Face shrunken 3 months after PRP - will the results ware off?

I've never heard of this type of reaction to PRP before. PRP contains growth factors which stimulate regeneration of tissue in a very natural way, according to your body's direction. The emphasis is on natural tissue regeneration and rejuvenation. The description of drastic tightening suggests that more than PRP was involved, such as filler or the use of an energy device like radiofrequency or ultrasound. More details would be helpful, including platelet dose, injectate volumes, location, depth etc.
