Apply a hydrocolloid patch to a surfaced whitehead and leave it 6 to 12 hours — Rael Miracle Patch, Hero Mighty Patch, and COSRX Acne Pimple Master all pull fluid out by osmosis and turn opaque white when they’re done. Press it onto clean, dry skin, no moisturizer or oil underneath, or it will not stick. For a deep cyst with no surface, switch to a microneedle patch like Rael Microcrystal, ZitSticka Killa Kit, or Peace Out Acne Dots; their dissolvable tips deliver salicylic acid below the stratum corneum. Ice 10 minutes before bed to reduce swelling. The fastest medical option is a dermatologist cortisone injection — 24 to 48 hours to flat.
