What Is Numbing Cream and How Does It Work for PMU & Tattoo Procedures?
Every PMU artist gets asked some version of the same question before a client sits down: "Will this hurt?" The honest answer is that it depends almost entirely on the anesthetic protocol you're running — and that starts with understanding what numbing cream actually is and how it works.

Quick answer: Numbing cream is a topical anesthetic — typically 5% lidocaine — that blocks sodium channels in skin nerve endings, temporarily stopping pain signals from reaching the brain. Per the product's labeled directions, it's applied as a thick layer under occlusive wrap and removed after 20–60 minutes, and should not be used more than once every 24 hours.

How numbing cream actually blocks pain
Numbing cream is a topical anesthetic — most commonly containing lidocaine — that temporarily blocks nerve signals in the skin. It's applied to intact skin before a procedure begins, giving the treatment area time to lose sensation before the first needle pass.
Lidocaine works by blocking voltage-gated sodium channels in nerve cell membranes. Nerves send pain signals to the brain using small electrical impulses, and those impulses depend on sodium ions moving in and out of the cell. When lidocaine binds to the sodium channels in the skin's nerve endings, it stabilizes them in a closed state and prevents that signal from ever firing — so the brain never registers the sensation as pain, even though the needle is still making contact with the skin. This mechanism is well documented in the pharmacology literature; see the NCBI StatPearls entry on lidocaine for the full clinical breakdown.
This is a localized, temporary effect. It does not sedate the client or numb anything beyond the treated area, and it wears off naturally as the lidocaine is metabolized and cleared from the tissue.
What's actually in numbing cream
Elite Numbing Cream is built around lidocaine as the active ingredient, at 5% — the concentration printed on the product's Drug Facts label, which also lists the product's other uses (temporary relief of pain and itching from minor skin irritations, cuts, scrapes, and burns), warnings, and directions.
Some anesthetic products on the market combine lidocaine with other amide or ester anesthetics, or a vasoconstrictor like epinephrine, to change absorption characteristics — but lidocaine alone, used according to its labeled directions, is the standard active ingredient every artist should understand first.
Common topical anesthetic ingredients compared
| Ingredient | Type | Typical concentration range | Notes |
|---|---|---|---|
| Lidocaine | Amide | 4–5% | Industry standard for PMU; well-established safety and efficacy profile at labeled OTC-monograph concentrations |
| Benzocaine | Ester | 5–20% | Higher allergic-reaction rate than amides; less common alone in PMU formulas |
| Tetracaine | Ester | 0.5–2% | Often blended with lidocaine for longer duration; higher toxicity risk at high doses |
| Prilocaine | Amide | 2.5% (often blended, e.g. EMLA-style) | Common in medical anesthetic blends; risk of methemoglobinemia at high doses |
Why the labeled timing matters
Numbing cream needs contact time to work, and the product's Drug Facts label is specific about it: apply a thick layer, cover with occlusive wrap, and remove after 20 to 60 minutes. Do not use more than once every 24 hours. Cutting the contact time short is one of the most common reasons a client reports feeling more than expected on the first pass — and using the product more often than labeled goes beyond its directions for use.
Two variables control how well and how fast it works within that labeled window:
- Skin barrier condition — clean, dry, intact skin absorbs evenly; oil, makeup residue, or broken skin all interfere with predictable absorption.
- Occlusion — covering the area with occlusive wrap, as directed, traps moisture and heat, which measurably speeds and improves lidocaine penetration compared to leaving it uncovered.
Where numbing cream fits vs. numbing gel
Elite Numbing Cream is the primary anesthetic — intended for the skin before it's opened, applied once per the labeled directions. Once the first pass is made and the skin barrier is broken, cream is no longer the right tool. That's the point to apply Elite Numbing Gel, a secondary anesthetic intended for open tissue — also applied once, following the same labeled directions. We cover the full protocol, plus the exact difference between the two formulas, in Numbing Cream vs. Numbing Gel and Primary vs. Secondary Numbing: A Step-by-Step Guide.
Frequently asked questions
Is numbing cream the same as a local anesthetic injection?
No. Injectable local anesthetics are delivered under the skin with a needle and act faster and more deeply. Topical numbing cream works only at the surface and superficial nerve endings, which is why it needs longer contact time and why sensation can still register more deeply in the tissue during a PMU procedure.
Does numbing cream stop all sensation, or just pain?
Most clients still feel pressure, vibration, or a "scratching" sensation from the needle — lidocaine blocks the nerve pathway that registers sharp pain specifically, not all tactile sensation. This is normal and doesn't mean the cream isn't working.
Can numbing cream be used on any skin type?
Most clients tolerate lidocaine-based cream well, but the label specifically excludes use in the eyes, on deep or puncture wounds, on serious burns, or on infected skin, and directs users with heart disease, liver disease, or a history of allergic reactions to local anesthetics to ask a doctor first — screen for these at consultation, not on the treatment table.
How often can numbing cream be used?
Per the product's labeled directions, not more than once every 24 hours.
