It is our mission to make manicures easier, more affordable and safer.
As part of this mission we are committed to providing education of the potentially harmful products and ingredients found in the industry, how we are trying to improve upon them, and things you should be aware of when performing manicures at home.
A 2016 study at The University of Miami’s Dermatology Dept. found that 1–3% of the population is sensitized to at least one ingredient found in nail cosmetics. One common ingredient, 2-hydroxyethyl methacrylate (HEMA) has a reputation on social media as harmful and is a very common ingredient in Gel nails and acrylic nails. However, it's important to understand that scientific studies have shown limited dosages of HEMA pose no harm or risk when applied correctly to only the nail plate. The risk increases if the ingredient is applied to the skin directly or does not cure completely. For these reasons we are taking extra precaution to craft our Colorcure™ Gel contains less than 1% of HEMA, with a goal to provide HEMA free formulas for those with a known allergy.
HEMA, or 2-Hydroxyethyl Methacrylate, is a chemical compound commonly used in the formulation of nail products, particularly in gel nails and acrylic nails. It serves as a key ingredient in many nail adhesives and gels because it can undergo polymerization, leading to a hard and durable finish when exposed to ultraviolet (UV) or LED light.
While HEMA itself is not inherently dangerous, its use in nail products can pose certain risks, and it's important to be aware of these potential issues:
Skin Sensitization and Allergic Reactions: Some individuals may develop sensitivities or allergies to HEMA, which can result in symptoms like redness, itching, swelling, and rash, particularly around the nails. Allergic reactions to HEMA are a concern, and people with a history of skin sensitivities should be cautious when using products that contain it.
Contact Dermatitis: Prolonged or repeated contact with HEMA-containing nail products can lead to contact dermatitis, an inflammatory skin condition. Proper application and removal procedures are essential to reduce the risk of skin irritation.
Inhalation Risk: Nail technicians who work with HEMA-containing products may be exposed to vapors and fumes. Proper ventilation and the use of personal protective equipment can help minimize inhalation risks.
Potential for Overexposure: Overexposure to HEMA, particularly during the curing process (UV or LED exposure), should be avoided. Nail technicians should use protective measures to limit their exposure to UV or LED light.
Cancer Concerns: Some studies have suggested that exposure to HEMA and other methacrylates may be associated with an increased risk of cancer, particularly in individuals who work in nail salons and have prolonged, chronic exposure. However, more research is needed to establish a definitive link.
To minimize the potential risks associated with HEMA and other methacrylates in nail products, it's crucial to follow the manufacturer's instructions for proper application, curing, and removal. Additionally, nail technicians should take steps to protect themselves and their clients from excessive exposure to these chemicals, including proper ventilation, use of personal protective equipment, and being vigilant about potential allergic reactions or skin sensitivities. If you experience adverse reactions, consult a healthcare professional or dermatologist.
Methacrylates are commonly used in the formulation of nail products such as acrylic nails, nail gels, and nail adhesives. When used correctly and in accordance with manufacturer recommendations, these products are generally considered safe for most people. However, there are potential risks associated with the use of methacrylate-based nail products, and it's important to be aware of these risks and take appropriate precautions:
Allergic Reactions: Some individuals may develop allergic reactions to the chemicals in these products, including methacrylates. Symptoms of an allergic reaction can include redness, itching, swelling, rash, and in severe cases, contact dermatitis. If you suspect an allergic reaction, it's important to discontinue use and consult a healthcare professional.
Skin Irritation: Prolonged or repeated contact with methacrylate-based nail products can lead to skin irritation, especially around the nails and cuticles. It's essential to follow proper application and removal procedures to minimize the risk of skin irritation.
Inhalation: Nail technicians and people working with these products may be exposed to vapors and fumes, which can potentially be harmful when inhaled over extended periods. Adequate ventilation is crucial in nail salons to reduce exposure to these fumes.
Proper Application and Removal: It's important to follow the manufacturer's instructions for application and removal of nail products. Incorrect application or aggressive removal techniques can damage the natural nails and surrounding skin.
UV/LED Curing: Some nail products require the use of UV or LED lamps for curing. While the exposure is usually minimal, it's a good idea to protect your skin from excessive exposure to these lamps.
Overall, the key to using methacrylate-based nail products safely is to follow the instructions provided by the manufacturer, be aware of potential allergies or sensitivities, and take precautions to minimize exposure to fumes and skin contact. If you experience any adverse reactions or have concerns, consult a dermatologist or healthcare professional for guidance.
If someone is allergic to gel nail products that contain HEMA (2-Hydroxyethyl Methacrylate) and the product touches their skin, they should take immediate steps to minimize the potential for an allergic reaction or irritation. Here's what they can do:
Wash with Soap and Water: Immediately rinse the affected area with soap and lukewarm water. Gently scrub the area to remove any residual product.
Avoid Rubbing: Avoid rubbing or scrubbing the area harshly, as this could exacerbate the irritation.
Apply an Over-the-Counter Hydrocortisone Cream: If there is redness, itching, or irritation, you can apply an over-the-counter hydrocortisone cream to the affected area. Follow the package instructions for proper usage.
Use a Cold Compress: Applying a cold compress can help reduce any swelling or inflammation.
Monitor for Allergic Reactions: If the person is known to have a severe allergy to HEMA, they should monitor the area for signs of an allergic reaction. These may include hives, intense itching, redness, swelling, or difficulty breathing. If any severe symptoms develop, seek immediate medical attention.
Seek Medical Help: If there is a severe allergic reaction or if the irritation persists, it is crucial to seek medical help promptly. In such cases, a healthcare professional may prescribe stronger medications to manage the symptoms and prevent complications.
To prevent future occurrences, it's important for the individual to avoid products containing HEMA if they have a known allergy to it. If they want to continue using gel nail products, they should consult with a dermatologist or allergist for potential allergy testing and recommendations for alternative nail products that are less likely to cause an allergic reaction.
- Check the Curing Time: Follow the CNVS instructions for proper cure time.
- Visual Inspection: After the recommended curing time, visually inspect the nails. They should appear completely hardened and solid, with a glossy finish. Gel nails that are fully cured will typically have a glass-like appearance.
- No Tacky Layer: If the gel glue leaves a tacky or sticky layer on the surface after curing, make sure to wipe it off using a cleansing solution. Once you've removed the tacky layer, the nails should not feel sticky or tacky.
- Assess Adhesion: Ensure that the veneer is securely attached to your natural nail. If the gel has cured correctly, the tip should be firmly bonded without any lifting or separation.
- No Residue: There should be no residue or uncured gel visible around the edges or cuticle area. All parts of the gel should be uniformly cured.
Wash with Soap and Water: Immediately rinse the skin with soap and lukewarm water. Gently scrub the area to remove any residual product. Begin the application process again.
- Irritation can also occur if the gel does not fully cure. This primarily occurs if you use too much product or do not leave your fingernail under the LED light for proper curing time. Please refer to the application instructions and our YouTube video for application instructions.
- Our nail veneers are designed to be translucent enough to allow LED light to fully cure the gel glue, however pigmented enough for them to be beautiful right out of the box, with no additional paint required if you would like.
- Follow our application instructions to ensure you are curing them sufficiently. If you notice that they are not, remove veneer and follow our instructions for application. See above section regarding How do I know if the Gel is Cured?
