I'm pretty sure this product is just a gimmick, but check it out for a laugh. It's meant to protect you from the aging effects of high intensity visible light from your computer screen.

What do you think? Is there even a grain of truth to the concern that HEV light might be damaging?

    Interesting Sonja_Hopeful ! 

    I am thinking of using some light sunscreen for day use and perhaps home too.
    Dermatologist, Dr. Bindu Sthalekar did share that we need to use sunscreen every day! We can get it even from computer screen, you can check out her video on youtube. I know for a fact a celebrity dermatologist sleep with sunscreen too. You get it from light bulb. Indoors. Not just from the sun. Not too sure the science behind it or how much "problem" it causes. 

    Just went out today and got burnt despite using a high SPF50+ sunscreen (double coats of more than 20% zinc), 5" brim floppy hat and UV400 sunglasses. Australia sun is brutal. I applied another thick sunscreen that is more water resistant under my eyes and sensitive areas. The max UV rating today is rated at 6, and it is not even summer, spring has just started. I have very fair skin and get burnt easily. Normally i would avoid going out during peak hours as you can see in the screen shot of the Sunsmart app on my iphone. Peak hours today is 9am - 2.40pm but i had to go to the airport to pick my husband. 

    btw this is today's weather

    Recovering with lots of snail slime now and hiding in the dark. 

    I am thinking of limiting my acid and tretinoin use during summer to limit photo sensitivity.
  • @Sonja_Hopeful Visible and infrared light also will cause formation of free radicals in skin, although normal sunscreen ingredients only protect against uv-radiation. Pigments like iron oxides, titanium dioxide etc do however protect against visible light, and so do antioxidants like vitamin c, vitamin e, niacinamide etc. Most light bulbs indoors and computer screens don't emit uv radiation, and if they do it's negligible. They do emit other wavelengths of course. If you apply creams with antioxidants they need to be there in sufficient high concentrations, and most of them need to have air tight packaging.

    That is so insightful! Can i pick on your brain regarding this i read in

    For total protection against damage from the sun, the skin needs to be protected from UVA, UVB and IRA (infrared light).

    • ultraviolet A (UVA) (320-400 nm)

    • ultraviolet B (UVB) (290-320 nm)

    • infrared A (IRA) (760-1440 nm) 

    UV radiation only accounts for approximately 7% of the sun’s energy.  Roughly 33% of solar energy is IRA (What is Needed for a Sunscreen to Provide Complete Protection by Schroeder, P; Krutmann, J)

    • What ingredients should we look at for Complete Photoprotection?
    • If UV is 7% and IRA is 33%, what about the remaining 60%? eg other additional wavelengths contribute to skin damage?
    The article talks about  antioxidants, osmolytes, and DNA repair enzymes7,8 (e.g., photolyase and T4 endonuclease V) to use in addition to sunscreen. Also mentioned polyphenols (e.g., flavonoids and procyanidins) in addition to Zinc Oxide (sunscreen filter). 

    Beauty Brains spoke also about using hats for added sun protection.

    Thanks in advance! I don't know too much as i do not have science background.

    typo. i meant "pick your brain" not "pick on your brain". :( opps
