Post Inflammatory Hyperpigmentation PIH Pt I What Causes Those Dark Spots
PIH TEXT Today Bertie and I are going to talk to youabout PIH or Post Inflammatory Hyperpigmentation. Oh, Thanks Bertie! And like the spots on thisegg, PIH produces dark concentrated areas of pigmentation as a response to skin inflammation. Now Bertie's egg comes by its spots naturally,but PIH appears when your immune system overreacts to traumathe skin. Conditions like acne,eczema, psoriasis, and even little things like insect bites (ow!) trigger an inflammatoryresponse that can cause melanin production go bonkers. Since melanin is the brown pigmentthat gives our skin its color, the result
is dark marks and uneven skin tone. Now normally our skin looks a little morelike this. Melanin's job is to give you an even skin tone and protect you from UVradiation. To that, melanin says, â€œYou'reWelcome Americaâ€�. Turn up the sun exposure and skin turns uptyrosinase, an enzyme that kicks melanin production into high gear. Boyaah! To help you better understand, let's take a closer look. When you're exposed to sun, tyrosinase activates melanocytes,
little factories at the base of the epidermis that produce and package melanin granules. These packages travel up towards the keratinocytes, turning you a shade darker and protecting the cells'nucleus from damage. So even when loungingthe sun, your skin is hard at work! Sometimes the body's immune system destroysthe melanocytes, the cells that make the melanin. This condition is called vitiligo, and theresult is patches of depigmented skin. Although it's considered a disorder, people like Chantelle Winnie, contestant from America's Next Top Model, are out to show the worldthat uneven skin, light or dark can still
be beautiful. In skin affected by PIH, inflammation fromeveryday conditions like acne can cause melanin production to go haywire! The immune systemtriggers the tyrosinase enzyme and melanin is transferred from melanocyte up to keratinocyteagainâ€¦ and againâ€¦ and again. and again, This causes dark clusters of color to appearnear the site of infection or injury. When it comes to PIH there are two different types. Epidermal PIH occursthe upper layers (epidermis)of skin and appear as welldefined light or dark brown patches. Dermal PIH, on the otherhand, occurslower layers (dermis) of skin
and appear as hazy bluegrey or purple patches. Dermal PIH happens when inflammation gets soo bad, melanin granules get shoved into the dermis where they don't belong. Aww Fuduckers!Now the epidermis constantly renews itself, but the dermis does not, so foreign bodieslike melanin get trapped inside and overstay their welcome. In this way, Dermal PIH is similarto a tattoo, and at times, can be just as difficultto remove! Now that you know a bit more about what causesPIH, we are going to look at treatments options and products to help you resolve it. So don't be a chicken!
