What exactly does SPF sunscreen do for everyone?



Sun Protection Factor (SPF) is a measure of how well a sunscreen will protect skin against UVB rays. UVB rays are the kind of radiation that can lead to sunburn, skin damage, and skin cancers. Most people are concerned about whether a high-SPF sunscreen will protect the skin more than a low-SPF one. It is difficult to give a short and simple answer to this question. Dermatologist and photobiologists have long been studying the side-effects the sun’s ultraviolet (UV) radiation on the skin, and they were looking for ways to protect the skin them. Hence, we will inform you about a few important points to help you in selecting the SPF of your sunscreen.

Types of Ultraviolet Rays

We cannot see ultraviolet light, due to its shorter wavelengths than the light we can see. In the UV spectrum, there are two types of rays that can damage the DNA of skin cells and cause skin cancer. Hence, it is necessary to protect your skin against both of these rays: Article source

  • UVB rays can lead to sunburn and they have a key role in causing skin cancer. The SPF number on the sunscreen refers to the amount of UVB protection it provides.
  • UVA rays can lead to tanning as well as skin aging and wrinkles. They have the shortest wavelengths that cause sunburn. In your search for the best sunscreen, you should look for the words “broad spectrum”, which means that its ingredients can protect against both UVA and UVB rays.

What Does the SPF Number Show?

The SPF number you can see on all sunscreen creams show the time required for the sun’s UV radiation to redden your skin when using the product compared to the time without applying any sunscreen. Therefore, a sunscreen with SPF 30 would take you 30 times longer to burn than without sunscreen.

This sunscreen will allow only 3% of UVB rays to reach your skin. A sunscreen with SPF 50 will let about 2% of sun rays reach your skin. Although the percentage is small, you need to consider that SPF 30 allows 50 percent more UV radiation to your skin.

Under normal conditions, a sunscreen that has a higher SPF and broad-spectrum coverage provides a higher level of protection against UVA damage, sunburn, and DNA damage in comparison to the ones with lower SPF. However, products that have higher SPF can often lead to a false sense of security. It means that people tend to stay out in the sun much longer when they use these SPFs. They may also skip reapplying the sunscreen because they think that the high-SPF can protect them against the sun for as long as they wish. The result is that they end up with more UV damage and skin cancers.

What Is the Best SPF?

The Skin Cancer Foundation suggests using a water-resistant, broad-spectrum sunscreen with an SPF of 30 or higher if we are exposed to the sun for an extended period of time. Regardless of the SPF, it is necessary to apply about two tablespoons of sunscreen 30 minutes before exposing your face and body to sun rays and apply it again every two hours.

Final Words

So far we have talked about the types of sun rays and also the role of SPF in protecting the skin against the sun. The question asked in the title might be considered a wrong one. We should have asked about the best way to protect our skins against the sun. There are various ways to protect the skin and sunscreen is not the ultimate protection against sun rays. It is important not to rely on the SPF number printed on the sunscreen’s label. Sunscreen is just one part of a strategy that need to be included in your skincare routine. Staying under the shade and covering the body with suitable clothing such as wide-brimmed hats and UV-blocking sunglasses are among other strategies to enjoy healthy skin even after exposure to sun rays.

Maestro de Braga is the first Portuguese in the National Symphony Orchestra of Cuba.

Maestro Filipe Cunha, Artistic Director of the Philharmonic Orchestra of Braga, has been invited to conduct the Cuban National Symphony Orchestra, as announced today.

According to a statement sent by O MINHO, “he will be the first Portuguese conductor to conduct this orchestra in its entire history.”

In addition to this orchestra, the maestro will also work with the Lyceo Mozarteum de la Habana Symphony Orchestra.

The concerts will take place on 4 and 12 March 2023 at the National Theater of Cuba in Havana.

In the words of the maestro, quoted in the statement, “these will be very beautiful concerts with difficult but very complex pieces” and therefore he feels “very motivated”.

From the very beginning, Rachmaninoff’s Piano Concerto No. 2 will be performed by an Italian pianist (Luigi Borzillo), whom the maestro wants to bring to Portugal later this year. In the same concert, Mendelshon’s First Symphony will be performed.

Then, at the second concert, in the company of the Mexican clarinetist Angel Zedillo, he will perform the Louis Sfora Concerto No. 2. In this concert, the maestro also conducts Tchaikovsky’s Fifth Symphony.

“This is an international recognition of my work. An invitation that I accept with humility and great responsibility. I was surprised to learn that I would be the first Portuguese member of the Cuban National Symphony Orchestra. This is a very great honor,” the maestro said in a statement.

“I take with me the name of the city of Braga and Portugal with all the responsibility that goes with it, and I hope to do a good job there, leaving a good image and putting on great concerts. These will be very special concerts because, in addition to performing pieces that I love, especially Rachmaninov and Tchaikovsky, I will be directing two wonderful soloists who are also my friends. It will be very beautiful,” concludes Filipe Cunha.
