BTA is a medication which relaxes facial muscles. It can improve wrinkles that are caused by muscles that move. This is most effective in the forehead, around the eyes, and in the area between your brows.
Fillers represent a wide spectrum of products that are used to enhance facial volume. These products can last from months to years, and some even beyond. Fillers actually fill in the deeper wrinkles like those between your nose and mouth, and can plump your lips!
