UV rays are good for skin health, but only in moderation. SPF products help to limit their impact and protect the epidermis from burning. It is important to be able to correctly select and apply this cosmetics, to distinguish an effective product from low-quality creams.
sun protection factor
There are two types of radiation – A and B. The first type (UVA) does not cause burns on the skin and its redness, but causes maximum harm in the form of accelerating photoaging and provoking the development of cancer. An excess of the second type of rays (UVB) is accompanied by hyperemia and blisters on the epidermis, a burning sensation and itching. SPF protection works exclusively against B-radiation. Cosmetics with UVA filters are additionally marked with the PPD index.
The SPF value shows how many times the skin becomes more resistant to sun exposure. For example, the number 50 next to the protection factor means that the epidermis, lubricated with cream, will safely withstand 50 times more UV-B rays than without cosmetics. Funds with SPF should not be used to extend the stay on the beach, especially between 10 am and 4 pm. They are designed to reduce the risk of burns when forced to stay under the influence of ultraviolet radiation.
Sunscreen SPF 15
Products with the specified value of the protective factor provide a high degree of radiation filtering. Sunscreen SPF 10-20 guarantees about 95% UVB reflection. At the same time, the considered cosmetic product increases the skin’s resistance to negative effects by 15 times. This sunscreen is perfect for urban residents who are forced to stay under the sun for a long time. People with dark skin can take SPF 15 to the beach, it is better for owners of “porcelain” epidermis to purchase other preparations.
Sunscreen SPF 30
Cosmetics with the described value refers to intensive protective agents. SPF 30 face sunscreen is more commonly recommended, but there are similar products for the body. The filters in these preparations reflect approximately 97% of ultraviolet rays. SPF for face or body 30 increases skin resistance to UVB by 30 times and prevents skin burns. The presented cosmetics are considered universal, because they are well suited for any color types.
Sunscreen SPF 50
This product is also called a sun block, it provides protection from 99.5% of UV type B. SPF 50 facial sunscreen with an additional PPD label will help prevent photoaging of the skin. These agents prevent the development of melanoma and squamous cell dermal cancer. A sunscreen with a protective factor of 50 is the most intense product in this segment. It is suitable for both owners of swarthy and very fair skin.
Sunscreen SPF 100
The above facts indicate that a protective factor value greater than 50 is a standard marketing ploy. You should not buy such a sunscreen – no cosmetic product can filter 100% of ultraviolet rays. The products described often do not meet medical quality criteria and contain a lot of parabens, which cause even more damage to the skin than ultraviolet light.
Composition of sunscreen
Before buying the cosmetics in question, it is important to carefully study its ingredients. They mainly characterize sunscreen – which is better and safer, protects the skin from UV radiation more intensively. Good tools have two types of filters:

- Chemical – benzophenone, octinoxate or avobenzone. Such components are absorbed into the skin and theoretically convert the energy of the sun into heat, protecting from both types of ultraviolet radiation (A and B). While there is no medical evidence for this process, therefore, dermatologists recommend careful use of sunscreen with chemical filters.
