The short answer
Bubbles usually come from air in the gel or a layer that is too thick. Roll the bottle instead of shaking it, apply thin coats, keep the nail dry and clean, and stroke the gel on without overworking it.
Why do bubbles show up in gel polish?
Most bubbles are trapped air. Air gets into the bottle when it is shaken hard, and it gets into the layer when the gel is brushed on too thick or worked back and forth.
Thin, smooth strokes leave less air in the layer, and the layer cures clear.
Should I shake gel polish?
Many techs roll the bottle between their palms or turn it gently instead of shaking it, so no air is whipped into the gel. Follow the instructions on the bottle for each product.
Could the nail be the cause?
Yes. Oil or moisture on the nail can show up as bubbles under the gel. Clean the nail, buff off the shine, dehydrate with pH Bond and wipe off the dust before the base. See How to Prep Nails for Gel.
Does heat matter?
A thick layer can heat up fast while it cures. If a client feels warmth, pull the hand out for a moment and use thinner coats. A low heat mode helps too. See How Long to Cure Gel Nails.
What if a bubble is already cured?
File or buff the bubble smooth, wipe the dust away, then apply a fresh thin layer and cure it. If the bubble goes through the whole layer, soak off and redo that nail.
Does the brush matter?
A clean, well-shaped brush lays gel on smoothly. Wipe the brush on the neck of the bottle before each stroke and keep gel off the bottle rim.
Always follow the label for each product. If bubbles keep appearing, check with your distributor or an instructor about the product, the brush and your technique.
