What are nail design LED gels? Can we now expect a large change in nail design gel products? This depends on the individual, because every innovation has its advantages and disadvantages. However it must be pointed out that use of the LED technology is spreading. What is special about LED gels? They are of the highest quality and are easy to use. When you do your fingernails with LED gels, you will notice that you won’t feel any heat development. The typical heat with UC gels does not occur with the LED design technology. And LED light offers the advantage of a much shorter working time. Before you work with LED gels you should understand all the nail design information about LED gels and hardening. LED gels have a hardening time of generally 30-90 seconds. To harden the LED gels you need, of course, a nail design LED lamp.
