Been using this soap for almost 3 weeks and ive been noticing my stubborn dark marks are fading but I know I still have long ways to go. I love the way it leaves my face feeling nice and smooth. Smells great. Its the only cleanser I use now unless I breakout, so i use my salicylic acid cleanser. The bar is pricey so I cut it into cubes so 1 bar should last for 1 1/2 to 2 months. Im looking to really transform my skin so I am considering purchasing the kit.
