Solar lentigines or sunspots


What are solar lentigines?

Lentigo is the hyperpigmentation of the skin that is created as a result of the increase in melanocytes. These skin cells are responsible for processing melanin and providing skin pigmentation, when this process is accelerated, spots with delimited contours are produced that can be mistaken for freckles.

Nowadays it is common to find patients concerned about these skin marks, below we will share all the details about lentigines so that you have the necessary information to combat them.

Types of lentigines

Solar or senile lentigines:

They are characterized by being a benign lesion on the skin, however they demonstrate the aging of the skin since it is related to skin degeneration due to radiation.

As it is a solar effect, they tend to appear more frequently in areas that receive direct sunlight such as the hands, décolleté and face. They develop in the patient’s adult stage.

Simple Lyngigo:

This type of mark is easily confused with moles since they are small spots that appear from childhood, as it is a skin lesion that is not related to the sun they can appear in any area of the body. It is also considered benign.

Malignant Lyntigo:

It is a melanoma skin tumor, although it is the least aggressive presentation of this type of cancer and requires immediate specialized care.

The worst thing about this type of lentigo is its complexity to make the diagnosis, since it resembles other benign lesions, so experienced medical attention is required to evaluate it.

Symptoms of senile or solar letingos.

These injuries often occur without warning in older people. They appear as a result of photoexposure to the sun and do not present symptoms beyond visual changes in the skin.

What you notice are small, flat, rounded marks that can be mistaken for freckles.

Causes of lentigines or sunspots.

The main cause of the production of solar lentigines is prolonged exposure to the sun, they are produced by the accumulation of ultraviolet light in the dermis that, throughout life, activates the multiplication of melanocytes.

To understand it better, we can say that melanocytes are cells present in the skin that are responsible for producing pigments (melanin), when UV rays influence these cells, they can stimulate an accelerated production of this substance, staining the skin with another tone in localized areas.

As they occur as a consequence of exposure to the sun throughout life, they are now recognized as age spots and their treatment is focused on an aesthetic sense.
