Don’t we all feel disgruntled when we wake up with spots when the night before, our skin looked so smooth and spotless? Not only are the zits annoying, when they grow and turn red, they often leave behind dark spots. These dark marks are called post-inflammatory hyperpigmentation (PHI) and are often as dispiriting and vexing as the pimples themselves.

Depending on the skin tone and the depth of the discolouration, this post-inflammatory hyperpigmentation can range in color from pink to red, purple, brown, or black. They can appear on all skin types but for people with darker skin tones, they are frequently longer-lasting and have a deeper colour. Since PIH is “just” skin pigmentation and doesn’t damage the follicle, collagen, or elastin, they are flat or smooth and thus are not called acne scars.

You can tell if you have acne scars or marks when you run your fingers over the area with acne. If the skin feels smooth without any textural changes like pits and bumps, then you’re having acne marks.

What Causes Post-Inflammatory Hyperpigmentation?

When our skin gets a wound, zit, or any other skin trauma or irritation arises, such as a rash, even an insect bite, the area around the irritation can become inflamed. The more inflamed the area is, the redder it will appear.

Picking, squeezing, scratching, or just too much handling of the skin leads to a skin response that will extend the inflammation period. And making things worse, this will also put dust, oil, dirt, even bacteria on your skin. All of which will make your skin even redder. This redness comes from an increase in the local blood flow, it’s the immune system response by letting white blood cells into the area to fight the infection.

Even when the skin heals, the redness can remain and we’ve our new pimple mark. The PIH can last up to 6 months and it’s a sign that the skin is trying to repair itself after the inflammation. How long the redness lasts depends on several factors. These can be your skin tone, your skin type, your genetic makeup, your skincare, the size and depth of the inflammation of the zit, and how much you touched it.

In the aftermath, after one or two months, the redness subsides. Since white blood cells were called into the areas an immune response to fight bacteria and clear of debris, the surrounding area was in stress mode. In this stage, melanin is released as a byproduct of stressed cells. This is melanin – or pigment – leaves a visibly darker mark than the surrounding skin even after the zit has cleared.

Piling on concealer to cover up zits or the aftermath of them, dark spots are not the way to go. But since we now know how a red mark appears when our skin gets inflamed, the best way is prevention.

It will help keep your skin healthy and is key to fading discolouration.
