I think the overall concept is great, and while I saw some improvement it ultimately did not perform well for my level of acne. I have deep cystic acne with eczema so I need a product that helps clear my skin but won’t flair up my eczema. When I used curology I found it helped some pimples but those big deep pimples were not much affected. I ended up going back to my dermatologist who put me back on retinols which has cleared up my skin dramatically. As such, I would suggest this to people who do not have severe cases of cystic acne.
