I bought this product because of Tanya Burr' raves on it. Unfortunately for me, this would reduce the size of my existing break outs, only to add more big, sore white heads the next morning. It was one step forward and two steps back with this product for me. I have dry skin but it didn't dry me out any further. Has a nice smooth finish and hygienic packaging. I wish this had worked for me like it did for so many others :(

I added this product to my skin care regime but not in a starring role....instead it makes a cameo appearance 2 or 3 times a week. The name of this product is Effaclar Duo-emphasis on "duo". Not only does it contain 5.5% benzoyl peroxide (meant to clean out pores, reduce blackheads and acne congestion) - it also has a lipo-hydroxy acid (LHA) which decongests pores, refines the surface of the skin, and has anti-inflammatory and anti-bacterial effects on the skin.

Certainly there are those people who are going to be sensitive to benzoyl peroxide, especially at 5.5%. Add on the exfoliation that will occur using this product and you can see the potential for some very poor results if used improperly.

My experience has led me to this solution: I use this product as a "preventive measure" on limited areas of my face (only on the nose, in my case) a few times a week. If I have a breakout I MAY apply a small dab directly on the blemish with a cotton swab, but I do not use this product all over my face.

Using Effaclar Duo in this manner has worked beautifully for me. I have always had blackheads around my nose and this product has greatly reduced them. I have never had cystic acne (save for the severe case I had before I learned about mis-using benzoyl peroxide and rubbed a product that contains TEN PERCENT (!) benzoyl peroxide all over my face!). Any breakouts I have now are hormonally induced.

Sigh. I really, really wanted to like this product. I believe there are two formulas of this product. The one that I bought has benzoyl peroxide. If you have sensitivity to benzoyl peroxide, DO NOT USE THIS PRODUCT. I've had reactions to benzoyl peroxide before (haven't used it for about 4 years since). I'm not sure why I decided to try another product with benzoyl peroxide...but since I've been hearing hype about this product, I decided to give it a go! Thinking...maybe my skin has changed in the past 4 years. NO. I tried this all over my face, did not sting, did not hurt upon application. The next day I felt my skin feel dry (note: I have super oily skin). A bit uncomfortable, but definitely manageable. That same day I decided to apply this product as a spot treatment. The next day, my cheeks developed a really, really itchy rash =( Will definitely return this product.

Definitely do not use this if you have sensitive skin or skin that does not work well with benzoyl peroxide (obviously). Normally if I use a benzoyl peroxide product, my skin gets a little irritated and dry. But this time, after only one use of this product, my entire face was swollen and my eye lids were swollen shut. It was very horrific what I had to go through and have never experienced this before. The swelling lasted for 3 days and it only took a few hours to see the swelling. I am probably allergic as other reviewers seem to be getting great results. Never will I use this product again and I cannot recommend this to anyone.

Okay, I use MUA to check reviews on something or other almost every single day but have never ever actually reviewed something myself, but I'm so passionately pissed off right now that I'm gonna do it. Definitely DO NOT use this product if you have *very* sensitive/acne-prone skin. Long story short, I spent the last year in France and while I was there, this product (the French/UK version!!***) was strongly recommended to me by my French derm after having recently come off Accutane. Used it for 2 months before I returned to the US, it was working GREAT and I loved it. When I got home I ran out so I bought what I thought was the same product at Walgreens, without realizing that the American version has 5.5% benzoyl peroxide in it which pretty much makes it A COMPLETELY DIFFERENT PRODUCT and my skin is theeee mosttttttt sensitive. Used it every day for like a week, my face felt like it was on fire and was super red/irritated, then I finally pinpointed this as the culprit and stopped. But it gets better! I woke up the next morning with a MASSIVE breakout, literally 75 (I counted) small pimples concentrated in the areas where I had put the most Effaclar. My skin has not been nearly this shitastic since pre-Accutane. Really maddening experience and I am especially pissed because I looove the French/UK version, will have to order that one online after I get my skin to calm down!

First and foremost, I don't consider spending 14 euros on a skincare product a lot(which is a good thing). Also, I haven't really used this a lot yet, but since it neither brakes me out nor is it drying, I have no problem with it. And most importantly, redness has been reduced, it's moisturizing and non-greasy, plus it proved to be an amazing primer.Honestly my foundation didn't move, although I went from class to night out.

This is probably the best skin care product I have ever bought. I have very pale, combination skin so I find it hard to find products that are gentle enough to take care of my blemishes without irritating my skin. I have been using it for around 3 weeks and it has helped completely clear the persistent spots I had on my chin and even reduced blackheads around my nose. I did find that it slightly dried the more dry areas of my face but just a dab more moisturiser cleared it. Brilliant product and will definitely be repurchasing :)

I'm sorry to say that I'm one of the unfortunate people that this doesn't suit! I have adult acne caused by PCOS & I am always on the lookout for my holy grail acne treatment. I bought the UK version a while ago and noticed that, after a couple of days use, I started to break out in really small whiteheads & sore bumps. I thought it may be my skin 'purging' so I carried on using it but they became more and more frequent to the point where I admitted defeat and stopped using it! Just recently a few beauty bloggers have been raving about it so I dug it out again and decided to give it another go. I had a small spot on my chin at the time and to be fair it did reduce in size overnight but within a couple of days I am now covered in small whiteheads and have a couple of really sore under the skin bumps :-( It seems to work on some spots but causes others?!? Weird. I've decided I must be sensitive to one of the ingredients....sigh...... continued >>

A very effective all over face acne treatment that does not dry my skin out and works overnight. I use European version of this staff and it is as amazing as it was described by some reviewers on MUA. It helped me to get rid of very stabborn small pimples on my chest and back. Skin on my face is usually clear, but I always have some acne on my back and chest. Nothing really worked for this area before, and throurough cleansing only helped a little bit. Effaclar duo is super cheap, so I bought it specifically to use on the large areas of my body. Cleared my acne in two days before the important photoshoot. I now use it every night as a problem skin treatment on my chest and back.

i brought the UK version (made in france) one as everyone on youtube like tanya burr, llymlrs and others were raving about it.I was hoping it would clear my tiny flesh coloured bumps however it Didn't work for me & gave me more actual red spots around my nose area. Didnt feel like it helped any blackheads either! So dissapointed, thought it was just a waste of money! BP usually works for me and as the 'made in france' version dosen't have it, i would recommend the 'made is US' version as it does have BP as an ingredient. continued >>
