With PRP there may be some immediate results on the forehead, but you can expect to see steady improvements over time which could be 6 months and beyond as your body produces more collagen. The results of PRP will be ongoing. Best results are achieved with 2 or 3 treatments spaced about 2 months apart. Maintenance treatments are recommended every 1 to 2 years for treatments other than acne scars. At Sparclaine MD in Washington we offer Facial PRP treatments for $1250 per treatment. Our procedure is performed by a medical Dr and we use an FDA approved microneedling device and machinery yielding the highest platelet count. Quality and price of PRP treatments vary greatly among practices.
