There are several reasons why gel nails might change colour. One reason could be that the person has used a mood-changing or temperature-changing nail polish, which alters colour in response to shifts in temperature. Additionally, certain substances, such as sunscreen or highly acidic fruits, can cause gel nail polish to change colour or fade. In some cases, the UV lamp used to cure gel nails may also cause the colour to change or fade.

What You'll Learn
UV lamps used to cure gel nails can cause colour changes
Gel nail polishes contain a chemical called photoinitiators, which require direct UV wavelengths to harden or cure. The two types of nail lamps used to cure gel nail polishes are LED and UV lamps. Both of these emit UV radiation, predominantly in the form of UVA rays, which have been linked to premature skin ageing and skin cancer.
UV lamps take longer to cure nail polishes compared to LED lamps. Typically, an LED lamp will cure a layer of gel polish in 30 seconds, while it takes a 36W UV lamp 2 minutes to do the same. However, some gel polishes have been formulated to be used with UV nail lamps only, so an LED lamp will not work. All gel polishes are compatible with UV lamps as they emit a wider spectrum of wavelengths that can cure all types of gel polishes.
The UV exposure from these lamps may cause colour changes in gel nails. A user on Reddit reported that their gel nail polish changed colour overnight, and a possible reason for this could be the UV lamp used to cure the gel. Another user on lohud.com also reported a similar incident, where their gel nail polish manicure changed colour on one hand. The user contacted Revlon, the parent company that owned the nail polish brand, and a licensed cosmetologist at Revlon suggested that it could have been a chemical reaction from cosmetics or a cleaning agent.
To reduce the risk of skin cancer, it is recommended to apply a broad-spectrum (UVA/UVB) sunscreen to hands before exposure to UV light.

Colour-changing gel nail polishes react to temperature changes
Gel nail polishes that change colour based on temperature changes do exist. These nail polishes contain special pigments that react to temperature changes. When your hands are cold, the polish shows one colour, and as your hands warm up, the pigments change, and the polish shifts to a different colour. This can be influenced by your body temperature or the temperature of the elements around you. For example, if you are wearing a purple and seafoam green colour-changing polish, your nails will appear more purple when cold and more seafoam green when warm.
The colour-changing effect can also create a two-toned or ombre effect. For instance, a pale pink when warm and fuchsia when cold. The length of your nails can also influence the colour-changing effect. Longer nails can result in a more pronounced colour difference between the warm nail bed and the cooler tip.
Some brands that offer colour-changing gel nail polishes include LUXA, Bio Seaweed Gel, and Femme Fatale. It is important to note that these nail polishes are sensitive to temperature changes, so you may want to experiment with hot and cold water or air to observe the colour transformations.

Acidic fruit can interact with gel nail paint
Gel nail polish is painted on and then cured under a UV lamp, which dries and hardens the polish almost instantly. The curing process involves photopolymerization, where a liquid absorbs energy from UV or visible light and undergoes cross-linking to become a solid. While gel nail polish is generally considered safe for nail health when used sparingly, it does contain chemicals that can react with other substances.
One such substance is fruit with a high acid content. In a personal account, a reporter describes how their gel nail manicure changed colour after cooking with tamarind extract. They concluded that the high acid content in the fruit was interacting with their gel nail paint, causing it to change colour.
This phenomenon is not limited to tamarind; other acidic fruits such as tomatoes, lemons, or oranges could potentially have similar effects. It is important to note that the interaction between acidic fruit and gel nail paint may not always result in a colour change but could still impact the nail polish's appearance or durability.
Additionally, other factors can cause gel nail polish to change colour. One suggestion is a chemical reaction from cosmetics or cleaning agents. For example, sunscreen has been known to cause gel nail polish to fade or change colour. The UV lamp used to cure gel nail polish can also cause the colour to change or fade after a few days, especially if dip powders are used with the gel liquids.

Mood-changing nail polishes alter colour with a shift in temperature
Gel nail polishes can change colour due to various reasons, including exposure to sunlight or certain chemicals. However, there are also mood-changing nail polishes that are specifically designed to alter colour in response to temperature changes. These nail polishes contain special pigments that react to heat, resulting in a dynamic and mesmerizing colour-shifting effect.
For example, the LUXA Color Shift collection offers a range of gel polishes that change colour based on temperature fluctuations. Users can experience a subtle shift from soft pink to lavender or a dramatic transformation like green to blue. Similarly, the RARJSM Temperature colour-changing gel nail polish collection features a magical pearl shell design that displays different colours when the temperature exceeds 28°C or falls below 18°C.
The colour-changing mechanism in these nail polishes is influenced by both body temperature and environmental temperature. As your body temperature changes, the pigments in the polish respond, resulting in a shift from one colour to another. This effect can be enhanced by applying the polish to longer nails, as the greater temperature difference between the warm nail bed and the cooler tip creates a more pronounced colour contrast.
To ensure optimal performance of mood-changing nail polishes, it is recommended to stir the polish before application to evenly distribute the colour-changing pigments. Additionally, proper nail preparation, such as cleaning, buffing, and applying a base coat, is essential for a smooth finish. Sealing the colour-changing polish with a top coat can also help extend its longevity and protect it from chipping.
While mood-changing nail polishes offer a fun and unique way to express yourself, it's important to note that they may not be suitable for everyone. Some individuals may prefer traditional gel polishes that maintain a consistent colour. Nonetheless, for those seeking a dynamic and interactive manicure experience, mood-changing nail polishes that alter colour with temperature shifts provide an intriguing and captivating option.

Old nail polish can cause colour changes
There are several other reasons why gel nail polish may change colour. One reason could be the use of a mood-changing nail polish that alters colour with shifts in temperature. Another reason could be exposure to sunlight, as some polishes are designed to change colour under UV light. Additionally, certain foods and spices, such as highly acidic foods or staining spices like turmeric, can interact with gel nail paint and cause discolouration.
To prevent discolouration, it is recommended to change nail polish every three weeks and choose a reputable nail salon. However, there is no guaranteed way to prevent gel polish discolouration.
If discolouration occurs, there are a few methods to restore the original colour. For mild to moderate discolouration, a non-acetone nail polish remover or rubbing alcohol can be used to gently wipe the affected area. This method is most effective soon after the discolouration appears. For more severe discolouration, tea tree oil can be added to warm water, and nails can be soaked for about 10 minutes. This process can be repeated once a day until the original colour returns.
