Post-inflammatory hyperpigmentation, also called PIH, is a dark discoloration of the skin caused by inflammation or damage to the skin. The dark pigmentation usually takes the shape and size of the damage that was there before. The color of the scars depends on the skin type.
Post-inflammatory hyperpigmentation is common, especially in dark skin tones. The discoloration is harmless and in some cases disappears on its own. In a few cases the discoloration can be permanent and this is experienced as very disturbing.
Lentigo solaris (age spot)
The sun is wonderful and important for humans. Sunlight and solar heat delivered to the skin play a role in our well-being, mood and in the production of Vitamin D in our body. A lentigo solaris or sun spot is a benign pigmentation spot that develops on skin that comes into frequent contact with the sun. Usually lentigo solaris does not appear until older age. That is why it is also called age spot (lentigo senilis). Solaris lentigo occurs in 90% of all white people over the age of 60. It occurs only exceptionally in people with a dark skin type. A café-au-lait stain literally means ‘coffee with milk stain’, a name due to the even coffee color of the stain. It is a common benign mole, which is already visible during birth or arises after a few weeks or months after birth. Usually it is one spot, without pigment spots around it and has a round or oval shape with a sharp boundary. About 10% to 20% of the population has a café-au-lait stain.
Melasma is hyperpigmentation in the face that causes brown spots. It usually occurs in women, but can also occur in men who, in their younger years, have excessively exposed their skin to sunlight without proper protection. Melasma often occurs during the woman’s fertile period and especially during pregnancy. Melasma can come on suddenly and worsen over a longer period of time, or it can go away on its own. Unfortunately, this is not always the case, sometimes the pigmentation remains for a longer period of time. Fortunately, there are options to reduce melasma and bring the skin back under control.
With the PicoWay we can target the pigmentation in both the superficial and the deeper layers of the skin. By means of the special setting, the laser beams penetrate the skin without damaging the epidermis. The result of this is a lighter/more even skin and an improved skin structure.
The biggest challenge in recent years has been treating deep pigment and melasma in dark-skinned people. Previously, this was rarely possible or only possible with bleaching agents or limited peels. But now thanks to the Picoway laser, this problem is no longer the case! Because the Picoway works photoacoustic, pigment can be removed without unnecessary heat and inflammatory reaction. Due to this technology development, the Picoway is currently the best choice for dark and tinted skin with the least possible risk of scarring and/or hypo-/hyperpigmentation.
