There are several reasons why gel nails change colour. One reason could be that the gel nail polish used was contaminated with a different colour. Another reason could be overexposure to UV light, which can also happen if you spend a lot of time in the sun or use self-tanners. Additionally, certain gel nail polishes are designed to change colour under certain conditions, such as thermal gels that change colour according to temperature or mood-changing nail polishes. The high acid content in certain foods can also interact with gel nail paint, causing it to change colour.

What You'll Learn
Exposure to UV light
UVA radiation has been linked to several skin concerns, including premature aging, wrinkles, dark spots, thinning of the skin, and loss of elasticity. The skin on the hands is thinner than on other body parts, making it more sensitive to UV light and accelerating aging. To protect your hands and nails from UVA radiation, it is recommended to apply sunscreen with at least SPF 30 or wear ultraviolet protection factor gloves before your appointment.
In addition to the health concerns, improper curing under UV light can also affect the durability and longevity of gel nails. Under curing is a common issue, leading to skin irritation and allergies. It can also cause premature chipping, peeling, or even complete detachment of the gel from the natural nail. To ensure proper curing, it is important to apply thin layers of gel nail polish and use the correct UV nail lamp according to the manufacturer's instructions.
While UV light exposure during gel nail manicures can have potential health and cosmetic impacts, taking precautions such as limiting the frequency of manicures, using sunscreen or gloves, and ensuring proper curing techniques can help mitigate these risks.

Chemical reactions
The phenomenon of colour change in gel nail polish can be attributed to various factors, including chemical reactions. One notable instance involves the interaction between the nail polish and certain substances used in cosmetics or cleaning agents. This was evident in an account where a person's gel nail polish changed colour on one hand, which a licensed cosmetologist attributed to a potential chemical reaction from cosmetics or cleaning agents.
Thermochromic pigments, which are sensitive to temperature variations, play a significant role in the colour-changing properties of gel nail polish. These pigments undergo structural changes when exposed to different temperatures, resulting in a transformation of colour. The molecules in these pigments have two forms: one that absorbs light and appears coloured, and another that reflects light and appears transparent or differently coloured. As the temperature increases, the molecules rearrange, causing the pigment to transition to its alternative form, thereby altering the way light interacts with it and producing a new colour.
Additionally, overexposure to UV light can also lead to discolouration of gel nail polish. This can occur through prolonged sun exposure or the use of self-tanners, resulting in varied discolouration across individuals. Smoking can also cause yellowing of the nails, particularly on the dominant hand, as the hand holding the cigarette experiences more direct contact with the smoke.
In some cases, the application process itself can influence the colour stability of gel nail polish. Applying the polish too thinly can lead to fading, while applying it too thickly can result in lifting, chipping, or improper curing. The choice of top coat is crucial, as some products, like the Express5 top coat, may not provide sufficient protection, especially in extreme summer conditions.
Furthermore, certain foods and cooking ingredients can interact with gel nail polish, leading to discolouration. This is particularly true for ingredients with high acid content, such as tamarind, or staining agents like turmeric. It is advisable to minimise direct contact with intensely coloured or staining foods to maintain the desired nail polish colour.

Thermochromic pigments
The thermochromic powders come in a variety of colours and temperature sensitivities. For example, some powders react to heat at 86 degrees Fahrenheit, while others are heat-sensitive at 77 degrees or cold-sensitive at 72 degrees and cooler. This allows for a lot of creativity in designing nail polish that changes colour at specific temperatures.
When creating your own thermochromic nail polish, it is important to note that compounds with strong acidic or alkaline properties should be avoided as they can be harmful. Additionally, the removal of thermochromic nail polish may require some extra effort, as regular acetone removers may not be effective, especially for gel nails.
Thermochromic nail polishes are available commercially as well, offering an easy way to achieve this unique look without the DIY mixing. These polishes provide intense pigmentation and a matte finish. To enhance the glossiness of the manicure, a top coat can be applied.
The thermochromic pigments in nail polish allow for a fun and creative way to play with colour and temperature. Whether you make your own polish or purchase a ready-made one, the colour-changing effect is sure to be a conversation starter!

Intense colours in food
Gel nail polish manicures can change colour due to several reasons. One possible reason is a chemical reaction from cosmetics or cleaning agents. Another reason could be the use of hand sanitiser, sunscreen, or washing dishes without gloves, as these products can cause the gel polish to degrade or change colour. In some cases, it may be due to the UV lamp used during the curing process, which can cause the colour to fade or change.
Now, let's shift our focus to the topic of intense colours in food. Colour is a powerful tool that can deeply impact our perception of food and even influence our taste buds. It can make us perceive sweetness that isn't there and experience flavours that aren't present. Food manufacturers understand the importance of colour in shaping consumer expectations and creating appealing products.
Research has shown that people tend to associate the intensity of colour with the intensity of flavour. For example, a bright red apple is expected to taste sweeter than a dull red one. This association between colour and flavour intensity has been demonstrated in various studies, including those by Clydesdale et al., who found that adding food colouring could increase the perceived sweetness by up to 10%.
The impact of colour on taste perception is so strong that it can even override our other senses. This phenomenon was highlighted in a study where participants evaluated the flavour of cakes under different lighting conditions. The results showed that the brighter the cake was, the more intense the flavour was reported to be, even overriding the actual flavour levels.
Additionally, colour can also affect our willingness to try certain foods. For example, in the case of Mr. I, a painter who lost his ability to perceive colours, any food that didn't match his memories became unappealing. He ended up sticking to a black-and-white diet, where the colour of the food matched his expectations.
In conclusion, colour plays a crucial role in shaping our perception of food and can deeply impact our sensory experiences. Food manufacturers can use this knowledge to create products that meet consumer expectations and enhance their eating experiences.

Hand sanitiser
To reduce the impact of hand sanitiser on gel nails, it is recommended to:
- Wipe away any excess hand sanitiser from the nails after application.
- Use cuticle oil or balm after every hand wash to protect and hydrate the nail coating.
- Wear gloves when using detergents and cleaning products at home to create a barrier between the nails and chemicals.
- Avoid opening packages, letters, cans, and cartons with gel nails, as this can also damage the manicure.
It is also worth noting that increased handwashing can contribute to manicures chipping, lifting, and peeling. Therefore, it is essential to keep nails moisturised and hydrated to maintain their flexibility.
