8 Consequences of not using sunscreen daily
Exposure to the sun and its UVA and UVB rays is inevitable for those who live in Brazil: almost all the extent of the country lies between Ecuador and the Tropic of Capricorn, and the predominant climate is tropical.
On the positive side, the sun strengthens the bones and joints and reduces the risk of depression, since it stimulates the production of serotonin in the brain.
risk of development of diseases such as skin cancer and cosmetic damage - photoaging and appearance of wrinkles, for example.
Here comes the sunscreen. "The correct use of sunscreen is an investment in the health and beauty of the skin," says Luciana de Abreu, a dermatologist. of the clinic Dr. André Braz (RJ). Dermatologist Giselle Sanches also agrees and adds: "Just as we have a habit of brushing our teeth several times throughout the day, we can get used to applying and reapplying the sunscreen daily."
And it's never too much to point out that this investment is not seasonal: it is not only summer that sun protection should be part of the daily routine of skin care. The use of sunscreen is essential throughout the year, no matter what the weather of the day.
The correct protection and risks of not following it
The Brazilian Consortium of Photoprotection of the Brazilian Society of Dermatology (SBD) recommends the use of sunscreens with a minimum sun protection factor (SPF) of 30 to protect against UVB rays. The organization also directs the products to be protected against UVA rays, which can be identified on the labels by "+" signs or by the words "UVA protection" or "Broad spectrum protection".
Not following these recommendations may have drastic consequences. Learn more below:
1. Skin Cancer
"There are three types of skin cancer: melanoma, basal cell carcinoma and squamous cell carcinoma of the skin." It is exactly the exposure to the sun that is responsible for their highest incidence, "says Luciana. aggressive is melanoma, as Giselle explains: "It is associated with potent exposure to the sun. Once the person is continually unprotected under the strong sun and in times of greatest danger, between 10am and 4pm, it is enough for the risk to develop this skin cancer. " Its first signs, according to Luciana, are changes in the shape or color of epithelial tissues (spots or spots on the skin) and, over time, spots that may form nodules or wounds. Fortunately, it is the least occurring in patients.
Carcinomas are more common and less lethal, and are linked to continuous exposure to solar radiation. They usually appear in areas most exposed to the sun on a daily basis, such as face, neck, ears, scalp and shoulders.
2. Actinic keratosis
Small, scaly lesions, easy to recognize by touch, which indicate that the sun has damaged the skin. According to the SBD, they appear more often on the face, ears, lips, backs of the hands, forearms, shoulders, neck, scalp and bald persons and can progress to skin cancer. > 3. Eritemas (sunburn)
The redness caused by UVB rays does not bring anything good. It is not aesthetically pleasing and causes pain. "It can still leave stains and scars on the skin," says Giselle.
4. Melasma and solar melanoses tend to get worse in the hottest months of the year, as there is no way to avoid direct or indirect exposure to the sun. These spots can be treated with whitening creams, peels or appliances in the dermatologist's office. "But the main thing is that in the summer, apply the sunscreen of broad spectrum or base tone, which better protect against visible light," recommends Luciana.5. DNA change of melanocytes
Excessive and unprotected sun exposure in childhood is a risk factor for the future development of skin cancer. This is because, as Luciana points out, "exposure to UV radiation may result in alteration of melanocyte DNA [melanin producing cells] and, consequently, an increased risk of cancer in new spots."
6. Photo aging (premature aging of the skin)
Aging is a natural process for every human being, but the sun accelerates the degradation of the skin. "What ages the skin, in the first place, is solar radiation," says Giselle. It continues: "The UVB beam penetrates directly into the cells, disrupting its renewal power." It's photoaging. Luciana emphasizes the visual effect of this: "The skin becomes rough, with irregular and thick texture, and has deep wrinkles and spots."
Over the years, the production of collagen (protein that gives firmness to the skin) naturally decreases throughout the body. Some external factors contribute negatively, the most harmful being excessive sun exposure and smoking. "The skin is not yellowish, it loses its elasticity and its support is flaccid," Luciana says.
The natural production of elastin (protein that forms the elastic fibers of the body) also falls over the years and is hampered by excessive exposure to the sun. "Thin and deep wrinkles appear," says Luciana. This is why Giselle teaches: "The sunscreen is the best anti-wrinkle that exists." Many people think that it needs expensive creams, but they only try to remedy the damages already caused. beautiful skin for much longer. "
British Journal of Cancer gives one more reason to stop smoking: smoking may also be related to an increased risk of developing leukemia and lymphoma. Research conducted by a specialist of Oxford University in England, followed 1.3 million adult women for 10 years. It was discovered that the cigarette was related to various diseases of the lymphatic system.
Several studies have already shown that eating too much red meat can be harmful to health. Now it has been pointed out as a risk factor for bowel cancer. This is revealed by a review of six scientific studies that will be presented at the American Cancer Society congress in the United States under the leadership of Alexandra Paola Zandonai, a specialist in oncology nursing at the University of São Paulo (USP).
