An “exotherm” is a scientific term that means \u201cto release heat\u201d. This is what occurs when nail coating products get hot during application. It is commonly known as heat spikes. Both UV gels and L&P systems can become warm, even hot during application. Becoming warm isn\u2019t a problem, and is considered normal for products that cure or polymerize to create a nail coating. But when the coating overheats, this can be painful for clients. Even so, nail coating exotherm (EK-so therm) can cause other problems besides burning pain. This type of overheating can lead to nail bed damage and infections. It is important to understand why these issues occur so that you can avoid them. Let\u2019s look at the most common reason clients feel excessive heat when these types of products cure.<\/p>\n\n\n\n

UV gels and monomer liquids are both made using acrylic ingredients and chemistry, and there are N\u00c3O<\/strong> exceptions to this rule. Curing occurs as millions of tiny, invisible molecules begin to permanently join together to create many growing polymer chains. Each time two molecules react to join together, there is a release of a very tiny amount of heat. The heat released by one molecule joining a chain is FAR too small to detect. However, when a coating cures on a single nail plate, it contains many millions of molecules. Many millions of molecules joining together release millions of times more heat. Of course, this normally occurs on every nail plate, and usually doesn\u2019t create any problems. However, excess heating can become painful and potentially damaging under some circumstances. This can occur with all types of artificial nail coatings and adhesives. <\/p>\n\n\n\n

When nail coatings are properly formulated, properly applied, and properly cured, the small amount of heat that is released usually goes unnoticed. Some products are not properly formulated, and may have a tendency to overheat, even when properly applied. This is unusual because reputable manufacturers run quality control tests to ensure the heating is controlled so that it won\u2019t become excessive. This is one of many reasons for only purchasing such products from reputable manufacturers. Nail product developers pay very close attention to this issue, and design their products to slowly release heat during curing, rather than to suddenly release it as heat spikes.<\/p>\n\n\n\n

Even normal levels of heat become much more noticeable if the nail bed is injured, e.g. from aggressive over filing. Why? The nail plate insulates the nail bed from heat but, if the nail plate is overly thinned by filing, it becomes a poor heat barrier. This allows heat to flow through the plate into the nail bed, in some cases to cause injury.\u00a0\u00a0Also, overly aggressive filing techniques can \u201cfriction burn\u201d the nail bed, making it super-sensitive to even small amounts of heat that would normally go unnoticed. For example, if I rub my arm with my fingers five times, that doesn\u2019t harm it but, if I do that 500 times, I\u2019m likely to damage the surface of the skin.\u00a0\u00a0Or if I push down harder and rub 50 times, I can still friction burn my skin. The same is true when filing the nail plate.\u00a0<\/p>\n\n\n\n

Do not burn the nail bed! File gently and avoid coarse abrasives that thin the nail plate. The nail bed doesn\u2019t contain any heat detectors but does contain pressure detectors. You can feel these detectors activate if you pressed down hard on the nail plate. That\u2019s why you can feel applied pressure to the nail bed. However, when the nail bed gets hot enough, this will trigger the pressure detectors to create painful burning sensations. Generally, these detectors won\u2019t be triggered until the temperature of the nail bed exceeds 115o<\/sup>F ou 46o<\/sup>C. Quando isso ocorre, as termina\u00e7\u00f5es nervosas sob a placa ungueal podem disparar como um alarme de inc\u00eandio no c\u00e9rebro. O c\u00e9rebro envia um sinal forte de dor ao leito ungueal para avis\u00e1-lo do perigo em potencial. As queimaduras por fric\u00e7\u00e3o podem danificar o leito ungueal, torn\u00e1-lo muito sens\u00edvel e fazer com que ele reaja de forma exagerada at\u00e9 mesmo a temperaturas quentes. <\/p>\n\n\n\n

Using the wrong polymer powder with the monomer liquid can definitely cause these types of nail coating products to overheat. That is why it is important to only use polymer powders designed for the monomer liquid of your choice.\u00a0\u00a0\u201cFast setting\u201d nail coatings actually release the same amount of heat as those with a traditional set time, however, they do so in a shorter time period. This heat may go unnoticed when released over two or three minutes, but this same amount of heat becomes very noticeable when released in one minute or less. This is especially true if the nail bed has been friction burned by overly aggressive filing techniques. Fast-setting nail coating products aren\u2019t for everyone. They are best used in cold climates. That\u2019s because the room temperature plays a big role in determining how quickly these l&p nail coatings will harden (polymerize).\u00a0\u00a0Fast set nail coatings are much more likely to overheat when used on warm days.\u00a0\u00a0\u00a0\u00a0\u00a0<\/p>\n\n\n\n

Curado por UV Os revestimentos de unhas de gel tamb\u00e9m podem gerar calor<\/a> spikes, especially on friction-burned nail beds.\u00a0\u00a0Heat spikes that occur during the cure of UV gels can be caused by using the incorrect UV nail lamp. For example, a UV gel nail coating designed to cure with traditional, fluorescent style UV nail lamps will likely overheat when cured with a LED-style UV lamp. LED-style UV nail lamps produce more UV than traditional style nail lamps.\u00a0\u00a0That\u2019s why they cure nail coatings more quickly. <\/p>\n\n\n\n

Riscos de cura inadequada e aplica\u00e7\u00e3o espessa em revestimentos de unhas de gel UV<\/h2>\n\n\n\n

When a UV gel nail coating designed to cure in 2 minutes under a fluorescent-style UV nail lamp is cured in 30 seconds with a LED-style UV nail lamp, all of the heat is released in one quarter of the time.\u00a0\u00a0This is what can create painful burning sensations, and that may result in onycholysis (on-EE-ko-LY-sis), or separation of the nail plate from the nail bed.\u00a0\u00a0Onic\u00f3lise<\/a> can lead to nail bed infections. Of course, there are other reasons for onycholysis. No matter which type of nail coating you use, the more thickly the nail coating product is applied, the more heat will be released. That\u2019s often why larger thumb plates feel warmer, compared to smaller nail plates.\u00a0<\/p>\n\n\n\n
