No — ice drops swelling and redness temporarily but does not shorten the underlying healing cycle. The mechanism is vasoconstriction: cold narrows blood vessels, blood flow drops, the lesion looks smaller for an hour or two. Useful on red inflamed pimples before a photo, useless on blackheads, whiteheads, or comedones. Wrap a cube in clean cloth, 10 minutes on, 10 off, never bare ice on skin — direct contact risks frostbite damage that scars worse than the pimple. Pair with a microdart patch (Rael Microcrystal, ZitSticka Killa) for a deep lesion, or a hydrocolloid patch (Rael Miracle Patch, Hero Mighty Patch, COSRX) for a surfaced whitehead. Those treat the lesion; ice only buys cosmetic time.
