No one. The OTC concentrations have never helped me. I read that the prescription grade is 40%.

Solutions - and a lot more concentrated than 40%?. I mix it with a skin ointment.

I use my bare hand, wash it afterwards, never have a problem. The exposure is perhaps 5 minutes.

That's why it removes callus.

I discovered that there was a point after I removed almost all the callus that urea broke the skin and made me bleed. This took months. Now I apply a 'skin healing cream' (so the label says) and only recently stopped bleeding completely, no longer bandage my bum after every poop and shower.
