I’m an educated skin therapist, and I’m allowing myself to use this platform explaining to you the function of your skin today. You might ask yourself why I’m doing this, and I can assure you that I have a point, please be dear and hang in there. Without further ado, here’s a little guide to the deepest layer of your epidermis.
Our skin has 3 layers – epidermis (upper layer), dermis (middle layer) and Subcutis (bottom layer). For now, I’m only showing you epidermis.
As you can see on the picture above, there’s even more layers in epidermis – five to be precise. The deepest layer called Stratum Basale are the most important layer because this is where cell division happens. We also have 4 different cells being formed here – merkel cells, langerhans cells, melanocytes and keratinocytes.
Merkel cells and langerhans cells are a part of the immune system. Langerhans cells have long threads who catch toxic substances and ship them to the lymphatic system. Keratinocytes exists in all layers of epidermis, they play a defensive part in the skin and they are resistant towards chemicals, humidity, rays and heat.
Last but definitely not least, Stratum Basale contains melanocytes. They produce melanin who’s the most important pigment in our skin. They start producing melanin when UV-rays hits our skin. Melanin hinders the danger of sunburns, and protect chromosomes in the cells further down.
The cause of differentiation between black, yellow, brown and white “races” are mainly caused by uneven contents of melanin. Black people do not necessarily have more melanocytes but the ones they have are more active.
Which leads me to my point: We are four months away from 2020 and humans are killing, bullying and harassing other’s due to their cell production.
Think about it. Tell me what you think.
