Dr. George J. Hruza: We generate a lot of scars, but we also-- patients get scars from various sources, from acne, very common, or from traumatic, from accidents, injuries. And so we see a lot of patients with scars, and until recently we didn't have great things that we could do for scars. We had some things we could do to improve them, but now we have a lot of options to help the scars, and I think of scars as more of three main types.
There are the thin scars, we call them atrophic scars, depressed scars, and we have hypertrophic, or thick scars, and then keloid, which is these overgrown cauliflower huge scars. And each of those can be treated now and improved with various ways.
So if you have a depressed scar, we have these lasers, fractionated lasers, or what we call fraxels, where the laser puts on thousands of injury spots, and it remodels, reworks the skin, and actually helps create new collagen to recreate the normal, approaches normal skin, so you improve those that way.
If you get a hypertrophic scar, it's a thick scar, you can use another laser to take out redness, called style laser, you can use one of these a fractionated, again, lasers with these injury spots that can remodel the scar and flatten it down and blended in, and you can also make little holes with the lasers, tiny microscopic holes, and then you can put medicine, which can help flatten the scar even further.
So all these things together really can make a big difference in scars.
