Spells would not be the particular approach to your solution, however elixirs and herbal solutions or some good ol' scar creme could do the trick. Depending on how deep your cuts are- these below could be useful as holistic remedies. However I would advise buying scar removal creme, as that would probably give you more desired results. Many cremes have enhancing cell turnover (balancing collagen), provide B5 vitamin and usually carry SPF among many other anti-inflammatories which are already found in plant base substance. Although here are some herbal suggestions:
Vitamin E Oil
These can all be applied directly on the affected skin with a cloth or bandage and left on for 30-45 minutes. When done, take the bandage off and rinse your scars with luke warm water and pat dry with a sterile cloth. It might help to use moisturizer afterwards too. Particularly just your average joe shmoe unscented body lotion. None of that bath & body works bs.I hope this helped!
Put your hand on top of your wound/scratch. Close your eyes and imagine roots spreading from your being into the earth. Picture the roots lapping up energy and health. When done, picture a broken heart connecting again, a broken bone healing. Picture anything else that means health for you. Now you're done.
