Basic question for any cleanser-does it leave my face clean? Absolutely, it does. Would I use it this type of cleanser to remove make-up? No. Therein lies the perplexity of a very expensive cleaning product for my face. This is a specialty cleanser to use either in the morning alone in the shower or after I've already used another product to initially remove the day's make-up. Oh the steps we go through to maintain our skin!
I used it almost daily in the morning having a 1 ounce tube that lasted at least a good month, so if you're looking at a 5 ounce tube costing $35 at the infamous cosmetics store that should last you about 1/2 a year, not bad on the wallet if it fares well for your skin. However, I do think there are lesser priced products that can do the same job.
As to living up to its claims of perfecting your pores, removing oil and impurities and minimizing pore size, does it do the job? I don't have a problem with pore size, so I can't comment on that issue, nor do I have oily skin any longer. This cleanser does remove what I have on my skin overnight to a squeaky-clean finish without drying it. What I did find interesting is that it seemed to smooth my skin and create an even palette for my morning routine. Not that it erased any wrinkles or fine lines, it just seemed to slightly minimize or plump them, if that's possible.
I used it during both warm and cold temperatures and found it works well for my dry skin, leaving it feeling moisturized and not dry regardless of the humidity. That's a plus not having to switch a product because of the outdoor weather.
Two cons to this cleanser for me. The smell is atrocious. I literally had to hold my breath while using it, it's that bad. I'm not asking for a perfumed product, but I'm also not asking for a product that smells so horrible I gag. I would also prefer a pump style rather than a tube because of the product's texture. It's easy to lose excess while pouring it out because it's runny. At the cost of it, I'd rather not pour extra out and be able to monitor my usage.
Would I purchase it again? No, simply because of the smell.
