What makes tattoos permanent? - Claudia Aguirre

Why do tattoos stay on the skin even though skin cells are constantly shed?

• Tattoo ink is absorbed by blood vessels.

• The ink is placed deeper than the shedding layer of skin.

• Skin cells stop shedding where a tattoo is placed.

• Tattoos are made with special ink that doesn't shed.

What is the body's first response when a tattoo needle penetrates the skin?

• The skin immediately starts to shed the ink.

• The body begins an inflammatory process to repair the wound.

• Blood vessels close off to prevent ink from spreading.

• Nerves in the dermis stop sending pain signals.

Which types of cells help keep tattoo ink visible in the skin?

• Epidermal cells and blood cells.

• Nerve cells and glands.

• Macrophages and fibroblasts.

• Collagen fibers and blood vessels.

How does a laser remove a tattoo?

• It burns off the top layer of skin containing the tattoo.

• It uses heat to melt the ink and make it disappear.

• It breaks the ink into smaller particles that immune cells can clear away.

• It changes the color of the ink so it's no longer visible.
