Hi, my lovely mum is 77, she has very thin skin which bruises and marks very easily. She recently knocked her arm out shopping and through a coat and a jumper took the skin off. The wound has taken ages to heal with regular appointments with the nurse and the GP. She is on some medication which is probably contributing to this but is very mobile and fit. Any advice as to any supplements or creams or anything else which might help? She is going to discuss with her GP too.
