Frequently asked questions

Is it better than plain petroleum jelly?

For clean minor wounds, plain petroleum jelly often works about as well and avoids the allergy risk. Bacitracin may help in wounds more likely to get infected.

Can I put the skin ointment in my eye?

No. Only products labelled for the eye should be used there.

When should I see a doctor?

If the wound is deep, dirty, from an animal bite, or not healing within a few days, or shows signs of infection.
