Informações gerais

Recentemente, uma profissional de unhas fez uma ótima pergunta: “Can you leave your UV/LED nail lamp plugged in indefinitely without causing damage?” Many people leave electronic devices plugged in for convenience, but this practice might not always be advisable for nail lamps. Let’s explore the safety and maintenance aspects of keeping your nail lamp plugged in.

O impacto de deixar sua lâmpada para unhas conectada à tomada

Can leaving a UV/LED nail lamp plugged in cause damage? Even when not in use, most lamps draw a small amount of “standby power,” which can activate components like timers or touch sensors. Over time, this minimal power consumption might not immediately harm the lamp but could contribute to the gradual degradation of its electronic components, especially in cheaper models.

Exposição ao calor quando conectado à tomada

Embora os LEDs em si não gerem calor quando a lâmpada está desligada, uma conexão de energia constante pode levar a um pequeno acúmulo de calor em outros componentes internos. Isso pode estressar o circuito com o tempo, principalmente em lâmpadas sem projetos resistentes ao calor ou ventilação adequada.

Desconexão da tomada para evitar danos

The simplest measure to avoid any potential issues is to unplug the nail lamp when it’s not being used. This completely cuts off any power draw and ensures no internal component remains active unnecessarily. If it’s essential to keep the lamp plugged in, using a surge protector can offer protection against voltage spikes, which are particularly harmful to sensitive electronics in budget-friendly models.

Armazenamento adequado e conexão prolongada ocasional

O armazenamento adequado da lâmpada de unha em um local fresco e seco a protege contra danos ambientais, como umidade e poeira, que podem reduzir sua vida útil. Mas e se você se esquecer de desconectar a lâmpada de vez em quando? Felizmente, as lâmpadas de alta qualidade são construídas para resistir a esses descuidos sem danos significativos. No entanto, deixar a lâmpada constantemente conectada à tomada pode aumentar o risco de falha prematura, especialmente nos modelos de menor qualidade.

Recomendações finais sobre como deixar sua lâmpada para unhas conectada à tomada

Para maximizar a longevidade de sua lâmpada de unha:

1. Desconecte-o da tomada quando não estiver em uso, especialmente por longos períodos.
2. Utilize um protetor contra surtos para maior segurança.
3. Sempre guarde a lâmpada em um local fresco e seco para evitar danos ambientais.

In conclusion, while occasionally leaving your nail lamp plugged in won’t necessarily destroy it, regularly unplugging it can greatly extend its operational life and help avoid unnecessary repairs or replacements. By practicing moderate use and proper care, you can keep your nail lamp in excellent condition for years to come!s

In this final part of our series on the key properties of natural and artificial nails, we focus on wear resistance. Wear refers to the ability of a surface to resist abrasion or rubbing over time. As we’ve already explored strength, hardness, flexibility, toughness, brittleness, and solvent resistance, understanding wear is crucial for maintaining the longevity and durability of both natural and artificial nails.

O que é resistência ao desgaste e por que ela é importante?

Wear resistance describes how well a surface can withstand abrasion or damage caused by rubbing and scraping. For nails, wear resistance ensures that they do not wear away too quickly from daily activities like typing, cleaning, or filing. Both the natural nail plate and artificial nail coatings benefit from wear resistance, as tougher and harder surfaces tend to last longer and maintain their appearance.

Nail plates have a relatively low hardness compared to other materials, largely because they contain a significant amount of water. On the Mohs scale, natural nails have a hardness of 2, while artificial nail coatings typically range between 2 and 3. This means artificial coatings often provide a tougher, more wear-resistant surface than natural nails but when our artificial nail is harder than the natural nail we need to be aware of maintenance and care, it can’t just be hard it also needs to be flexible.

Dureza do prego e resistência ao desgaste

Nail hardness is a major factor in wear resistance. Harder materials tend to resist abrasion better than softer ones. For example, diamond, which has a hardness of 10, is one of the hardest substances and is often used in high-quality nail files. In comparison, natural nails and most artificial coatings fall far below this level of hardness, meaning they are more susceptible to wear. Silicon carbide, a common material used in nail files, has a hardness of 9, making it nearly as effective as diamond in abrading nail surfaces.

Nail files with high hardness materials, such as diamond grit or silicon carbide, can be overly aggressive if not used carefully. These files can wear down artificial coatings quickly but more so the nail plate, potentially causing excessive thinning and damage. Aluminum oxide, a softer abrasive with a hardness of 7.5, is less aggressive but still significantly harder than natural nails. This makes it an ideal material for nail files because they are gentler on the nails mas resistente o suficiente para fazer bem o trabalho. Quase todas as limas de óxido de alumínio são brancas, mas verifique com seu fornecedor para ter certeza.

Como os abrasivos afetam o desgaste das unhas

Abrasive particles in nail files scratch away the surface of the coating to shape and smooth it. For the natural nail, we only need the file to shape the free-edge. A 180 grit Aluminium Oxide Spong File can be used with care to ‘etch’ the surface of a natural nail and also tip to remove any little bits of nail at the free edge (those irritating little bits of nail that can cause so much trouble at the free edge when applying gel polish after filing into shape)

Coarse-grit abrasives with larger particles create deeper and wider scratches, while finer-grit abrasives create smaller and shallower scratches. Heavier grit abrasives can cause excessive thinning of the nail plate, especially if used with heavy pressure. Even buffers, which are meant to etch the nail surface, will cause damage when over excessive pressure is used. Damage done with a nail file on the nail surface cannot be recovered without using an intensive nail recovery system of which there is only one – not recovering the surface of the nail plate will not only disturb the balance of your nail coating but also seriously diminish the wear time.

A resistência ao desgaste das unhas está intimamente ligada à dureza, pois materiais mais duros tendem a resistir melhor ao desgaste. As unhas naturais que são mais frágeis correm um risco maior de desgaste, e a solução geralmente é aumentar a flexibilidade por meio de tratamentos como aplicações de óleo quente. Essa flexibilidade adicional ajuda a proteger as unhas contra o desgaste excessivo.

Maximizando a resistência ao desgaste para a saúde das unhas

To ensure optimal wear resistance, it’s important to maintain a balance between toughness and flexibility in both natural and artificial nails. For artificial coatings, using products that offer a combination of strength and flexibility can improve wear resistance and longevity. For natural nails, keeping them hydrated and using treatments to enhance flexibility can help prevent wear and damage over time.

In conclusion, wear resistance is the final key property that ensures the durability and health of both natural and artificial nails. By understanding how wear, hardness, and abrasives interact, nail care professionals can make informed decisions to protect their clients’ nails from excessive wear.

In this sixth part of our series on the key properties of natural and artificial nails, we’ll explore solvent resistance. As we’ve already discussed properties like strength, hardness, flexibility, toughness, and brittleness, solvent resistance is another critical factor that helps maintain the health and longevity of both natural and artificial nails. Solvents are liquids that dissolve solids or other liquids, and in nail care, it is important to understand how different solvents interact with nails, especially with artificial coatings.

O que é resistência a solventes e por que é importante?

Solvent resistance refers to a material’s ability to withstand the effects of liquids, such as water or acetone, without breaking down or dissolving. Water is known as the “Universal Solvent” because it dissolves more substances than any other liquid, but it doesn’t dissolve natural or artificial nails. Both types of nails are resistant to water, which is crucial since regular exposure to water would otherwise cause damage over time.

Embora as unhas naturais possam absorver pequenas quantidades de água e outros solventes, elas não se dissolvem neles. Essa resistência a solventes garante que as unhas naturais permaneçam intactas mesmo quando expostas à umidade. As unhas artificiais, entretanto, normalmente são mais resistentes à absorção de água, mas podem ser afetadas por outros solventes, como a acetona, que é comumente usada para remover esmaltes e revestimentos artificiais.

Dureza das unhas e resistência a solventes

Nail hardness plays a significant role in determining a nail’s resistance to solvents. Artificial nail coatings, such as acrylics and UV gels, vary in their resistance to solvents based on their formulation. For example, methyl methacrylate (MMA) and certain UV-curable gels are highly resistant to solvents like acetone, making them more challenging to remove. These coatings can take an hour or more to dissolve in acetone, indicating high solvent resistance. However, this same resistance to acetone can also prevent the penetration of nail oils, which are essential for maintaining flexibility.

Em contrapartida, alguns revestimentos de unhas artificiais são formulados para se decomporem mais facilmente em acetona, tornando a remoção mais rápida. Esses revestimentos tendem a absorver os óleos das unhas com mais eficácia, permitindo que mantenham o equilíbrio necessário entre flexibilidade e resistência. Quanto mais resistente a solventes for um revestimento, maior será a probabilidade de ele resistir tanto à acetona quanto aos óleos das unhas, o que pode afetar a flexibilidade das unhas.

O papel da acetona na resistência a solventes

A acetona é um dos solventes mais comuns usados no tratamento de unhas, principalmente para a remoção de revestimentos de unhas artificiais. Sua ação é rápida, penetrando na maioria das unhas artificiais dentro de dez a vinte minutos. No entanto, o tempo que a acetona leva para quebrar um revestimento pode variar muito de acordo com o tipo de produto para unhas artificiais usado.s coatings to acetone also provides insight into their ability to absorb other substances like nail oils. Nail coatings that take longer to break down in acetone are often less likely to absorb nail oils, which can reduce the flexibility of the nails over time. When applying nail maintenance, it’s important to realise that applying oil behind the free edge essential is to prevent unnecessary brittleness of the natural nail under the nail coating. On the other hand, coatings that dissolve more easily in acetone are typically better at absorbing oils, which can help increase the nail’s flexibility and prevent brittleness.

Acetone Science Check

Acetone does not damage, weaken, or change the structure of the natural nail plate.
It does not denature keratin or cause permanent harm.

Acetone temporarily removes surface oils and moisture, which can make nails feel dry. This is a cosmetic effect, not structural damage, and is fully reversible with proper hydration and regular use of nail oil.

Como tratar a fragilidade das unhas com óleos para unhas

When natural or artificial nails become brittle, restoring flexibility is key, and nail oils are highly effective in achieving this. These oils penetrate the nail plate and help restore flexibility by balancing out strength and hardness. Nail oils can penetrate most artificial nail coatings. To improve penetration, warming the nail oil to slightly above body temperature (around 100°F or 38°C) can significantly speed up absorption for all nail coating users but especially for those with brittle nails.

Natural nails, despite their resistance to solvents like acetone, have built-in channels that allow for the transmission of natural oils from the nail bed to the nail plate. These oils, which include substances like squalene, help maintain nail flexibility. While some believe that nails can’t contain oils because they lack sebaceous glands, this is just not true. The underlying tissues of the nail bed produce oils including squaline, contributing to the overall health and flexibility of the nail plate and the nail unit.

Maximização da resistência a solventes para a saúde ideal das unhas

Manter a resistência a solventes nas unhas artificiais é essencial para garantir sua longevidade e desempenho. No entanto, essa resistência deve ser equilibrada com a capacidade de absorver os óleos das unhas, pois os revestimentos de unhas excessivamente rígidos podem levar à fragilidade. No caso das unhas naturais, minimizar a absorção de água e manter o teor de óleo natural ajuda a preservar a flexibilidade e evita rachaduras.

Concluindo, a resistência a solventes é uma propriedade importante das unhas naturais e artificiais, protegendo-as dos danos causados por líquidos como água e acetona. Compreender como essa resistência interage com outras propriedades importantes, como a dureza e a flexibilidade das unhas, permite que os profissionais de cuidados com as unhas façam escolhas informadas sobre os produtos, os produtos de manutenção e os tratamentos que usam.

In this fifth part of our series on the key properties of natural and artificial nails, we examine brittleness. We’ve previously covered strength, hardness, flexibility, and toughness, all of which play crucial roles in maintaining nail health. Brittleness, however, occurs when the balance between strength and flexibility is lost, causing nails to break easily, even under minimal stress or impact. Understanding brittleness is essential for both natural and artificial nail care, as it affects the durability and resilience of the nails over time.

O que é fragilidade e como ela afeta as unhas?
Brittleness occurs when a nail lacks flexibility and becomes prone to cracking or breaking without bending. A great comparison can be made with bones—children’s bones are flexible, but as we age, our bones lose flexibility and become brittle. The same happens to nails. When a nail is brittle, even a small impact or snag can cause it to break, crack, or shatter without much force. For example, clients might claim that their nail “just broke” while doing nothing; this could indicate that their nails have become brittle over time, so some small (unnoticeable) trauma was enough to break (brittle) the nail.

Brittleness can develop in artificial nails or nail coatings as well, though it typically takes a little time for this to become noticeable. This could be due to the specific formulation of the product used, or brittleness may result from improper curing. When brittle artificial nails break, it is often accompanied by a snapping sound, but when a nail coating breaks it usually quietly fractures and we don’t notice until we wash our hair or the nail coating snags on our clothing, this needs to be fixed as soon as possible to stop pathogens from nestling between the nail coating and the nail bed as water from simple things like washing our hands can be a starting point for the development of an infection because pathogens love warm cozy places and a few drops of water. This can be easily avoided with a quick removal and replacement of the damaged nail coating.

Dureza e fragilidade das unhas: A conexão
Brittleness is closely tied to nail hardness, as a nail that becomes too hard and loses its flexibility will crack or shatter instead of bending. While nail hardness refers to a nail’s ability to resist surface damage like scratches, brittleness describes the nail’s tendency to break without bending. Nails that are too hard without enough flexibility will inevitably become brittle, resulting in a higher likelihood of damage. Artificial nail coatings, like hard UV gels, are sometimes brittle if they are too rigid and lack the necessary flexibility to bend with the natural nail.

A perda de flexibilidade geralmente é a principal responsável pela fragilidade. Quando as unhas não conseguem mais se dobrar sob pressão, é mais provável que se quebrem. É por isso que manter um equilíbrio entre dureza e flexibilidade é fundamental para prevenção de fragilidade em unhas naturais e artificiais.

*** A unha natural sob o gel está em movimento contínuo e, se for frágil, ela se curvará para longe do revestimento da unha na borda livre, o que, combinado com um gel frágil, é uma receita para o desastre. ***

Causas e reversão da fragilidade
Several factors can contribute to nail brittleness, including age, diet, overall health, and environmental exposure to cleaning agents and solvents. Artificial nails can also become brittle over time, particularly if improper curing has occurred or if the product’s formulation doesn’t maintain the right balance of flexibility and strength.

Fortunately, there are ways to address and reverse brittleness. Since brittleness occurs due to a loss of flexibility, the best solution is to restore flexibility in the nail plate. High-quality nail oils or solvent treatments containing Allantoïne and or Ureum are highly effective in combating brittleness. These oils and natural moisturisers absorb into the nail plate, increasing its flexibility and restoring the balance between strength and flexibility. Good quality nail oils work similarly to leather conditioners, which soften and reduce brittleness in leather with the added ability to hold water at bay.

Os óleos para unhas de boa qualidade podem penetrar tanto nas unhas naturais quanto na maioria dos revestimentos de unhas artificiais, com exceção de alguns revestimentos curados por UV com superfícies que resistem à penetração; os géis duros são um bom exemplo disso. Isso também se aplica a solventes como a acetona, que pode ter dificuldade para penetrar nesses revestimentos de gel UV mais duros.

Restaurando a flexibilidade para reduzir a fragilidade
Para reverter a fragilidade, é importante manter a flexibilidade das unhas. Isso pode ser feito com a aplicação regular de [TS1] good quality nail oils. These oils help restore the nails’ natural elasticity and help prevent further cracking or shattering. By focusing on flexibility, both natural and artificial nails can maintain their durability and appearance over time.
