Rated 5 out of 5 by from Thank you Just love all the range . I hit menopause and my skin went from bad to worse . I was on holiday in Italy and went ina chemist and they gave me it. That is 4 years ago I use everything . I absolutely love it . I’ve introduced my daughter and friends and they all say they have improvement.

Rated 5 out of 5 by from The only thing that worked for me! Thank god I bought this serum - for 2 years I have had textured skin, small bumps and blocked pores that spread across my forehead and cheeks and no spot cream or facials would improve it, until I tried this. I have been using it for about 2 weeks and the improvement is insane. My skin feels softer and I can visibly see a reduction in the amount of bumps I have now. Really hopeful to continue using this, it has been a miracle product after trying sooo many things with no results

Rated 5 out of 5 by from Amazing serum Another fantastic serum from la Roshe posay. I had thyroid cancer and had my thyroid removed and got really bad hormonal breakouts constantly, this is one of the products among other la Roshe posay products, after trying soo many others, this was the only thing that actually cleared my skin for good. I hardly ever get any breakouts anymore after using this. This serum is great for clearing any blemishes and blackheads quickly from the skin. Also leaves skin very smooth soft and glowing. Little goes a long way and bottle lasts a long time. This is a product I repurchase time and time again. Highly recommend.

Rated 2 out of 5 by from caused breakouts for me I used only this product alongside a moisturizer I have been using for years and the morning after using this product, every time, i break out. I try to use it only every few days but to no avail. I then went on vacation and didn't use it at all, and my skin cleared up. would not recommend

Rated 1 out of 5 by from Awful - Very Disappointed I actually tried this a while back and did get in touch with La Roche Posay at the time and was told that what I experienced was very unusual but after reading some of the reviews on here it was not. My skin also burnt terribly after using this product so much so that I had to wash it off my face. I tried it a couple of times and the same thing occurred. I don't have any issues with any of the other Effaclar products I use and I also use Retinol every night with absolutely no problem. I did give it to a friend who had no issues with it so I am not sure what the actual problem with it is.
