Amazing!
I had a breakout of adult acne due to stress. I should’ve read the ingredients list but I initially had a horrible reaction against the medication I was taking. After adjusting the dosage and checking how much my skin could tolerate, I’ve been using this at night on alternative nights alongside antibiotics tablets. Previously my skin was reacting terribly but for the last two months I have seen major improvement. The acne was so bad that wearing matte makeup made it look worse. Not I can wear matte make up and not feel horrible. I’m hoping to using sheer make up with blemish corrections soon.

Cleared my Skin up in 6 weeks
I suffer with hormonal, bacterial acne. In summer months it worsens, I was hunting for a routine to keep blemishes at bay. I have been using this for 6 weeks, morning and night with my cleanser. I can honestly say its changed my skin, I don’t have spots come as much, it’s made scars fade and skin overall looks brighter. It’s a must for me now!
* it did cause my skin to “purge” that lasted about a week.

Burnt my skin
My face was on fire for days after using this serum. Gave me a chemical burn! Feels too strong and I can't find any information on what is the concentration of acids in there.

Sensitive skin... Doesn’t work. If you have acne……
It didn't work for me. My skin is sensitive and I have mild acne, but this product helped increase my tolerance to acne and now I have two problems. I had no results in 4 weeks of application, as mentioned in the packaging that it would have worked. I stopped using it.

72 yr old with consistent blackheads and whitehead
A miracle for me. Post menopausal spots. After just 3 nightly applications on my face tightened pores. I also steam and use a 'scrubber'..I'm also using the Vit C serum during the day.

Massive break out
I’m posting this again as my first review was deleted and no reply or reason was given.
Is this meant to cause a breakout ?
I’ve used this product twice in a week and followed the instructions, I have now got lots of small bumps and lots of spots all over my face where I didn’t have them before, is the normal ? Should I continue ?

good but strong
this is strong so using it first every 2 days or so, as the skin barrier can be affected

It made my skin a LOT worse
My skin is sensitive and acne-prone. I only used this serum twice but my whole face is now covered with small bumps. They’re itchy and kind of red as well. My skin is so rough to the touch. It is such a disappointment for an expensive product. Please evaluate your serum. Make it better.

Is this suitable for Rosacea
The Effaclar Serum is designed to help care for blemish-prone skin, specifically. For rosacea-prone skin, please find more information on LaRoche Posay Rosaliac AR Intense Localized Redness Serum, here: https://www.laroche-posay.co.uk/en_GB/rosaliac-ar-intense-localized-redness-serum/LRPUK-031.html

Hiya, Can this be used with retinol?
It contains salicylic acid which is a BHA (chemical exfoliant) so not a good match with retinol due to risk of irritation
