Imagine your doctor needs to remove a small lump from your arm. Instead of putting your whole body to sleep, the doctor can apply this cream right on that spot.
Your skin goes completely numb in that area. You will feel comfortable while the doctor performs the procedure. This is the main use for this cream.
Doctors usually apply it to prepare your skin right before a minor medical procedure. It makes things much easier and pain-free for you.
