Many people do not care about the existence of sunscreen, many people also do not know how important to use sunscreen. This needs to be realized, especially people who live in the tropics. Using sunscreen aims to protect the skin from harmful UV rays for the skin.
In fact, according to the Skin Cancer Foundation, through Dr. Tony Yuan, clouds have filtered less than 25% of UV rays that penetrate your skin to cause skin cancer. Dr. Tony Yuan still said that, although you may feel colder on a cloudy day, your skin will still absorb most of the UVA and UVB rays.
UV radiation is part of the electromagnetic (light) spectrum that reaches the earth from the sun. It has wavelengths shorter than visible light, making it invisible to the naked eye. These wavelengths are classified as UVA, UVB, or UVC, with UVA the longest of the three at 320-400 nanometers (nm, or billionths of a meter). UVA is further divided into two wave ranges, UVA I, which measures 340-400 nanometers (nm, or billionths of a meter), and UVA II which extends from 320-340 nanometers. UVB ranges from 290 to 320 nm. With even shorter rays, most UVC is absorbed by the ozone layer and does not reach the earth (Epstein & Wang, 2017Â - retrieved by skincancer.org).
During this time, people (especially women), instead use day and night creams, anti-aging serum, and moisturizer more often, but neglect to use sunscreen. No matter how expensive the price of the moisturizer and cream is, if the skin is not protected from the effects of rough sunlight, it will affect acne, psoriasis, darkening skin (tanning) and some other skin damage. Because ultraviolet light has three contents, among which are mentioned above: UVA, UVB and UVC.
Which is even more dangerous, UVA rays can also damage the DNA that triggers the occurrence of cancer. While UVB effect on premature aging, such as wrinkles and black spots.
Another component is UVC which is often touted as a cause of skin cancer. However, in research at Tokai University School of Medicine in Japan, cancer therapy can use ultra violet C (UVC). With such light therapy, the condition of cancer cells may weaken.
Meanwhile, the benefits that are rarely realized in using sunscreen, which was discussed at Unity Point Health - John Stoddard Cancer Center, among others:
- It keeps you looking young
If only, the main cause of premature aging of facial skin and body skin is ultraviolet exposure? So by wearing sunscreen, facial skin and body skin will avoid wrinkles and rough skin.
- Sunscreen keeps your skin tone
In addition to avoiding skin aging, sunscreen also prevents black / brown spots on the face and skin discoloration.
- Sunscreen can be used for all skin types
If you have non-flammable skin, wearing sunscreen is still important. Sunburn is a quick reaction, but sun damage happens throughout life. Despite the fact that skin cancer is more common in people with lighter skin, it does not mean it can not affect those whose skin is darker.
- Using sunscreen will actually make you more comfortable
The active ingredient in sunscreen works with infrared rays of ultraviolet (UV) light, to prevent and eliminate from reaching deeper skin layers. Sunscreen is available in various forms of cream, lotion, gel, spray, and lip balm.
Then according to Dr. Natasha Cook, a dermatologist from Australia, use a sunscreen containing SPF and which has a PA ++ label. PA ++ label can protect skin from UVA rays that can trigger cancer on the skin. In order for maximum benefits, use sunscreen is 30 minutes before you go out in the sun.
