Would give it 5/5, but...
unfortunately the price tag dropped it a star. That is really the only thing bad I have to say about this product.
I have been using Dan's Regimen for... oh jeez, almost 7 years now? Anyway, the Regimen is the only thing that has ever truly worked for me. However, recently I have been having acne problems again, not totally sure why (too many variables to narrow it down).
I bought this because I noticed that it had a slightly higher concentration of BP than my normal acne.org stuff, and it also had some LHA for exfoliation. I am glad that I bought it, because it seems to be the extra kick my face needed to start purging itself of the cysts lurking beneath my skin. I still have teeny tiny whiteheads on my forehead, but I think nothing short of an act of God will make those go away.
I only use it once a day, as it makes my skin sensitive and I don't want to overdo it. My facewash is neutrogena ultra gentle hydrating cleanser, creamy formula. My moisturizer is acne.org moisturiser, and after that is finished soaking in, I apply a layer of neutrogena deep moisture night cream to pack it in. Once a week I use a korean face mask for extra moisture.
I have severely dry skin, and this Effaclar Duo (original version, not plus) (U.S. version) did not seem to make it any worse than usual. Of course, I have been using BP for years, so keep that in mind.
