Prevention tips
To prevent yellowing of gel nails, it is important to understand its causes. While the yellowing of gel nails is generally not a safety concern, it is still a cosmetic issue. One of the primary factors contributing to this issue is the presence of photo-initiators, a common ingredient in the curing process of many gel products. Additionally, excessive sun exposure is the most common cause of yellowing. The UV light from the sun reacts with the chemistry of the nail application, altering its colour.
- Use a quality product like SNS GelStar nail gel or SNS dip powders, which are crafted with ingredients to maintain their premium colours for the entire lifetime of the application.
- Get your nails done by an SNS Certified Nail Artist to ensure proper application and reduce the chances of yellowing.
- Cover your nails if you're spending a lot of time in the sun. You can also use a new product with enhanced sun protection, like SNS's Sealer Dry formula.
- Wear gloves when handling dyes, chemicals, or spending time in a chlorinated swimming pool to create a barrier and protect your nails.
- Apply a top coat from any brand to your nails after a manicure to prevent discolouration.
- If you regularly work with paints and dyes, apply petroleum jelly to your nails as a protective layer.
- Rinse your hands with water and soap immediately after using any staining products, such as makeup.
- Choose high-end gel polish brands that incorporate "optical enhancers" or "optical stabilisers" into their formulations. These enhancers are designed to counteract the yellowing effect, keeping the gel clear even after curing.

Possible causes
Yellowing of the nails is a common issue that can occur with gel manicures. While it may not be aesthetically pleasing, it is important to note that it is typically not a safety concern and is usually harmless. Here are some possible causes of yellowed gel nails:
Excessive Sun Exposure
Prolonged exposure to the sun is one of the most common causes of nail discolouration. The UV light from the sun reacts with the chemistry of the nail application, altering its colour. This can happen even with high-quality gels and dip powders, as they can only withstand a certain amount of direct sunlight. Similarly, artificial tanning can also lead to nail discolouration.
Chemical Exposure
Various chemicals can cause nails to turn yellow. This includes exposure to chlorinated water in swimming pools, hair dyes, certain makeup products, household cleaning agents, spices like turmeric, and even some hand sanitisers. If you regularly come into contact with these substances, it is advisable to wear gloves or apply a protective layer, such as petroleum jelly, on your nails.
Nail Polish and Removal
The use of certain nail polishes, particularly darker colours, can contribute to nail discolouration. The pigments in these polishes can migrate and leach into the nail during the removal process, causing a yellow tint. Additionally, the harsh removal process of gel and acrylic manicures, which often involves soaking nails in acetone, can dry out the nails and make them more susceptible to discolouration.
Fungal Infection
In some cases, yellow, thick, and "crumbly" nails may indicate a fungal infection. However, it is important to consult a dermatologist for an accurate diagnosis, as nail discolouration can have various causes.
Application Errors
Sometimes, yellowing can occur due to errors during the application process. This may include contamination of the nail product or improper curing, leading to a yellowish tint.

Natural cleansers
While yellowing of the nails is generally not a safety concern, it can be unsightly and embarrassing. The good news is that there are several natural ways to brighten yellowed gel nails.
Lemon
Lemon contains natural bleaching properties that can help remove yellow stains from nails. You can directly rub a piece of lemon on your nails or make a quick lemon juice soak.
Vinegar
The acidic nature of vinegar helps remove stubborn stains from hard surfaces, including nail polish stains. To prepare a vinegar soak, dissolve 1 tablespoon of white vinegar in a bowl of warm water. Dip your fingertips in the solution for no more than 5-10 minutes, then rinse your hands with warm water and apply moisturiser.
Petroleum Jelly
If you regularly work with paints and dyes, applying petroleum jelly to your nails can help prevent stains. It is best to wear gloves, but if you can't, this trick will help protect your nails.
It is important to note that if your nails are yellow, thick, and "crumbly," you may have a fungal infection and should consult a dermatologist. Additionally, if you are a frequent smoker, the tar and nicotine can lead to nail stains, so it is advisable to avoid smoking or wear gloves to minimise direct contact with the nails.
