Hospiten warns: Excessive sun exposure can take a toll on skin health

Hospiten reminds us of the importance of taking care of our skin, especially in the summer, when it is exposed to high temperatures; therefore, it is necessary to step up preventive measures by protecting the skin through various methods.

Dr. Nuria Pérez Robayna, a dermatologist at Hospiten Rambla University Hospital, points out that it is essential to perform regular self-exams of the skin to detect any new lesions or moles that may show warning signs.

Among the main indicators to watch for are those known as the “ABCDE” signs: asymmetry, irregular borders, changes or variations in color, a diameter greater than five or six millimeters, and changes in the lesion over time. In addition, the dermatologist highlights other signs such as inflammation, frequent bleeding, an increase in size, or rapid growth.

The specialist also reminds us of the importance of the so-called “ugly duckling sign,” which refers to moles or lesions that stand out because they are different from the rest on the skin and, for that reason, should be evaluated by a specialist.

Prevention: Key to Combating Melanoma and Other Skin Cancers

Melanoma is the type of skin cancer with the worst prognosis, so early detection is essential. However, there are other skin lesions that also require attention, such as actinic keratoses or basal cell carcinoma, which can manifest, for example, as wounds that do not heal completely or lesions resembling persistent, recurring flaking.

“If we notice any change or lesion that seems abnormal or unusual, we should consult a specialist,” says Dr. Pérez Robayna. The expert states that in recent years there has been “an increase in diagnoses of skin cancer and melanoma, which could be related both to greater cumulative sun exposure over the course of a lifetime and to the aging of the population,” but that more and more cases are being diagnosed in the early stages thanks to greater public awareness and early consultation.

Year-Round Sun Protection

The dermatologist emphasizes that sun protection should be part of daily routine, especially in regions like the Canary Islands, where solar radiation is present year-round.

For this very reason, she recommends using adequate sunscreen daily, preferably with a high SPF, and to supplement it “with physical measures such as hats, sunglasses, T-shirts, or umbrellas, especially during outdoor activities”—a series of measures whose importance, she stresses, “must be conveyed from an early age,” she says.

The specialist states that children under six months of age should not be exposed to the sun and that sunburns during childhood and adolescence are linked to a higher risk of developing skin cancer in adulthood. Likewise, people with fair skin are more prone to sunburn and, as a result, face a higher risk of developing both melanoma and other types of skin cancer.

The doctor also notes that, although the sun contributes to vitamin D production, regular exposure during daily activities is usually sufficient for most people. “In the event of a vitamin D deficiency, it is preferable to take supplements prescribed by healthcare professionals rather than recommending excessive sun exposure, as this can increase the risks associated with ultraviolet radiation,” she states.

Ultraviolet radiation remains the main risk factor

Dr. Pérez Robayna reminds us that ultraviolet radiation—specifically UVB radiation—is the main factor linked to the development of skin cancer, as it can cause changes in the DNA of skin cells.

For this reason, she recommends applying sunscreen before leaving home, reapplying it approximately every two hours, and reapplying it after sweating, swimming at the beach, or in a pool.

The specialist adds regarding the regular use of screens that “prolonged exposure to blue light can contribute to the development of pigmentation disorders, such as melasma,” although she emphasizes that the primary risk factor for skin cancer remains ultraviolet radiation.
