What are heat spikes and how can i combat them?

We have all had a client quickly whip their hand out of the lamp because they are experiencing a heat spike. Understanding why they happen can help us reduce the occurrence of heat spikes.

Ultimately heat spikes occur due to the exothermic reaction that takes place when the gel polymerises (cures) under UV or LED light. 

First we have to look at what polymerisation is…

Polymerisation occurs when the photo initiators in the gel are exposed to UV or LED light, they trigger a chemical reaction that causes the gel to harden. This reaction releases energy in the form of heat. Polymerisation happens with every nail gel that cures under UV/LED light and a certain amount of heat will always be expelled by this reaction. 

There are several reasons why the sensation of a heat spike may occur;

  1. Rapid Curing: The faster a gel polymerises the more heat is generated in a shorter period.
  2. Gel Thickness: Applying the gel too thickly can cause more intense heat spikes. Thicker layers have more material reacting simultaneously, producing more heat. It's generally recommended to apply the gel in thin, even layers to reduce the risk of heat spikes.
  3. Intensity of the Lamp: High-intensity lamps can cause a faster and more intense reaction. If you have previously been using lower quality / intensity lamps you may notice a difference in the heat being felt by your clients when moving onto a higher intensity lamp.
  1. Type of Gel: Different gels have varying formulations. Some gels may contain higher concentrations of photoinitiators, making them more reactive and prone to heat spikes.
  1. Nail Condition:
    1. Sensitivity: Individuals with thinner or more sensitive nails may experience more intense heat spikes. The heat from the exothermic reaction can penetrate more easily, causing discomfort.
    2. Damage: Nails that are damaged or have been filed too thin can also be more susceptible to heat spikes.

How to Minimise Heat Spikes

  1. Thin Layers: Apply the gel in thin, even layers to reduce the amount of heat generated at one time. Remember that each layer of gel applied to the nail plate will act as an insulator, protecting the nail plate from heat.
  2. Gradual Curing:
  • Flash Curing: Cure the gel for a few seconds initially, allowing the reaction to start slowly before completing the full cure.
  • Low heat mode: Some lamps have settings to start with a lower power for the initial curing stage.
  • Follow manufacturers guidelines: Use high-quality gels and follow the manufacturer's instructions for application and curing times. If you are experiencing a lot of heat spikes, contact your manufacturer and seek advice on what you can do to alter your application to reduce them.
  • Cooling: If you feel a heat spike starting, you can briefly remove your hand from the lamp to cool it down before continuing.
  • Proper Lamp Selection: Choose a lamp with adjustable settings and one that is compatible with the type of gel you are using.
  • Season: Heat spikes are more common in the summer months. We believe that this I because the gel has a higher starting temperature but still has to undergo the same amount of polymertisation to cure, thus leading to a higher peak in temperature. Try cooling your gel before use (water in a Tupperware with ice packs works well)

By understanding the causes of heat spikes and taking appropriate steps to mitigate them, you can ensure a more comfortable and successful gel curing process.
