The video uses humor and a mnemonic to teach the layers of the epidermis. It begins with a playful introduction about cornflakes and their supposed benefits for youthful skin. The video then explains the three main layers of the skin, focusing on the epidermis and its five sub-layers: stratum basale, stratum spinosum, stratum granulosum, stratum lucidum, and stratum corneum. A mnemonic, 'British and Spanish grannies love cornflakes,' is introduced to help memorize these layers. The video concludes with a humorous note about breakfast.
