The pathophysiology of acne. Water makes up 60% of our body weight. Fluid losses greater than 15% are usually fatal. Let me ask you a question. Which organ prevents the sun, from absorbing all of our body water? Yes, it is the skin. Outer layer of the skin, epidermis is somewhat waterproof, due to the hard keratin layer. But it isn't enough to beat the sun. The dermis of the skin, contains sebaceous glands. It secretes sebum on to the epidermis to further waterproof the skin. Can you guess, what substance gives the waterproof ability to sebum Have you noticed, how hard it is to remove oil with water? Thats because the lipid is so hydrophobic. So there's no wonder Sebum is full of lipids, mainly the try-glycerides. Sebaceous glands open into hair follicles, and from there, seebum reach the surface of the skin. Sebum also carries the dead skin cells out of the follicles. Everything works fine when you are a child. But when you hit puberty, testosterone levels increase suddenly. Unfortunately Testosterone, increase the sebum production. But this is not enough to produce acne. There's a protein called keratin, in the skin cells. Some people produce this protein, excessively due to genetic predispositions. We call this hyperkeratinization. High keratin content in the dead skin cells, glues the dead cells to one another. The mixture of high sebum and keratins, block the hair follicle, giving rise to comidones. If the comidones are protected by the skin, we notice the white lipid substance in acne. Thats what we call white heads. But if the skin cover is lost, the melanin in the comidone is oxidized to become darker. We call them the black heads. We all know too much lipid is bad for our health. but the bacteria, Propionibacterium acnes doesn't seem to know that. It grows rapidly in the lipid rich comidones. The bacteria initiates an inflammatory response and further expands the comidones. When they inflame the dermis, we get nodules, or the typical pimples. If the inflammation expands deep into the dermis, where the nerve roots lie, We call them acne cysts. They are larger than the pimples, and they are painful because they are incontact with the nerve roots, and because of the heavy inflammation they often cause scars. The reason for the scar is destruction of collagen and elastin, thus making a skin depression. Now You should understand that acne vulgaris is multifactorial. Treatment options vary from, agents reducing the seebum production ,to agents removing the plugs of the clogged follicles, to agents which are antibacterial and anti-inflammatory. I'll discuss the treatment options in another video. See you soon, but don't forget to subscribe. Music Attribution: Royalty Free Music from Bensound Music: www.bensound.com [-3kHwM7e4ug] |
