angry or sad look and detract from a pleasant facial appearance.
What is Botolinum Toxin?
Botolinum Toxin type A and Botolinum Toxin type B are purified substances, derived from a bacteria, that block muscular nerve signals. Injecting very small amounts into specific facial muscles blocks the muscle’s impulse. This temporarily weakens the muscle and diminishes the unwanted lines.
Botolinum Toxin has been used since 1980 to treat many muscle disorders such as lazy eye and uncontrolled blinking. It was pioneered by dermatologic surgeons for cosmetic use in 1987.
Botolinum Toxin type A is specifically indicated for the lines between the eyebrows , and it also can effectively used for “off-label” indications of other facial areas.
Once the muscle is weakened and relaxed, it cannot contract. Since there is no way to make the undesirablefacial expression, the lines gradually smooth out from disuse, and new creases are prevented from forming. Other muscles such as those needed to raise the eyebrows are not affected, so a natural expression is maintained. For optimal results, Botolinum Toxin therapy may be used in combination with other cosmetic skin procedures such as chemical peels, laser resurfing, and dermal fillers. Combination therapy also can help prevent the formation of new lines and wrinkles. Botolinum Toxin is less useful for the smile lines around the mouth because action is this area is needed for important functions such as eating and talking.
Botolinum Toxin Therapy
Before treatment, the dermatologist obtains the patient’s medical history, including any medications taken. Treatment involves injecting very small amount of Botolinum Toxin directly into the underlying facial muscles to relax them. A tiny needle is used; the procedure is well tolerated and takes just a few minutes with no “down time” or prolonged recovery period.
Botolinum Toxin takes effects about 3 to 7 days after treatment. The improvement generally lasts about 3 to 4 months; the effect gradually fades as muscle action returns. Patients require re-injection at various intervals. With repeated treatment, atrophy (thinning) of the muscle may occur. This usually produces longer-lasting results.
- Vertical lines between the eyebrows and on the bridge of the nose.
- Squint line (crow’s feet) at the corners of the eyes.
- Horizontal lines on the forehead.
- Muscle bands visible on the neck, commonly known as “turkey neck”.
Are There any Side Effects?
Side effects are generally minimal, temporary, and typically relate to the local injection. Soreness or mild bruising, while uncommon, may occur around the injection site. Makeup may be applied after the treatment, but care should be taken to avoid pressing the injected area for several hours. A temporary headache is not uncommon after injection in the forehead area, especially after the first treatment. In rare instances, patients may develop weakness of the neighbouring muscles leading to a temporary droopy brow or eyelid. All of these possible effects are mild, reverible, and self-limiting.
Hyperhidrosis (excessive sweating) can be treated with injections of a highly diluted form of Botolinum Toxin which is superficial injected directly into the underarm skin, skin on the palms of the hands, or on the soles of the feet. This weakens the action of the skin’s sweat glands which are responsible for excessive perspiration. A single treatment session can provide months of relief, and injections can be repeated when the excessive perspiration returns. Twitching muscles can also be treated by injecting Botolinum Toxin into the appropriate muscle.
