Corey steps on a tack that pierces the skin of his foot. The order the tack would go through the layers of the skin will be: first the epidermis, then the dermis, and then the hypodermis. 
The outermost layer of skin that provides a waterproof barrier and creates our skin tone is called Epidermis. The part beneath the epidermis which contains tough connective tissue, hair follicles, and sweat glands is known as the dermis. The last layer is made of fat and connective tissue is called the hypodermis.
