Our skin is the largest organ in our bodies, with a surface area of about 20 square feet in adults.
When we are cut or wounded, our skin begins to repair itself through a complex, well-coordinated process.
Sarthak Sinha takes us past the epidermis and into the dermis to investigate this regenerative response.
