Gel nail polish is a popular choice for those wanting a long-lasting manicure. However, over time, gel nail polish can start to fade or change colour. This is due to the chemical structure of the colourant ingredient slowly changing when exposed to UV light. This can be from sunbeds, natural sunlight, chlorine, and even computer screens. To prevent this, it is recommended to apply a clear nail polish over the gel polish or use a top coat to protect the colour. Other ways to prevent fading include drying nails after swimming and avoiding exposure to chemicals such as insect repellent and hair dye.

What You'll Learn
The impact of UV exposure
UV light is a type of radiation that is invisible to the human eye but can be felt as energy. When UV rays collide with certain chemical bonds, they act like a pair of scissors cutting a thread, permanently altering the chemical structure. This is why materials like newspaper turn yellow when left in the sun, and it is also why cosmetic colorants, including gel nail polish, fade over time.
To minimise the impact of UV exposure when using gel nail polish, it is recommended to take several precautions. Firstly, using non-UV gel polish or opting for regular polish with a quick-dry top coat can eliminate the need for UV exposure altogether. If using gel polish, it is important to follow the recommended curing times and not overexpose the nails to UV light. Applying a clear nail polish over the gel polish can also help protect the colour from fading due to UV exposure. Additionally, it is advisable to protect the hands and nails from excess sunlight exposure when outdoors, as natural sunlight contains UV energy that can contribute to discolouration and fading.

The role of chemicals and solvents
Additionally, certain chemicals and solvents can directly impact the colour and durability of gel nail polish. Solvents like insect repellent and suntan lotions often contain DEET, which can dissolve and affect nail products. This can lead to discolouration and staining. To prevent this, it is recommended to wipe nails or wash hands immediately after applying these products. Applying a clear nail polish over the gel polish can also act as a protective barrier.
The type of pigments used in gel nail polish also plays a role in fading. Some pigments, especially pinks and corals, are more prone to fading due to their chemical structure and sensitivity to UV exposure. This is why it is common to experience gel nail polish fading during the summer, as certain colours react to sunlight and summer activities.
Furthermore, the application process of gel nail polish can influence its susceptibility to fading. If the layers are applied too thinly, the colour may fade, and the polish may not last as long. On the other hand, applying the layers too thickly can lead to chipping and improper curing. It is crucial to achieve the right balance in layer thickness for optimal results.
While gel nail polish provides a durable and long-lasting manicure, it is not immune to the effects of chemicals and solvents. Understanding the role of these factors in fading can help nail technicians and individuals take the necessary precautions to maintain the colour and integrity of their gel nail polish.

Preventing fading with a top coat
Applying a top coat is a great way to prevent gel nail polish from fading. A top coat acts as a protective barrier, shielding your nail polish from external factors such as water, chemicals, and everyday wear and tear. It helps prevent chipping, peeling, and fading, ensuring your manicure lasts longer.
There are several types of top coats available, each with its own unique benefits. Here are some options to consider:
- Clear Top Coat: This type of top coat provides a glossy finish and enhances the colour and shine of the underlying nail polish. It is transparent and can be used with various types of nail polish, including gel polish.
- Matte Top Coat: This top coat gives a matte or non-shiny finish to the nails, creating a trendy and modern look.
- Gel Top Coat: Specifically designed to be used with gel nail polishes, gel top coats add shine and gloss while protecting the nails.
- Quick-Dry Top Coat: Quick-dry top coats allow you to apply multiple layers of polish in a shorter amount of time, which is convenient when you are in a hurry.
- Strengthening Top Coat: Strengthening top coats are formulated with ingredients that help to strengthen and protect the nails, reducing breakage and promoting healthier nails. They can also add shine and gloss to your manicure.
- UV-Protective Top Coat: If you are concerned about UV exposure causing discolouration or fading, consider using a UV-protective top coat. These top coats are designed to shield your nails from harmful UV rays, preventing yellowing and discolouration.
- Peel-Off Top Coat: For those who like to change their nail colour frequently, a peel-off top coat is a convenient option. It creates a temporary layer that can be easily removed without the need for nail polish remover.
When applying a top coat to prevent gel nail polish from fading, it is important to ensure that your nails are clean, dry, and free of any lotions or oils before application. Additionally, make sure that each layer of polish is completely dry before applying the next coat. For best results, you can also try painting the edges of your nails with both the nail polish and the top coat to seal in the colour and create a longer-lasting manicure.

The removal process for gel nail polish
Gel nail polishes are formulated with acetone-soluble polymers, which is why they can be removed in about 5-10 minutes. However, the longer the gel polish is worn, the longer it takes to remove. Over-cured gel polish is more difficult to remove and can lead to nail damage such as surface white spots. This is because the harder the product is, the more force is required to scrape it off.
To remove gel nail polish, you will need acetone, cotton balls or pads, and foil wrap or nail soak-off caps. Start by filing the gel polish to break the top coat. This helps the acetone penetrate the polish more effectively. Next, soak the cotton balls or pads in acetone and place them on your nails. If you are using foil wrap, wrap each nail individually to hold the cotton in place. Alternatively, you can use special nail soak-off caps that come with a gel removal tray. Leave the acetone on your nails for 5-10 minutes. The gel polish will start to dissolve and become gooey.
After the allotted time, remove the foil or caps and check if the gel polish has come off. If not, let your nails soak for a few more minutes. Finally, use a cuticle pusher to gently scrape off any remaining gel polish. Wash your hands and apply cuticle oil or hand lotion to moisturize your nails and hands.
It is important to note that gel nail polish removal can be a lengthy process, and over-scrubbing or forceful removal can damage your nails. Always be gentle and patient during the removal process to maintain the health of your nails.

The science behind colour fading
UV exposure plays a significant role in colour fading. While the initial curing process during the application service involves UV light, it is important to remember that UV rays are present in everyday life, from sunbeds to computer screens and natural sunlight. This additional UV exposure can cause discolouration and fading. The UV rays interact with the chemical bonds in the colourant, causing them to break and alter the colour permanently, similar to how sunlight causes fading in clothing or yellowing in newspapers.
Chemical reactions can also cause colour fading. Solvents like insect repellent and sunscreen contain DEET, which can dissolve and affect nail products. Additionally, certain pigments are more prone to fading due to their chemical structure, especially pinks and corals. Exposure to chemicals during daily activities, such as cleaning or gardening, can also contribute to colour fading.
The stability of the colour formulation is another factor. Nail coatings contain special colour stabilizers, but some pigments are inherently more stable than others. The amount of gel in the product also matters, as the gel creates a protective cover around the pigments, making them less prone to fading.
Furthermore, the application process can impact colour fading. Applying the gel too thinly can lead to fading, while applying it too thickly can cause lifting or chipping. Proper application and the use of a top coat can help prevent fading.
Overall, understanding the science behind colour fading in gel nail polish involves recognizing the effects of UV exposure, chemical reactions, inherent pigment stability, and application techniques. By considering these factors, one can better understand and address the issue of colour fading.
