Hi,
Most pimple patches are actually hydrocolloid wound dresssings to assist in wound healing. Some may contain mild levels of salicylic acid that helps dry out pimples. Acne patches may have a role in aiding skin healing together with proven medical treatment.
However, cystic acne is due to deep intense inflammation that will cause significant scarring if not treated quickly and effectively. For cystic acne, the most effective treatment is oral isotretinoin.
It is strongly recommended that you see a doctor early to commence on effective treatment in order to reduce scarring. Relying just on acne patches will simply not work.
Hope this helps!
