Understanding Heat Spikes in Gel Polish

Gel polish has emerged as a game changer offering long lasting, chip resistant colour that keeps your nails looking flawless for weeks. For those new to the gel polish realm, encountering a heat spike during the curing process can be a cause for concern. Fear not, as this phenomenon is not only normal but also harmless. Let’s delve deeper into this intriguing aspect of gel manicures and debunk any myths surrounding it. 


What Exactly is a Heat Spike?

A heat spike refers to a sudden sensation of warmth or heat experienced by some individuals when their gel polish is being cured under a LED lamp. It typically occurs within the first few seconds of the curing process and may feel slightly uncomfortable or surprising. Rest assured, it's a transient sensation that dissipates quickly.

Why Does it Happen?

The primary reason behind heat spikes lies in the chemistry of gel polish. Gel polish formulations contain photoinitiators, which are compounds that react to the specific wavelengths of light emitted by LED lamps. These photoinitiators kickstart the polymerisation process, causing the gel polish to harden and adhere to the nail surface.

During this polymerisation process, a small amount of heat is generated as a byproduct. When the gel polish is applied in layers and cured under a lamp, this heat can accumulate, resulting in the sensation of a heat spike.

Is it Normal?

Absolutely. Heat spikes are a common occurrence in gel manicures and are experienced by many individuals, especially those with sensitive nails or skin. It's important to note that not everyone will feel a heat spike, and its intensity can vary from person to person.

Is it Harmful?

Rest assured, a heat spike during the gel curing process is completely harmless. The amount of heat generated is minimal and does not pose any risk to your nails or skin. Our One Step Gel polish undergo's rigorous testing to ensure it is safe for use, including assessing it's reaction to curing lamps.

Tips for a Comfortable Gel Manicure Experience

While heat spikes are normal and harmless, there are a few tips to make your Esmio manicure experience even more comfortable:

  3. Consider Sensitivity: If you have particularly sensitive or thin nails or skin, you may experience more pronounced heat spikes. Consider using Cuticle Oil everyday to keep them nourished and strong.

  4. Experiment with Techniques: Explore different curing techniques, such as using shorter curing intervals to find what works best for you.
