So low-key I only use glue ons and as long as it’s not bad and covering the entire nail/on every nail your fine to put a fresh set on (of glue ons NOT POLISH) file it down and use alcohol to dry it out and it should go away even w nails on. It’s from moisture, so you may need to adjust the amount of glue your using, and take them off once they start to lift
Yeah I try not to re glue more than 1 time because it just doesn’t seal to the nail right. Most brands say 7 day wear to prevent the ‘greenies’. It take practice but you’ll get the hang of it. It’s hard bc too little and it won’t get the edges, too much and it will get everywhere and when the excess glue chips off it allows water to get in as well
