This is a product I haven't used since I was a teenager. I loved them then and they disappeared mysteriously from the market. With their reappearance I decided to give them a try.
I must admit this is a highly effective way of keeping your pores clean, though stripping this thing off your nose is a traumatic experience.
I don't think there strips differ much brand to brand, Beauty Formulas are widely available and affordable so I might stick to them.
