Sun protection factor (SPF) test is called values that show how sun cosmetics increase the natural protective function of the skin. For example, if the skin's natural protection time from the sun is 10 minutes, this time is tripled and extended to 30 minutes with a 3-factor sun protection product. Sun protection factors act as a shield against UVB rays on the skin thanks to their chemical structures. UVA filters create a protective wall against UVA rays, which accelerate the aging process of the skin. UVB filters stop the harmful effects and rays that cause sunburn.
It is very important that protective products protect against both UVA and UVB. The SPF statement on sunscreens gives detailed information about only its protection against UVB. Due to the harmful effects of sunlight, protection from UVA is very important. For an effective sun protection factor, the protection factor determined by the PPD method should be more than 1/3 of the protection factor determined by the SPF test method.
It is of great importance to pay attention to the SPF value when choosing a sunscreen to prevent possible skin problems. Harmful UV rays of the sun, which cannot be seen with the naked eye, are divided into two groups according to their wavelengths. They are ultraviolet A (UVA) rays and ultraviolet B (UVB) rays. When these rays come into contact with a person's skin for a long time, they damage the ordinary activities of skin cells, causing different skin problems to occur. At this point, it is possible to say that sunscreen products protect the skin.
Sunscreen products have various levels of protection depending on the amount of protective substances they contain. This level of protection is known as SPF on the product. However, the SPF value does not indicate the formula's protection against all UV rays contrary to popular belief. These values show only its level of blocking of UVB rays. However, the preferred product must provide protection against UVA rays for effective sun protection.
Exposure to sunlight for a certain period of time may benefit human skin, but excessive exposure to sunlight can cause very negative consequences. The sun is a very important source of vitamin D. The immune system and bone health are of great importance in this regard. Despite these positive effects of sun rays, they contain ultraviolet rays that are radioactive and damage the skin. Sun rays affect the lower layer of the skin and increase the signs and effects of aging. Additionally, excessive exposure to sunlight can cause skin cancer. Therefore, it is necessary to use skin care products that protect the skin against the effects of harmful sun rays.
SPF stands for sun protection factor. Sunscreen products should be used to effectively protect the skin from the negative effects of the sun. The most important thing to consider when choosing sunscreen is its SPF content. SPF means level of protection from light, medium and high sun rays. In this way, it becomes possible to protect the skin at the desired level and protect it from the negative effects of the sun.
Low factor sun protection products used in areas such as beaches are used for tanning. However, actively using products with low factor SPF may cause uneven skin tone and blemishes. The main reason why the statements on sunscreen products show different SPF values shows the rate at which the product reduces the effect of sun rays burning the skin. The values contained in SPF products provide protection depending on the time they are exposed to sunlight. Sunscreens with low rates such as SPF 15 and SPF 20 provide protection for a maximum of 1.5 hours. SPF 30 and SPF 50 provide protection for approximately 2 hours. When choosing sunscreen, it is a very important detail to pay attention to the SPF value on it.
The protection factors (SPF) on sunscreens are divided into three groups: light, medium and high protection. Accordingly, products with SPF 4 to 12 provide light protection, products with SPF 12 to 30 provide medium protection, and products with SPF above 30 provide high protection. The most well-known and preferred among these products are sunscreens with SPF 15, SPF 30 and SPF 50 values.
Sun protection can be provided by certain chemicals such as titanium dioxide in sunscreens. SPF values are determined according to the concentrations of these substances in their formulas. In fact, there is a difference of approximately 3% when looking at the percentage of protection between the two formulas that provide high and mild protection. However, this small difference has a much greater effect on the skin than expected due to the chemicals in the formula.
As the SPF value of the sunscreen increases, it is expected that the damage and burns that may occur on the skin will decrease depending on the duration of sun exposure. However, the difference between SPF 30 and SPF 50 is noticeably less in this case. For example, it is possible to provide 97% protection with SPF 30, while SPF 50 can increase this rate to approximately 98%. The most important point when using both products is to apply sunscreen regularly and sufficiently. Everyone should choose the SPF level that best suits their needs, depending on their skin type, sun exposure time and personal preferences. Another thing to consider is that the preferred sunscreen contains factors that provide protection against UVA and UVB rays.
Sunscreen is a product that provides effective protection when used correctly. The first application of this product should be 15-20 minutes before exposure to sunlight. This time is important for the product to fully penetrate the skin and create a protective layer. The cream is applied to the neck, face, legs, arms and other areas exposed to the sun. In general, using a teaspoon of sunscreen is sufficient for an adult. It is important to be careful when applying sunscreen, especially to areas such as the neck, face and ears. It is also important to apply sunscreen regularly between activities and to maintain sun protection after entering the water or sweating.
SPF analysis is an important guide to determine the protection factor of sunscreens. Thus, it is possible to choose the sunscreen that is suitable for your skin type and offers the highest protection.
