The viralization of health advice on social networks that contradicts expert recommendations is generating increasing concern among dermatologists, especially due to the recent anti-sunscreen trend on Tik Tok.
This current, which is amplified and becomes dangerous, is driven by influencers and entertainment figures with thousands of followers who promote the idea that the use of sunscreen is more harmful than beneficial, which could increase cases of skin cancer, as experts warn. The main argument of pro sol – among several – is that sunscreens contain aggressive chemicals that the skin absorbs.
Consulted by Infobae, Fernando Felice, plastic surgeon and professor at the University of Buenos Aires (UBA), expressed his concern about this trend: “Sunscreens are essential to prevent melanoma, a type of skin cancer that claims lives. daily around the world. We have to be clear, no one dies from using sunscreen every day,” said Felice to counteract misinformation.
Of course, sunlight not only improves our mood and reduces stress, but it also plays a crucial role in the synthesis of vitamin D that the skin and body need to be healthy.
However, exposure without sun protection is still a leading cause of skin cancer, and people should not be confused into thinking that not using sun protection will improve their vitamin D intake.
“Using sunscreen is essential to take care of your skin all year round, spring and the arrival of summer mark the right time to be more aware, since the hours of light and sunny days will increase and people will spend more time outdoors free,” the dermatologist from the Argentine Society of Dermatology (SAD), Christian Sánchez Saizar (MN 97,895), explained to Infobae.
“In these months we have to be more attentive to our skin care routine and not forget the last – and most important – thing, which is the use of sunscreen,” he added.
Along the same lines, international experts such as Dr. Steven Q. Wang, director of dermatological oncology and dermatology at Hoag Memorial Hospital Presbyterian in Newport Beach, California, acknowledged that experts must be clearer about this idea: many people are Avoid using sunscreen for fear of not getting vitamin D. And clearly this is not the case.
How to apply the protector
Surgeon Felice recommends applying sunscreen five minutes after a moisturizing cream, using a sun protection factor (SPF) greater than 50 on the face and avoiding sun exposure between 10 in the morning and 4 in the afternoon. .
It also suggests annual dermatological consultations starting at age 30 to detect possible premalignant lesions.
There are several myths about the use of sunscreen that Dr. Felice is in charge of debunking. For example, the belief that people with dark skin do not need sun protection is false, since this skin is also susceptible to sun damage.
Additionally, no sunscreen is completely waterproof, so you need to reapply it after swimming. Another myth is that makeup with SPF is enough to protect the skin, which is not true as it does not cover all exposed areas.
Dermatologists insist that using sunscreen is crucial to preventing DNA damage in skin cells, which can lead to the development of cancer.
Keys to protect the skin from the sun
The use of sunscreens must be applied properly to ensure effective protection against UVA and UVB rays, which are responsible for problems such as premature aging and skin cancer. Dermatologist Lilian Demarchi (MN 88.365) emphasizes the importance of blocking UVA rays daily, present throughout the year, to maintain healthy skin.
Sunscreens fall into two main categories: chemical ones, which absorb ultraviolet light, and physical ones, which act as a shield that reflects the light. Sánchez Saizar highlighted that hybrid products, which combine both types, offer very effective broad-spectrum coverage. It is crucial to apply sunscreen at least 15 minutes before sun exposure and renew it every two hours, especially if you are in contact with water.
Each skin type requires specific care, but they all need broad-spectrum protection and a high sun protection factor (SPF). Sensitive skin, for example, should take extreme precautions to avoid redness or rosacea. In addition, it is important not to skimp on the amount of product applied, covering the face, neck and body well if you are going to be exposed to the sun.
Using low FPS is not recommended. Sánchez Saizar suggests always opting for SPF 50, as it offers 95% protection against UV rays, compared to the 93% provided by SPF 30.
This difference, although it may seem minor, accumulates over time and can make a big difference in the health of your skin.
In addition to applying sunscreen, it is recommended to avoid sun exposure during the hours of greatest radiation, between 11 in the morning and 4 in the afternoon. Seeking shade and using physical barriers such as hats and dark glasses are additional measures that can help protect the skin.
summer treatments
In the summer months, beauty treatments experience an increase in demand, but not all of them are recommended. Alfredo Romero, a doctor specializing in plastic and reconstructive surgery (MN 105550), explained to Infobae that “laser and pulsed light procedures should be avoided, as they can weaken and sensitize the skin, increasing the risk of hyperpigmentation due to sun exposure.”
Dr. Romero emphasized the importance of following natural measures for skin care, such as adequate hydration, a healthy diet, and the use of sun protection. These habits are essential to keep the skin in good condition, regardless of the aesthetic treatment chosen.
Pablo López Bergami, researcher at CONICET and the Center for Biomedical, Basic, Applied and Development Studies (CEBBAD) at Maimónides University, warned about the dangers of excessive exposure to ultraviolet (UV) radiation during the summer. According to López Bergami, UV radiation can cause damage to the DNA of skin cells, which could lead to malignant transformations, such as melanoma, the most aggressive type of skin cancer.
Melanocytes, cells located in the epidermis, are responsible for protecting the body from UV radiation through the production of melanin, a pigment that absorbs and disperses solar radiation. However, this protection capacity is not unlimited. Genetic factors and prolonged sun exposure can cause damage to the DNA of melanocytes, which could eventually trigger the development of melanoma, which clinically manifests as a mole or a pigmented lesion with specific characteristics.
During the summer months, the intensity of UV radiation increases considerably, making it necessary to take extreme precautions to avoid overexposure to the sun. López Bergami emphasizes the importance of protecting the skin to prevent injuries that could have serious long-term consequences.
Melanoma is a growing concern due to its aggressiveness and potential for metastasis. Early detection and adequate protection against UV radiation are essential to reduce the risk of developing this type of skin cancer.
López Bergami urges the population to take preventive measures, such as the use of sunscreen, appropriate clothing and avoiding sun exposure during the hours of greatest intensity.
