Crepey-skin generally indicates that the skin is very thin. A soft HA filler (juvederm ultra or restylane silk) could be injected in a pinpoint, matrix-like fashion to give the skin more substance. However, the effects would not be very long-lasting.You may find the best results with a device that introduces controlled injury to the skin, thereby stimulating collagen production. Depending on your skin type, this device could be a co2 laser (lighter skin types) or a radio frequency device (light- or dark skin-types). A collagen-stimulator, such as sculptra, can also be feathered into the skin to stimulate collagen production. Finally, if you can tolerate a mild retinoid, that will also help to promote collagen in the superficial layers of the skin. Note: retinoids works slowly (over 9-12 months).
