Dr. Vizcaíno, dermatologist: "These white spots usually appear over time and with chronic sun exposure."

The white spots that begin to appear on the skin , especially on the arms and legs , as the years go by, are not a phenomenon unfamiliar to dermatologists. This condition is called guttate hypomelanosis , and it is much more common among adults than it might seem.

According to Dr. Vizcaíno , a dermatology specialist, these are rounded, white skin lesions that arise from a combination of two factors: natural aging of the skin and chronic sun exposure . "These rounded, white spots usually appear over time and with chronic sun exposure," the expert noted.

These types of marks tend to appear on the most exposed areas of the body, such as the upper and lower limbs . Although they may be aesthetically striking or even bothersome, they pose no danger. However, they do have an indicative value: their appearance warns of accumulated sun damage to the skin.

"They are not dangerous, but once they appear, they do not usually disappear on their own."

What do these spots indicate?

The dermatologist emphasized that these lesions, once visible, don't tend to disappear on their own. "They're not dangerous, but once they appear, they don't usually disappear on their own," he clarified. In other words, their presence becomes a visible marker of the deterioration caused by ultraviolet radiation over time.

Microscopic analysis of these areas allows for a better understanding of the phenomenon. What is observed is a significant reduction in melanocytes , the cells responsible for producing pigment in the skin. "It's as if the melanocytes have been depleted from so much sun exposure," explained Dr. Vizcaíno , referring to the cellular deterioration caused by continuous solar radiation.

How can it be prevented?

The best way to prevent these spots from appearing, according to the specialist, is through adequate sun protection . "We have to focus on preventing them," he stated. To do so, he recommends resorting to both physical measures, such as wearing clothing that covers the skin, and sunscreen applied correctly and throughout the year.

This type of prevention not only helps keep your skin looking healthy, but also reduces the risks associated with photoaging and other more serious skin conditions. Ultimately, taking care of your skin means responding early to signs like these.

White spots shouldn't cause medical alarm, but they should be interpreted as a warning. Although they aren't dangerous in and of themselves, they represent the consequences of prolonged sun exposure without adequate protection. The body, through its skin, reveals the consequences of excessive solar radiation.

Protecting yourself isn't just a matter of aesthetics, but also of health. The experts' recommendation is clear: use sunscreen daily, even during the cooler months, and don't be complacent about the apparent lack of sun. After all, as the dermatologist concludes, the skin has a memory .
