Preparation: Complete a standard hygienic manicure, shape the free edge, lightly buff the nail plate with a buffer, and thoroughly clean away all dust.

Prep & Prime: Wipe the nail surface with a professional dehydrator (Nail Prep) and apply a thin layer of acid-free primer (Ultrabond). Let it air dry.

Base Layer: Apply your chosen professional base coat, shape the correct nail architecture, and cure (60 seconds in an LED lamp).

Color Application: Give the bottle a light roll between your palms to evenly distribute the reflective glitter. Apply a thin, smooth layer of the Spark gel polish across the nail.

Curing: Polymerize in a professional 48W LED lamp for 60 seconds. If a deeper color depth or higher glitter density is required, apply a second thin layer and cure again.

Sealing: Lock in the brilliant sparkle with a glossy, high-shine professional top coat (e.g., Saga Top) and cure for 60–90 seconds.
