Yes, Emla 5% Cream is licensed and highly effective for numbing the skin prior to cosmetic needle procedures, including tattooing and laser tattoo removal. It contains two active local anaesthetics—lidocaine and prilocaine—which work together to block pain signals from reaching the brain.
Because Emla is a regulated, MHRA-approved medicine, it offers a safe, predictable alternative to unregulated, black-market import creams frequently found online.
To get the best results from a pharmacy-grade topical anaesthetic like Emla, application timing and technique are critical:
-
Clean the area: Ensure the skin is completely washed, dried, and free of oils or lotions.
-
Apply a thick layer: Squeeze a generous, thick layer of the cream onto the target area. Do not rub it in like normal moisturizer; it needs to sit visibly on top of the skin.
-
Seal it (Occlusion): Cover the cream entirely with an airtight, watertight plastic wrap or film (an occlusive dressing). This stops the cream from drying out and forces the active ingredients into the skin.
-
Wipe clean: Leave the wrap on for 60 minutes before your session. Just before your tattooist starts, remove the dressing and completely wipe off any excess cream.
Once the cream is removed after a full 60-minute application, the localized numbing effect typically lasts for at least 2 hours.
Keep in mind that factors like your skin type, the thickness of the skin in that area, and how well it was sealed under wrap will affect the duration. If you are booking a long, multi-hour session, map out your timing carefully with your artist.
When using licensed UK pharmacy products according to the patient information leaflet, numbing creams are safe for most adults. However, there are strict safety guardrails you must follow to prevent dangerous levels of bloodstream absorption:
Important Safety Limits:
-
Maximum Dose: Never use more than 60g (two 30g tubes) of Emla cream during a single tattoo session or within a 24-hour period. For LMX4, apply the cream at a dosage of approximately 1.5g to 2g LMX4 /10cm2 skin to be treated, or multiples thereof, up to a maximum area of 900cm2. LMX4 must not be reapplied for 12 hours after removal.
-
Intact Skin Only: Only apply numbing cream to healthy, unbroken skin. Never apply it to cuts, scrapes, or active skin conditions.
-
No Reapplication: Do not reapply numbing cream to the skin once the tattooing process has begun and the skin barrier is open.
Always follow the instructions on the Patient Information Leaflet provided with your numbing cream, and speak to your pharmacist if you're unsure or have any questions.
Emla Patient Information Leaflet
LMX4 Patient Information Leaflet
Licensed, water-based pharmacy creams like Emla or LMX4 will not ruin your tattoo or affect ink retention. However, local anaesthetics can temporarily cause vasoconstriction or vasodilation—meaning the skin may look slightly pale, red, or mildly puffy right after the dressing is removed.
Reputable tattoo artists are entirely used to this, but you should always inform your artist beforehand that you have applied a numbing cream so they can account for minor, temporary changes in skin texture.
The online market is saturated with illegal, unregulated imports (often branded as TKTX or similar) that bypass UK medical safety checks. These products often contain dangerously high, unlabelled doses of lidocaine, or are manufactured in unsterile environments, leading to high risks of chemical burns, poor wound healing, and systemic toxicity.
Buying from a GPhC-registered online pharmacy guarantees you are receiving legitimate, clinically tested products stored under strictly regulated conditions.
