the brand is Dr. Song 2.5% BP gel
you can check reviews by those who bought it and half of them are ex acne.org users. hope that helps;)
I buy all from amazon. Excessive postage fees on acne.org makes it impossible for me to order directly from this website. Today, I found another brand that sells on amazon a very good alternatives to acne.org products which you can buy cheaper and with guaranteed delivery by amazon. Good luck to you:)
Do you mind sharing the alternative brand you found? I'm starting to get quite tired of the super slow and expensive shipping of acne.org products, even from amazon.
