SPF and sun protection

With the abundance of sun protection products available in the market, you should understand what SPF is, what you need to know to be protected from the sun as well, definitely have 100% natural protection products used for body and face.
Who needs SPF 60 or 100 SPF?
When summer comes again, questions arise about sun protection cream. Obviously exposure to the sun is dangerous and everyone has to defend himself. Our personal choice is a hat but if you still choose sunscreen … this article explains the issue of protection coefficients, what they protect from and what not.
In recent years, the sun protection materials have been rising in SPF numbers so that by 2009 they have reached spf 100. Sounds great? Dermatologists say these are just numbers games designed to confuse consumers. (1)
SPF – sun protection factor – measures how much the product protects against ultraviolet rays, B rays – that is very short waves (UVB), which can cause sunburn. The SPF does not measure the protection from UVA rays that cause skin aging.
UVA, UVB?
The sun’s radiation includes the visible light without which life would not exist. In addition to the sun’s visible radiation, invisible radiation also comes in – mainly UV. UV radiation is divided into several areas UVA, UVB and UVC, where about 95% of the UV radiation is UVA radiation and the rest is UVB radiation. UVB radiation because of its wavelength is much more energetic and harmful but mainly to the outer layers of the skin, which creates the redness until the skin burns, but on the other hand the amount of UVA is significantly greater when the UVA penetrates the deeper layers of the skin and is responsible for the acceleration Aging of the skin, appearance of wrinkles to skin cancer. In the attached picture you can see the effects of radiation on the skin.

In fact, only in recent years has the scientific community begun to pay more attention to the very negative effects of UVA radiation and its connection to the aging of the skin and even different skin cancers. This means that the SPF measures only the UVB radiation, which is only part of the overall UV radiation, so this measure is only a partial measure.

How do I measure SPF?

A person exposed to the sun and turned red after 20 minutes, if applicable SPF 15 protection material, will be protected 15 times more than without cream (SPF 15) “Burn” after 5 hours.

In contrast to what is commonly thought of by the large numbers of SPF, their practical significance is marginal. In fact, SPF 100 blocks 99% of UVB radiation, while SPF 30 blocks 96.7% of UVB radiation. But usually the substances come down from the body with swimming and sweating and therefore it is recommended to protect continuously to apply the cream at least every two hours. Therefore, even if you are protected “100 times” theoretically, it does not matter much if after two hours a large part of the material has already dropped from the body.
Quantity is required for optimal protection in accordance with SPF
To get the SPF listed, it is necessary to apply about 30 cc to the body, which means that sunscreen should suffice for a few individual exits or even a single day to get the protection recorded, but that people usually save and use much smaller quantities when they go out to the sun.
A 2007 study found that using a small amount of cream reduces the protection much more than the amount saved (smearing half the amount provides protection as a root from the SPF listed, for example – with SPF 100 smearing half of the required amount provides protection of SPF 10(.
But even if we put the material protection from the sun and even at high SPF level, the feeling that there is no problem with long exposure to the sun direct error. Most of the protective materials do not effectively protect against UVA radiation, so the user may not turn red or “burn” quickly, but it is already known that it is likely to suffer long-term damage.
The FDA not long ago announce that only 2 materials from the 10’s used for sun protection are effective and safe titanium oxide and zinc oxide – the only sun block we use for our creams since 2010.(3)
Lavender Facial & Body Cream
Lavender’s protective products underwent rigorous tests in the best laboratories in Israel and with the approval of the Ministry of Health.
The products protect by physical defence of blocking of the sun’s rays and preventing their arrival to the skin. The protection is obtained by non-nano-ceramic particles and therefore there is no dangerous of particle penetration the body and stay for many hours on the skin and protect it from the sun’s rays.
Facial anti aging Sunscreen with red algae – Perfect face protection with a day cream that contains red algae that provides nourishment during the day in addition to protection. The red algae is a one of the most potent antioxidant in nature that penetrates well into the skin, nourishing fine lines and dry skin.
The Sun Protection Anti Aging Face Cream provides protection from UVB radiation at the SPF15 level, which is sufficient for daily use, including occasional sunspots (enough for 4 hours in direct sunlight). However, the cream blocks 99.9% (up to 100 times better than the standard requirements) from UVA radiation (the main radiation in offices, etc.) and therefore prevents the aging of the skin and the appearance of long-term skin problems.
High protection cream – Provides UVB protection at the level of SPF20-23 and provides excellent UVB protection with 99.9% (up to 100 times better than standard requirements) from UVA radiation, thus preventing aging and long term skin problems.
In conclusion
Solar radiation has a significant amount of UV radiation, which is not filtered by the creams with the protection factors, and the high protection coefficient is not very significant in terms of the protection it provides, and it is much more important to apply the protection materials frequently and generously. From direct sun exposure – wear a shirt in the sea and go with a hat in the sun.
