Please do not get discouraged if you have a burning sensation.
This product is supposed to exfoliate your skin while you sleep. So while there is a slight burn once put on, it goes away. If it does not go away after a minute or two definitely wash it off. I've felt the burn but never had any problems with it going away. I like it, it makes me feel like it's working.
I have adult acne which I battle. If I've had a bad bought of Acne and it's passed, my skin and other products have done their job, I still need to heal up the skin and remove the bad stuff. This helps get deep down so that even if you choose to use an exfoliant the following day (I recommend) this product has done it's job to loosen it all up and exfoliating then removes it off of your face leaving healthy less pigmented skin.
I can say I get better healing, less scars and a faster turn around time with dark spots ever since I've added this.
I admit it is very pricey. I recently found a brand that does not test on animals and use the same kind of form. I am hoping it will work as good as this.
Speaking of finances, I use a clean cotton pad and soak up the fluid and apply. This helps the container last a lot longer for me then if I just used their pads and tossed it. Which is really helpful financially.
While it's very rare I get to have Arcona products, they do seem to give me benefits. I have noticed other brands here on Birchbox that seem to do much of the same and again With Out testing on Animals. Thank you Birchbox for helping me find a much more affordable replacement. For those who can afford it I can say this particular product does a great job.
