Volumizing fillers are routinely used these days by advanced injectors to augment the cheekbones, increase projection, and enhance light reflection. Ordinary Restylane is best reserved for filling simple lines and wrinkles. Voluma XC would be a more appropriate choice and is the product I typically choose in my Upper East Side Manhattan practice. . Another possible product for this purpose is Restylane Lyft. (In my Israel satellite facility, where a far greater number of regulatory agency approved volumizing fillers are available, I typically opt for Stylage XXL and Emervel Volume). All of the above are natura,l hyaluronic acid-based products, and as such are subject to the body's normal, metabolic degradative processes over time. The gradual dissolution and reabsorption of the material does not result in sagging, which is a consequence of the aging process itself and not the fillers and volumizing fillers used to combat it. Botox, like the other commercially available muscle relaxing agents, Dysport and Xeomin, are intended to relax the muscles of facial expression, such as those responsible for the development of crow's feet wrinkles around the eyes, forehead worry lines, and frown lines between the eyebrows. It is not intended to supply volume or projection. You would be well advised to seek consultation by a board certified aesthetic physician with expertise and experience in the advanced uses of fillers for nonsurgical cheek augmentation. Best of luck to you.
