Can fillers be used on eleven lines (instead of Botox)?

Great question. The glabellar area or elevens is best prevented by botox. If the wrinkles are static and deep then fillers will help to soften the wrinkles. Now to prevent them from coming back the best option is botox or another muscle relaxant.

Yes, fillers can be used to reduce the resting ‘eleven’ lines that appear between the eyebrows. Fillers work by filling in the creases in the skin by re-supporting the lost tissue both within and below the skin.
Another alternative is to use Botox in combination with fillers. Patients sometimes prefer this because it can allow the fillers to last longer. 
It is important to keep in mind that applying fillers in the eleven-lines area is riskier and more difficult than using fillers in other areas, so it is best to select a physician that is dedicated exclusively to providing cosmetic injectables.
