Common questions
Does Fast Flow mean a shorter full curing time?
The names Fast Flow and Slow Flow describe flow during application. They do not specify a full curing time. Both options require a compatible UV nail lamp. A positioning flash cure must be followed by a separate full cure; flash curing alone does not complete the curing process.
How are these builder gels removed?
The removal method for both NY SUN options is filing. Review the product information and handling guidance before use.
Are both options clear?
Yes. Fast Flow 01 Clear and Slow Flow 02 Clear are both transparent builder gels, each supplied in a 30 g jar.
