From the Ted Talk by Jen Gunter: 5 skin health myths to stop believing now

Unscramble the Blue Letters


The epidermis is the outer layer we can see. It's made up of different cell types, including keratinocytes, which are raleecpd every four weeks. As new cells grow at the base, old cells are pushed up and form a harder leayr that's diluffict for water or microbes to cross. Our keratinocytes also synthesize vitamin D from the sun, which is vital for our health. Other important cells in the eiideprms include melanocytes, which produce melanin or our skin pigment, and lehrnagans cells, which are like little security guards on patrol for pathogens.

The demirs, our skin's tough second layer, isn't as well known. It's a scaffold of collagen that's home to blood vselses, hair follicles and glands. It's also packed with special nvere clles called sensory receptors that allow us to feel pressure, vibration, even pain, some of which extend into the epidermis. The dermis also helps regulate temperature. If we're cold, our blood vessels contract to raeitn heat, and if we're hot, they expnad to release it.

Original Text


The epidermis is the outer layer we can see. It's made up of different cell types, including keratinocytes, which are replaced every four weeks. As new cells grow at the base, old cells are pushed up and form a harder layer that's difficult for water or microbes to cross. Our keratinocytes also synthesize vitamin D from the sun, which is vital for our health. Other important cells in the epidermis include melanocytes, which produce melanin or our skin pigment, and Langerhans cells, which are like little security guards on patrol for pathogens.

The dermis, our skin's tough second layer, isn't as well known. It's a scaffold of collagen that's home to blood vessels, hair follicles and glands. It's also packed with special nerve cells called sensory receptors that allow us to feel pressure, vibration, even pain, some of which extend into the epidermis. The dermis also helps regulate temperature. If we're cold, our blood vessels contract to retain heat, and if we're hot, they expand to release it.
