These are some of my favorite pimple patches! I prefer pimple patches that have tea tree or salicylic acid on them, they just seem to work better for me than plain hydrocolloid patches. These have salicylic acid along with carrot and ginger extracts. They work so well at reducing the size of larger pimples and it usually only takes about 2 days of putting patches on to clear them up. Smaller pimples clear up in a day or so with these. These stick very well too. Comes with 4 different sizes of patches and the carrot print ones are adorable.
