Learning with Lyrics! on Instagram: "So how do tattoos ACTUALLY stick around forever? 🤔 Tattoos last because ink is injected deep into the dermis, the stable layer of skin beneath the outer epidermis that constantly sheds. The body's immune cells (macrophages) try to remove the foreign ink but can't, so they engulf the large pigment particles and get stuck, essentially trapping the ink in the dermis, allowing it to remain visible! #science #tattoo #tattooed #tattoos #tattooing"
