are they going to lose there glow eventually?

I don't know. We've had them for 3 months now and the glow is still strong. Having them out in the light seems to do it. Only time will tell if they become weaker.

Most "glow-in-the-dark" products are made with Zinc Sulfide (short glow time) or Strontium Aluminate (longer glow time). Both of these compounds are phosphors that give off light after being charged. I would guess the "glow" in these bands is due to Zinc Sulfide since the glow time is around 5-10 min a "charge". To the best of my knowledge either one can be recharged indefinitely without suffering any loss of performance. The more intense the light used for charging, the brighter the initial glow. Hope this helps answer your question.

To be honest I think that when you first put it on and it does it's thing and makes bubbles and it's hot and working that that will be what you will have so from then on so no I don't think that it will disappear. What you often get are speckles or white particles inside but if it's like you say a lot of glue like substance then maybe you should exchange until you do get a nice one it's like a lottery with these things like my first one is clearer than my second lamp .All the best. They are nice once you get them going.

yes. I think they lose a little of their potency but they'll keep for several months.

Don't know, haven't tried it, but I doubt it; if they did glow in the dark it would say so on the package.

They are activated by snapping(bending) them. It's been awhile, but I seem to remember them glowing for well over an hour. It may have been several hours. I remember by morning they were no longer glowing.

Mine do. Keep them in bright light for a minute or two first, then carry them to a dark room or another dark setting. The interesting thing about these "alien eyeballs," as I call them, is that they hold their glowability noticeably longer when they are exposed to natural light rather than artificial! Go figure!

If they are given a good half hour charge before the lights are turned out, they glow for very long time. Upwards of an hour and a half to two hours.

I think they will eventually. So far, mine are working okay. Sometimes when I press it to my face the light won't come on and I have to fiddle with it and keep pressing, so that is bothersome. But overall, I recommend the product. When I use all three colors at night my skin looks better in the morning.

No, these will fade even in indirect light. I bought these and still have them, just ok. When i needed more furniture I spent the extra money and bought Sunbrella, that stuff is amazing.

I think it might depend on, not only how long they are exposed to sunlight, but also other environmental factors (humidity and bioregion). The manufacturer claims that UV protection is included in the manufacture of the product, but research that I did suggests that they will still begin to deteriorate in a matter of months. Ours were out in the open for most of an Oregon summer filled with moist dirt, and seem to be ok so far.

When off, the color is the vanilla as you see in the picture. When on, they glow and flicker. I don't think the batteries last very long in them.

They are black but depending on exposure to sunlight over time, it could fade a little bit.

I would think they would gradually, but I'm not a doctor. The reasons for the dark circles is still there, but the serum has taken that away. If you stop the serum then they could eventually return. I'd contact the seller with this question to be sure.

Once they go on the base they start glowing. The longer on the base the brighter it gets.

Haven't had mine long enough to know. I do not anticipate they will last any longer, and they definitely are not as bright. But they sure are pretty!!

In my opinion - no. They light they give off is not white light and not very bright. The light has a yellowage cast

I watched them glowing last night as the rain from hurricane Arthur poured down. I have had them outside non-stop for several months with no problem. I had some similar lights from I bought from LL Bean and I left them out for 3+ years, winter and summer.
