Sun and brown spots
Harmless, certainly, but nevertheless unsightly, so-called sunspots are the direct consequence of a disruption in the production and distribution of melanin on the surface of the epidermis. In the question: UV rays, the inflammatory process of which excites the activity of tyrosinase, an enzyme that allows melanocytes to produce melanin, which causes skin pigmentation. Activated by UV, tyrosinase can therefore get carried away and produce too much melanin: brown spots appear and multiply, and the complexion gradually loses in uniformity.
Acne and sun don’t mix. First, UV exposure eliminates pimples because the rays reduce inflammation, limit bacterial growth and thicken the skin. But the rebound effect is formidable: not only the sebaceous glands – in charge of sebum production – work accelerated, but also the skin cells harden on the surface of the skin. The sebum then accumulates in the pores, which become blocked, leading to the formation of blemishes. These unsightly pimples also damage the skin tissue. Once gone, they can leave residual marks in the form of hyperpigmented flat spots: this is called post-inflammatory hyperpigmentation.
The skins of pregnant women
During pregnancy, an anarchic cluster of brown spots can form on different areas of the face: on the forehead, cheekbones, and even the top of the lips. The responsible? Hormones are naturally produced by the body that over-stimulate melanocytes, the cells in charge of melanin production. This hormonal imbalance, often genetic in nature, is called a “pregnancy mask” or even melasma, chloasm, or chloasma. It is activated – or worsened – mainly through exposure to UV rays.
To avoid it in summer, it is, therefore, necessary to limit exposure to the sun as much as possible during the hottest hours and to wear covering hats and clothing. Applying for UV protection SPF50 care daily, every two hours, and even in town is also necessary. In winter, more moderate protection can be quite suitable, with an SPF30 for example, if the sunshine is weak. To be used in addition: daily protections, such as Eucerin ANTI-PIGMENT treatments which form a barrier against UV rays, reduce hyperpigmentation, and prevent the formation of pigment spots.
Also be careful not to let your guard down in the months following childbirth since this hormonal impregnation can last up to six months after birth.
In general, dark skin, mixed-race and black skin are more affected by hyperpigmentation spots insofar as their pigmentation is stronger than that of fair skin. The marks, more delicate to remove, remain more visible, and longer. It is therefore essential for them to apply sun care in the event of exposure.
How to remove stains?
In the event of the appearance of pigment spots, two options are possible to reduce them.
The first, more invasive: opt for solutions in the office with a dermatologist, to eliminate dead cells and stimulate the growth of new ones. The doctor recommends either a chemical peel, based on AHA, or laser therapy. The latter acts on the superficial or deeper layers of the skin, via high-energy light.
Second option, softer and better suited to all those looking for less abrasive solutions: dermo-cosmetic care. Among them, the four treatments in the Eucerin ANTI-PIGMENT range treat not only extensive spots but also the most localized ones. At the heart of the Duo Serum, SPF30 Day Care, Night Care, and Dark Spot Corrector formulas, a unique active ingredient: Thiamidol. This patented ingredient * took 10 years of research and works at the source of hyperpigmentation, by proven reducing the production of melanin. After two weeks of regular use, the first results are visible: dark spots are reduced ** and the complexion is brighter and more radiant. The spots then continue to fade if you continue to apply.
In addition, the ANTI-PIGMENT day cream formula also contains an SPF30 to protect the skin from UV rays and help prevent the reappearance of dark spots.
* Thiamidol patented in France, Belgium, the Netherlands. ** Clinical evaluation carried out over 12 weeks on 34 volunteers, joint application of Eucerin® ANTI-PIGMENT Serum Duo and Day Care SPF30 twice a day for 12 weeks.
