Poke gel is a nail art gel that reacts when you poke, scratch or drag a clean tool through it before curing. Instead of spreading like a bloom gel, it pulls back from the mark and rounds out, so the cleared areas grow into soft, rounded openings. That makes it suited to bubble letters, cartoon-style outlines, rounded abstract shapes and lava-lamp style patterns.
Apply and cure the base layer the poke gel method calls for, then apply a thin, even layer of poke gel and do not cure it yet. While it is wet, poke, scratch or drag into the gel with a clean tool; the exposed areas expand and round out. When you like the design, cure straight away to lock it in, then add details and a top coat.
The usual causes are the base and the amount of gel. Poke gel is meant to be worked over a base made for it; a regular base gel does not give the same reaction. A thick layer of poke gel or a light touch with the tool also weakens the effect, so use a thinner layer and firmer, deliberate strokes, and wipe the tool between strokes.

Yes, once the poke gel layer is fully cured. You can add fine line art, use chrome or pigment on the surrounding cured areas, and finish with a gloss or matte top coat. Cure every layer completely before adding the next one, and seal the edges with the top coat so the design wears evenly.
