They come in different forms, such as creams, gels, sprays, and patches, and are available over the counter or by prescription. The most potent topical anesthetic depends on the type and concentration of the active ingredient, as well as the area of application and individual tolerance.

Lidocaine is a common local anesthetic used in dental, dermatological, and minor surgical procedures. It blocks nerve signals in the affected area, resulting in temporary numbness and pain relief. Lidocaine is available in various forms, such as creams, gels, and sprays, and in different concentrations of up to 5%. It is considered one of the most potent topical anesthetics but should be used cautiously as it can cause allergic reactions and toxicity at high doses.
Benzocaine is another local anesthetic commonly used in dentistry and over-the-counter products such as throat sprays, cough drops, and skin creams. It numbs the affected area’s nerves but is not as potent as lidocaine. Benzocaine is available in concentrations up to 20% and is generally safe when used as directed, but it can cause rare but severe side effects such as methemoglobinemia.
Tetracaine is a potent local anesthetic used in ophthalmology and cosmetic procedures such as laser hair removal and tattoo removal. It blocks nerve impulses and reduces blood flow to the affected area. Tetracaine is available in various forms, including creams and gels, and in concentrations up to 4%. However, it can cause serious side effects such as allergic reactions, corneal damage, and central nervous system toxicity, and it should only be used under medical supervision.
EMLA is a topical anesthetic cream containing a combination of lidocaine and prilocaine. It is commonly used to numb the skin before minor surgical procedures and for pain relief during laser treatment and tattooing. EMLA penetrates the skin and blocks nerve impulses in the affected area. It has various strengths and can be applied under occlusive dressings for enhanced effect. EMLA is considered one of the most potent topical anesthetics available but may cause side effects such as skin irritation and allergic reactions.
