Teprsol is the name of the proprietary fluid that has Tatt2Away developed to aid in ink removal from the skin. Teprsol is 100% organic, vegan, and naturally occurring in the body. A common misconception is that Teprsol is injected into the skin but actually, Teprsol sits on the surface of the abrasion the Tatt2Away device creates to help pull ink up and out of the skin.
