Post-inflammatory erythema (PIE) and post-inflammatory hyperpigmentation (PIH) are two types of skin discoloration that can occur after an inflammatory skin condition. While they may appear similar at first glance, there are some distinct differences between the two.
Post-inflammatory erythema (PIE) is a type of skin discoloration that occurs as a result of blood vessel damage in the skin. It appears as red or pink patches on the skin and is often seen after inflammatory skin conditions such as acne, rosacea, or eczema. PIE occurs when the inflammatory response causes damage to the tiny blood vessels in the skin, leading to increased blood flow and resulting in a red or pink appearance.
Post-inflammatory hyperpigmentation (PIH) is a type of skin discoloration that occurs as a result of excess melanin production in the skin. It appears as dark brown or black patches on the skin and is also often seen after inflammatory skin conditions such as acne, eczema, or psoriasis. PIH occurs when the inflammatory response triggers the production of excess melanin in the skin, which leads to the formation of dark spots.
How Can You Tell Which Type You Have?
The easiest way to tell whether you have PIE or PIH is by looking at the color of the affected skin. PIE appears as red or pink patches on the skin, while PIH appears as dark brown or black patches. If you have recently had an inflammatory skin condition and notice discoloration, it is important to pay attention to the color of the affected skin and seek medical advice if you are unsure about the type of discoloration you have.
Treatment options for PIE and PIH differ depending on the type of discoloration. Here are some options:
