Love this Serum noticed a slight change and only been using for around a week


I was looking for something to help calm and treat breakouts and I like this serum because I can see the difference overnight! It's not going to get rid of your spots instantly but I definitely notice that the redness and swelling of spots is reduced when I wake up in the morning. It's great for when you can feel a breakout coming on and you can treat straight away!


Great serum I use morning and evening on my acne prone skin I think it has helped it look more radiant. It leaves my skin feeling soft although I do find the texture of the serum a bit sticky.


I have struggled with ance and blackheads since I was a teenager. My skin is now at the point where the spots have calmed down but I have lots of enlarged pores and blackheads. I was a little worried this would upset things and cause new breakouts but after 2 weeks of using morning and night I have seen improvements in my skin texture. My skin looks brighter and clearer, I'm sure there is even some improvements in the awful blackheads on my cheeks, they seem smaller. The few spots I've had seem to have cleared up and healed quicker. A little goes a long way and one blob from the dropper covers the whole face.


miracle in a bottle. greatly reduces spots overnight. can’t recommend enough.

It’s really nice and not harsh on my sensitive skin. You also barely use any and it goes a long way! This has helped to clear up my blackheads

Pauline Lamont

This makes such a difference to my skin, it’s noticeable in the morning. My skin is smoother and just nicer!


Lovely silky serum that is keeping my breakouts at bay


I find most BHA products too harsh for my sensitive skin, but this is not harsh at all. It actually feels moisturising and doesnt make your skin feel tight or sore. It has made such a difference to my skin. Before I would get a lot of spots and redness, I do get some of that, but I do notice a big improvement using this serum. I use it at night and will continue to re-purchase!


Really great product for mild to moderate acne


Stings a little but nothing too uncomfortable. Really helped improve my skin and redness


I've been using this for a month or so now. This stuff seems to work really well at busting blackheads on my problem areas (nose and cheeks). However, it doesn't seem to do much in terms of minimising my pores. The serum makes my skin very shiny for a couple of hours after use so I don't apply in the morning, but rather apply at night after washing my face. Additionally, I really dislike the dropper/applicator - it doesn't "drop" well at all and I worry how I'll get the serum out when it starts to run low. Hopefully FaceTheory find a better dropper by the next time I purchase. Nevertheless, I'll definitely keep using this serum because of the success I've had with blackheads, which I'd been self-conscious about for a long time.


Great stuff

One of my favourite products now x

Louise Smith

After a week of using this I have noticed the black heads on my nose and chin slowly disappearing. I have tried plenty of different products on these areas but none have worked quite like this.

Rosie Archard

Definitely targets big spots!

Suzanne Murphy

Gayle Rooke

I used a 2% Acid which is better and smells nicer

Laura Bagova

amazing! clears your skin perfectly and its very good for dry skin as the base is lightly oily. loving it!!! brightened complexion too.

Léa Scurti

Pretty good product! The change in my acne is not dramatic, but I have a little fewer spots and my skin definitely feels smoother and more balanced. I use it every night after my cleanser.

Rachel McGarrity



I love the list of ingredients, but unfortunately this product is not for me. It makes my skin sticky and greasy and doesn't help with my akne.

Kerry Stewart

I had to write a review about this product! I've only been using it for a week (which I think is not enough time to write a true review!) However, my shrinking black-heads say it all! What a difference, very quickly! I'm excited about this product - it works! Please note I gave also been using porebright for a month so I do not know if my results are a combination of the two but my skin looks and feels good.

Elena Cacciapuoti

I’m still testing this product. It worked when I started to use it by reducing the white heads I have into easy to squeeze black heads. Right now I see and increased quantity of spots on my skin and I don’t know if it is related to the product or the the birth control pill.

Emily Rivers

This serum is good. It's easy to apply and non-greasy which is good for under moisturiser in the day. I've noticed a difference in my skin paired with my prescribed medication. It's certainly worth a go if you're struggling with frequent break-outs. Expensive though, but I think it will last a long time.


Love this serum. I like to use it whenever I have any blemishes starting or red spots. Works really quickly for me and seems to reduce it immediately. Definitely purchasing again.


Feels fresh, rubbed into skin. Definitely skin is less inflamed.

Anya Kohler

This serum seems to have brought about a major skin purging episode for me but after two weeks of using it my skin is calming down and is definitely clearer and smoother.

Hannah Hudson

Skin feels beautiful and spots have cleared up
