Yes, getting a tattoo on your body is going to hurt regardless of the machine type. A tattoo is created by modifying your skin using needles. That specific needle pierces into your skin at around 10-15 drops a second, which is quick enough to stop the skin from getting punctured and bleeding. Our body skin has three layers called the epidermis, dermis, and hypodermis. The top layer or epidermis keeps healing itself. So, the needle has to pierce the dermis or middle layer to make a permanent tattoo. Therefore, the tattooing process can hurt you based on how big and intricate the tattoo design is. You may feel the coil ones on your skin more than the rotary machines. However, the rotary tattoo machine would need more repetitions than the coil ones.
