Those lines that form between the eyebrows are a result of powerful muscle contractions caused from concentration or frowning. After time, the skin in the area creates a crease or fold. This crease can remain even after the muscle is relaxed. Because Botox works to block the chemical that causes the muscles to move or contract, the "ideal" time to get Botox is before the crease becomes noticeable at rest.
Most Botox treatments take as little as 10 minutes and require no anesthesia or recovery. One of the best things is you won't even look like you had work done. Within a couple of days after the treatment, there is a softening in the appearance of the frown line and noticeable results may continue to improve for about two weeks. Of course, everyone's results vary but in most cases one can expect visible results for about three to four months. Botox works on all skin colors and textures, and both men and women of varying ethnic backgrounds and skin types are treated.
