The Koji White Difference
"I’ve been using this since November 1st and it’s now February 25th and i still have the 2 soaps and I LOVE THIS, I leave it on for 10-15 min while I brush my teeth then rinse it off & use it with cerave but that’s an alternative."
"I would say each to their own on this product. I like it and have no problems like I've seen listed. I did try it on my arm first just in case. It does dry my skin out a little but I think that's to be expected"
"My skin doesn’t feel dry or stripped, just refreshed and rejuvenated. The soap lathers really well, and the scent is light and pleasant. Good thing 2 comes in a pack so I never have to worry about running out. If you’re looking for a way to brighten your skin, fade dark spots, or even out your tone, this soap is a must-try. It’s truly a 5-star product for glowing, healthy skin."
"I had purchased acid soap in the past, but couldn't find anything that actually would lighten my blemishes. I get mosquito bites often and they leave scars that heal poorly. Been using this on old scars and my skin appears vastly improved. The blemishes won't disappear, but the Koji Soap does work to minmize their appearance."
