its propaganda 😹 I used both bars consistently and saw no changes. I mean if you wanna use it to find out for yourself just for satisfaction go ahead but at the end of the day its a waste of money. it also makes your skin feel like rubber once you rinse it off. guys just learn to love yourself the way you are 🤘
