Almost all of us now know how important it is to use regular four-season sunscreen in terms of delaying skin aging and protecting against skin cancers. But as the summer months come, we need to refresh what we know about sunscreens. According to the researches, we wrote about the important issues that need to be known about sunscreens.
The average shelf life of sunscreen creams is 2-3 years if the box is not opened. However, they should be consumed within 9-12 months after opening.
Güneş koruyucu krem güneşe çıkmadan en az 15 dakika kadar önce cilde sürülmelidir. Eğer sonrasında hep güneşli ortamda bulunulacaksa 2 saatte bir, eğer kapalı ortamda bulunulacaksa 4 saatte bir tekrarlanmalıdır. Terleme, yüzme söz konusu ise saat beklenmeden cilt kurulandıktan sonra yenilenmelidir.
If there is no sunscreen factor in it, using a colored cream alone will not protect your skin from the sun. For this reason, when choosing your make-up materials, you should be careful to have at least SPF 15 in their content.
Lips, especially the lower lip, are one of the areas most damaged by the accumulating effects of the sun and where skin cancers are common. For this reason, it is very important to protect the lips with a special sunscreen in the form of a balm or stick that contains at least SPF 30 protection factor.
Sun rays can pass through windows of buildings and cars. Remember to use your creams even if you are at home and in the office all day.
Especially those with oily skin should prefer sunscreens in liquid or gel form, and those with dry skin should prefer sunscreens in cream form. If you are suffering from skin spots, you can also benefit from the concealer feature by choosing a sunscreen with a colored texture.
According to the researches, SPF 15 protects our skin from the sun's rays by 93 percent, SPF 30 by 97 percent and SPF 50 by 98 percent. It is as important as the SPF factor that sunscreen creams protect against both UVB and UVA rays.
Sunscreens are divided into two according to their sun protection properties: physical and chemical protection. There are titanium dioxide and zinc oxide among physical preservatives, and various organic chemicals in chemical preservatives. Physical protectors should be preferred for those with allergies, pregnant women, babies and children.
If there are care products, moisturizers or various medications that we use daily, we must first apply these creams to our skin. Sunscreen creams should be applied 15 minutes before going out for the last time, waiting at least 5 minutes between other creams.
Vitamin D is an important vitamin for our body. To avoid the harmful effects of the sun, it is sufficient to use cream after 10 in the morning until 5 in the evening. Apart from these hours, staying in the sun for about 15 minutes is sufficient for vitamin D levels.
