I never go a week without using these. These are a life saver especially if you wear make up all the time. They hurt to remove but seeing all the gross gunk that was in your face and no longer is... is just soo satisfying... Use this and then use the freeman lemon and mint clay mask and your face will love you. Just remember to wash your face first and then apply warm water to your nose and do that for about 15 seconds and then use the strip. This will get all those sad pores happy again. I always wait till the strip is REALLY hard before removing them.
