Permanent makeup is a form of tattooing called cosmetic tattooing.
The specialised techniques are often referred to as micro pigmentation. The implantation technique deposits pigment into the upper reticular layer of the dermis.
Permanent cosmetic procedures are performed using a various devices from a hand held tool for Microblading to a digital rotary machine for Ombre brows.
Permanent cosmetics are considered permanent because pigment is tattooed into the upper layer of the dermis, the same as a regular tattoo. What sets this apart from a regular tattoo is the pigment, which is designed to fade over time.
