It has been well known for some time that using sunscreen every day is not only the best anti-aging method, but also prevents the effects of aging. UV raysIt can damage the dermis even on cloudy days.
Now there are a number of doubts revolving around the proper use of sunscreen, which Infobae set out to clarify with experts.
To begin with, dermatologist Velia Lemel (MN 66,657) pointed out: “Unfortunately, many people only remember the importance of sunscreen at this time of year because pool and beach season begins, the sun is stronger and the days are longer. and emphasized that it should be used before leaving the house throughout the year, as the sun does not have a holiday during the winter months.

during the pandemic COVID-19 increased awareness of the importance of exposing yourself to the sun during the hours allowed for synthesis. Vitamin DIt is an essential nutrient for strengthening the immune system and preventing viral and bacterial respiratory infections. Being in the sun strengthens bones and teeth, balances cholesterol, lowers blood pressure, banishes depression, and fills us with energy, among other benefits.
But the sun is also the main cause of skin aging and increases the likelihood of developing skin diseases.
“excess unprotected sun It can have very harmful effects: The most well-known long-term consequences are premature skin aging (spots and wrinkles), increased number of moles, skin cancer and various eye disorders. Dermatologist Lilian Demarchi stressed that “when speaking of protection, it means not only the use of skin and sunscreen, but also the use of glasses, lip balm with protection factor, a hat and appropriate clothing.”
Dermatologist and Avène scientific advisor Cristina Pascutto (MN 57831) agreed with them, saying, “While it is important to know that light protection is necessary all year round, when sun exposure starts to become more frequent and more intense, maximize care”.
What should be considered when buying sunscreen?

Consistent with the above, Pascutto states, “when purchasing a sunscreen, skin typeIt depends on the phototype, as they are not all the same in the sun”.
And he expanded: “This is defined by skin colour, hair colour, sunburn propensity, and ability to tan. These traits are genetically programmed. Our very white skins that turn red and never tan, our other white skins that turn red but lightly tan, our dull skins that turn red but get a golden tan. and we have darker skin where tanning occurs from the beginning of exposure”.
“After we know ourselves phototype Now we can choose the protection – dermatologist recommended – that best suits our natural sensitivity to the sun. The market offers a large number of products that provide efficacy and safety; You should choose broad-spectrum ones that cover UVB, UVA and blue light rays”.
And after reassuring that “there are now sunscreens with state-of-the-art active ingredients like Tinosorb that extend its photoprotective power to high-energy blue light,” he also highlighted: Formulas are available for dry, seborrheic, acne-prone skin.that is, it has excellent cosmetology”.
To summarize briefly, “For dry skin cream formulations are better, for oily skin emulsions or always oil-free sprays may be preferred, as for acne-prone skin. Sensitive skin, on the other hand, should use products developed for this purpose, generally based on mineral filters and with the texture of the relevant biotype, while normal skin should prefer emulsions.

Tips for better photo protection
It’s good to know that using sunscreen once purchased “doesn’t mean 100% protection,” according to Pascutto, because “generally not enough is applied, reapplied as it should be, and swept away.” with hours and sweat”.
Here is the first piece of advice for you: “When applying sunscreen, quantity must be substantialwithout forgetting the neck, décolleté, backs of hands and feet and scalp in bald men, without missing, equally, without forgetting. Apply half an hour before going out in the sun, repeat every two hours and after each bath or if you sweat a lot.
“One of the most common mistakes is to use a higher protection factor for the face than the body (for example, using factor 20 for the body, factor 50 for the face),” said Lemel. It should be taken into account that moles can appear anywhere.
And at this point, “it never hurts to remember that,” for Lemel, although it is known that there are times when direct sun exposure is not recommended. “The hours to avoid the sun are from 10 am to 4 pm, when the radiation peaks at noon, when the sun’s rays fall perpendicular to the earth,” the dermatologist said.The effect of sunscreen lasts for two hours. Measurements of the protection factor and SPF 30, 50 or 60 are always taken with two hours, so it is important to repeat the application every two hours and if we are in water it is necessary to repeat the application. more often unless it’s a waterproof solar one.”

Regarding whether a sunscreen that was opened last summer can be used, Pascutto said, “Many sunscreens are from the previous summer and although still valid based on their expiration date, they are not recommended for use because they have been on for a long time. they stayed”.
Finally, a very common tradition is to use the same protector for the entire family group; In this regard, the dermatologist explained that “children’s sunscreen can be used on adults, but not vice versa” and rightly said: “Sunscreens can be used on adults. child They are fragrance-free, highly water-resistant and have an anti-aggressive texture, creating extra protection after application to protect the skin from sand, pool chlorine or sea salt”.
In this regard, Demarchi says, “cosmetics is what transforms from a product for adults into a product for children. And above all the formulation, if these are sprays, creams, etc. if”. It can be used regardless of age, if an adult sunscreen does not contain anti-aging, anti-pigmentation active ingredients or does not add anything that the child does not need. Child protectors have no colour, fragrance and are for sensitive skin.that is, the protection does not change except how the final product is formed”.
