Can you still use expired sunscreens? Do you know how often you need to renew sunscreen?
Like everything in life, the sun has its pros and cons. We get vitamin D, one of the most important vitamins for life, from the sun. However, the sun’s radioactive rays can cause sunburn or skin cancer. That’s why sunscreen is a must, no matter what your skin tone is! Of course, there are many facts you need to know when using sunscreen. For example, what kind of creams should you prefer if your skin is sensitive or what should you do to avoid white spots on your skin? Today we will talk about 23 facts you should definitely know about sunscreen. Now let’s get to the details without wasting time;
1)There is a difference between chemical and physical sunscreen
Chemical sunscreen absorbs UV rays before they penetrate the skin. Physical sunscreen, on the other hand, reflects ultraviolet (UV) rays away from your skin.
2)People with sensitive skin should use special sunscreens
These people should especially choose mineral sunscreens containing zinc oxide or titanium dioxide, as the chemical ones can irritate the skin.
3)The label “broad spectrum” indicates that the sunscreen you buy can block both UVA and UVB radiation
4)Applying enough sunscreen is very important for sun protection
If you apply less sunscreen, the SPF drops.
5)UVB rays are a type of UV ray responsible for sunburn
Dermatologists generally recommend buying sunscreens with an SPF of 30, as they protect your skin from 97% of the sun’s UVB rays.
6)Sunscreens block UVB light. UVB light helps produce vitamin D, but using sunscreen does not lead to vitamin D deficiency
7)When sunscreen expires, it no longer has UV protection
In other words, using expired sunscreen can lead to sunburn or skin cancer.
8)Franz Greiter invented this cream after being sunburned while climbing a mountain on the Swiss-Austrian border in 1938
9)Although we always neglect it, it is also necessary to apply sunscreen on the lips
You can also protect your lips from the sun by using a lip moisturizer or lipstick with an SPF of at least 15.
10)Relying on sunscreen alone is not enough to protect yourself from the harmful effects of the sun
Dermatologists also recommend wearing sun protective clothing and avoiding direct sun exposure during the peak hours of UV rays (10:00 – 16:00).
11)UV rays can pass through window glass
That’s why you should use sunscreen even when you are at home.
12)UV rays can hit your skin even on 80% cloudy days
13)Oily sunscreens can clog pores and cause acne
14)Whether you use a physical or chemical sunscreen, you should apply it about 20-30 minutes before going outside
15)Most sunscreens irritate your eyes because they contain a substance called avobenzone
This substance is added to sunscreens that convert UV rays into heat, which is less harmful to the skin.
16)Sunscreens containing retinol not only protect your skin from the sun’s UV rays, but also prevent wrinkles thanks to retinol’s anti-aging effect
17)You can tan even with sunscreen
18)Reapply sunscreens every two hours
19)Sweating or swimming erodes the protective layers of sunscreens
20)Some clothes, such as cotton and linen, have a poor ultraviolet protection factor (UPF), so you may need to apply sunscreen under clothing
21)No white marks on your skin if you use chemical sunscreen
22)Sunscreen is not recommended for babies under six months of age
It is best not to directly expose babies to the sun.
23)When using spray sunscreen, you should spray it on your hands, not directly on your face, to avoid irritating your eyes and lungs
