Struggling with persistent acne, rosacea redness, post-acne marks or uneven pigmentation? Our 10% azelaic acid serum offers a dermatologist-favoured, science-backed solution in one gentle formula. Azelaic acid — a naturally occurring dicarboxylic acid — stands out for its versatility: it tackles multiple concerns simultaneously while remaining kind to sensitive and reactive skin types. At 10%, this concentration delivers clinically supported results for blemishes, inflammation, discolouration and texture without the irritation often seen with stronger actives.
What does azelaic acid serum do for skin?
Azelaic acid targets pigmentation, redness and breakouts by calming inflammation and evening out skin tone over time. It works on both acne-prone and sensitive skin, making it one of the few actives suited to both concerns at once. Results build gradually with consistent use, usually over several weeks.
Why 10% Azelaic Acid Is a Game-Changer for Problem Skin
Azelaic acid works through several key mechanisms: it has antibacterial properties to combat acne-causing bacteria, anti-inflammatory effects to calm redness and irritation, and tyrosinase-inhibiting action to reduce melanin production and fade hyperpigmentation. At 10% — a popular and effective over-the-counter strength — it visibly:
Clears and prevents acne by unclogging pores and reducing breakouts
Soothes rosacea symptoms, including persistent redness and sensitivity
Fades post-inflammatory hyperpigmentation, dark spots, acne scars and melasma
Evens skin tone and improves overall radiance
Gently refines texture and minimises congestion without over-drying
Dermatological research and user experiences highlight that 10% azelaic acid provides noticeable improvements in clarity, calm and evenness within 4–12 weeks of consistent use. It is especially valued for being pregnancy-safe (consult a doctor), non-photosensitising and compatible with most routines — making it a staple for acne-prone, rosacea-prone or pigmentation-focused skincare in the UK.
The lightweight, fast-absorbing serum texture makes it easy to layer morning and night, ideal for all skin types — especially sensitive, combination or oily.

How to use
How to use
After cleansing, apply 2–3 drops to face and neck. Gently pat in until absorbed, then follow with moisturiser. Use AM and/or PM — many find it excellent in the morning under SPF or at night for repair. Start with every other day if new to azelaic acid, then build to daily use. Always apply broad-spectrum SPF 30+ in the daytime. It layers well with niacinamide, hyaluronic acid or gentle moisturisers; avoid combining with strong retinoids or high-strength acids initially.

My skincare has just got better, i love the glow on my skin. I’ve seen changes on my skin, its been 2 weeks using this serum & already my skin looks great
My fighter for dark spots. I used together with vitamin c. And I’m on oral oratane. My skin has never been better.
I need fundamentals to make a higher percentage azelaic acid
My go to serum, absolutely amazing
A very good product, leaves the skin feeling lively and fresh, I love it.
Obsessed! It’s so gentle.
My skin texture is so smooth and my hormonal breakouts around my period have calmed down so much!
This serum is really a must have.🤞🏽
Amazing product
Gentle and effective in removing dark marks.
The product is good I have not had any issues using it
The product itself works very well, however...about a month after opening, it started to go rancid. For a few months I thought it was fine, until it developed an alcoholic smell and I realised it was a water serum. I held the bottle to the light and you could see colonies of bacteria loving life in there- I did not ever touch the dropper to my face and it was never kept in a bathroom and I always closed it tight, so unless you are going to use 30ml in 1 month then fine but otherwise I would pass. I have nothing against water serums, but the stability of this one is, in my experience, is non-existant.
I have mixed feelings about this girly. Some nights it gives an excellent glow in the morning and some nights it gives me really dull skin. But my hypothesis is that my skin isn't taking well to the Tranexamic acid because a couple of weeks ago I used the txa and retinol serum which gave me the most awful rash. I stopped everything and just used ceramide moisturizer and now I've started using this product again and the rash is back just less noticeable.
Absolutely love this product
Good product
I know they say it takes time to see results but I could FEEL a difference in my skin from the second or third use. About a week after, I went on holiday up in the mountains and my skin took a pounding (obviously I forgot to use my serum). Now Im back, using it again and its incredible. Had a bit of a acne but literally only 3 spots (which happens, as explained in the letter I got with the product 💙)
This really is an amazing product and at such a brilliant price - well worth it!! I will be ordering again!
This has been my fighter from last year for my monthly hormonal breakouts. The pimples no longer leave that much of the hyperpigmentation and its very gentle on the skin
Feels smooth on skin, dark spots are getting clearer
I've been using the serum for a week, and my skin has more break outs than before. It hasn't calmed my skin down at all.
Love it down!!!!
Amazing product, I’m on my third bottle, I started seeing real results with the first bottle. My dark marks are fading I don’t breakout as bad as I used to, my skin looks healthy and hydrated.
I can't even begin to describe what this has done for my skin. I've suffered with severe acne for more than half my life. My face looked rotten (no exaggeration). Using this product for four months now consistently morning and evening and my skin is close to glass skin besides the holes (acne scarring).
Guys!!!!!!
Where do I even start, my skin was breaking out so badly. I had giant pimples on my forehead. After 34 years of clear clean skin. I was on the brinkof depression.
My friends little cousin took one look at me and said, I was you a year ago. I tried Fundamentals. I looked at her and thought no freakin way. She has beautiful skin. But the pictures she showed me.
I was like what the hell, I've tried everything else I might as well.
And I tell you what!!!!!!! I am a new person. I still have a pimple here and there. But man. My skin. My confidence.
I am so so glad I gave this a try, I'm now also using the toner,ssunscreen.AAnd I really like the direction my skin is taking. It's almost a year now. And I can't say thank you enough you guys!!!! ❤️😊🤭
Lightweight and gives me a nice glow.
This serum has kept my acne at bay when no other skincare ingredients have. Already on my third bottle and can never say no to a fourth!!
I am so happy with the product it helped reduce redness and added to my pimples clearing sooner with very little scaring.
Azelaic acid is the only thing that has consistently worked at controlling my acne and hyperpigmentation. Coupled with tranexamic acid and you have a powerful duo that just works.
Love the serum, I had to stop using it daily to every other day but this was expected when you introduce a new product to your skin. ima keep at it though :)
I love this product.
Been using it for ober a year. .. works great
Great product
The azelaic acid serum is amazing its not drying and it helps with breakouts havent seen a difference with hyperpigmentation but it is promising as ive only been using it for a month. ❤️
I love it. .it's absolutely stunning for my skin! It helped alot with reducing redness and for my inflamed skin.
I got this in a sample size and it still made a difference, my skin is prone to break outs but, along with other products that i got from Fundamentals my breakouts have reduced significantly.
The best, I had a few pimples pop up in the 1st week and I panicked but they're slowly going away, I'm more brighter now, the black spots are slowly fading and skin is so plump. .. .
If suffer from Rocacea and find Azelaic Acid has helped to clear my face from a lot of swollen red spots. It is still there but much less
