How can I repair extremely fragile skin not brought about by meds or age?

Genetic Skin Problem. People who have very fragile skin that bruises easily without being on blood thinners or age-related may have one of several genetic conditions that cause skin fragility. The most common cause like this is ehlers danlos syndrome. This is caused by a defect in the production of collagen in the skin and possibly other parts of the body (like blood vessels or joints) see your doctor.
