I highly recommend this product in combination with other Biomedic products from LaRoche-Posay for the treatment of stubborn acne. I had trouble with moderate to severe acne for most of my 20s. I tried everything – accutane, 5 kinds of antibiotics, differin gel, ortho tri-cyclen + aldactone, stuff from tv, and oftentimes, I used several of the treatments in combination, as directed by my ever-hopeful dermatologist. Finally, I went to a plastic surgeon to see about some scar treatments, and before he did any major procedures, he put me on a combination of effaclar K, a couple of other biomedic products, Retin-A micro, and I had regular micro-dermabrasion and/or facial peel treatments. Retin-A Micro gave me really dry skin, so after I cut that out, everything else worked perfectly. I know other people’s recommendations can be annoying, especially when you’re certain that nothing will work, but I’d say that this product is worth a try! It really did help me. I continued to use it even after I stopped going to regular microdermabrasion appointments, and I have never had a reoccurence of acne. (As a side note, I also avoided major plastic surgery as a result of the success.)

I love this product! I have tried literally hundreds of beauty products from many countries and in every price range. I’ve used cetaphil and creme de la mer… However, I can say that after two months of using this product it is the best thing I have found for my acne-prone skin. As my dermatologist always emphasizes after I tell him I feel like I’m wasting my money, there is no such thing as a miracle. He’s right, and I still get some breakouts, but this has helped- noticeably.
It also did not dry my skin the way all other acne products seem to do. I pair it with LRP’s toleriane moisturizer and I get no flakes at all, and almost no zits. Best thing I’ve ever found for my acne; in my case better than prescription gels or antibiotics. My skin started getting better in a few days, but give it a try for at least 2-3 weeks since it takes some people longer to see results.

I wish I had found this product long ago.
It is the only thing I’ve actually rated 5-star on Amazon because I believe it rates it.
It reduces visible zits when applied directly to them- sometimes in just a couple of hours.
When applied to the whole face after a warm shower just before bed, you wake up with a clearer, cleaner, tighter face. The acidity kills acne-causing bacteria on and below the surface of the skin, dissolving oily residue, preventing clogged pores, and eating away dead skin.
I found this product in Paris, and a few years later it started to be exported to the USA. Until then, I was spending alot of money to purchase and ship it here into the USA where I live. Now that it is available on Amazon.com, I’m so overwhelmed with happiness.
I cannot possibly say enough. This stuff really is that good. 10/10!!!

I know that everyone is different but after reading all of the really good reviews, I just had to try this. It is kind of expensive but I purchased it anyway. I figured that if it worked, it would be worth it. This did nothing for me.
(
I tried this for a couple of months and my face actually got worse. It helped to clear up any developed blemishes faster than they would on their own but it seemed to irritate my skin and cause it to break out more often.
I was also careful not to change anything else about my routine so that I could give this a fair shot…..
Oh well, I am off to try the [...] regimin and see how that goes. I will post a review on that later.

I bought this and the Laroche Evaclar face wash. It’s been exactly one week today that I got it from Amazon and started using it. Let me tell you, this stuff is amazing. As good or better than the reviews on amazon say. I have not had one new zit since last weekend and any zits I had when I started using this are gone now. I’ve been getting these deep zits since I was like 13, so it’s taken me 10 years to find something that works this good. In one week I feel much more confident than I have in years. They say to wait for 2 weeks for full results, and if I’m this satisfied now it can only get better. You really feel clean when using this product. All I need now is something to diminish a few small scars I have from years of zits. I don’t think Laroche has a product like that yet.
