PIH and PIE: Difference and Solution for Both

Do you know the difference between PIH and PIE? If not, don't worry! This blog post will discuss the difference between PIH and PIE and how to treat them. Both of these conditions can be treated with the right products!

Let's get started.

An Overview of PIH

Post-inflammatory hyperpigmentation (PIH) is the darkening of the skin that occurs after an injury to the skin. It can happen after acne, a burn, or even something as minor as picking at a pimple. Darkening occurs when there's inflammation in the skin and melanocytes (the cells that give our skin its color) are stimulated to produce more pigment.

The good news is that PIH is not permanent and will eventually fade on its own. However, it can take months or even years for the pigmentation to disappear completely. And in some cases, PIH can lead to permanent scarring.

An Overview of PIE

Post-inflammatory erythema (PIE) is a condition that results in red or purple discolouration of the skin. It is commonly seen after injuries, such as burns, insect bites, and chemical peels. PIE can also occur after procedures like laser treatments and dermabrasion.

PIE is different from post-inflammatory hyperpigmentation (PIH), which results in brown or black skin discoloration. Both conditions are benign and usually resolve independently with time; however, treatments are available to speed up the healing process. Therefore, you must be careful when picking the right products for your skin.

Difference Between PIH and PIE

Here are the main differences between PIH and PIE:

  • PIE is often red or pink, while PIH can be any colour.
  • PIE can occur anywhere on your body but you will most likely get it on your face.
  • PIE will usually go away within a few weeks with no treatment.
  • PIH may last for months or even years ; if you don’t follow any treatmet.
  • The main difference between PIH and PIE is that PIE will go away on its own, while PIH will not.

How to Identify PIE and PIH Marks?

Different causes of PIE or PIH can help you know what kind of acne marks you have.

Causes of PIE

1. Skin Related Trauma

PIE can be caused by any sort of skin trauma, including but not limited to:

  • Abrasions
  • Burns
  • Cuts
  • Insect bites
  • Rashes
  • Surgery

2. Popping Pimples

While touching your face or picking at pimples may feel satisfying, it can worsen your skin condition. Popping pimples can cause the bacteria to spread, which might lead to PIE.

3 . Over Exfoliation

Over-exfoliation is another major cause of PIE. When you over-exfoliate, you are essentially causing trauma to the skin. This trauma can manifest in the form of micro-tears, which then leads to inflammation.

4 . Dry Patches

Dehydrated skin appears dry, rough and flaky. It can feel tight, especially after cleansing. Your skin may lack moisture due to external factors such as cold weather, indoor, indoor heating, or internal factors that can lead to PIE.

Causes of PIH

1. Sun Exposure

One of the most common causes of post inflammatory hyperpigmentation is sun damage. When the skin is exposed to UV rays, it can result in inflammation and ultimately lead to PIH.

2. Ageing

As we age, our skin becomes thinner and less able to repair itself as quickly. This can lead to post-inflammatory hyperpigmentation after even minor injuries to the skin.

3. Heavy Skin Treatments

Post-inflammatory hyperpigmentation (PIH) can cause heavy skin treatment. If you overuse the exfoliants, harsh acids, physical scrubs, and retinoids, it can lead to inflammation and damage your skin. This can result in PIH.

Post Inflammatory Erythema Treatment Products

For treating PIE, it is essential to use products that contain ingredients that will help to soothe the skin and promote healing. Some of these ingredients to look for in post-inflammatory erythema treatment products include:

Vitamin C: Vitamin C is a potent antioxidant that can help reduce inflammation and heal your skin.

Niacinamide: Niacinamide is another ingredient that is effective in treating PIE. It helps to reduce inflammation and redness and also helps to lighten dark spots.

Hyaluronic Acid: Hyaluronic acid is a substance that occurs naturally in the skin. It will hydrate and plump your skin, resulting in reduced scars on your face.

Kojic Acid:Kojic acid is a natural ingredient derived from mushrooms. It works by inhibiting the production of melanin, the pigment that gives skin its color.
