La Roche-Posay Effaclar Range Explained

Okay, so I promise I'll change the record after this post, but just let me say it one more time: I Love La Roche-Posay. Yes, I've gotten some for free, but I have been a longtime fan of the brand, and more specifically the Effaclar range, since I first picked up Effaclar K about two years ago.

I recently posted about two LRP products that were working particularly well for me, and mentioned that I found the difference between Effaclar K and Effaclar Duo to be quite unclear.

Seems I wasn't the only one left scratching my head.  A girl called Emer left a comment asking us to clarify if what she was doing was correct - she had been told by her local chemist to use Effaclar K as a moisturiser and Effaclar Duo as a spot treatment for morning and night. I had no idea how to answer her query, as I was confused enough myself!

So I got on to the brand's PR to see if she would have the info. She very kindly got in touch with the Irish LRP medical manager, who trains pharmacy advisors all over Ireland. Here's what she had to say:

She recommends breaking the products down as follows –

Effaclar Duo – A dual action product that treats on the surface (spots) and below the surface (clogged pores, whiteheads and blackheads) as well as reducing redness and inflammation. It is for daily use all over the face.

Effaclar K – Again suitable for all over daily use, this deals with congestion below the surface of the skin – blackheads, uneven surface, bumps. It doesn’t deal with inflammation or actual spots.

Duo is more suitable for acne-like skin imperfections whereas K would be a milder treatment for a less aggressive condition.

In terms of the question from your reader, we would be more likely to recommend Effaclar AI (Anti-Imperfection) than Effaclar Duo as a localized treatment. It is perfect for breakouts or individual spots (combats redness, reduces scarring and accelerates skin healing). It's perfect for occasional or localized use combined with Effaclar K.

So there you have it. They are both all-over treatments, but serve different purposes. I would be inclined to use one or the other at night (perhaps start with Duo and when your skin clears up a bit move on to K) and use a decent moisturiser in the morning. My top picks for oily skin would be LRP Hydraphase UV, Vichy Normaderm Tri-Activ, or LRP Effaclar M, which all retail for under €20.

I really hope that this helps, French pharmacy products can be confusing enough and when I turned to Google for more information, there wasn't a whole lot there either. I think that this is down to the fact that the directions on the packaging of these two products aren't quite specific enough - I was informed that PR are working to rectify this, and improve the communications for this line.

Let me know if you've tried any Effaclar products and how you got on with them!

La Roche-Posay is available from many Irish pharmacies as well as Boots, and you can find it online at Escentual.


  1. My current moisturiser is a Le Roche-Posay one (The intense fluid one I think) and I have to say I love it, I'm nearly out but will definitely be re-purchasing it. It is really hard to know which is the best one to go for though, they don't have a lot of info on the bottles so I'm glad to hear they're working on rectifying this.

  2. i did a post all about the other side of the coin with how La Roche-Posay can help dry skin, instead of oily skin

    love this post btw!.x

  3. Have a much better understanding of the Effaclar range now thanks very much! :)


  4. Thank you so much for that information! I bought the Effaclar K and A.I. along with Cicaplast in Paris last summer but stopped using both Effaclar products after a week or so, as i didn't like how they behaved under foundation (rubbing off in little rolls) + I had more breakouts than usual after using them. Now after reading about the 'initial purging' reaction that Sinéad experienced and your advice of using them at nighttime, i'm willing to give them another try :)
    Me too I love this post and your blog in general x

  5. Hi I was wondering if you could help? I am a little confused on how to use the range, I started with the duo as my moisturiser both day and night and used the ai on specific spotty areas. Recently I have bought the effaclar k and am using it as a night treatment then the duo in the morning, is this right? I am totally lost! x

  6. Hi Thanks For The Information!! When You Say Combine Effaclar K With AI....what do you mean and how ?

  7. I just wanted to let you know I mentioned you in my Effaclar K review here ( Thanks so much for helping me work out the differences between the two products! x
