Dermatologist Dr. Giovanna Ciocca recommends applying sunscreen five times a day to prevent skin cancer and protect the skin from spots [1].

Consistent sun protection is critical because ultraviolet radiation can lead to malignant growths and permanent skin damage. Regular application ensures that the protective barrier remains effective throughout the day, regardless of activity level.

Dr. Ciocca said the frequency of application is a key factor in reducing the risk of developing skin cancer [2]. While many people apply sunscreen only once in the morning, the effectiveness of the product degrades over time due to sweat, friction, and exposure to light.

The need for rigorous prevention is highlighted by the scale of the issue in the U.S. More than six million people are treated for skin cancer each year [3]. This high volume of cases underscores the importance of preventative measures as a primary defense against the disease.

Medical professionals emphasize that protection is necessary even during winter months. Radiation remains present throughout the year, meaning that seasonal changes do not eliminate the need for daily sunscreen use [4].

Public health awareness efforts often peak around specific dates, such as World Cancer Day on Feb. 4 [5]. However, clinicians said that daily habits are more effective than intermittent awareness campaigns for long-term health outcomes.

The recommendation for five daily applications reflects a shift toward treating sunscreen as a continuous maintenance habit rather than a one-time morning application. By addressing the degradation of UV filters throughout the day, this approach aims to lower the incidence of skin cancer in a population where millions already require treatment annually.
