What You'll Learn
- Allergic reactions to gel nails and UV light can be caused by acrylates
- HEMA is a known allergen in gel nail products
- The UV energy emitted by UV light lamps can cause skin ageing and cellular damage
- Allergies to gel nails can be caused by uncured or partially cured gel
- Formaldehyde is a chemical found in nail products that may cause allergic reactions

Allergic reactions to gel nails and UV light can be caused by acrylates
Gel nail products contain a combination of chemicals, including monomers, oligomers, and photoinitiators, which are activated by UV light to harden and cure the gel. If the gel is not cured properly, it can enter the natural nail bed and cause itching and warmth around the nail area. It is important to cure the gel for the recommended amount of time under a UV lamp and to change the UV bulb regularly.
Allergic reactions to gel nails and UV light can range from mild irritation to more severe symptoms, such as redness, itching, swelling, or blisters. These symptoms may appear several hours or days after initial exposure to the gel, or they may take years to manifest as an allergy can build up over time.
If you suspect an allergic reaction to gel nails and UV light, it is important to remove all products, seek medical attention for a proper diagnosis, and treat the affected area with a good oil and lotion. It is also recommended to inform the brand and company of the gel nail product to prevent further allergic reactions.

HEMA is a known allergen in gel nail products
Allergic reactions to gel nails can be caused by a variety of factors, including the gel itself and the UV light used to cure it. While UV energy emitted by UV light is not a common cause of allergies, the gel products contain a combination of chemicals, including monomers, oligomers, and photoinitiators, which can cause allergic reactions. One such allergen found in gel nail products is HEMA, or hydroxyethyl methacrylate.
HEMA is a common ingredient in gel nail products due to its adhesive properties, helping the gel adhere to and last longer on the nails. However, it is also a known allergen and has been identified as the primary (meth)acrylate compound responsible for allergic sensitization. When HEMA comes into contact with the skin, it can undergo a process called "sensitization," where the body's immune system recognizes it as a harmful substance and develops an allergic reaction upon subsequent exposure. This can lead to allergic contact dermatitis (ACD) and other health issues, including nail detachment, severe red itchy rashes, and, in rare cases, respiratory issues.
The risk of developing an allergy to HEMA is increased with overexposure to uncured gel on the skin and nails. Repeated exposure to uncured chemicals can increase the risk of developing an allergy over time, and it is possible to suffer an 'acute allergy' if there has been a reaction to another allergen previously. Symptoms of an allergic reaction to gel nails can include mild irritation, redness, itching, swelling, blisters, hives, rashes, nail detachment, and flu-like symptoms.
To minimize the risk of developing an allergy to HEMA, it is important to limit direct skin contact with HEMA-containing products. This can be done by maintaining a clean work area, using gloves when possible, using tools to clean around the nail, and avoiding skin contact during application. Choosing nail products labeled as "low-HEMA" or "HEMA-free" can also reduce the risk of sensitization. These products use alternative monomers or Bis- or Di-HEMA oligomer chains, which are larger molecules that are not as easily absorbed into the skin.
It is worth noting that while HEMA-free products are available, it is still possible to develop an allergy to other ingredients in these products. Therefore, it is recommended to consult a dermatologist for a patch test to identify specific allergens and to seek medical attention for a proper diagnosis and treatment if an allergic reaction is suspected.

The UV energy emitted by UV light lamps can cause skin ageing and cellular damage
UV-cured gel nail products typically contain a combination of chemicals, including monomers, oligomers, and photoinitiators. These chemicals are activated by the UV energy in the UV light to harden and cure the gel. The photoinitiators in the gel nail products are matched with the nanometers of UV energy emitted by the UV light lamps to 'receive' the energy and start the curing process.
The curing process of gel nail products is important in preventing allergic reactions. If the gel is not cured properly, it can enter the natural nail bed and cause itching and warmth around the nail area. To prevent this, it is recommended to cure the gel for the recommended amount of time under a UV lamp and to change the UV bulb regularly. Additionally, applying thin coats of gel can help ensure that the gel cures well under the light and does not become sticky.
Allergic reactions to the allergens in UV-cured gel nail products can range from mild irritation to more severe symptoms, such as redness, itching, swelling, or blisters. These reactions can appear immediately after exposure to the gel or may be delayed by several hours or days. In some cases, an allergy may build up over a long period of time, and repeated exposure to uncured chemicals can increase the risk of developing an allergy.

Allergies to gel nails can be caused by uncured or partially cured gel
Gel nails are derived from methacrylates and must be cured under an ultraviolet (UV) lamp. The curing process involves activating a combination of chemicals, including monomers, oligomers, and photoinitiators, with UV energy to harden the gel. However, if the gel is not fully cured or cured improperly, it can result in an allergic reaction.
The risk of developing an allergy is increased with repeated exposure to uncured or partially cured gel. This is because the acrylate chemicals in the gel can seep into the skin and cause sensitization. Once an allergy develops, it is recommended to avoid all gel products, even if they are fully cured, as exposure to any type of acrylate can trigger a reaction.
To minimize the risk of allergies, it is crucial to follow the manufacturer's instructions and use the recommended lamp for curing. Additionally, precautions such as wearing gloves during application and removal, ensuring good ventilation, and avoiding skin contact with the gel should be taken.
It is important to note that HEMA (hydroxyethyl methacrylate), a common allergen in nail products, can be found in gel nails. However, advancements in technology have led to the development of HEMA-free gel polish formulas that do not cause allergies.

Formaldehyde is a chemical found in nail products that may cause allergic reactions
While UV light is a known cause of cellular damage and skin ageing, and can increase the risk of skin cancer, it is unlikely to be the cause of an allergic reaction to gel nails. This is because the UV energy emitted by UV light is not strong enough to cause an allergic reaction.
Instead, allergic reactions to gel nails are usually caused by an allergy to the chemicals in the gel nail products. These products typically contain a combination of chemicals, including monomers, oligomers, and photoinitiators. Repeated exposure to uncured chemicals can increase the risk of developing an allergy over time.
Formaldehyde is one such chemical found in nail products that may cause allergic reactions. It is used as a preservative, antimicrobial, and nail hardener in select nail products. Formaldehyde is a recognised carcinogen and a potent allergen in allergic contact dermatitis. It may be listed on the product label as formaldehyde or by different names, such as "formalin" and "methylene glycol".
In nail hardeners, formaldehyde bonds with the keratin that occurs naturally in the nails, making the nails harder. However, using these nail hardeners often may make nails brittle and more likely to break or peel. Nail products that contain formaldehyde may also cause skin irritation, as well as allergic reactions to this ingredient.
If you suspect that you have a gel nail allergy, it is important to inform the brand and company you bought it from and seek medical attention for a proper diagnosis and treatment before changing to another product. This will prevent further allergic reactions and keep you safe.
