Pigmentation caused by wounds

Pigmentation caused by wounds

After wounds or inflammations of, for example, acne, red to brown discolouration may remain. We also call this post-inflammatory hyperpigmentation (PIH). We often see this with tinted to dark skin after acne. These spots generally don’t hurt and don’t itch.

If the pigment is superficial, the color is often light to dark brown. When the pigment is a bit deeper, it can have blue-gray discoloration. The pigment spots can become darker due to the sun.

The treatment of PIH at Huid & Laser Utrecht

At Huid & Laser Utrecht, post-inflammatory hyperpigmentation can be treated with the lasers below. The choice of treatment depends on the color of the spots and the skin color. During the consultation, we assess the skin and make a customized treatment plan. The choice of treatment depends on your wishes and the color of the spots and the skin color. Sometimes a combination of several lasers gives the best result.

Fractional Erbium-YAG laser (2940 nm)

This laser is recommended for spots that are dark to blue-gray in color. The fractional Erbium-YAG (2940 nm) creates many tiny holes in the skin, through which the pigment cells are, as it were, pierced and re-ordered. The excess pigment is destroyed and removed.

The advantage of this laser treatment is that the structure of the skin is also refined and relief differences in the skin (such as scars) are reduced.

Fractional Erbium-Glass laser (1540 nm)

The Fractional Erbium-Glass laser is recommended when there are scars visible as red spots and general skin improvement is desired.

The light from the laser is absorbed by water in the skin. The energy is converted into heat and provides controlled tiny holes in the skin through evaporation. These holes are replaced by new collagen fibers, which improves the skin’s texture and fades superficial scars (red spots). The skin also starts to build new fine blood vessels, which improves blood flow and reduces dilated blood vessels, visible as red spots.

IPL (Intense Pulsed Light)

IPL is often used for red spots in the skin that are left behind after a wound or inflammation. The light pulses are absorbed into the skin by the red color of the superficial vessels, which converts the energy into heat. This heat coagulates the kegs, causing them to break and to be cleaned up by the body.

Pigment laser Alexandrite (755 nm)

When the pigmentation spots are light brown in color and are superficial in the skin, they can also be treated with the pigment laser. The light from the pigment laser is absorbed by the dark color in the pigment cells. The energy is converted into heat and ensures that the excess pigment is destroyed.

With this laser treatment, only the pigment spot is treated locally. Since we often see that post-inflammatory hyperpigmentation has developed after acne inflammation, overall skin improvement is desired. If this is the case, preference is given to treatment with the fractional laser.
