A permanent tattoo is a process – where ink is injected into the superficial layer of the skin to create something that stays lifelong with you. Tattoo application uses a mechanized needle to puncture the skin and inject ink into the dermis or second layer of skin just below the epidermis.
This type of tattoo will fade a little with aging but it can’t be removed completely unless you cut your skin deep enough to remove those pigments. However, laser treatments are available these days to remove them.
