In San Francisco Bay Area, laser resurfacing for face performed by a board-certified dermatologist may vary from $2500 to $3500. In our clinic, we provide discount for additional anatomic locations such as neck or chest if performed on the same day as the face treatment. I am sure you can find much cheaper price if procedure is done by a physician assistant or a non-core aesthetic provider. Always ask point blank, how many laser resurfacing cases of your specific skin type and priorities (e.g. acne scarring) that your aesthetic physician has performed and if there is no mention during initial consultation of possible complication or steps to minimize complications, you should run away.
