Anesthesia for tattoos in Buenos Aires can vary depending on the studio and the complexity of the procedure. While local anesthesia (such as lidocaine) is commonly used for tattooing, its cost is usually included in the price of the tattoo session. Prices for tattoos in Buenos Aires generally range from $50 to $100 per hour. However, if you're specifically seeking anesthesia as a separate charge, it's best to confirm directly with the tattoo studio, as the cost may differ based on factors like the location and the artist's experience.
