Unlike permanent tattoos that inject pigment into the dermis, this technique injects pigment only into the epidermis to precisely define lines. It uses natural pigments that do not change color and gradually fade over 1 to 3 years, hence it's called semi-permanent makeup or microblading.Line Permanent Makeup Center, with a collaborative system between Line Dermatology medical staff and experienced permanent makeup artists, uses natural pigments suited for your skin, hair, and eyebrow hair, and uses disposable tools for a safer procedure.
