Too much work
My skin is a combination type so I struggle with a lot of oil production BUT dehydration-prone type. So, I was actually skeptical about this product. However, it did the job for me just fine at the end? It actually reduced all the redness around my T-Zone. Also it is really effective against new appearing pimples. Like, give it two days and it will heal just because of this cleanser. I noticed how it reduced the blackheads and big pores too. So, the aspect of it fighting acne is great and not a scam. The aspect of it giving the “squeaky” clean feeling after cleansing should be taken with a grain of salt. Does it make wonders helping with acne and oil production? Yup. Will it dry your skin out? Hell yeah. So it is totally the product which will work ONLY for oily skin or combination skin without high sensitivity. It is a way straight to the grave for people with other skin types. Me, as an oily girly, survived it just because I moisturized my skin properly after. The negative aspect is that it made me purge. Like, it took me two weeks to get used to this cleanser but it worked out at the end at least. I will also bring out how dehydrating it is. In the end, it can work out in special conditions and if you will try to make it work. But should you go through 5 stage of grief pain anger and finding right conditions just for the [already expensive] product to work out when you can just find the good one which will do it for you? Exactly. I will give it 3.5 stars just because it is usually targeted as an acne fighter. And this warrior is strong in it. But drying struggle is real… Where is the gentle aspect of it? Beware. TL;DR: Great for fighting acne but too drying.
