It's only effective for pimples which almost "ripe", use it at night before sleep and leave it till morning, see your pimple's content out and stick to the patch, but when your acne is still deep under (only feel bump on the skin) it practically has no effect on it whatsoever.

Creo que hay que probar  para tener una opinión. A mi me ayudó bajando la inflamación pero hizo más lenta el proceso de cicatrización. Creo que debes probar y sacar tus conclusiones porque el precio lo permite,

i have a super bad habit of popping my pimples, so these are life savers. it works effectively on both super agitated pimples and on blemishes that havn't quite risen to the surface of the skin. it deters picking and popping and protects the pimple. its not a complete miracle worker, but it works well enough that i will be repurchasing. 

This helps calm my acne and reduces my acne scarring and blemishes!
