Radiation emitted by the sun's rays is the main cause of melasma, which are dark spots on the skin, but frequent use of radiation-emitting objects such as cell phones and computers can also cause stains on the body.
Melasma usually appears on the face, but may also appear on the arms and on the neck, and it is necessary to use sunscreen daily to avoid this problem.
Causes of melasma
In addition to the sun's rays, melasma can be caused by the constant use of luminaires, computer, TV, cellular, iron, dryers and hair planks as the spots appear due to the heat emitted by these objects.
Melasma is more common in women, especially during pregnancy, but the use of birth control pills, face-lift creams, and a diet low in folic acid can also cause blemishes on the skin.
How to prevent stains on the face
To prevent melasma, sunscreen should be used daily on areas of the body that are exposed to light and heat, even at home or when working indoors. People who work outdoors and are exposed to the sun should remember to reapply the sunscreen every 2 hours.
In cases where work is done indoors, in addition to sunscreen, other tips are to take breaks throughout the day for coffee or toileting, and to reduce the clarity of the computer and cell phone screen, as the more light, the more heat produced and the greater the risk of spots on the skin.
Treatment for melasma
The diagnosis and treatment of melasma should be made by the dermatologist, and the techniques used to treat the problem depend on the type and severity of the stain.
Usually, the treatment is done through the use of whitening creams and chemical peeling or dermabrasion, which are procedures used to remove the dark layers of the skin. See how the treatment is done for each type of blemish on the skin.
