Is Numbing Cream Safe? Lidocaine Percentages, FDA Guidance & What Artists Should Know
Lidocaine is one of the most studied and widely used local anesthetics in medicine — but "widely used" doesn't mean "use however you like." The FDA has issued specific guidance around topical numbing products, and understanding it is part of running a responsible, professional PMU practice.
Elite Permanent Makeup & Cosmetology College has trained licensed PMU artists in Los Angeles since 2012 and is licensed by the California Bureau for Private Postsecondary Education (BPPE). Last reviewed: August 2026.
Quick answer: Lidocaine numbing cream is a standard, well-established professional PMU tool when applied by a trained artist, to a defined area, for the labeled contact time, on intact skin. The FDA's warnings about high-strength lidocaine target unsupervised consumer products used without guidance — not licensed professionals following a labeled protocol.

What the FDA has actually said
The FDA has warned about the risks of high-strength topical lidocaine products, particularly consumer-facing, over-the-counter products marketed for use before cosmetic procedures like microdermabrasion, laser hair removal, tattooing, and piercing without professional supervision. In its official consumer warning, the agency issued letters to multiple companies for marketing products with lidocaine concentrations higher than what's permitted for OTC topical pain relief, and specifically flagged that applying these products in ways that increase absorption — large surface areas, broken or irritated skin, prolonged occlusion — can lead to serious injury including irregular heartbeat, seizures, and breathing difficulties.
That's a real, documented risk — but it's a risk profile built around unsupervised consumer use of unapproved products, not around a licensed professional following a labeled protocol on a defined treatment area.
What actually increases systemic absorption risk
| Risk factor | Why it matters | In a PMU setting |
|---|---|---|
| Large treatment area | More product, more absorption into the bloodstream | Brows/lips/eyeliner are small relative to FDA-flagged thresholds |
| Broken or irritated skin | Skin barrier no longer limits absorption rate | Primary cream is only ever applied to intact skin |
| Prolonged occlusion | Extended contact time increases total exposure | Labeled dwell time is followed, not extended |
| No trained supervision | No screening for contraindications or reaction monitoring | Licensed artist takes health history and monitors the client |
Why professional-use products are a different context
PMU treatment areas — brows, lips, eyeliner — are small relative to the surface-area thresholds that raise systemic absorption risk. A trained artist applying Elite Numbing Cream to a defined treatment area, for the labeled contact time, on intact skin, on a client with no known contraindications, is operating in a very different risk category than an unsupervised consumer applying an unregulated product to a large area of the body for hours.
That said, "professional use only" is a real limit, not a marketing phrase. It means the product is intended to be applied by someone trained to assess the client, control the treatment area, and follow the labeled protocol — not that the usual precautions don't apply.
What responsible use actually looks like
- Apply only to the intended treatment area, not extended margins "just in case."
- Never apply a primary cream to broken, irritated, or compromised skin — that's what secondary gel is formulated for.
- Follow the labeled contact time. Longer isn't more effective, it just increases exposure.
- Ask every client about known lidocaine or local anesthetic sensitivities before applying anything.
- Stay within your state's scope-of-practice rules for anesthetic use in a PMU setting — these vary by state, and some restrict what license holders can apply.
The bottom line
Lidocaine-based numbing cream is a standard, well-established tool in professional PMU work when it's used the way it's labeled to be used. The FDA warnings that make headlines are almost always about unsupervised, high-concentration consumer products used outside any protocol — not about a trained artist following a professional-strength product's instructions on a defined treatment area.

Frequently asked questions
Is 5% lidocaine too strong for professional use?
5% is a standard professional-strength concentration for topical anesthetics used by trained artists on small, defined treatment areas — different from the unsupervised, high-concentration consumer products the FDA has specifically warned about.
Do I need a license to use numbing cream on clients?
Requirements vary by state. Some states restrict topical anesthetic application to specific license types or require additional certification — check your state's cosmetology or PMU board rules before incorporating numbing into your service menu.
What should I do if a client has a known lidocaine allergy?
Don't apply lidocaine-based products to that client. Document the allergy and discuss alternative approaches or referral with the client before the appointment, not on the treatment table.
Is it safe to use numbing cream on every client?
Most clients tolerate it well, but always screen for known sensitivities, active skin conditions, and relevant medical history at consultation. When in doubt, don't apply and consult your training or a medical professional.
