Compact UV Mirror with UV Camera for Sunscreen Test, 4 Inch Rechargable Travel Mirror Handheld Double-Sided Pocket Mirror for Skin Protection

Love this. High resolution, turns off and on when you flip it open, and really helps with sunscreen. Cellphone shaped. Great value

Bought it and realized that my sunscreen from china was just a moisturizing cream. Would be awesome if it had an option of taking screenshots.

The media could not be loaded. See video - THIS PRODUCT EXPOSES YOU TO UV LIGHT. The light that this camera uses to see if your sunscreen is working, is a UV LED - it produces UV light as tested and confirmed with the included UV card. So irresponsible for the seller not to disclose this, as most people are using this to confirm their sunscreen works to protect against UV. The fact that this produces UV is so counterintuitive and dangerous for people not to know. I'm giving it 2 stars because it does work to verify your sunscreen, but you're risking skin damage just by using it. Highly do not recommend.

This is a cool idea, although for me it wasn't useful..I make my own sunscreen with zinc oxide so I really wanted to see if it was working.UVB rays are necessary to absorb synthetic vitamin D so if this does indeed give you UVB and not UVA, this would be really helpful for me. Just need to find a way to test it to make sure!Thought it was expensive considering you can see if you're tanning after about eight minutes but I understand if other people don't want to take that risk.

UPDATE: Just because I wanted to make sure, I tested that this product appears to be using UVB LEDs for the lighting to detect the sunscreen which is correct as UVB/UVC blocking is critical for good sunscreen performance and UVC is a bit too damaging for you to purposefully expose yourself to it regularly. I did this through one of those UV test cards with both UV and UVC sections, for which it caused the UV section to turn purple (same indicator as the test card they include) but the UVC section did not glow (which it does in sunlight). I then tested the device's sensitivity to UVA light with a separate UVA flashlight and it barely registered the extra light (while the UVA also caused the UV indicator to change color). So by process of elimination the device's LEDs should be somewhere in the UVB range.Original review is as follows:----------------------------------------------------------Glad I found devices like this exist as on first use I realized I was not getting very good coverage on applying sunscreen around my eyes and mouth. Especially with a chemical based sunscreen it basically looks like you're applying black paint to your face. As the product description mentions though, there are some caveats that may make it not work as well for you personally. Basically the UV camera just picks up on the difference in UV reflectivity between your skin and any products you apply. So chemical based sunscreens absorb UV and appear black while mineral/physical sunscreens (e.g. titanium and zinc oxide based) reflect UV and appear "white" (actually lighter gray on the screen). But then the melanin that makes people have darker complexions also absorbs UV. Especially with how dim the integrated UV LEDs are (for safety) I can see people having issues distinguishing between the UV reflectivity characteristics of the sunscreen versus their skin if the values are on the same side of the spectrum. You may be able to improve things by viewing it outside in sunlight (full UV from the sun is much more intense than that provided by the LEDs. Obviously limit your exposure in that case) or by using the opposing type of sunscreen (chemical sunscreens for lighter complexions, mineral/physical sunscreens for darker complexions).Kind of wish they included a second wider angle camera which would make it easier to use this for applying sunscreen to your body. The field of view of the camera is mostly useful for viewing your face. I can see why they might've chosen that field of view as the integrated LEDs are only bright enough for viewing at a short distance, but a wider angle would've been useful when you were in sunlight and not relying on the LEDs for illumination. Also the hinge would've been useful to either have multiple detents or just be stickier along its travel so you can use the lid/mirror portion as a stand. I still end up standing it on its lid, but it only seems barely stable at a right angle and I'm still worried a slight movement would make it either snap shut or open fully and possibly make it fall off the counter. Having it stand on its own allowing for a hands free option would've been nice when your hands might both be covered in sunscreen.

Disclaimer: Product descriptions typically provide information about what products claim to do, so I like to focus my reviews more on the negative aspects of products to make other people aware of issues or concerns before purchasing. My reviews are based on specific tests that I conduct, so others may not experience the same results or share the same opinion.Overview:My wife always reminds me to wear SPF, so when I saw this product I thought this not only would encourage me to wear SPF, but also know if I'm applying it for full coverage. My wife and I like to travel during the summer, so this seems like a practical thing to own and bring with us to make sure we have the proper sunscreen coverage during our trips.Negative(s):-Not great for dark skin-No charging brickConclusion:I never knew this kind of product existed. It comes with a UV card that you can test against the sun to see what level of SPF you need. Honestly, using the highest SPF you can is always the best bet. When using the UV camera part, I found it easier to use it upside down because of the location of the camera (bottom). It doesn't affect anything, and easier to see your face. I also found you can use the mirror part as a stand. I'm a little on the darker side (butterscotch), so it is a little more difficult to see the SPF being applied on my face, but I know it works because on my hands, I can see the SPF more clearly. That's my main con about this as it works, just not that great to see on darker skin. It uses USB-C to charge, so it's convenient for me since most of my electronics also use USB-C cables. Like most products these days, there's no charging brick included, but not a deal breaker.Do any of the negative(s) affect my overall rating and/or recommendation?Yes, but not really. I knocked off 1 star because it is hard to see the SPF applied to dark skin. I can still see it on mine, but if you're darker than butterscotch, then it might not work. Knowing that, I would still recommend this product to anyone lighter than me.
