No. Squeezing a pimple pushes bacteria and inflammation deeper into the skin, which usually makes the spot bigger, redder, and longer-lasting, and raises the chance of scarring or dark marks. Hydrocolloid patches are designed to work on a pimple that's surfaced naturally, drawing out fluid through the patch material rather than through forced extraction. If a whitehead has come to a head on its own, gently cleanse and dry the area, then apply the patch, it'll absorb what's there safely. If you've already popped a spot, a patch can still help by protecting the area, absorbing residual fluid, and keeping your fingers off it while it settles.
