Pollution and long UVA rays: the main causes of pigmentation disorders

Resources\Visuels\V4\Headers\Articles\INT\v_header_3questions_default.jpg

Atmospheric pollution and long UVA rays mean the skin constantly suffers from external stress,
which leads to an uneven complexion. Irregularities appear, such as spots and a dull or greyish complexion.
A dermatologist explains.

1 - What is oxidative stress?

Oxidative stress is the source of pigmentation disorders

Oxidative stress is generated by a noxious synergy of pollution and long UVA rays. Pollution and long UVA rays are harmful as they produce free radicals able to penetrate the skin, thereby fostering the appearance of pigmentation disorders (spots and a dull and greyish complexion).

2 - What are the symptoms of pigmentation disorders due to oxidative stress?

There are two major symptoms: the appearance of spots and a greyish complexion

Oxidative stress leads to the disruption of melanocytes and their environment, called the melanotope, thereby triggering the process that leads to the appearance of spots and a dull complexion. On the skin surface, the oxidation of melanin, which is already present in the upper layers of the epidermis, leads to a greyish complexion.

Melanocytes are melanin-producing cells located in the lower part of the epidermis.
The melanotope is the environment surrounding the melanocyte (epidermis and dermis). Recent studies have confirmed its role, in the same way as the melanocyte, in the formation, persistence and reappearance of pigmentation disorders.
