Apply a microdart patch the moment you feel the deep ache, before the bump surfaces. Rael Microcrystal or ZitSticka Killa both use 24 dissolvable cones to deliver 2% salicylic acid and niacinamide past the skin barrier into the forming lesion — ZitSticka reports 85% of users see reduced size and color when applied early. Wash with a gentle salicylic cleanser, dry the skin, press the patch on, leave 6 to 8 hours. If the bump has already broken the surface with a whitehead, switch to a flat hydrocolloid: Rael Miracle Patch, Hero Mighty Patch, or COSRX overnight will flatten it by morning. Ice 10 minutes on, 10 off to drop swelling. Skip squeezing and toothpaste.
