Thanks for writing in.
From your description it appears that you have developed a chemical burn
due to a hyper-osmotic effect of the salt. You description also indicates that it was a 2nd degree burn. Based on this, you should not develop a scar or other permanent damage, unless it gets infected.
It the skin is peeling already - remove the detached skin completely and keep the area clean with a sterile water (over the counter) and keep the area covered with a bandage for 2-3 days with BACITRACIN
ointment. Then, just keep it clean with soap and water. Depending on the area of the body it should heal completely in 1-2 weeks (a pink spot may remain for a few more weeks, but it will dissipate).
Hope this helps
