Are you one of the people not fond or lazy of using sunscreen? Do you just use it when going to beach? Well, after you watch this video, you will definitely apply sunscreen everyday.
What you see is not really, what you get. You think you have a beautiful, flawless and smooth skin, then try to take a look at your face in an ultraviolet (UV) light. You can clearly see if your skin is healthy or not.
Thomas Leveritt, a US-based photographer, decided to show some volunteers what they looked like in ultraviolet light, using a special filter and camera set-up in a park in Brooklyn, New York. He uploaded this video to show the reactions of these people and to raise awareness regarding the importance of sunscreen.
Most of the volunteers were surprised by the freckles and spots that had not yet shown up in their face, but visible in the ultraviolet camera. These skin pigmentation or scientifically known as melanin are the signs of ageing and sun damage that we can’t ordinarily see.
Another more surprising is what a person looked like once they applied sunscreen. He let the people apply lotion in their face and it showed up like a black paint. It looks like a barrier that blocks UV light; same goes with a glass or eyeglasses.
Phil Plait, a science evangelizer, at Slate explains, "The camera detects UV from the Sun that’s reflected off people’s skin; the point of sunscreen is to absorb that UV so it doesn’t even reach the skin. Since no UV is reflected from sunscreen, it appears black in the video, even though in visible light it looks white. It looks like people are smearing crude oil on their faces, which is pretty funny."
He also elaborated about ultraviolet, “Ultraviolet is slightly higher energy than the bluest light we can see. It comes in three varieties: UVA, UVB, and UVC. These go from longest wavelength (lowest energy) to shortest (highest energy). The Sun emits far more UVA than UVB, and not a lot of UVC. That’s good: UVC has enough energy to kill cells. What little the Sun emits is mostly absorbed by the Earth’s air and the ozone layer.”
He differentiated UVA and UVB, “UVB is absorbed by ozone as well, but some gets through. Some small amounts are beneficial, triggering vitamin D production in the skin. If you get too much, though, it causes sunburn, destroys vitamin A in the skin, and causes cancer. UVA is less dangerous than UVB but still not great. Long-term exposure can indirectly lead to cancer (creating chemical compounds that are carcinogenic) and destroys collagens in the skin that “age” it.”
According to Plait, Leveritt used an AstroDon UVenus filter and a camera with a CMOS detector.
This video had already raised awareness for more than 2.7 million people.
