Reduces spot redness and size

Cat Lennon

I have cystic acne prone skin and need to use things that contain salicylic and other acids. I had a lot of clogged pores and a lot of spots under the surface and when I started using this my face purged for around 3 weeks. I could tell it was a Purge and not a reaction as lots and lots of little spots was coming to surface very quickly. After 3 weeks The Purge stopped and my skin was quite a lot clearer. I will never have perfect skin but I swear by this and their salicylic acid face cleanser.

Huge improvement in my skin from using this. Have had a few problem areas that really got me down but the serum has really helped.

Lynne sawyer

I'm very happy with this product, I've had other salicylic acids before but they have been very harsh and drying, this one hasn't been like that, cause its full of other moisturising ingredients.


Very gentle and has helped calm my skin. I haven't had it long enough to know if there's a good long term effect.

I only use this once a day (at night), and have been using it for just under 2 weeks. I have a real problem with those 'invisible' comedones my chin - the ones where you can't really see them with the naked eye, but when scrutinising yourself in a magnifying mirror and manipulating your skin, you really see that there's a lot there. I've tried so much and resorted to prescribed face gel which has had a good effect. However, it also makes my face dry and itcy and is full of other stuff. So, I am now trying to rely on skincare products to help. I hope that the full routine with the products I have from FaceTheory will help, especially this serum - I dab it on my cheeks and focus it more intensively on my chin. It hasn't removed my comedones entirely but my skin looks and feels clearer and brighter and smoother. I hope that with more extended use it will start to have an impact on those comedones.

This is amazing, I use it over night and after one usethe size of my spots are reduced massively.

My skin seems to have gotten worse, I’m not sure if it’s due to the fact this is a fairly oily ‘serum’ but I filled in the questionnaire and mentioned what my skin type was and this was recommended. Was between buying this and the exfoliater and I chose this as it was meant to be stronger and was more expensive so I assumed better but my skins still spotty if not spottier. It could just be because of my skin type though. Disappointed as I know that this brand has helped my skin in the past.

Hi April Sorry you didn't get the results you wanted with this - you may want to read about skin purging to see if this may be an issue. Please contact us for a refund or replacement. Jamie


I have been using this product for about 2 weeks to help with pregnancy acne. I have just begun to notice my spots looking less raised and the redness around them starting to reduce. Obviously hoping that in a few more weeks I’ll notice more of a difference.

Alice Megan Evans

Since getting this about 3 weeks ago I have noticed a big difference in how many spots and how big they are and I am impressed, even though they aren’t completely gone they are much more manageable, even around that tone of the month. I have used other bha serums before but no of them has worked as well as this one, used in conjunction with the cera c toner and pore brightening serum my skin hasn’t looked this good in a very long time. Highly recommend especially at this price

YAS!!! Hello, saviour product! So I am using this product with their clarifying cleanser. I needed this product because of my office environment- it's so humid and it's really just not playing nice with my skin. I wear this serum every day, under my moisturizer, and under my make-up. It doesnt sting, it doesnt dry out, and it's weightless. Love this product.

Brilliant product. Has really helped my skin, reduced spots and doesn't feel drying at all. I use it every day.


I haven’t noticed a huge difference in my skin since using this serum, although it does seem to have smoothed my skin out a little bit

Ela Chapman

My first one sent was faulty but luckily i got sent a new one that works fine for free within two days! I haven't used it long enough to notice a massive change in my skin but it's already helping with redness and I've had no reactions even though my skin is super sensitive


This product is magical. I have been only using it for 2-3 weeks and there is huge improvement in my skin - the heavy acne is almost gone and its getting better every day. I recommend this product 100%. I just ordered my second bottle as I want to keep using it. Amazing!

Sarah Potter

Easy to use and definitely seems to be helping with blocked pores and blackheads on my chin, great product, would recommend!

Chaitra Laxmisha

I wanted a 2% Salicylic Acid solution to help with my acne (they are small and bumpy and sometimes the really big zits which are painful and with pus) The solution works well for the big zits but most of the other acne creams do as well. I really want a solution that can help me get even skin. I wouldn't say this is totally bad - but did not do what I hoped it'd do.

Evelina Augyte

Really good product.

Kristine Berneva

Haven't seen big difference, haven't been using it for long enough. But I can see an improvement.


I didn't want to leave a review too early on but after a few weeks of using this product, I am just as impressed as I was within the first week of using it! The complexion of my skin is more toned and consistent and the texture is smoother, I have never used anything quite as effective as it and can see myself using it for a long time!

Denise Stolt

Amazing! Since a year back back I have started to get some acne under my chin and on my cheeks. I haven’t been able to do anything about it, and it started to make me sad, as I was not used to it. The BHA exfoliating serum definitely does the trick!! Will buy again


I waited to write a review until I'd been using the serum for almost 3 months - and I can honestly say I absolutely love it. I have acne on my cheeks and jawline and this has totally cleared up the acne/little bumps on my cheeks - I didn't start using anything else at the same time. Since then I've been having a salicylic acid peel every month and that has also helped, as has starting a retinol every night. I use the BHA serum underneath my day moisturiser/SPF and it doesn't clump. I still have half a bottle left so it's very reasonably priced for the amount you get. The pH of the product is also within effective ranges. I'm amazed more people don't know about Face Theory! The squalane is very moisturising (and non-pore clogging) so it doesn't dry out the skin, and the green tea also helps to reduce oiliness.

My sons skin has improved so much - fantastic

Helen Morris

Nice chemical exfoliator. BHA / salicylic acid works best on oily parts of the skin and is good at clearing clogs, blackheads etc. and is anti-inflammatory. It's doing good on my nose pores, they look a lot better! Make sure you use a good sunscreen while using acids, and for at least a week afterwards (you should wear it anyway, right?)


I was really suffering with spotty, bumpy congested skin and using this under my moisturiser has really helped my skin be smooth again.


This stuff is awesome - gentle on your skin but very effective. Highly recommend and will be using it regularly


My facial complexion become smoother and brighter in about a week. Excellent product
