The effects of ageing, (I’m 73), and Pred mean that I have to be very careful not to scrape the skin - but that doesn’t always work. So I am a mini expert on what to do when the inevitable brush against a hard surface results in the skin folding back like tissue paper. If it’s very deep go to A&E. They have a fabulous dressing you don’t get in your GP practice unless lucky. It reduces scarring and keeps the wound clear of infection. So, the info.
Don’t disinfect the wound if possible. The nurse told me the body produces its own protection. If you do disinfect use a very mild lotion.
Try to ease the folded back skin over the wound as far as you can, tweezers can help. Cover with a hydrocolloid (wet) dressing and leave for five days or so. You can see through the dressing and the yellow is the gel not pus. When you change the dressing sluice the wound with saline water and leave to dry. If it’s a bit bloody still I use an antiseptic wipe to clear it. I also use tape to secure the dressing when I shower. Transpore 3M is the one that removes easily without more scratches and pain! If your dressing does get wet change it at once. It can take three weeks to heal depending on the kind of tear so you have to be patient. The result is worth it however. No antibiotics for an infected wound and a pretty good pale pink patch. I view mine as a timeline 😂 I do hope this helps. The pic shows the products I’ve found to be most successful. Obviously this is what works for me and you will have your own methods and discoveries but I thought it worth sharing and perhaps opening the discussion 😀
