I have one along my jawline from an old Fraxel Re:store burn. I've had injection after injection. It's flattened some and DEFINITELY not as hypersensitive as it was. It used to hurt when water would touch it in the shower. The best result I've had was from three light Fraxel Re:store sessions, PDTs, and short IPL treatments. I went to a plastic surgeon to see about cutting it out and stitching it back up, but the price he wanted discouraged me.
What are PDT's?
Also am I understanding you correctly about this scar...........if it was a burn mark that was raised was it like a hypertrophic scar? Because you said it 'flattened"
PDT = Photodynamic therapy. A photosynthesizing agent -- ALA (aminolevulinic acid) was used on me -- is applied to the face, allowed to "marinate," then the solution is activated with light. I can't remember for sure, but I believe I "marinated" (for lack of a better word, but it's how I think of it, LOL) for about an hour before I laid down in a comfy doctor's chair under a blue light. The second and third visit involved a red light and a blue light, from what I remember. You have to be very careful about sun exposure afterward, and the skin will slough off on its own as it heals. This treatment is used against skin cancer/abnormal skin cells and for treatment of acne...killing the bacteria and helping to slow the overproduction of oil. I have also read it can be used for psoriasis, viruses, and microbes. There are several photosynthesizers out there...I believe the one I had was Levulan. I've read that PDTs have worked wonders and then again haven't done much. I'm one of those that it didn't help very much. However, I will say that I was told my acne would be cured after one PDT. Well, it wasn't cured after the first visit ("You might need one to two more"), it wasn't cured after the second visit, and it wasn't cured after the third visit ("You might be one of the ones who have to have maintenance done").
Sooo I now feel very misled by the doctor. Much later, after all this time, energy, and money, I found an excellent dermatologist who informed me that when he does PDTs he recommends between six to 12. Ugh!
Anyway, if I ever choose to have any PDTs done again, I'll use my derm. It did temporarily help me with oiliness and pore size, and some fine lines around my eyes were reduced. Even those I am griping about my experience, if you're interested in getting a series of PDTs, read up on all the info you can and find a really good doctor. You may have excellent results where I didn't.
And yeah, the burn I received from the Fraxel Re:Store turned into a hypertrophic scar. I didn't realize the burn was as bad as it was, so I unknowingly didn't address it and treat it properly. Hence the scar. I've never had a hypertrophic scar before. Many of the various treatments I've had to help with the depressed acne scars have helped flatten this hypertrophic scar, but over time it has gradually raised back up. I've found a plastic surgeon I trust, and when I have the funds I plan to get it cut out, stitched up, and treated properly.
