Microblading and semi permanent make-up are actually cosmetic tattooing procedures, however the pigment is injected into the upper layer of the skin, the epidermis. This is the outer layer of skin the regenerates constantly, which causes fading and loss of pigment. With tattooing, the pigment penetrates deeper to the lower layers of the skin (dermis), where the cells are much more stable than the cells of the epidermis, causing the pigment to persist/ possibly with slight fading or spillover of pigment/ throughout the lifetime of the individual.
