Post Inflammatory Hyperpigmentation (PIH) : Pt I – What Causes Dark Spots On Skin


PIH TEXT Today Bertie and I are going to talk to you
about PIH or Post Inflammatory Hyperpigmentation. Oh, Thanks Bertie! And like the spots on this
egg, 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 over-reacts to trauma in the skin. Conditions like acne,
eczema, psoriasis, and even little things like insect bites (ow!) trigger an inflammatory
response that can cause melanin production go bonkers. Since melanin is the brown pigment
that gives our skin its color, the result is dark marks and uneven skin tone. Now normally our skin looks a little more
like this. Melanin’s job is to give you an even skin tone and protect you from UV
radiation. To that, melanin says, “You’reWelcome America”. Turn up the sun exposure and skin turns up
tyrosinase, 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 lounging in the sun, your skin is hard at work! Sometimes the body’s immune system destroys
the melanocytes, the cells that make the melanin. This condition is called vitiligo, and the
result 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 world
that uneven skin, light or dark can still be beautiful. In skin affected by PIH, inflammation from
everyday conditions like acne can cause melanin production to go haywire! The immune system
triggers the tyrosinase enzyme and melanin is transferred from melanocyte up to keratinocyte
again… and again… and again.. and again, This causes dark clusters of color to appear
near the site of infection or injury. When it comes to PIH there are two different types. Epidermal PIH occurs in the upper layers (epidermis)
of skin and appear as well-defined light or dark brown patches. Dermal PIH, on the other
hand, occurs in lower layers (dermis) of skin and appear as hazy blue-grey or purple patches. Dermal PIH happens when inflammation gets soo bad, melanin granules get shoved into the dermis where they don’t belong. Aww Fuddruckers!
Now the epidermis constantly renews itself, but the dermis does not, so foreign bodies
like melanin get trapped inside and overstay their welcome. In this way, Dermal PIH is similar
to a tattoo, and at times, can be just as difficult
to remove! Now that you know a bit more about what causes
PIH, we are going to look at treatments options and products to help you resolve it. So don’t be a chicken! Subscribe to this channel and check out part two of our PIH series. Feeling peckish for more? Then join the flock at Msbeautyphile.com.
