Sweat Sodium Testing
The MX3 Hydration Testing System uses a single device to run two different tests in real-time that tell you how much fluid to drink and what kind of fluid will best replace the electrolytes you lose during exercise.
The sweat test measures sodium levels, so you can replace lost electrolytes and customize your hydration strategy with the right fluids. With MX3, you can test, track and hydrate effectively to optimize your performance and reduce injury.

Color: Pink
Great product! It’s very easy to use and gentle on the skin. The ceramic blades work smoothly without causing irritation or cuts. I love the sleek design, the LED display to check the battery level, and the Type-C charging. It comes with useful attachments and the battery lasts a long time. Perfect for the bikini area and other sensitive zones. Highly recommended!

Fades stubborn dark spots fast
I have used this product for about six months to target dark and red spots left behind after my zits clear up. I was honestly surprised at how much it helped fade stubborn discoloration, even after just one use.
Pros
-Noticeable reduction in discoloration after one use
-More effective for small spots than typical serums
-Targets persistent dark/red marks specifically
Cons
-Effects can fade if not used regularly
Overall, this has become my go-to for spot treatment because it works quickly and is more targeted than a general serum. I especially appreciate how it faded a stubborn old mark in just one application. A five star rating feels appropriate because it delivers visible results on stubborn discoloration, though consistency is needed to maintain the effect.

Buy them!
Ok I was a little hesitant based off these reviews but I decided to try them anyways. OMG I am a chronic face picker and cause sooo much scarring. And I always do it right before summer which causes horrible dark spots that take years to fade. Well I had one that was in a particularly noticeable spot and omg after only 3 days…3 it looks so much better with these patches!!! Don’t get me wrong it isn’t gone but for 3 days that is unreal. I will be using until it’s gone for sure!

Subtle but works!!
Okay there are PRICEY for the small amount you receive. I believe they work for sure and will buy them again but which they would put a FEW MORE in a pack because they are not like miracle patched and you definitely need two packs to see a significant difference.

Did nothing for hyperpigmentation, worked well on active blemish
I use these for an active blemish and they work well for reducing inflammation and redness. They are marketed for hyperpigmentation, but they didn’t seem to have much of an effect on lingering redness from an old breakout after a few uses so I decided to use them on a whitehead that popped up on my chin. I bought two packages and had passed the return window so I figured couldn’t hurt. After a few hours with this patch on, the whitehead and surrounding redness virtually disappeared. They are almost invisible on the skin IF you can remove them from their clamshell packaging without scrunching up and wrinkling the edge of patch. BIG IF!!! Most of the time I mess up the edge of the patch making the wrinkled edge visible on my face. I wear them around the house so I don’t really care about that, but it’s worth mentioning. You have to remove them from the packaging VERY carefully to keep the patch smooth. I’ve been mostly unsuccessful at removing them without scrunching up an edge. Oh well.
Peach Slices makes a similar product for acne, “deep blemish microdarts”. I haven’t tried those, nor do I plan to because the amount of product that you get for either kind of micro dart is not a good value to me. I wish these were less expensive. I do like the way the micro dart feels when you apply it- kind of a satisfying stinging sensation- like the ingredients are really penetrating. I would not call it painful. A moment of sting and it’s on there doing it’s job. It stays on well while doing basic daily activities (like doing the dishes, working at a desk). Can’t say how it would hold up to something more vigorous like a jog or bike ride or anything that would make you break a sweat. I like the product and the result on blemishes, but I can’t justify the cost. A warm compress and followed by a vitamin C serum on a blemish works just as well and it’s way more cost effective, albeit less convenient.
Also, the ingredients in the product description are incomplete. See photo- they contain Butylene Glycol which is sometimes irritating to my skin. Luckily, these patches didn’t irritate me. Having to 3rd party check the ingredients for cosmetics from Amazon irritates me though 😒
If these are affordable for you for the occasional blemish, I would recommend. Did nothing for hyperpigmentation and way too expensive for me to combat a full breakout or even a daily random pimple. I’ll use the ones I have but would not purchase again.
