A study in the UK has suggested that some brands of sunscreen do not meet the protection claims written on them. Based on these claims, we have raised curious questions about sunscreens to experts.

A very interesting research has been done on sunscreens, which are an important shield for our skin. The UK study examined sunscreen from 15 different brands. Each cream provides the claimed levels of SPF and UVA protection it was tested to see if it did.

As a result of the analysis, it was found that the best-known and most used brands of sunscreen did not meet the protection claims written on them. For example, a brand of sunscreen specially produced for children, SPF 50+as advertised it didn’t cover. Another product failed UVA tests, failed to achieve the alleged success.

The failure of reputable brands in Tests has raised a concern that consumers may not always be able to trust that sunscreens will provide the level of protection they expect for themselves and their children. References according to the experts we have applied, the results of this study are quite doubtful.

Choosing the right sunscreen is crucial to protecting our skin from sunburn, aging and skin cancer, experts say. The proper amount of sunscreens is very important for the activity.

The Health Organisation recommends applying about seven teaspoons of sunscreen 15 minutes before going out for the whole body. Experts describe the effective amount for the face and neck as two teaspoons.

So, what are we going to do when sunscreen is so important to our health, and on the other hand, claims that brands cannot provide the protection they promise are on the agenda? Everything to wonder about sunscreens and their use Assoc. Dr. so we asked our dermatologist…


This study conducted in the UK may be commercial. A more detailed information is required for the evaluation of the study in scientific status. For example, when were these patients put on sunscreen? Because sunscreens to the sun it should be driven at least 20 minutes before departure. This time is needed to activate on the surface of the skin and provide the protection it claims.

Was it also driven in sufficient quantity? By saying enough amount, for example, two teaspoons of sunscreen should be applied to the face and neck. A decrease in the recommended amount means a decrease in protection. Physical and chemical using the recommended amount of sunscreens prepared with FDA and CE approved concentrations of filters will eliminate these doubts. Approved concentrations are terminologically tested and generally it is available in products with dermocosmetic status sold in pharmacies.

There can be no such situation as the values on creams do not reflect the truth, because the products of major brands are inspected by certified companies whose reliability has been recognized worldwide. However, this depending on the environment and conditions in which the tests are performed, sometimes changes in the values may occur. After all, these products are manufactured in a factory, and it is possible that problems will occur in some series. But on unequivocally inspected and approved products we accept that the values are correct. Other kinds of approach all medicine, etc. it can also cause increased doubts about products and cause people greater harm to themselves by not using these products. Already mentioned the firm that carried out the research was asked to be retested.


To choose a good sunscreen, you need to know the sun’s Rays briefly. The sun’s Rays are divided into 3 groups, mainly ultraviolet (UV), visible light and infrared rays. But it is largely responsible for the effects on the body it is UV rays. 95 percent of UV rays reaching the earth are UVA rays, while 5 percent are UVB rays. In general, UVA rays play a role in aging and spot development, while UVB rays are responsible for sunburn. Skin cancer both UVA and UVB rays, mainly UVB rays, play a role in its development. But in recent years, visible lights and infrared rays have also been shown to play a role in spot development and skin aging.


SPF is a unit consisting of the initials of the’ Sun protection Factor’, that is, the sun protection factor. It essentially refers to protection against UVB. The amount of UV that causes redness when you use sunscreen, unprotected is the ratio to the amount of UV needed for the same redness. Although it sounds a bit like a mixed proportion, we can sum it up as follows; for example, SPF 30 protection means that 30 times more UV exposure is needed to have the same redness it means there is.


3 million people get skin cancer every year in the United States alone. Sunscreens are perhaps the products that play the most effective role in reducing skin cancers. First look at the proven skin cancer effects the striking condition is prolonged exposure to the sun. Brunette ones may be glad they don’t have white skin, they may also think that UV exposure won’t be a problem. In fact is not the case. Everyone UV he is the direct interlocutor of his Rays.


The most important point when choosing sunscreen is that the product is not only UVB protection, but also UVA protection. UVA protection is a relatively newer concept. SPF shows protection against UVB, while PPD (Persistent Pigment Darkening), on the other hand, shows protection against UVA. A good sunscreen should show effectiveness against both. In addition, sunscreen suitable for the skin structure of people with dermatological problems, especially acne, rose, stain, sun allergy you must use. In addition to UVA, UVB protection, broad-spectrum sunscreens with physical filters should be preferred, especially in people with stain problems October. On the other hand, the effect when we use the product we bought in the previous year after a few years it decreases. In general, sunscreens should be consumed within a year after opening. In addition, it should not be left under the sun during use.


The right known mistakes as follows:

– Sunscreen can be applied once a day. Wrong! It should be repeated every 3-4 hours.

– Sunscreen can be applied outside. Wrong! It should be driven at least 20-30 minutes before leaving the house. Because sunscreen products are absorbed from the skin only during this time and become ready to function.

– It is enough to apply a high-factor cream. Wrong! High-factor creams can protect you to the maximum in a certain period of time. It must be repeated every 3-4 hours.

– Sunscreens don’t break ,I can use them until they die. Wrong! When buying sunscreen creams, remember to pay attention to the expiration dates on them. End use of active ingredients contained in creams after the date, the effect decreases.

– After leaving the sea, it must be exiled. Wrong! It should be applied at least 20-30 minutes before our skin absorbs the cream. So it must be banished before entering the sea. The reason it was driven 20-30 minutes before it went into the sun however, the effect of sunscreen decreases as time passes, depending on the skin type (the cream can absorb or vomit) or external factors. In studies, the optimal time is thought to be 20-30 minutes. Especially outside for a long time if it stays, it should be refreshed every 3-4 hours.


We recommend you to choose sunscreen that contains at least SPF 30 protection factors and is dermatologically tested, but also provides UVA protection. 50 protection if your skin type is too clear, blonde or red it is useful to choose a product that contains a factor. If you have blotchy skin, opt for combined products that also include a physical filter.


We do not recommend the use of sunscreen for babies under 6 months of age. Let them be more in the shade and protected with wide hats and clothes, and in the sun from 11:00 to 16:00 in the summer, as much as possible we advise them not to be exposed. Children between 6 months and 2 years of age need to use sunscreens with physical (mineral) filters decontamination. Children older than 2 years can use sunscreens with both physical and chemical filters. One another important period is the pregnancy period. During pregnancy, instead of chemical filters, physical, mineral filter sunscreens should be preferred.


Sunscreen is still the most accurate and easy to prevent skin cancer. But on some suspicions of zinc oxide and titanium dioxide, which are placed in some products to increase the protective property it attracts. In the 1970s, sunscreens were excluded from the American food and Drug Administration (FDA) and included in over-the-counter products. In this way, it did not pass the tests that modern drugs entered. Meanwhile, the sun in Europe is decaying ts preservatives continue to be considered cosmetic, remaining outside of the drug.

In one study, four sunscreens were tested on 24 people. Of the four products, two were sprays, one was lotion and the other was cream. From participants, sunscreens to 75 per cent of their bodies four times a day for four days they were asked to practice, and blood samples were taken from these people for a week. Even on the first day of blood samples, more than 0.5 nanograms of active ingredients per milliliter of blood, which the FDA determined, led to discussion of all products except the cream.

The result is not evidence that sunscreens are harmful. It is also possible that the amounts received are completely safe. Sunscreens are also still most important in preventing skin damage that can lead to skin cancer it is a component. However, this does not mean that the effects of absorption should not be controlled. The proposition that sunscreens that use zinc oxide and/or titanium dioxide are “generally reliable and effective” is true. These inorganic compounds in the body they are not absorbed and reflect the harmful rays of the sun.


Although it looks basically the same, sunscreens used for the body should not be applied to the face. Because alcohol-containing spray-style preservatives dry the skin of the face and can cause eczema. Dry skin cream, oily ones should use lotion or water-based sunscreens. For oily skin, perhaps the last thing to do is to make it airtight. But in recent years sunscreens have also renewed themselves, now less they are greasy and less dense. Therefore, their structure, which will be heavy on your skin, can cause blackheads and pimples, has decreased.

We can summarize the differences of lotion, cream, spray or stick products as follows:

Lotions: the biggest difference from creams is its thin structure. While creams are more rigid, lotions are thin. So it is more convenient to use a percentage.

It is necessary to drive frequently because the lip area is more vulnerable. Again, the eye area is also a very sensitive tissue that needs to be protected with these products. Otherwise, the cream may evaporate and lose its effect along with sweat it can cause burning in the eye or drying of the skin around the eyes.

Creams: sunscreen usually contains a small amount of SPF while being used for a darker complexion. In addition, the time to stay on the skin is longer than sunscreen and lotion.

Sprays (Sun Milk): they are absorbed by the skin very quickly. After the product is applied, it does not leave a feeling of greasy and white appearance on the skin.


Light-skinned people can sunbathe for 10 minutes on the first two days, 20 minutes on the next days, while dark-skinned people can sunbathe for 20 minutes on the first two days, 30 minutes on the next days without using any sunscreen. During this time, your body D enough time for him to synthesize the vitamin.


Tomato, carrot, spinach, apricot, etc. by adding foods, namely carotene and lycopene, you can provide natural tan. Routine exfoliation to eliminate dead cells and clusters references This method helps sunless tanning products penetrate the skin and ensures even tan throughout the body. Natural oils such as Sesame, apricot, cocoa, sweet almond oil protect your skin and are healthy you can get a tan.


Sunscreens have started to be banned, especially in summer areas where there are sensitive beauties such as coral reefs. Oxybenzone, octinoxate and parabens contained in some of them make this situation even more essential it makes. These components can accumulate in human and marine organisms over time. You can even more easily understand that this fear is not out of place when you consider that tens of thousands of people are going out to sea to swim at the same time.

You should wear shorts, T-shirts and hats to protect against UV. In this case, you will have less chance of wearing sunscreen. You will also contribute indirectly to the environment while making your life easier.
