Does the effectiveness of this sunscreen wear off after a certain length of time (2 hs.) or is it about the amount of sun exposure this product can deflect?

You should definitely reapply every 2 hours, more frequently if you are wet/sweating/toweling off. The tube says it will last for 80 minutes.

It means that after it's applied and exposed to sunlight it will remain effective for 14 days.

That's difficult to say. The box states "skin is moisturized 24 hours and receives protection from UVA rays." I would guess that the duration of protection depends upon the degree of sweating and exposure to water. I only apply it in the morning but I don't go swimming or sweat that much.

In my case, I had some dark spots on my face especially. The spots r from sun damage in my case. After using this product for some time now, my spots r barely noticeable anymore. I will be 65 in a couple of months too, & I highly recommend this product!

I've been putting it on my face for months... no problem. It's thick & white though... so don't expect it to go on clear. This the REAL DEAL sunscreen. I'm an avid fisherman.

I have used this on myself with good results while swimming or sweating. I am moderately fair skinned, and I often get a bit of a tan following prolonged exposure while wearing sunblock, which is normal for me and I don't mind. I think that did happen a little with this, but I didn't find that unique to this product, and it also could be partially due to my own failure to reapply per the directions, as I often go longer than the labels recommend before reapplying. The same company also has a "thinksport" product, which I have not tried, but sounds like it is specifically for sweating. I have used this on myself with good results while swimming or sweating.

I have been using this product for 2 yrs with GREAT results. Recommended by Dr Oz on his show. I put it all over my face, eye lids and neck 2ce each day - morning after shower and evening just before bed. If I stop using for just 2 days, I start to see the return of deepened wrinkles. Go back to using and wrinkles fade substantially. I am a product junkie and end up throwing most of them away or returning for lack of results. I keep buying this one. Hope this helps

Probably not. It stays on a while and seems to have staying power, but no sunscreens are allowed to market themselves as "waterproof" anymore because they all need to be regularly reapplied.

Hi! My own experience: bought the duck 2 days ago. I have a screen-enclosed pool like you do. Exposed the animal 5-6 hours in full light/sun exposure yesterday. The LED light turned on at dusk, as expected. Very nice. Am ordering a second unit today! I really don't see why the screen would prevent the sun to activate the solar cells, it does not prevent my wife to get a beautiful suntan... Nothing to do with the screen, provided you have direct sunlight. Unless you have big trees or some other reason preventing the sun to go through. Enjoy it, or return it to Amazon, if you're not happy! Hi! My own experience: bought the duck 2 days ago. I have a screen-enclosed pool like you do.

Each time I apply it I usually reapply in 3 hours.... That's just a rule of thumb for all sunscreen. My family of 4 has used it since May with a week at Lake Powell in the middle of summer and there is about 1/8 left... I will reorder for Spring Break but the current one will last through the Christmas ski vacation.

It does not say on the bottle and what I have noticed when using is that it does come off in water. It does do a good job of protecting from the daily sun and I do like this product, but I feel like I have to double up with a water resistant sunscreen if I'm going in the pool.

I've only been taking it for about 3 weeks and haven't noticed any difference. Some have seen faster results but realistically, I don't expect to see a difference for 2-3 months. Wrinkles and stretch marks didn't happen overnight so can't expect them to diminish overnight either.

I use this daily, so my best guess is that it still works with moisturizer and makeup. Its no problem putting it on after your moisturizer, but I don't apply makeup over it myself so I can't say for sure. The sunscreen definitely works great, if anything it works so well that it can make the skin close to my eyes extra sensitive to sun when I don't wear it. I hope that helped, I thought I'd go ahead and respond because I'm grateful to everyone who answers my questions.

There should be an expiratio date on the sun shield matte tube. it usually is good for six months.

You'll just need to reapply more often. SPF measures how long it will take for you to sunburn.

I use it all over my face and my kids faces. Because it is so easy to spread it is very easy to get close to the eye without getting any in their eyes. Again because it is so easy to spread (not sticky at all, feels like spreading powder) you can use far less then other sunscreens and still get good coverage, mine tubes last a long time. If we are at the beach or pool I reapply every couple of hours, same as any sunscreen. I have found it to be very easy to use and very effective.

I believe the label says it is good for 2 hours unless worn off from perspiration or swimming, then apply more frequently. I use it for my daughter and me, and it works very well.
