This is one of the most effective pimple patches that I've tried. It will heal your pimple 1-3 days but will leave no trace. It is relatively cheap because it already has 60 patches compared to Skinfood (12 patches) and Cosx (24 patches). I will repurchase this!
i like to use these during the day because they are so thin, it's not as noticeable and protects your acne from getting dirtier.
