 Why do B-Flex and B-Strong give a fantastic shine in 30 seconds soft in a smart light? Well, it's because of the formula. Don't forget that B-Flex and B-Strong are all-in-one gels. So they are gels that need to adhere to the nail plate, they need to construct, and they need to also have a fantastic shine. And therefore their formula is balanced. And a balanced formula also requires a balanced curing. And balanced curing means a gradual curing, which where the light intensity in the beginning is low and it gradually increases. The reason is that when we do a gradual polymerization of the gel, then we get a much nicer, much orderly curing through the entire gel and a much smoother surface. And the smoother the surface, the higher the shine. If we were to give 30 seconds full curing light, then we would have very quick polymerizations locally. And this will cause contractions on the upper layer. And you would have all kinds of imperfections. And these imperfections, when the light falls on them, will be seen as a matte surface. So even if you use B-Flex or B-Strong as a final gloss layer, a thin layer, still remember to cure it in 30 seconds soft to get this very nice, smooth surface. Also good to know, if you have very sensitive clients, you can also use 60 seconds soft, which makes the curing process even more gradual.
