And this is the primary reason that creams containing epinephrine are generally hated by tattoo artists. And this can lead to lopsided or otherwise distorted tattoos when the effects of the cream wear off. And numbing creams with epinephrine will often cause clients to ‘ rash out‘.Īs a powerful vasoconstrictor, epinephrine artificially tightens the skin to which it’s applied. Now, while epinephrine does increase how long the numbing agents in a cream will last after each application, it more often causes clients to experience adverse effects. They open blood vessels and increase blood flow, which then carries them away from the site of application.Įpinephrine is a powerful vasoconstrictor that decreases swelling and is thought to increase the effectiveness of numbing creams. It prevents the active numbing agents from being carried away by the blood vessels. Both lidocaine and prilocaine (active numbing agents) are vasodilators. Yet, the stronger creams will also incorporate prilocaine and epinephrine alongside lidocaine to boost their overall effectiveness. It blocks pain signals at the nerve endings in the skin, making it a safe and effective choice for pain management during tattooing. The active ingredient in most tattoo numbing creams is lidocaine, a local anesthetic commonly used in minor medical procedures. This makes the tattooing process more comfortable, particularly if the tattoo is being placed in a sensitive area. Tattoo numbing creams and sprays contain topical anesthetics that work to block pain signals from reaching the brain.
