Mood gel nail polishes are thermochromic, temperature-sensitive compounds that change colour when exposed to heat or cold. The polishes usually come in dual-tone shades, and the colour change is activated by body heat, ice, or hot water. There are many brands that offer mood gel nail polishes, such as DND, AIMEILI, and Mia Secret Nails.

Mood-changing nail polish: does it work?
Mood-changing nail polish is a type of nail polish that is supposed to change colour in response to changes in body temperature. It is also known as thermochromic nail polish, which means it is made using a temperature-sensitive compound. The polish is supposed to change colour with exposure to heat.
There are many brands that sell mood-changing nail polishes, such as DND, AIMEILI, iZZZHH, Penkiiy, and Mia Secret Nails. These polishes are often marketed as "chameleon" polishes, with colours ranging from pink, purple, and blue to green, orange, and red.
However, the effectiveness of these polishes has been called into question. In an experiment conducted by Refinery29, a journalist tried out a mood-changing nail polish to see if it worked. Despite several attempts to elicit a colour change, including surprises that were expected to induce excitement or emotion, the polish did not change colour.
While mood-changing nail polishes may not be completely reliable in terms of colour-changing properties, they can still offer a fun and unique manicure experience for those who enjoy experimenting with nail art and trying out new trends.

The science behind thermochromic technology
Mood gel nail polishes are thermochromic, meaning they are made of temperature-sensitive compounds that change colour with exposure to heat. The polishes are designed to respond to body heat, ice, or hot water, causing the colour to shift. This technology is not new, but its effectiveness is questionable, as evidenced by an experiment conducted by Refinery29. In this experiment, the polish failed to change colour in response to several mood-changing surprises, including a giant pizza and an unexpected visit from a friend. However, when the individual using the polish later entered a hot and sticky subway, they noticed that their nail colour had changed.
The thermochromic technology used in mood gel nail polishes relies on liquid crystals that reflect light at different wavelengths as the temperature changes. These liquid crystals are composed of rod-like molecules that are embedded in a flexible organic structure. As the temperature increases, the molecules move closer together, altering the spacing between them and, consequently, the wavelength of light they reflect. This change in light reflection results in a visible colour shift.
The specific chemicals used in thermochromic technology vary, but they typically involve leuco dyes, which are colourless or white at a certain temperature and become coloured when the temperature changes. These dyes are often used in combination with other chemicals, such as fluorans, that can change the dye's ability to accept or donate electrons, resulting in a colour shift. Another common ingredient is a solvent, which helps to dissolve the thermochromic pigment and allows it to be applied as a polish.
The effectiveness of mood gel nail polishes may depend on individual body temperature and the surrounding environmental conditions. Additionally, the colour-changing properties of the polish may be influenced by the number of coats applied and the length of time it has been worn. While the technology is intriguing, the sensitivity of the polish to subtle temperature changes suggests that it may not be a reliable indicator of mood.
Despite the questionable effectiveness of mood-changing nail polish, the technology has a wide range of applications beyond cosmetics. Thermochromic technology is used in various industries, including medicine, where it is employed in temperature-sensitive labels and indicators for pharmaceuticals and medical devices. It is also utilised in the food industry to create colour-changing packaging that indicates when a product is at the perfect temperature for consumption. Additionally, thermochromic materials are used in textiles and clothing to create fabrics that change colour with body temperature, providing a unique aesthetic appeal.

Gel polish: LED and UV options
When choosing between an LED and a UV nail lamp for gel nail polish, there are several factors to consider, including budget, time, and the type of gel polish you want to use. LED lamps are generally more expensive than UV lamps, but they cure gel nails more quickly and last longer without needing to replace the bulbs. LED lamps emit narrower UV wavelengths with higher concentrations and more energy, which target specific photoinitiators in the gel polish, enabling faster curing. This makes them a good choice for those who are short on time.
However, it is important to note that not all gel polishes can be cured by LED lamps. Salons that use strong gels, such as UV gel or hard gels, typically rely on UV lamps, which cure all types of gels. UV lamps are also more effective for curing clear gel nails. While LED lamps may be more convenient in terms of curing time, UV lamps have their advantages in terms of versatility and cost.
Both LED and UV nail lamps can be used for at-home gel manicures, with kits available that include the lamp, gel polishes, nail files, cuticle sticks, and other accessories. These kits offer a cost-effective and convenient way to achieve salon-worthy nails in the comfort of your own home.
Gel nail polish, including mood-changing gel polish, can be cured using either LED or UV lamps, depending on the specific product and its instructions. Mood-changing gel nail polish works by using thermochromic compounds that react to temperature changes, causing the polish to shift between different colours. This can be activated by body heat, ice, or hot water, creating a fun and dynamic nail look.

DIY salon manicures at home
DIY salon manicures can be done at home with a few simple tools and products. The process is simple and can be achieved with practice and patience. Firstly, it is important to source the right products. Gel nail polishes are a great option for a long-lasting manicure, and there are many options available, including mood-changing gel polishes that react to temperature changes. These polishes can be purchased as part of a kit or individually.
To begin your manicure, ensure your nails are prepped. Start by cutting your nails to your desired length, then use a nail file to smooth out any rough edges. A glass nail file is a great option for achieving a smooth finish. Next, use a cuticle remover and cutter to gently push back your cuticles. You can also apply cuticle oil to soften them before pushing them back. Remember to wash your hands after this step and swipe your nails with acetone to remove any excess oil.
Now you are ready to start painting! Pick your desired colour and start applying thin coats of polish to your nails, being careful not to get any on your cuticles. Cure each layer under a UV lamp for about 2 minutes, and repeat this process until you have achieved your desired opacity. Some lighter polishes may require an extra coat. Finally, apply a gel top coat and cure it under the lamp one last time. You can also add a few drops of cuticle oil to hydrate your nails.
To remove your gel manicure, do not peel it off as this can damage your nails. Instead, use nail polish soak-off clips and cotton pads soaked in acetone to safely take off the polish. With these simple steps, you can achieve salon-worthy manicures at home and save time and money!

Testing mood-changing polishes
Mood-changing nail polishes are claimed to be activated by body heat, ice, or hot water, which changes the colour of the polish. However, some users have reported that these polishes do not work. To test the efficacy of mood-changing nail polishes, one could try the following:
- Place your hands in hot water for an extended period, ensuring that the water is at a temperature that is safe for your skin. Observe if the nail polish changes colour.
- Hold ice in your hands for a few minutes, and again, check if the nail polish colour changes.
- Expose your nails to your body heat by cupping your hands over your mouth and nose, breathing deeply for a few minutes. Observe any changes.
- Try using a hairdryer on a low heat setting to blow warm air onto your nails.
- If the polish includes glitter, observe whether the glitter particles change colour when exposed to different temperatures.
It is important to note that the success of these tests may vary depending on the brand and type of mood-changing polish used, as well as individual body temperature and external factors such as ambient temperature and humidity. For accurate results, it is recommended to test the polish in a controlled environment and compare the results with others who have conducted similar experiments.
