The Nizhny Novgorod oncologist answered the most common questions about tanning.

      July 16, 2026 07:00 Society The equator of summer is another reason to remember skin protection from the sun. Oncologist-dermatologist Natalia Sivodedova from the Nizhny Novgorod Regional Oncology Dispensary answered the most common questions from patients and explained which myths about tanning can be dangerous.

      Is it true that a tan is a sign of health?

      No.

      As the doctor explains, a tan is a protective reaction of the skin to damage from ultraviolet rays. Under the influence of UV rays, the DNA of cells is damaged, and the body begins to produce melanin, which gives the skin a darker shade.

      According to the specialist, the stronger the tan, the more such damage the skin has accumulated.

      If there was no sunburn, does that mean there is no danger?

      Not at all.

      Natalia Sivodedova notes that danger comes not only from severe burns. In medicine, there is a concept of cumulative UV dose — it is the sum of all episodes of sun exposure. Even half an hour without sunscreen during a walk, trip, or shopping accumulates over time.

      It is this accumulated exposure to ultraviolet light that can lead to photoaging of the skin, and in some cases, to malignant changes in cells.

      Is sunscreen only needed at the beach?

      No.

      As the doctor explains, UVA rays affect the skin year-round. They pass through clouds and even window glass, so it is recommended to use SPF products daily, not just during water activities.

      Is it enough to apply SPF once in the morning?

      No.

      Most sunscreens remain effective for about two hours. If a person is outdoors, the cream needs to be reapplied every two hours, as well as after swimming or towel drying.

      Who should especially pay attention to their skin condition?

      The doctor recommends paying increased attention to health for:

      - people with fair skin, red or light hair, blue or green eyes;

      - those who had sunburns in childhood;

      - people with a family history of melanoma or other types of skin cancer.

      For these categories, regular check-ups with a dermatologist are a necessity, not just a recommendation.

      How to reduce the risk of skin cancer?

      Doctors advise following simple preventive measures:

      - use sunscreen with SPF 50 daily, even in cloudy weather;

      - apply the product 15-20 minutes before going outside;

      - avoid direct sunlight from 11:00 AM to 4:00 PM whenever possible;

      - wear a hat, sunglasses, and closed clothing made of dense fabric;

      - self-examine the skin once a month, and undergo professional dermatoscopy once a year.
