Tattoo Numbing Creams

Do They Work, Are They Safe and Do They Affect Tattoos?

Tattoo numbing creams have become increasingly popular, particularly for long sessions, sensitive placements and clients who are nervous about pain.

Some people describe them as a game-changer. Others say the cream stopped working halfway through the appointment or made the skin difficult to tattoo. Tattoo artists also have different opinions: some are comfortable working with certain products, while others prefer clients not to use them at all.

So, do tattoo numbing creams genuinely work? How long do they last? Does the tattoo hurt more when the numbness wears off? Can you overdose on lidocaine? And can numbing cream affect the final tattoo?

This guide explains what clients and tattoo artists need to know in straightforward language.

Important: This article provides general information and is not medical advice. Always follow the instructions supplied with the product and speak to a pharmacist or medical professional when unsure.

Do tattoo numbing creams actually work?

Yes, legitimate topical anaesthetic creams can reduce pain at the surface of the skin.

Common active ingredients include:

• Lidocaine

• Prilocaine

• Tetracaine

• Benzocaine

These ingredients temporarily interrupt the pain signals travelling through nerves in the treated area. However, they do not necessarily remove every sensation.

A person may still feel:

• Pressure

• Vibration from the tattoo machine

• Pulling or stretching

• Deeper discomfort

• Sensitivity in areas where the cream did not absorb evenly

For this reason, numbing cream should reduce discomfort rather than be expected to make every tattoo completely painless.

Recognised medical products are normally intended for specific uses, amounts, application times and areas of skin. For example, EMLA contains 2.5% lidocaine and 2.5% prilocaine and generally requires between one and two hours to produce reliable anaesthesia on intact skin. LMX4 contains 4% lidocaine and is designed to provide surface anaesthesia on intact skin.

How long does tattoo numbing cream take to work?

The timing depends on the product, the active ingredient, the part of the body and how it is applied.

Some products begin working within approximately 20 to 30 minutes. Others need at least one hour.

As a general guide:

Product or ingredient	Typical preparation time	Important point
Lidocaine cream	Approximately 30–60 minutes	Timing varies considerably between products
Lidocaine and prilocaine cream	Approximately 60–120 minutes	Usually needs to remain on intact skin for longer
Tetracaine gel	Approximately 30–45 minutes	May cause noticeable redness
Unregulated online products	Unknown	The label may not accurately reflect the contents

These times are not interchangeable. Always follow the instructions for the exact product being used.

Applying more cream does not necessarily make it work faster. Leaving it on longer than instructed can also increase absorption and the risk of side effects.

How long does numbing cream last during a tattoo?

There is no single answer.

Depending on the product and the person, the useful numbing effect may last from around one hour to several hours. It can also begin fading soon after the cream is removed.

The duration may be affected by:

• The active ingredients and their concentrations

• How long the cream was left on

• The amount applied

• The size and location of the treated area

• Skin thickness

• Blood circulation

• Whether the area was covered

• Individual metabolism

• How heavily the skin is worked during the tattoo

A cream that works well for a small tattoo may not remain effective throughout a full-day session.

The tattoo artist will also clean the skin repeatedly. Once tattooing begins, the skin becomes irritated and broken, so applying more of a product that was only designed for intact skin may be unsafe.

What happens when the numbing cream wears off?

The feeling normally returns gradually, although it can sometimes seem sudden.

A person may notice:

• Tingling

• Increasing warmth

• Stinging

• Burning

• Normal tattoo pain returning

• Tenderness from skin that has already been tattooed

By this point, the skin may have been worked for an hour or longer. It is therefore already irritated and inflamed.

This can make the returning discomfort feel intense, particularly when compared with the near-numb sensation experienced moments earlier.

Does it hurt more after the numbing cream wears off?

Not necessarily.

There is not strong evidence that correctly used numbing cream permanently makes the nerves more sensitive or automatically causes the tattoo to become more painful than it otherwise would have been.

However, it can feel worse for several practical reasons.

First, there is a strong contrast between feeling very little and suddenly feeling a tattoo needle again.

Second, the tattooed area is no longer fresh. It may already be swollen, inflamed and tender by the time sensation returns.

Third, without numbing cream, discomfort usually increases gradually. When numbness fades, the person may experience the pain at a later and more irritated stage of the tattoo.

This is sometimes described as “rebound pain”, although that does not mean the cream has damaged the nerves. In many cases, it is the normal pain from already-worked skin becoming noticeable as the anaesthetic effect disappears.

Can numbing cream make the skin harder to tattoo?

It can, although the effect varies between products and clients.

Some numbing creams temporarily change the appearance or texture of the skin. Recognised product information lists reactions including:

• Blanching or whitening

• Redness

• Mild swelling

• Itching

• Temporary skin thickening

• Local irritation

Tetracaine products may cause redness because tetracaine widens small blood vessels near the skin’s surface. Lidocaine and prilocaine products may cause temporary whitening, redness or changes related to hydration under the covering.

From an artist’s perspective, treated skin may sometimes feel:

• Soft or spongy

• Rubbery

• Overhydrated

• Slippery

• Swollen

• Unusually firm

• More difficult to stretch consistently

Tattooing relies on controlled skin tension and consistent needle depth. When the texture changes, precise linework, smooth shading and solid colour packing may become more difficult.

This does not happen to everyone, and experienced artists may be comfortable working with certain products. However, it explains why clients should always speak to their artist before applying anything.

Does numbing cream stop tattoo ink from going into the skin?

There is not good evidence that every correctly used numbing cream automatically prevents tattoo ink from entering the skin.

Claims that numbing cream always “rejects ink” or completely ruins tattoos are too broad.

However, temporary skin changes can make tattooing more difficult. If the skin becomes swollen, unusually soft or difficult to stretch, the artist may find it harder to maintain consistent needle depth.

Possible technical problems could include:

• Patchy saturation

• Uneven colour

• Less precise lines

• Additional passes over the same area

• Increased skin trauma

• Greater difficulty judging irritation

The product itself may also leave an oily or slippery residue if it is not removed thoroughly. This can interfere with stencil application or cause the stencil to wipe away more easily.

The main concern is therefore not that lidocaine chemically pushes ink out of the skin. It is that certain products or application methods can change the working surface.

Can numbing cream affect tattoo healing?

A recognised product used correctly on intact skin does not automatically cause poor healing.

However, healing may be affected when the skin experiences:

• An allergic reaction

• Significant redness or swelling

• Blistering

• Chemical irritation

• Excessive occlusion and moisture

• Additional trauma caused by difficult tattooing

• Contamination from an unsuitable product

• Reapplication of a non-sterile product to broken skin

If the skin is already irritated before tattooing begins, it may be more vulnerable to further trauma.

There is currently much stronger evidence regarding temporary skin reactions and anaesthetic toxicity than there is regarding permanent changes to healed tattoo ink. Clients should be cautious of both extreme claims: numbing cream is neither completely risk-free nor guaranteed to ruin a tattoo.

Is lidocaine dangerous?

Lidocaine is a widely used local anaesthetic. When used correctly and within the instructions of an authorised product, it is generally considered effective and well tolerated.

However, lidocaine is still a medicine.

Too much lidocaine can enter the bloodstream, particularly when it is:

• Applied over a large area

• Applied in a very thick layer

• Left on longer than directed

• Used repeatedly

• Applied to irritated or broken skin

• Covered in a way that increases absorption

• Combined with another product containing lidocaine

• Mixed with other local anaesthetics

• Used alongside certain medicines or medical conditions

The FDA has warned that high-concentration topical anaesthetic products marketed for tattoos and cosmetic procedures can cause serious problems, including irregular heart rhythms, seizures and breathing difficulties. It specifically warns against heavy application over large areas, use on irritated or broken skin and wrapping products unless the instructions permit it.

Can you overdose on tattoo numbing cream?

Yes.

An overdose does not require someone to swallow the cream. Local anaesthetic can be absorbed through the skin and enter the bloodstream.

This is known as local anaesthetic systemic toxicity. It is uncommon, but it can be life-threatening.

Early warning signs can include:

• Tingling or numbness around the mouth

• A metallic or unusual taste

• Ringing in the ears

• Dizziness

• Confusion

• Blurred vision

• Slurred speech

• Unusual agitation

• Muscle twitching

• Nausea

More severe poisoning can cause:

• Seizures

• Breathing difficulties

• Dangerous changes in heart rhythm

• Low blood pressure

• Collapse

• Cardiac arrest

If a client becomes confused, collapses, has a seizure, experiences breathing difficulties or develops a dangerous-looking reaction, stop the procedure and call emergency services.

Why is mixing numbing creams dangerous?

Different products may contain the same active ingredient under different brand names.

For example, someone may apply:

1. A lidocaine cream before the appointment

2. A second cream containing lidocaine and prilocaine

3. A numbing spray during the tattoo

4. A gel containing tetracaine or another anaesthetic

The person may think they have used several separate products, but their body experiences the combined amount of all the anaesthetic ingredients.

The toxic effects of lidocaine and prilocaine can be additive. This means combining them can increase the overall risk rather than keeping each product within a separate safe allowance.

Never mix numbing creams, sprays or gels unless a qualified medical professional has specifically confirmed that the combination and doses are appropriate.

Products containing several “-caine” ingredients should be treated with particular caution.

What is prilocaine, and what is methemoglobinaemia?

Prilocaine is another local anaesthetic. It is often combined with lidocaine, including in products such as EMLA.

In excessive amounts or in susceptible individuals, prilocaine can contribute to a rare but serious condition called methemoglobinaemia.

This changes the haemoglobin in the blood so that it cannot carry oxygen normally.

Warning signs can include:

• Grey or blue lips

• Grey or blue skin

• Breathlessness

• Headache

• Dizziness

• Unusual tiredness

• Rapid heartbeat

• Confusion

This requires urgent medical assessment.

The risk may be higher in certain infants, people with particular blood disorders and people taking medicines that also increase the risk of methemoglobinaemia. The EMLA product information explains that methaemoglobin formation is associated with the cumulative amount of prilocaine absorbed.

What about tetracaine and benzocaine?

Tetracaine is a powerful local anaesthetic used in products such as Ametop. It can produce redness because it widens small surface blood vessels.

Repeated exposure can also increase the risk of sensitisation, meaning a person may develop an allergic reaction after previous uses without a problem. The official Ametop information states that it should not be mixed with other medicines in the absence of compatibility studies.

Benzocaine is another topical anaesthetic. It is more commonly found in products intended for the mouth or mucous membranes than in standard tattoo creams.

Benzocaine has also been associated with methemoglobinaemia. It should not be casually added to a routine involving other numbing products.

Are very high-strength online creams safe?

A higher percentage does not automatically mean a better product.

Some creams sold online make claims such as:

• 10% lidocaine

• 20% lidocaine

• 30% lidocaine

• 40% numbing strength

• Completely painless for six or eight hours

• Safe for repeated use on broken skin

These claims should be treated cautiously.

The percentage may not be reliable, and the product may not have been authorised or tested to the same standard as a UK pharmacy medicine.

In March 2024, the FDA warned consumers about several topical pain-relief products marketed for tattooing and other cosmetic procedures. Some claimed concentrations above those permitted for over-the-counter topical pain relief products, including products marketed as containing 10%, 29.9% or “40%” lidocaine or numbing ingredients.

Online packaging can also be copied. Two boxes that look identical may not necessarily contain the same formulation.

Can numbing cream be applied again during the tattoo?

Do not assume that a product suitable for intact skin is suitable for freshly tattooed skin.

Once tattooing begins, the skin barrier has been broken. Medication can then be absorbed differently and potentially more quickly.

There is also an infection-control concern. A multi-use cream, pump, spray or tube may not be sterile.

Unless the exact product is authorised and clearly instructed for use on broken skin, it should not be reapplied during the tattoo.

Should numbing cream be covered with cling film?

Only when the instructions for that specific product say it should be covered.

Some recognised creams are designed for use under an occlusive dressing. Covering them helps prevent drying and can improve absorption.

Other products are not intended to be wrapped.

Wrapping the skin can increase absorption. Heat, a large treatment area, a thick application and prolonged covering can increase it further.

The FDA advises consumers not to wrap skin treated with over-the-counter pain-relief products unless directed, because this can increase the chance of serious side effects.

“Everyone on TikTok wraps it” is not a safe substitute for the product instructions.

Who should speak to a pharmacist or doctor before using numbing cream?

Extra caution may be needed for anyone who:

• Has previously reacted to a local anaesthetic

• Has heart rhythm problems

• Has serious liver disease

• Has epilepsy

• Has a blood or haemoglobin disorder

• Has G6PD deficiency

• Is pregnant or breastfeeding

• Takes anti-arrhythmic medication

• Takes medicines that may affect methaemoglobin levels

• Has eczema, dermatitis, cuts or damaged skin in the area

• Plans to treat a very large tattoo area

• Wants to combine more than one numbing product

A pharmacist can check the ingredients, instructions and possible interactions.

Tattoo numbing cream myths and facts

Myth: More cream means stronger numbing

Fact: Using too much can increase absorption and toxicity. Follow the measured amount in the instructions.

Myth: A cream labelled 40% must be better than a 4% pharmacy cream

Fact: The claim may be misleading, unverified or unsafe. A recognised formulation with clear dosing information is more trustworthy than an extreme percentage printed on an online box.

Myth: Numbing cream makes every tattoo completely painless

Fact: It mainly affects surface pain. Pressure, vibration and deeper discomfort may remain.

Myth: The pain always becomes worse after the cream wears off

Fact: It may feel more intense because the skin has already been tattooed and the contrast is sudden. This does not automatically mean the cream damaged the nerves.

Myth: Numbing cream always ruins the ink

Fact: There is insufficient evidence for that blanket claim. However, some products can temporarily change skin texture, swelling, moisture and blood flow, which may make the artist’s job more difficult.

Myth: Different numbing products can be safely layered

Fact: Their ingredients and toxic effects may add together. Mixing products is one of the most avoidable risks.

Our advice before using numbing cream for a tattoo

Speak to your artist before the appointment.

Tell them:

• The exact product name

• Its active ingredients

• The percentage of each ingredient

• How much you plan to use

• When you intend to apply it

• Whether the instructions require covering

• Whether you have used it before

Do not arrive with an unknown cream already applied without telling the artist. Your artist needs to know what is on your skin and may need to assess whether the skin is suitable to tattoo.

At Hammersmith Tattoo London, client safety and the quality of the finished tattoo come first.

An artist may decline to work over skin that appears excessively swollen, irritated, damaged or affected by an unknown product.

Preparing for a tattoo without numbing cream

Numbing cream is not the only way to make a session easier.

Before your appointment:

• Get a proper night’s sleep

• Eat a substantial meal

• Drink enough water

• Avoid alcohol

• Avoid recreational drugs

• Wear comfortable clothing

• Bring a sugary drink or snack when appropriate

• Tell your artist when you need a short break

• Consider splitting a very long project into shorter sessions

Being rested, hydrated and properly fed can significantly improve how well you manage the appointment.

Frequently asked questions

Can I use numbing cream before every tattoo?

Some people use it repeatedly without difficulty, but repeated exposure can increase the risk of skin sensitivity or allergic reactions to certain ingredients. Ask your artist and follow the medical product instructions.

Can I use numbing cream for a full-day tattoo?

The effect may not last throughout a full-day session. Using additional products or repeatedly reapplying cream can increase risk. Discuss session length and pain-management options with your artist beforehand.

Can I apply numbing cream at the tattoo studio?

That depends on the product and the studio’s policy. Many creams require considerable preparation time, so discuss this in advance rather than bringing an unknown product on the day.

What should I do if the cream burns?

A slight temporary sensation may occur with some products, but strong burning, blistering, rapidly increasing redness or swelling is not something to ignore. Remove the product and seek medical advice when necessary.

Can I tattoo over an allergic reaction to numbing cream?

No. Irritated, blistered, swollen or damaged skin should not be tattooed.

Is lidocaine allergy common?

True allergy to lidocaine is considered uncommon, but reactions can occur to lidocaine or to preservatives and other ingredients in the product. Previous successful use does not guarantee that a future reaction is impossible.

Can I use two weaker creams instead of one strong cream?

No. Combining products can still produce a high total dose and may combine different anaesthetics.

Should I buy tattoo numbing cream from an online marketplace?

Use caution. Choose a recognisable, properly labelled product from a legitimate pharmacy or regulated supplier. Avoid products with unclear manufacturers, extreme percentage claims or missing instructions.

Final thoughts

Tattoo numbing creams can work, and when an appropriate product is used correctly, they may make certain tattoos more manageable.

However, they are medicines rather than ordinary skincare products.

The greatest risks come from using too much, treating large areas, applying cream to broken skin, leaving it on too long, wrapping it incorrectly, mixing several products or buying unverified high-strength creams online.

Numbing cream may also temporarily change the colour, moisture, swelling and texture of the skin. That can affect how easily the artist can stretch and tattoo the area, even though there is not strong evidence that every correctly used product automatically ruins ink or healing.

Always discuss numbing cream with your tattoo artist before applying it. For personalised medical advice, speak to a pharmacist, GP or another qualified healthcare professional.
