The Do No Harm Tattoo is a new type of tattoo that is said to be completely safe and painless. The tattoo works by using a small amount of electricity to stimulate the skin and cause it to produce collagen. This collagen then fills in the area where the tattoo was applied, creating a permanent mark. The electric current also helps to reduce inflammation and promote healing. There are no needles involved in this process, so it is completely safe for all skin types.
