As you may already be aware, there is a rise in people seeking stronger anathetics for use in PMU/Tattoo procedures. This comes with great risk, and depending on your particular regulations, may be illegal.
In most of the US, we are permitted to use 4% lidocaine in our numbing products as this is considered OTC strength. Many artists are getting stronger formulations either from other countries, doctors or compound pharmacies. Aside from this being ilegal (we are tattoo artists and it is out of our scope to prescribe or administer medications to our clients” it can be extremely dangerous and fatal.

I am not a medical professional, so the following information is general in nature and should not substitute for guidance from a healthcare provider familiar with your specific circumstances. That said, here is an overview of key considerations regarding the use of topical anesthetics containing lidocaine in concentrations higher than 4% in the context of tattooing or permanent makeup.
Why Tattoo and Permanent Makeup Artists Should Stick to OTC Lidocaine Numbing Products
In the world of tattooing and permanent makeup (PMU), the comfort and safety of clients are top priorities. As an artist, you’ve likely used topical anesthetics to minimize discomfort. While you may come across or hear about higher-concentration lidocaine products from compounding pharmacies or physicians, it’s important to understand the risks and potential legal implications of using them. In most cases, the standard OTC 4% lidocaine creams and gels are the safest and most appropriate option for non-medical professionals.
Understanding Lidocaine and Its Purpose
Lidocaine is a local anesthetic widely used to numb specific areas on the skin. Its primary goal is to help minimize pain or discomfort during procedures like tattooing or permanent makeup. Because it can be absorbed into the bloodstream, using higher-than-necessary concentrations or large amounts can increase the risk of systemic toxicity, which can lead to serious medical complications.
The Risks of Going Above 4% Lidocaine
Over-the-counter lidocaine is typically 2–4% in strength, and even at these concentrations, artists must use caution regarding how much is applied and over what surface area.
When lidocaine percentages exceed 4%, the margin for error narrows significantly. If the skin barrier is broken or if large areas of the body are treated, higher concentrations can cause more lidocaine to enter the bloodstream and lead to lidocaine toxicity or “lidocaine poisoning.” The signs of toxicity may include:
Dizziness or lightheadedness
Numbness around the mouth
Ringing in the ears (tinnitus)
Muscle twitching or tremors
Seizures (in severe cases)
Irregular heartbeat or cardiac complications
Such adverse events can escalate quickly, putting both client and artist in a dangerous and avoidable situation.
Liability and Licensing Issues
Beyond the health risks, using prescription-strength anesthetics or specially compounded creams raises legal and regulatory concerns:
Prescription Medications: If the product is not approved for over-the-counter use, you are essentially administering a prescription medication without being a licensed medical provider. This can lead to legal consequences and liability issues.
Insurance Coverage: Certain liability insurance policies for tattoo and PMU artists may not cover complications arising from using non-OTC products. If an adverse event occurs, you risk not being covered.
Regulatory Scrutiny: Many states and countries have specific rules governing who can administer prescription-strength or compounded anesthetics. Going beyond 4% lidocaine can trigger regulatory attention if you are not properly licensed.
Benefits of Sticking to OTC Solutions
Safety Margin:
Over-the-counter lidocaine formulations (4% or lower) are designed with a relatively broader safety margin for short procedures. When used correctly, the risk of serious adverse events is lower.Compliance with Guidelines:
Using products that are approved for OTC sale helps ensure you remain within the bounds of local regulations and professional guidelines.Client Peace of Mind:
Clients often appreciate that you’re using a recognized, common product with established safety records. This can increase their confidence and comfort in your services.Professional Reputation:
Steering clear of unnecessary medical-grade products or prescriptions helps protect your reputation as an ethical, safety-conscious artist.
Practical Tips for Safe Use of OTC Lidocaine
Follow the Label: Always read and adhere to the instructions regarding the maximum recommended area of application and the duration for which the product can remain on the skin.
Use the Minimal Effective Amount: Apply just enough to cover the area effectively. More is not always better, especially with anesthetics.
Spot Check: If your client has never used lidocaine before, consider a small patch test to rule out any potential allergic reaction.
Monitor Client Comfort: Keep an eye on how your client is feeling throughout the procedure. Stop if they experience unusual symptoms like nausea, dizziness, or a racing heart.
Educate Your Client: Let them know the expected numbness duration and advise them to speak up if they feel any unusual sensations.
When in Doubt, Ask a Professional
If you or your client have specific medical concerns—whether it’s a health condition or a unique sensitivity—advise them to consult with a licensed medical professional before using any numbing product. It is not your responsibility, nor is it within your scope of practice as a tattoo or PMU artist, to diagnose medical conditions or prescribe medication.
Your client’s safety and comfort should always guide your choice of topical anesthetics. While prescription-strength lidocaine or compounded creams might seem appealing, they significantly raise the risk of adverse events and legal complications for non-medical professionals. Over-the-counter 4% lidocaine products, used correctly and within guidelines, are typically the best choice for tattoo and PMU procedures. By sticking to these safer, properly regulated options, you protect your clients, your reputation, and your practice.

Understanding Lidocaine Toxicity (Lidocaine Poisoning)
What is lidocaine toxicity?
Lidocaine toxicity (or lidocaine poisoning) occurs when the drug accumulates in the bloodstream at levels high enough to cause harmful systemic effects. When lidocaine is applied to skin (especially in large areas or with damaged skin), some of the medication is absorbed into the bloodstream. If the concentration is too high, or if too large a surface area is treated, or if the duration of contact is prolonged, the total absorbed dose can exceed safe limits.
Signs and symptoms of systemic lidocaine toxicity can include:
Central Nervous System (CNS) Symptoms:
Numbness around the mouth or tongue
Dizziness, lightheadedness
Tinnitus (ringing in the ears)
Blurred vision or difficulty focusing
Tremors, muscle twitching
Confusion or drowsiness
Seizures (in severe cases)
Cardiovascular Symptoms:
Bradycardia (slow heart rate) or tachycardia (fast heart rate)
Hypotension (low blood pressure)
Arrhythmias
Cardiac arrest (in severe, life-threatening cases)
Because these symptoms may escalate rapidly, it’s crucial to recognize early signs and discontinue application of the topical anesthetic if toxicity is suspected.
Why 4% is Often Used as a Reference Point
Many over-the-counter (OTC) and prescription-strength topical lidocaine creams are formulated at 2–4%. In a clinical setting, higher concentrations can be used; however, they usually come with explicit guidelines regarding:
Maximum Recommended Dose: Often based on the patient’s body weight.
Surface Area Coverage: Some recommendations limit the amount of skin that can be safely treated at one time.
Application Time: Prolonged application can increase systemic absorption.
The reason 4% is a common benchmark is that at or below this concentration, there’s often a wider margin of safety for short applications, even if you accidentally apply a bit more than intended—though every case is individual and can still pose risks if misused.
Safety Concerns for Tattoo Anesthetics Above 4%
Increased Systemic Absorption:
Higher concentrations (e.g., 5%, 10%, or compounded solutions) can significantly raise the risk of lidocaine entering the bloodstream at levels that lead to toxicity.
This is especially concerning in tattoo or permanent makeup procedures where the skin barrier may be broken or compromised, allowing even greater systemic absorption.
Large Treatment Areas:
Tattoo sessions often involve relatively large surface areas for extended periods. If a product above 4% is used across a large area or frequently reapplied, systemic absorption can exceed safe limits.
Client Variability:
Weight, age, health status, and individual metabolic differences can influence how quickly lidocaine is processed by the body. A dose that is safe for one person could be risky for another (e.g., smaller individuals, those with liver conditions, or those on certain medications).
Cumulative Effect:
If multiple anesthetic products (some containing epinephrine or different active agents) are used in a single session, total exposure could become unsafe even if each individual product is within recommended limits.
Inaccurate Estimation of Dose:
Topical application can make it challenging to estimate exactly how much lidocaine was absorbed, unlike the more controlled measurement of an injectable dose.
Practical Precautions
Consult Manufacturer Guidelines: Always refer to the product’s instructions and any safety bulletins provided by the manufacturer regarding maximum recommended dosage or area coverage.
Minimize Treatment Area: Keep application localized and avoid applying high-concentration lidocaine cream to unnecessarily large areas of skin.
Use the Shortest Effective Contact Time: The longer the contact time, the more the drug is absorbed.
Monitor the Client: Watch for early signs of lidocaine toxicity—CNS symptoms often appear first. If the client reports or shows any unusual reactions, stop and seek medical advice.
Consider Compounding Pharmacy Advice: If you’re considering or using a pharmacy-compounded product at a concentration above 4%, consult with the pharmacist about recommended usage guidelines and safe dosage limits.
Have an Emergency Plan: Especially important in any setting using local anesthetics. Be prepared with equipment and procedures for managing potential adverse events (e.g., seizures, severe allergic reactions).
When in Doubt
Seek Professional Medical Input: A healthcare provider or pharmacist can give you a clear picture of safe lidocaine dosing, particularly if you’re dealing with clients who have unique risk factors (e.g., heart conditions, compromised liver function, or those on specific medications).
Verify Regulatory Guidance: In many regions, there are regulations or guidelines on maximum OTC lidocaine concentrations (often capping at 4 or 5%). Exceeding these concentrations might require a prescription or special compounding instructions.
Key Takeaways
Lidocaine toxicity is a serious concern when concentrations exceed 4% or when large amounts are applied.
The risk of toxicity is related to total dose, surface area, individual factors, and duration of exposure.
Adherence to best practices—including monitoring for adverse effects, limiting the surface area, and using the lowest effective concentration—helps reduce risk.
If you have any doubts about a specific product or procedure that uses lidocaine above 4%, it’s best to consult with a medical professional or a pharmacist for clear, personalized guidance.
