Post-inflammatory hyperpigmentation

Post-inflammatory hyperpigmentation

Post-inflammatory hyperpigmentation (PIH) is created after an inflammation in small parts of the skin, thus appearing in some places dark colored patches that stand out in relation to the shade of the rest of the skin. Skin inflammation can be caused by acne, a mosquito or other bug bite, injury, and other factors.Unless the inflamed areas happen to be symmetrical on both sides of the body. PIH spots are usually asymmetric.
PIH develops after the skin produces too much melanin, which is a natural skin pigment. Melanin production is activated when the skin regenerates, which it naturally does in response to inflammation.The good news is that there are ways to treat this condition and prevent it from getting worse. A treatment option includes skin lighteners, retinoid skin creams, and azelaic. Additionally, using sunscreen can prevent PIH spots from getting darker.


Mesopen is an alternative form of mesotherapy. It helps the penetration of active substances, creating portals of entry into the skin barrier with the creation of controlled micronulls, thanks to its specially designed head (pen with 12 tiny titanium pins), without obvious skin injury. Through this mechanism of action, the penetration capacity of the active substances increases.
