The Importance of Using the Correct UV/LED Lamp for Gel Systems

In the nail industry, achieving a flawless and long-lasting gel manicure isn't just about the skill of the technician or the quality of the gel polish, it's also about using the right UV/LED lamp. The lamp plays a crucial role in the polymerisation process, ensuring that the gel cures properly, providing durability and safety for your clients. Let's dive into the science behind this and understand why using the correct lamp is so essential when knowing how to cure gel polish. 

The Lamp's Role in the Polymerisation Process

 Polymerisation is the chemical process that transforms the liquid gel into a hard, durable coating. This process is triggered by UV light, and there are three critical factors to consider: wavelength, intensity, and curing time. Each of these factors is crucial for ensuring a proper cure. 

Gel Nail Lamp Wavelength

UV/LED lamps contain LED bulbs that emit UV light, specifically UVA rays. The wavelength of these rays must be within the range of 365-405 nanometres. This specific range is crucial because the photo initiators within the gel react to this exact wavelength, kick-starting the polymerisation process. 

Different gel systems may require slightly different wavelengths within this range to cure effectively. Therefore, it's vital to use a lamp that matches the gel system you are using. Using an incorrect gel nail lamp can lead to under-curing, where the gel remains soft and prone to lifting, peeling and allergies, or you can get over-curing, which can cause heat spikes and the gel to become brittle and prone to cracking. 

Intensity and Time

Most UV/LED nail lamps offer a range of curing times, typically from 10 seconds to 99 seconds. This flexibility allows technicians to manage the intensity of the cure according to the needs of the product being used. 

When curing at full intensity, the UV light penetrates the surface layer of the gel quickly, starting the polymerisation process. However, for thicker consistency or highly pigmented products, a full intensity cure can be problematic. The surface layer may cure too quickly, preventing the UV light from penetrating into the deeper layers, leaving monomers and oligomers unreacted. This can compromise the durability of the manicure and potentially cause damage to the natural nails. 

To address this, most lamps offer a 'low heat' mode. This mode allows for a lower intensity cure over a longer period, enabling the UV light to penetrate through the surface layer to the bottom layers of the product. By curing from the bottom up, this method ensures a thorough and safe cure for thicker or more pigmented gels. 

Ensuring Complete Polymerisation

 To guarantee complete polymerisation and achieve a safe, durable, and professional finish, it is imperative to match your UV/LED nail lamp with the gel system you are using. Here are some key takeaways to ensure you are using the correct lamp: 

  • Check Compatibility: Always ensure that the lamp you are using is compatible with the gel system. Manufacturers typically provide guidelines on which lamps work best with their products. 
  • Follow Manufacturer Instructions: Adhere to the recommended curing times and intensity settings provided by the manufacturer. These recommendations are based on extensive testing and are designed to ensure optimal results. 
  • Invest in Quality: High-quality lamps may have a higher upfront cost but are worth the investment. They provide consistent and reliable curing, which is essential for maintaining the integrity of your work and the safety of your clients. 
  • Regular Maintenance: Keep your lamps clean and well-maintained. Dirty or old bulbs can reduce the effectiveness of the UV light, leading to incomplete cures. 

By understanding the critical role of UV/LED nail lamps in the polymerisation process and using the correct lamp for your gel system, you can ensure that your manicures are not only beautiful and long-lasting, but also safe for your clients. This attention to detail will set you apart as a professional and help you build a loyal clientele who trusts in the quality of your work.
