How to stop a zit from bleeding
Apply hydrogen peroxide and direct pressure to encourage the blood to clot.
Soak a clean tissue or washcloth in hydrogen peroxide, then apply gentle but firm pressure to the bleeding zit. The pressure will encourage the blood to form a clot, while the hydrogen peroxide will kill any bacteria coming out of the zit.

Options are: i. It's important to use at least 80% hydrogen peroxide to avoid sticking to the area. Too much hydrogen peroxide can cause the zit to open up, too much of it can make the zit bleed.. ii. Wipe the area at the injury site with a piece of gauze, a medical blanket, or wax. Stay for 20 to 30 minutes after the zit has hit the wound.. iii. This will prevent your acne outbreak from spreading to the surrounding skin. Note that hydrogen peroxide can dry out your skin, so make sure to moisturize once the bleeding has stopped.. iv. The hydrogen peroxide works very well for stiles and mesothelioma. Hydrogen peroxide will not work on more than one type of zit..
The answer is:
iii.
