This question is an example of how important it is to use the correct words when speaking about nails and nail products or you may fool yourself into thinking things that are not true! No cosmetic, including nail oils, can make the nail grow any “faster”.
Aceites para uñas: La verdad sobre las afirmaciones de crecimiento
Todo lo que pueda acelerar o acelerar el crecimiento de las uñas se considera un medicamento, no un cosmético. Tal afirmación no está permitida para los productos cosméticos; actualmente, no se conoce ningún fármaco médico que pueda acelerar el crecimiento de las uñas. Tampoco existen vitaminas que puedan acelerar el crecimiento de las uñas. Algunos afirman indebidamente que la biotina acelera el crecimiento de las uñas, pero hay muy pocas pruebas de ello.
There is a very limited amount of evidence that biotin can reduce nail plate brittleness, but there have only been a few small studies and a few dermatologist claims it helped a few patients, but not most.
Cómo ayudan los aceites a alargar las uñas sin acelerar su crecimiento
High quality nail oil can help the nail to grow longer. How is that? Isn’t this also a medical drug or medicine claim? No, it is not the same as speeding up nail growth. To make the nail grow “faster” requires making the nail matrix work faster to produce nail cells more quickly. No cosmetic can do this and it is not an allowed cosmetic claim.
Cómo los aceites reducen la fragilidad y fortalecen las uñas
When certain nail oils absorb into the nail plate, they concentrate between the layers in the upper part of the nail plate where most of the plate’s brittleness occurs.
Los aceites añaden lubricación entre estas capas, lo que permite que se deslicen con más facilidad y, por tanto, se doblen más fácilmente sin romperse. A diferencia de la biotina, hay muchas pruebas de que los aceites penetrantes para uñas reducen efectivamente la fragilidad de la lámina ungueal y de que actúan con bastante rapidez.
Penetrating nail oils contain “lipids”, naturally occurring fatty acids and their derivatives, which absorb to add flexibility and reduce brittleness making the nail plate tougher and less likely to break. They can allow the nail plate to grow longer than it normally would, rather than to break off just past the free edge.
It is perfectly reasonable to expect a good quality nail oil to “help” the nail plate grow longer; while it is unreasonable to expect any cosmetic product or supplement to make the nails grow faster.
Olvídate de los suplementos: Utilice aceites de alta calidad para mejorar la salud de las uñas
Mi consejo es omitir los suplementos nutricionales para el crecimiento de las uñas y utilizar regularmente un aceite para uñas absorbente y de alta calidad para mejorar el estado de la placa ungueal.
These are far more likely to help the nail growth than biotin or any other nail supplement. I recommend using professional quality nail oils, especially those which contain low viscosity, light weight oils such as avocado oil.
Heavy oils and waxes are less likely to penetrate in significant amounts. Keratin doesn’t penetrate the nail plate either, and will remain on the surface. A good rule of thumb to remember is, any oil that won’t quickly penetrate the skin is very unlikely to penetrate the nail plate.
