They splashed our skin in a capricious way and their presence says much more than it seems to the naked eye because behind the aesthetic 'discomfort' a health problem can be hidden.
Why do stains come out?"Some are present in the skin from birth and are genetically determined.They are the cases of some moles (congenital melanocytic nevus) and those known as 'coffee spots with milk'.However, most of those that appear on the skin are later a consequence of age and sun exposure, "says Ignacio Sánchez Carpintero, a doctor of International Dermatological Clinic (Madrid).
Your diagnosis is not always simple."A mole can be confused with a solar lent or a seborrheic keratosis.Sometimes, it can be complex to distinguish a benign mole from an incipient melanoma, a malignant tumor that can be very aggressive ".
Calibrating its nature is essential before deciding a treatment."The dermatologist is the specialist who best knows this pathology and the one who can make best decisions when treating them.Spots are not always an aesthetic issue and should be evaluated by an expert in the field, "says Sánchez Carpintero.
Face and hands
The fact that they usually sprout in very specific areas is not accidental."The body parts that are most exposed to the sun are the face and back of the hands.Therefore, it is there where sunny spots known as lentigos appear more frequently.On the face we also see a type of hormonal cause known as melasma and that are frequent in women of fertile age ".
Can we avoid your appearance?"No, we cannot completely avoid its appearance but, with the constant use from an early age of photoprotectors and adequate clothing, we can get less to appear".
Once present in the skin "they can be treated with products with depigmenting action".These compounds, the doctor continues, are composed "with active ingredients such as hydroquinone, kojic acid and retinoic acid, which manage to mitigate them in some cases".
In clinical practice, solar lentigos are treated with "a specific laser generically known as Q-Switched laser".One of them is "Alejandrita's Laser of Short Pulse" (different from that used in hair removal).According to Sánchez Carpintero, the solar lentigos "respond very well to this treatment".
Once these lesions have been resolved, the improvement can be maintained "with some of the compounds mentioned above, insisting a lot on the importance of avoiding the sun and using in those high index photoprotective areas".
En el caso del melasma, lo más indicado es utilizar un tratamiento, "conocido como Clear melasma, que combina un láser de baja potencia (Clear & Brilliant) junto con la aplicación de productos despigmentantes".
The bad news is that, despite avoiding the sun and using solar filters, it can happen that spots reappear."The reappearance time will depend on the type of spot, the characteristics of the skin and personal care, especially in relation to sun exposure," he concludes.
