Sun exposure is the primary cause of skin pigmentation spots, as UV rays trigger the production of melanin that causes uneven pigmentation. Melanin, the brown pigment that determines the colour of your skin, is the body’s defence against damaging UV rays. The body releases more melanin to protect the skin when overexposed to UV rays. This rise in melanin levels is what causes a tan. So sun spots – also called age or liver spots – are caused by overexposure to the sun. Freckles are also a very common form of sun pigmentation. In some cases, the sun can also cause melanin (the skin pigment) to break down unevenly, i.e. darker patches where its accumulation is greater. In this case, discoloration may occur not only on the face, but also on the neckline or arms.
Exposure to UV rays also accelerates aging due to the way in which it interrupts complex cellular structures, causing the skin to lose its firmness and elasticity.
The skin of the face is thinner and more delicate than the skin of the body – so the cells are more easily damaged. When they are damaged by exposure to the sun, they’ll often release more melanin. This leads to the formation of discoloration on the face after sunbathing. They are small and circular in shape. Remember, your face is exposed to the sun every day – not only in summer and not only on the beach. Even if you are not sunbathing, try to use a face cream with SPF – like Cellular Luminous630 anti dark-spot day moisturiser SPF50
– to protect yourself against the harmful effects of UV radiation and the formation of discoloration.
Also, don’t forget the skin on the rest of your body which may react in a similar way. In the sun, always make sure you’re using a sun lotion suited to your skin type.
