Since hydrocolloid attracts water and fluid, Mighty Patch works best on pimples that have come to a head (in other words, you can see white fluid or pus trapped in the pimple). If you tried a Mighty Patch and it didn’t change from transparent to opaque white, your pimple might not have been “mature” enough or the right type of blemish.
If you have cystic acne, we recommend you see a doctor or dermatologist for professional treatment.
