Melasma is a condition that is characterized by the appearance of dark spots on the skin, most commonly on the face, but it can also occur extra-facial, with involvement of the arms, neck and neck. It affects women more often and can also be seen in men. There is no definite cause, but this condition is often related to the use of female contraceptives, pregnancy and, mainly, sun exposure. The triggering factor is exposure to ultraviolet light and even visible light. In addition to hormonal factors and exposure to sunlight, genetic predisposition also influences the appearance of this condition.
Epidermal Melasma: When there is an increased deposit of pigment through the epidermis (the most superficial layer of the skin).
Dermal Melasma: Characterized by the deposition of melanin around the superficial and deep vessels.
Mixed: When there is excess pigment in the epidermis in certain areas and in the dermis in other regions.
There are still three common types of facial pattern of melasma, the malar (cheekbones), centrofacial (forehead, cheeks, above the lip, nose and chin) and mandibular, depending on the region in which it appears.
Dark or brownish spots start to appear on the face, mainly on the cheekbones, forehead, nose and upper lip (the so-called fluff). Extrafacial melasma can also occur, with the appearance of dark spots on the arms, neck and neck. The spots have irregular and well-defined shapes, being generally symmetrical (equal on both sides). Often, people with melasma can aggravate the condition with an inappropriate treatment or procedure, with significant worsening of the spots.
To help remove stains, whitening creams based on hydroquinone, glycolic acid, retinoic acid, azelaic acid, among other substances can be used, and the results take about two months to appear. The method does not work on all patients, and even if the results appear more quickly, it takes time to stabilize the condition and prevent minimal exposure to the sun from bringing symptoms back. Treatment will be constant / continuous. The treatment of melasma can be done with Renascer Skin and ChelatoDerme..
