Does this eliminate 99% of both UVA and UVB a rays?

Yes it does, I've had it on my windows for over 10 years and there is no fading in that room

It appears to have a UPH rating of 50, which equates to blocking approximately 97.5% of UV rays. http://babybeachtents.net/genji-sports-pop-up-family-beach-tent-and-sun-shelter-review

My thought was yes. UVC is a short wavelength and that is why it is blocked by our atmosphere. So it is easily blocked by glasses and probably plastic as well, especially plastic that we know blocks UVA and UVB rays. Here something from Wikipedia: Ordinary glass is partially transparent to UVA but is opaque to shorter wavelengths, whereas silica or quartz glass, depending on quality, can be transparent even to vacuum UV wavelengths. Ordinary window glass passes about 90% of the light above 350 nm, but blocks over 90% of the light below 300 nm. So with resonable confidence yes they block UVC, which is what germicidal lamps put out. Watch out for your exposed skin though.

No, 99.3% of the UV produced by the bulbs is blocked for safety. Vitamin D from Sun exposure is due to the UV and bright light therapy is believed to work through the bright light hitting the retina and causing changes in the actions of the pineal gland. Please make sure to check legitimate medical sources for more detail and authorative information.

All of your hand that is covered would be blocked from the rays, so I wold estimate approximately 90%. Imagine yourself suntanning with a robe on, wherever the sun is able to tan you that is where the rays will go. It's the same with the gloves. There is minimal exposure even without the gloves but some of your clients (if your are a professional) may be sensitive to the rays. The UV rays sometimes cause certain clients to itch after a few layers of gel polish, but not while wearing these because the most sensitive parts of your hands are covered. These also come in handy when a client has on rings that can not be removed. The rings don't burn or anything, but I don't like placing a clients hands under the lamp with jewelry on so I use the gloves. I am a nail technician and licensed cosmetologist and not a scientist or doctor, therefore my response is based on observance and trial and error, but not clinical studies. If you would like further information about UV ray exposure, I would suggest you google it based on the wattage and lamp if you are concerned about UV Ray exposure.

I use it for both, it does not contain sunscreen and the directions say to apply day or night after cleansing

No, actually another product that I bought on Amazon worked to clear the dark age-spots. Check my other reviews.

I'm not a molecular scientist but i do believe the exposure to the uv light is extremely minimal.Need notworry about sunburn.

Hello, Thank you for your inquiry. Yes, this filter removes 99.99% of Chlorine.

SPF really only addresses UVB light, but UVA light is just as dangerous, so it's important to buy a sunscreen that performs well in both (WebMD has a short article explaining this - http://www.webmd.com/beauty/sun/high-spf-sunscreens-are-they-better). Also, I no longer buy the Burn Out product because they changed their formula to a very sticky paste that doesn't apply easily. I prefer Thinkbaby SPF 50+ sunscreen (http://www.amazon.com/gp/product/B004CDQ73K/). Good luck!

It looks like what you are asking about is the sun screen. It is a moisturizer, but I only apply it on skin exposed to the sun and use the non-sunscreen moisturizer on the rest of my body. SPF 30 is adequate for most UVA & UVB protection.

Yes, but you have to cover everything with a towel to block the UV light inside.

No. You are looking for wrong product. This one is not a sun screen. It eliminate or erase any mark from skin, even preexisting for long time.

I am not totally sure of that answer, I just figured it was like clothes, if its covering up you aren't getting the full impact of the UV light, just like when you are out in the sun, your clothes protect your body. I think its better than not using them at all.

Yes it's broad spectrum (protects against UVA & UVB rays). It notes protection against both in the product description as well.
