SPMU COUTURE ALLROUND LIPS TRAININGTHE WORKING METHODS Semi permanent make up or SPMU is the introduction of pigments into the dermis. This is done in combination with a special PMU device in which a needle hygiene module is placed. In terms of technique, it resembles a tattoo, but the goal and the products of this treatment are different. A tattoo is placed in a deeper skin layer and is therefore permanent. Semi permanent makeup is a safe way to beautify your eyebrows, eyes or lips.
