I've just read about krokodil and saw some quite hideous pictures about what it does to the human body. I guess just desomorphine alone wouldn't have this effect.
Which ingredient(s) causes the damage to the tissue?

From what I've read, it's not necessarily 100% known, most likely because it's not easy to study (small, reclusive users who die quickly of a complex concoction) but the line everyone has quoted is:
That's from Dr. Frank LoVecchio in Phoenix, Arizona, who saw two cases within a week. It's not hugely scientific, but it's not wrong. Krokodil is never pure and highly toxic chemicals are thus injected into the veins. If you want specifics, then gasoline, hydrochloric acid, phosphorous scraped off matchboxes, paint thinner, iodine, and cleaning oils. Injecting any one of those should be enough to kill a repeated user. Those substances rupture blood vessels, and the subsequent leakage creates gangrenous wounds like you see in the pictures.
