So sorry for the insanely late reply. I’ve been transitioning from a year of travel and now back to the US. Still readjusting. I don’t know if the photos do justice, but there was definitely a dramatic improvement from just one use of the blackhead treatments. The pores were cleaner, smaller and smoother. But I hear you about regulations and having an understanding of what we put on our skin. To be honest, I don’t know much about Korea’s regulations on these products, but I have to believe that there’s a reason people travel from all over the world just to buy these products. Thanks for the comment and for reading!
