Experiment: Is the sun so dangerous for a mole?

In this article, we will clearly show how the sun affects moles

Everyone has heard about the dangers of ultraviolet radiation. And most importantly, everyone knows that excessive exposure to the sun can cause skin cancer. But, any person believes that " this will not affect me/ I also sunbathe a little/ with benefits/ for the production of vitamin D/ I have a vacation" and everything in that spirit.

Therefore, we decided to clearly show that even a short-term stay in direct sun without protective equipment causes harm, which can be noticed with the help of NOTA mole tracker.

To do this, we take a device, an application and choose a mole that is initially healthy. The location is the upper part of the abdomen, i.e. the mole is constantly hidden from the sun by clothing.

General data: Fitzpatrick phototype - II, i.e. the object's skin is light, the tan goes badly, there is a high risk of getting a sunburn. Next, we collect our things and go to take sun and river baths. At the time of the collection, the UV index application showed 6 points, i.e. you can stay in the open sun without protective equipment for no more than 50 minutes. It would seem that we will not do this, because the first desire is to be in the water, and only then in the sun. 

 1.5 hours have passed. We make a measurement of the mole.

As you can see, the NOTA noticed changes in the mole. And this is despite the fact that most of these one and a half hours the subject was in the water(the ratio is about 60 minutes in the water, 30 minutes in the sun). Additional symptoms include fever and a slight itching near the mole, which means getting a slight sunburn. We check the mole through the photo application.

Not concerning… And if there is really nothing suspicious outwardly, then the sensations say the opposite. 

What is the conclusion from all this: The bioimpedance method notices used by NOTA changes in the nevus even after a short stay in the sun without protection(sunscreen, clothing). Applications for detecting changes in moles using photos are ineffective. Including magnifying glasses, since they make only a good photo, but do not examine the composition of the mole. Do not neglect sun protection products, even if it seems to you that you will not burn in the sun. I wish you good health and take care of yourself and your skin! 

P.S. When measured a day later, when the itching and skin temperature passed, NOTA showed that everything was fine with the mole.

​How to examine moles at home: Review of the personal mole tracker NOTA

NOTA mole tracker (https://notamole.com) - this is another device for the study of moles and the diagnosis of skin cancer, which stands out in a special way among others. For example, a magnifying glass is not attached to the phone, but this is an independent device that uses bioimpedance technology for measurements, i.e. it literally penetrates the skin by 2 mm with a weak electrical pulse and measures the resistance of cells. 

Here I will make a digression: healthy and cancer cells have different resistance (impedance), which is recorded and transmitted to the application on the phone. Here the data is processed and the result is given - whether the mole is dangerous or not.

Bioimpedance can also be found in smart scales that determine body composition, as well as fitness trackers that count calories.

Yes, the device has a fairly high price - $300, but if you compare, for example, with an annual subscription to the SkinVision application, you get $25 versus $45 monthly. And at the same time, the application is installed only on one phone(not every device is suitable), takes up the lion's share of the device's memory and can be used by only one person. NOTA can measure the moles of all family members, and the application for it is free, supported by almost any device and takes up 50 MB of memory.

After several months of use, I can share my impressions, as well as tell you how quickly moles get injured while being unprotected in the open sun.

Filling and appearance

Let's start with the fact that NOTA is a small black gadget that looks like a thick handle with a button, on one side of which there are removable heads with 4 electrodes, on the other - a charging connector. The case material is a pleasant-to-touch plastic covered with soft-touch, which prevents the device from sliding in your hand when measuring a mole.

NOTA weighs a little more than 40 grams, takes up little space when carrying, so you can take it with you on long trips or business trips without fear of overweight.

The kit includes a replaceable head in an individual velvet bag, a USB charging cable(which, by the way, can be replaced by charging from an iPhone), alcohol wipes and a velvet case for storing the device itself.

Inside the device there is a board, the components of which are produced by the American company Texas Instruments.

The sensitive brass electrodes of the device's head, which record changes in the cells, are coated with gold to prevent corrosion and increase the service life. For convenience, the device has 2 heads - a large one for measuring flat or large moles and a small one for measuring nevi protruding above the surface of the skin.

Cost.

I propose to close this issue immediately. What you need to understand is that you are not buying another gadget, but the opportunity to detect cancer at an early stage and cure it. Even if you have insurance, getting an appointment with an oncoderatologist(especially in California) is still a quest, and your meeting can be scheduled in 4-5 months. You can use the services of applications that analyze moles using AI, but at the end of the review I will clearly show why this is pointless. And if you have more than 100 moles on your body, then using NOTA will pay for itself in the first month and will save you a lot of time and nerves, since you buy the device once and for a long time.

Maintenance and technical specifications

The NOTA is equipped with a 370 mAh lithium-ion battery, which is enough for an hour of active work, during which you can measure about 180 moles. If we talk about periodic use, then I charged the device only once in 3 months. Full charging via the USB type C connector takes 4 hours, so you can put the device on at night, and actively use it in the morning. One of the huge advantages is that if it is not possible to charge the device completely, and the mole needs to be measured here and now, then you can use the fast charging function: put NOTA to charge...
