MUST READ! Understanding Gel Allergies

What Causes Them & How to Prevent Reactions

With the rise in popularity of gel polish, builder gels, and polygels, there has also been a noticeable increase in reports of allergic reactions throughout New Zealand. While these products offer long-lasting, glossy results, it’s essential for nail technicians and clients alike to understand the potential risks—and more importantly, how to prevent them.

What Are Gel Allergies?

Gel allergies are a type of contact allergic dermatitis—an immune system response to certain chemicals used in nail products.

The symptoms may include:

• Redness or itching around the nail bed or cuticles
• Swelling or blistering on the fingers or hands
• Peeling or separation of the nail from the nail bed (onycholysis)
• Burning or stinging sensation during or after application 

In more severe or prolonged cases, these allergies can spread beyond the nails to the eyes or face and may become permanent, meaning the client can no longer wear gel products—even in minimal amounts.

What Causes Gel Allergies?

Most gel allergies are caused by overexposure to uncured or under-cured methacrylate monomers, a group of chemicals found in most gel nail systems.

The primary triggers include: 

• Skin contact with uncured product (from flooding the cuticle or sidewalls)
• Improper curing (not using the correct lamp or wrong cure time)
• Improper removal techniques (picking or filing into the skin)
• Low-quality or unregulated products (especially cheap online kits)
• DIY application without proper training or PPE

How to Prevent Gel Allergies (For Nail Techs)

1. Avoid Skin Contact at All Costs 

• Use precision tools and proper application techniques 
• Avoid overloading the brush
•  Do not touch the skin with product or glove-covered fingers
  
  

2. Use a Trusted, Compatible Lamp

• Always cure gel under the manufacturer-recommended LED/UV lamp 
• Under-curing leaves uncured monomer that can seep into the nail and skin
  

3. Wear PPE and Practice Safe Work Habits

• Use nitrile gloves (not latex) and replace them regularly 
• Use a dust extractor or mask when filing cured gel 

4. Prep and Clean Properly

• Remove dust and oils gently—don’t over-file 
• Use a good-quality dehydrator and primer (as recommended by your gel brand) 

5. Educate Your Clients

• Warn against picking or peeling gel 
• Never allow clients to DIY soak-offs or use cheap online kits 

Preventing Gel Allergies (For Clients) Only visit trained professionals who use professional products

• Don’t touch or scratch your nails while the gel is curing
• Follow proper aftercare, including hydration with cuticle oil
• Speak up if you feel any burning, itching, or discomfort during application
• Never attempt at-home gel application unless professionally trained
• What to Do If You Suspect an Allergy If you or your client develop symptoms: Stop using all gel products immediately
• Visit a GP or dermatologist and request patch testing for methacrylate sensitivity
• Avoid reapplication until you are cleared by a medical professional
• Be aware that future exposure, even in small amounts, could trigger stronger reactions
