Injectable fillers are used to add volume back to the face where volume has decreased, provide support, correct under-eye hollowing, minimize fine lines, or enhance the appearance of the lips, cheeks, chin and jawline. BOTOX Cosmetic, Dysport, and XEOMIN are botulinum toxins that work by relaxing the muscles that contribute to dynamic wrinkles like frown lines, horizontal lines in the forehead, and crow’s feet. Injectable fillers work to fill in fine lines and wrinkles, as well as areas of the face that have lost volume, lost support, or desire enhancement.
