Topical anesthesia is needed for common procedures such as suturing, wound cleaning, injection administration, cosmetic and laser procedures, tattooing, etc. The ideal topical anesthetic would provide complete anesthesia following a simple pain-free application, not contain narcotics or controlled substances, and be safe to use. The most popular local anesthetics used include: Lignocaine (lidocaine), benzocaine, tetracaine (amethocaine) and prilocaine.
One of the most common local anesthetics produced by our laboratory include a combination of the topical anesthetics lidocaine and tetracaine in addition to epinephrine which is a vasoconstrictor. This gel is known as LET Anesthetic Gel. It has been used to treat pain associated with lacerations and for cosmetic procedures where the skin may be broken such as cosmetic or regular tattooing. The vasoconstrictor helps control swelling and bleeding. The onset of action is usually 20 to 30 minutes after being applied. LET Gel is available online here.
A triple-anesthetic gel containing benzocaine, lidocaine, and tetracaine (BLT Gel) has also been reported to be effective when applied prior to laser procedures. Convenience of application without need for occlusion is an advantage of this topical anesthetic gel in addition to a rapid onset of action of 20 to 30 minutes compared to 1 to 2 hours often observed with EMLA cream. The following article reported that a triple-anesthetic gel containing benzocaine, lidocaine, and tetracaine ("BLT") applied prior to treatment with a 532-nm KTP laser resulted in significantly lower pain scores than with 3 other topical anesthetics at 15, 30, 45, and 60 minutes after application (1). BLT cream is available online here.
Due to the increased risk of developing methemoglobinemia (altered haemoglobin) with Benzocaine when applied to large areas we also offer a PLT Gel which contains Prilocaine, Lidocaine and Tetracaine. PLT Gel is available online here.
Our lab also produces a lidocaine and prilocaine combination (similar to EMLA) however LET, PLT and BLT gels are generally considered superior due to a more rapid onset of action and they do not require occlusion.
We supply an over the counter range of local anesthetic gels specifically formulated, with the input of industry members, for cosmetic tattooists. The range includes a general pre-numbing lidocaine gel, an eyelid LT gel and a lip and eyebrow LET gel which also contains a vasoconstrictor to help prevent bleeding. They have been formulated and pH adjusted to prevent burning. Our cosmetic tattoo anesthetic range is available here.
