Permanent or semi-permanent makeup is a cosmetic technique that consists of putting mineral or organic pigments into the superficial skin layer called the dermis. This allows the pigments to stay on the skin for a long period, usually around 12 to 18 months. As we teach in our eyebrow tattoo training, permanent makeup can be used to shape the eyebrows and improve their appearance, to line the lips or the eyes, and even to reconstruct the appearance of the areola and nipple after a mastectomy.
