The harmful effects of the sun on the skin, this everyone knows.Therefore, all dermatologists recommend applying sunscreen every day regardless of whether or not it.
Và thực tế, không chỉ mỗi ánh nắng mặt trời, mà có một tác nhân khác khiến làn da lão hóa không phanh. Nguy hiểm nhất là chị em lại lơ là, không hề hay biết mà vẫn để tác nhân ấy gây hại cho làn da ngày này qua tháng khác. Đó chính là ánh sáng xanh từ các thiết bị điện tử như điện thoại, máy tính...
Ánh sáng xanh gây hại cho làn da như thế nào?
The blue light emitted from the phone screen and the computer ... is called HEV, with the level of harm on the skin equivalent to the sun.Blue light will also cause dark skin, darkening, wrinkles, melasma and decline in collagen in the skin.
Even blue light also causes heaviness than UVA rays because you are almost unaware of what skin is suffering or affected.Because the skin is not red, burning as exposed to the sun.
Ánh sáng xanh làm tăng nhanh quá trình lão hóa da vì nó kích thích da tạo ra các gốc tự do, chúng thoát khỏi lớp bảo vệ tự nhiên của da và gây ra tổn thương DNA của da vĩnh viễn. Tổn thương này cũng giống như cháy nắng, nếp nhăn do tiếp xúc lâu với ánh nắng mặt trời, thậm chí nghiêm trọng hơn là ung thư da.
Dr. Vasselli explained: "One of the biggest problems is not the intensity and wavelength of UV rays but because you are not fully prepared.Usually in the evening after turning off the lights before going to bed, you still use a lot of your phone, or sit on the computer for hours.Although it may be less harmful than UV rays, you will avoid UV rays, not blue light".
Indirect blue light is harmful but as dangerous as the sun
The indirect harm of blue light is often overlooked, such as: using mobile phones for a long time, even sleeping without turning off mobile devices at night, causing the rhythm of biological clock to adjust the sleep.Sleep is interrupted.
Moreover, at night, the skin needs to rest and recover, especially from 11 pm to 4 am, this is the time when skin cells will fight free radicals that cause aging,increase collagen and elastin.If you still use your phone and computer until late at night, the skin cells will not recover as planned, leading to increasing skin dark, pale, old.
There are also green lights for the skin
Blue light not only has a negative effect, like ultraviolet rays are also beneficial and can effectively disinfect.Dr. Alessandra Vasselli concluded: "Blue light is very effective to combat bacteria that cause inflammation, but they are skin scanners with modern technology and a professional treatment, not using phones, computers but hope skin skinHealed ".
Conclude
So the most needed now is to minimize the time to use the computer, the phone so that the blue light does not affect too much on the skin.Pay attention to applying sunscreen regularly, 2 hours so miles once if you often have to sit with your computer.
And pay attention not to use the phone too late, especially when the lights have been turned off but still use the computer, this is also twice as harmful because the blue light will focus all on the face and eyes, the level of causingHarm will increase many times.
