Even though Botox cosmetic is one of the most widely used beauty treatments, the uninjected are frequently confused about its purpose. I will attempt to explain how it works and what it is not.
Botox is a neuro-modulator, meaning it reduces signals to a treated area. This causes the muscles to relax and lines to look softer.
The FDA has approved Botox for the forehead, between the eyebrows, and the crows feet area near the eye. It is often used off-label by experienced injectors around the mouth or in the neck as well.
Botox cosmetic was the original neuro-modulator, and there are other, similar products on the market from other manufacturers. Botox is not a filler; it adds no volume to the area it is injected in. It is traditionally sold in units.
A filler is a substance used to plump up an area or to build volume. As we age we lose mass not just in our bones but also in our muscle mass, and this includes the face. So a filler is used to fill that space up again. Juvederm is a filler used in its multiple forms for cheek, lip, and marionette lines, giving a fuller appearance to the face. Most fillers contain Hyaluronic acid, which is a naturally occurring substance in the body. Hyaluronic acid holds moisture which, in turn, adds volume to the face.
There are other fillers on the market as well. Most fillers are sold by syringe.
I hope this was informative!
