Claiming that the skin is made up of two layers, the sun is also divided in half as UVA and UVB rays, Dermatology specialist Dr. Işıl Kamberoğlu Turan said: “While UVB rays remain in the upper layer of the skin, UVA rays can pass through to the lower layer. UVA rays, which have an effect even on cloudy days and even leak through the glass, make up 95 percent of the ultraviolet rays reflected from the Earth’s surface.
These rays cause the collagen and elastin fibers, the supporting structures of the skin, which we call photoaging, to lose their texture and reduce the firmness of the skin. In addition, it is the cause of the complaints redness, itching, polymorphic light eruption, also called sun allergy. The pregnancy mask also causes dark spots on the shoulder, cheek and forehead and even recurrent skin cancer.
Turan stated that UVB rays make up 5 percent of the sun’s rays, saying, “They can’t pass through clouds and glasses, but they can penetrate the top layer of the skin. If we don’t provide a barrier against reactive oxygen radicals, they are responsible for tanning, sunburn, sun allergies and skin cancer When choosing sunscreen, both UVA and We should also make sure that it offers UVB protection.
Choosing the right sunscreen can sometimes be confusing. I would like to mention a few tips to pay attention to when reading labels. It is extremely important to write broad spectrum (broadband) for UVA and UVB joint protection. UVA Protection: Measured by PPD/PA, UVB Protection: SPF values. SPF has four different levels of protection. Low (6 -10 factors), moderate (15 -25 factors), high (30 -50 factors) and very high (50+ factors). So what do these SPF numbers mean? If a product with an SPF factor is applied to the skin, the burn time (how many minutes your skin turns red) is multiplied by the sun protection factor and the number of minutes you can stay in the sun without burning is determined.
So should we trust this? Never. The more you apply sunscreen, the better protected you are. For this reason, we recommend applying it 30 minutes before going out and renewing the creams every 2 hours. In the sea, water-resistant formulas are preferable during periods of extended aquatic life. Sunscreen should be reapplied after swimming, excessive activity and toweling off.
The protection response will also vary depending on your skin type. It still seems safe to prefer filters containing titanium dioxide and zinc oxide, which form physical barriers in pregnant women and children, but these creams leave a white color and a sticky texture. Physical filters reflect light, preventing light from being absorbed by the skin, but chemical filters absorb light and return it as harmless heat or light.
Among chemical filters, PABA, cinnates, salicylates and benzimidazoles are the most important UVB preservatives, while benzophenonans, methyl anthranilate and camphor compounds are effective against UVA rays. Colored sun filters come to the fore for impure skin; For sensitive skin with rosacea or redness, we recommend staying away from chemical filters.
Turan stated that a good sunscreen should have both UVA and UVB filters, water and sweat resistance, high protection factor content, accessible and sustainable cost, and ensure that it is non-allergenic. effective anti-aging cream is sunscreen. “For a special application, we definitely recommend choosing a product under the supervision of a dermatologist. Remember that skincare carries the magic of knowledge.”
