Photorejuvenation is a specific form of skin rejuvenation that involves skin treatment using lasers, intense pulsed light (IPL), or photodynamic therapy to reduce the signs of wrinkles, fine lines, age spots, freckles, scars, acne marks, and many other imperfections. Each of these methods of photorejuvenation create microscopic wounds in the skin in order to encourage the growth of new skin cells. These new skin cells then give the skin a more youthful appearance and eliminate the targeted imperfection.

Laser resurfacing is a form of photorejuvenation that uses a laser device to create small wounds in the skin to ensure results. There are two different kinds of lasers, ablative and nonablative.

Ablative laser resurfacing is considered an invasive procedure that likely has to be done by a surgeon under anesthesia. The concept is the same as using nonablative lasers since they both create wounds on the skin in order to promote healing and the growth of new skin cells. Ablative lasers, however, create a significant number of wounds that will require several days or weeks of downtime. It is a single treatment, unlike nonablative laser resurfacing, which can require several treatments depending on the desired results. Many prefer nonablative lasers though, as they provide great results and require little or no downtime after each treatment.
