7 Errors in sunscreen that may decrease protection

7 Errors in sunscreen that may decrease protection

Awareness about using sunscreen to ensure healthy skin always makes a difference and many people are constantly on the lookout for making a mistake when it comes to applying the product. However, some bad habits, which may go unnoticed, persist and even compromise the effectiveness of the sunscreen, leaving the skin unprotected.

One of the most common mistakes is to remember to use sunscreen only in summer, when you go to beach or pool. Dermatologists are emphatic in claiming that daily sunscreen use is essential during all seasons, regardless of the weather of the day.

According to dermatologist Selma Cernea, Hospital Israelita Albert Einstein (SP), exposure of the skin to Sunscreens without the proper use of sunscreen can cause a variety of problems, ranging from the appearance of spots, dryness, loss of elasticity and early aging to severe illness.

"The application of sunscreen works as a barrier to penetration of ultraviolet rays, which can cause a lot of changes, "she explains.

Check out other mistakes you need to eliminate from your routine:

Do not choose the right sunscreen for your skin type

Opt between the different types of sunscreens - which can be found in the form of cream, gel, spray and serum - and to define the ideal Sun Protection Factor (SPF) is very important for the skin health. Factors such as the type and tone of your skin, age and tendency to dermatological problems, such as blemishes and acne, need to be taken into consideration.

"To protect your skin, creamy lotions are the most appropriate. If it is oily, the use of gel, gel-cream or oil-free lotion is more appropriate. "For dry skin, it is more appropriate to use cream", exemplifies Selma.

When the question is the choice of the SPF of the sunscreen, the darker the tone of the skin, the greater the amount of melanin produced by it and consequently, greater natural protection against sun damage. Therefore, the clearer the skin, the greater the Sun Protection Factor indicated to it. The ideal is to consult a dermatologist so that the professional can determine the correct FPS. But always keep in mind: both light and dark skins need to be protected from the sun with the use of sunscreen!

Do not reapply the sunscreen properly

Another common mistake in the use of sunscreen is incorrect product reapplication. Many people believe that it is not necessary to reapply sunscreens, which nowadays are water resistant, and spend many hours at a time exposed to the sun, perspiring and getting wet, without re-passing the product. solar protection when you reach the beach.It is necessary to reapply the filter every 2 hours, especially when you are perspiring and having contact with water.Products come out more easily in these cases.Even the protectors made for practicing sports, which have anchoring bigger, can not stay in the skin for so long if the person stays for long periods in the water, "explains dermatologist Daniela Lemes, a member of the Brazilian Society of Dermatology (SBD).

Only make use of sunscreen

There are in the market several types of makeup with sun protection, which are great options to increase the daily protection of the skin, but that do not require the use of sunscreen. Dermatologists indicate that makeup with a sunscreen factor is always used over the sunscreen.

Forgetting to protect certain areas of the body

Many people have the custom of applying sunscreen only to the most obvious parts of the body, neglecting more 'hidden' areas such as the nape of the neck, armpits, ears, hands and feet.

According to dermatologist Leonardo Spagnol Abraham, a member of the Brazilian Society of Dermatology, sunscreen should be used every day before sun exposure on all skin that will have direct contact with the sun's rays. "Any area that could be exposed directly to the sun should be protected with the sunscreen. We can not forget the ear, neck and neck, "he says, noting that eyes should also be protected with sunglasses with UV protection.

It is worth remembering that although some tissues act as a barrier, protecting the skin from lightning sunscreen, the sunscreen should still be used as this protection depends on several factors such as fabric type, fabric density and color, for example.

On the beach or in the pool this recommendation becomes even more important. Lemes recommends that when at the beach or in the pool, it is best to wear a protective suit before wearing a bathing suit. "You should wear a bikini or bathing suit as your bathing suit may leave the place and cause a burn in area in which you did not apply the protector, "she explains.

Neglecting the scalp is also a serious mistake:" The scalp, especially of bald men, needs as much sun protection as the rest of the skin. This area is very incident of basal cell skin cancer in adulthood. People with little hair or thin hair should wear a hat or cap to protect the scalp, "says dermatologist.

Save on the amount of sunscreen

The very economical application of sunscreen, using small amounts of the product, can also compromise its effectiveness, according to Selma Cernea.

According to the Brazilian Society of Dermatology, the amount of sunscreen indicated for each part of the body is:

one teaspoon of sunscreen on the face, neck and on the head

  • one teaspoon of protector for the front of the trunk and one for the back
  • one teaspoon for each arm
  • one teaspoon to the front of each
  • According to SBD's recommendation, the application of the filter should occur between 20 and 30 minutes before sun exposure. However, some products currently available on the market present immediate action

Overdue product

Dermatologist Selma Cernea also points out that it is essential to check the expiration date of the sunscreen. Many people have the habit of saving the product after the end of the summer to redeem it only the following year, without checking if the product is overdue.

The first problem in this situation is that wearing sunscreen is mandatory all year round . In addition, the overdue product can pose a variety of health risks: when sunscreens are out of date, and the protection index decreases and does not protect the skin properly, there is still a risk that its use will trigger skin problems such as dermatitis of contact, swelling, blisters and redness. This is because these products have in their formulation compounds that are degradable.
