Why do pigmented lesions occur?
Melanin is the natural pigment that gives your skin its colour. The amount of melanin in the skin determines whether you have a light or dark complexion. Pigmentation spots are darker because melanin is much more concentrated in them. This is often due to overexposure to the sun, resulting in UV damage to the skin. The root cause of post inflammatory hyperpigmentation (PiH) is increased melanin production, and in this case, the increase in melanin is triggered by the way skin heals after inflammation or injury. This inflammation triggers melanocytes – the melanin-producing cells – to release excessive melanosomes (pigment granules). The excessive pigment granules darken and discolor the formerly wounded area, remaining there long after the initial wound has recovered. PIH often affects people with acne. The more inflammation there is, the more obvious the area of discoloration will be both in terms of size and color. And, in cases where PiH is caused by acne, picking pimples can worsen the condition. Whilst not the cause of PIH, the sun can aggravate symptoms.
The laser treatment (Nd: YAG) of pigmented lesions consists of cracking open the pigment cells by the effect of the heat of the laser. At Skinline Clinic, we use either Lutronic’s Picoplus or their Clarity II. In this way, the discolouration is gradually removed. After the treatment, the stain will darken and even blacken and then gradually loosen over the days. Alternatively, photo rejuvenation using pulsed light (IPL) is also used to make these spots fade or disappear while the skin tone becomes more harmonious. The Etherea MX platform from Vydence Medical is our favourite or the Solari from Lutronic. The choice or combination of these two technologies varies from case to case and depends on the depth of the necessary treatment. The treatments generally require 2 to 4 sessions of 30 to 60 minutes.
Secondly, other technologies, such as dermabrasion or hydrodermabrasion, can be used to further improve aesthetic results.
