 Why is it important to fully cure your color? In fact, there's three very good reasons for that. First of all, it's important for the adhesion of the color to the builder gel. So you want to avoid chipping at all costs. Another important thing is that if your color is not fully cured and you apply your gloss layer over it, it will eventually sweat through the gloss layer and it will make it less shiny. So it will become matte. And the third reason that you should cure your color correctly is to avoid allergies. Allergies for yourself as a nail technician when you're doing the refill because the powder will come everywhere on your hands and your client's hands, but also for your client because you do not want her running around for four weeks with an uncured color on her fingers.
