I have tried the original cosrx pimple patches and I have to say these work FAR better! Although, slightly more pricey in comparison, they are just way more effective and the sizes that you get work better. I also find that the ‘sticky’ power of them is much better and don’t come off when you put them on before bed. It’s worth noting though, that pimple patches usually only work with spots that have a head. These are somewhat effective on under the skin bumps but don’t always completely flatten - hence why I’ve given 4 stars :)
