My skin seems quite thin /fragile, and if I itch my back I'll often cause a scratch. This might be at the location of a small blemish, or nothing at all.
Also, if I scratch a small blemish on my arm or leg, or knock a scab, it'll often bleed quite a lot.
Any thoughts as to what this might be related to? Vitamins? Minerals? EFAs?? My diet is probably pretty lacking in all the nutrients, including proteins.
