I bought these after a blogger said they were her favorite, but I don't think they are as effective as the Dr. Belmeur patches in dealing with occasional pimples. 

This is already the second time I`ve ordered this product, it is that good. I am new to Korean skin care, and I think I`ve fallen in love with COSRX`s products. :-)

I use this to prevent myself from touching my pimples!
