I love these strips. I purchased twenty boxes when I was in Thailand because they were so cheap there at the time.
I find them very expensive in South Africa in comparison, so I now use them more sparingly.

I love how easy they are to use, and effective! It is so satisfying to examine the strip after ripping it off. You can clearly see all the junk that it extracted from your filthy pores. It drastically reduces black heads from the first use. I used to use it two to three times a week until I found out what they cost here. Now once weekly is sadly what we are down to.
