Gallic acid

The science
Gallic acid is a phenolic acid that works as a potent anti-oxidant, reduces DNA damage, inhibits melanogenesis and improves inflammatory skin disorders.

Why do I need gallic acid?

  • Anti-ageing
  • Reduce sun spots and under eye dark circles
  • Anti-oxidant to protect from free radicals and environmental damage
Tartaric acid

The science
Tartaric acid is a natural fruit acid that stimulates cell growth to modulate skin barrier function. Further, tartaric acid clears blocked pores to reduce the impact of acne and reduces coloured pigmentation allowing even skin colour

Why do I need tartaric acid?

  • Create a barrier against environmental damage
  • Clear blocked pores
  • Reduce redness
  • Reduce dark under-eye circles
  • Reduce sunspots


The science
Anthocyanin is a flavonoid that reduces DNA damage, improves mitochondrial functionality, provides protection from UV radiation and promotes new cell growth for a bright, even complexion.

Why do I need anthocyanin?

  • Anti-ageing
  • Restore skin damaged by free radicals
  • Hydration
  • Reduce sunspots
  • Bright, luminous complexion

The science
Quercetin is a flavonoid that reduces inflammation to help reduce the redness caused by sensitive skin and skin complaints such as acne. Quercetin also provides powerful antioxidant protection against damaging free radicals.

Why do I need quercetin?

  • Strengthen skin’s protective barrier to defend against environmental damage
  • Helps recover against overexposure to the sun
  • Reduce redness and inflammation caused by acne and breakouts

Frequently Asked Questions

Bd serum can reduce inflammation and redness associated with acne and can clear pores to lessen the chances and severity of breakouts. There is no topical cure for acne, the causes must be addressed internally (hormone imbalance, food intolerance for example) to cure the condition.
Bd serum can be applied as often as your skin needs hydrating. Once a day in the morning may be enough, or you might like to keep it in your bag to apply throughout the day (particularly when travelling).
Absolutely! Bd serum is single plant extract of Davidson plum free from synthetic activating agents, emulsifiers and irritating fragrance that can sensitise delicate newborn skin. Bd serum is so pure you can drink it making it one of the safest skincare products for babies on the market.
Yes! Bd serum contains the active nutrient anthocyanin which helps restore damaged skin and repair damage to connective tissue. Use Bd on your scars to reduce redness but remember that the sooner you apply after damaging skin cells, the better the chance of making a full recovery.

    I absolutely LOVE this product! My face is quite dry and I get psoriasis pretty bad through my eyebrows and nose. After only 2 applications over 4 days I felt a big difference in the softness of my skin and my psoriasis has settled down to practically non existent! I will definitely keep using this product.

    This product has changed my skin. I now use it religiously morning and evening. I am getting so many comments on how good my skin looks. Living in the tropics as well with high humidity can also be tricky to find the right skincare. I use my Sukim Cleanser followed by my Biologi face serum. I cannot recommend this product highly enough !!!

    I absolutely love the convenience and effectiveness of this Bd serum. It’s so quick to apply and the fast absorption helps to get on with my day sooner. I also appreciate how no further moisturisers are needed so my skin no longer feels suffocated in this QLD humidity ! In conjunction with the Bf and Bk serums, my skin couldn’t be happier. Thanks, Biologi 🙂

    This is the first face product that I’ve genuinely seen a marked difference with. My skin is more bouncy, clearer and far more even in tone. I’ve literally had multiple people tell me I’m ‘glowing’ since I started using Bd, which was about four months ago. I also used to get milia, those little hard white lumps, around my eyes, and since using Biologi I haven’t had one since.

    This is honestly a one stop shop, I’m never using anything else again!

    Due to the industry I work in I have worked with many “active” based skin care ranges, I always thought I was doing my skin good but never really noticed physical changes. Once I used the BD serum consistently for 2 weeks I noticed my congestion on my forehead had reduced dramatically. I absolutely love love love this serum!!!

    All my life I’ve used moisturizing creams full of promises. Expecting the more you paid the better it must be. Don’t know if I really believed that but was concerned about ” shutting the gate after the horse had bolted” so invested! Then a friend gave me a bottle of Bd serum as a gift. Within 6 weeks age spots had faded and dry patches disappeared. The serum was so light I could wear my usual liquid foundation without feeling or seeing excessive shine. There are no gimmicks and promises, no ingredient lists, no high price tags. Gets 5 stars from me. I hope a range of tinted foundation is in the pipeline.

    I will not use anything else now! My skin used to be quite reactive and impaired until I started using the Bd face serum. It is everything and more! It has improved the condition of my skin so much! I have found my holy grail skincare product 🙂 thank you!

    Absolutely love Bd, this has evened out my skin tone and reduced acne. I was someone who would not leave the house without makeup, now feel confident enough to go out with a fresh natural face.

  14. Rated 5 out of 5


    This serum is the best product I have ever put on my face! The illuminosity and smoothness you get is unparalleled to anything I have used previously and all in one handy bottle. It has completely cleared my skin and gives me a ‘just had a facial’ glow everyday. Throw everything out and use this!! 😀

    I’m a beauty therapist by trade and I have tried everything you can think of on the skincare market and this is honestly the first product that has lived up to its claims. My skin is holding onto hydration, it’s glowy, the texture is improving and my fine lines have softened. I’ll hobestly never use anything else again. Love it.

  16. Rated 5 out of 5


    This is the best skincare product I have ever used. It cleared up very stubborn and painful eczema on my eyelids after only two uses. Nothing the doctor gave me cleared it up. My eczema hasn’t come back since I started using Bd serum about 4 months ago! It has also helped clear up my acne which I’ve been suffering with for many years. This is the only product I use besides witch hazel, cleanser, and a homemade exfoliating scrub. I even bought Bd for my husband!

    I absolutely love this product. I have gone from a very complicated skincare routine to a very simple one. My skin feels soft, hydrated and is clear. Will never go back.

    I absolutely love this serum. I use to have a extreme skincare routine, and now i don’t. My skin feels soft and hydrated. Will never go back.

    BEST serum ever! The Bd serum has completely hydrated my skin and cleared up my acne. Before using this serum I constantly had painful cystic acne on my jawline and up on my cheeks. I had tried antibiotics, vitamin a gel, another topical treatment – all prescribed by my doctor – but none of it worked. I have been blown away by the massive improvement this little gem, the Bd serum has made to my skin. I don’t even need to wear makeup anymore. I do however, wear my SPF over the top once the serum has soaked in.

    This is the first product I have used since getting serious about my skincare routine about a year ago and WOW! This product does exactly what it claims to do. It’s easily & quickly absorbed into the skin, leaves no residue yet hydrates at a deep level. The appearance of my melasma, sun spots and redness under my nose have reduced dramatically!
    I just love the way I look in the morning after using the Bd face serum the night before!

    Thanks biologi x

    I use this daily and would never go back to using diluted, non-active products daily moisturisers (except for my SPF fix). It provides the best base for my makeup – my foundation just glides on. Silicone-filled primers are thing of the past for me. My skin is clear and glowing. Thank you, Biologi!

    I’m just about finished my first bottle and about to purchase my second, I can honestly say this has been the best skincare product I’ve ever used. I usually suffer from dark circles and dull skin with frequent breakouts and since using this product of a morning and night my skin has never felt so fresh and glowing, No more dark circles or breakouts and so soft and hydrating, Highly recommend!

    I decided to try this product after hearing such amazing reviews on it. I will be honest I was very skeptical of just how hydrating it would be and I really thought I’d probably have to wear a moisturizer over top because I’m a flight attendant and am in the air for over 12 hours sometimes. Well… I was WRONG!
    This product is AMAZING! My skin is hydrated so beautifully I’m really quite shocked. My skin has a luminescence about it that is really pretty. My morning and evening routines have been more than halved. I use Bk on my eyes, Bd on my face, neck and décolletage and the body serum on my arms tummy and legs. I was using Vitamin C serum then hyaluronic acid serum then moisturizer… and the list goes on. NO MORE!
    This is it for me. In 2 weeks my skin has plumped up, is so incredibly soft, the redness has significantly gone and it’s just pretty, pretty, pretty.
    If you’ve ever looked at a celebrity on the red carpet and their skin has an amazing luminesce about it ..look no more because i get that beautiful luminescence with just Biologi serums. Yup Im pretty shocked, but these are the only skin products I will use from now on. The fact that the ingredients are so pure you could eat them is just a massive bonus.

    I’d give this more than 5 stars if I could. Never have I been happier with my skin. I’ve just started to notice fine lines and wrinkles and Bd has helped change the way I feel about my skin. I can go out without makeup on and feel confident. can honestly say i have not touched any other products since these came along and I’m a beauty junkie! first time in YEARS that my foundation goes on so smoothly without a hint of flakiness or dryness. I was sceptical at first if this would work as well as it claimed but it is hands down my fave beauty discovery ever. you will not regret this purchase take me word for it. worth ever dollar.

    Oh my goodness! Wow! I have been struggling for years with really terrible dry skin that is prone to breakouts and have tried so many different products but none of them seem to ‘cut the mustard’. And to add to this I had started getting a bit of an eczema/rash thing on my face which was beyond embarrassing! I had been battling another breakout of this for about 3 weeks when I decided to try the Bd serum…within two days it was nearly all gone! The itching had completely subsided and the redness and inflammation almost disappeared! Not only that, the rest of my skin felt the most hydrated it has ever felt! I am still within the ‘slightly sticky feeling’ period (first week of use) so can’t wait to see the further results….I feel like I have finally found “THE” product for me!

  26. Rated 5 out of 5


    How do I give this more than 5 stars!? I have struggled with my skin since I was a teen, trying everything under the sun but nothing seemed to work for very long. I am so so happy that I’ve found Biologi, I will never go back to using multiple diluted products that were getting me nowhere. My skin now looks and feels amazing, improving more every day and I have so much more confidence because of it. Thank you to all at Biologi, what you have created is genius!

    As an ex beauty therapist I am always looking for products that do what they say they’ll do. I ditched toxic skincare and makeup 3 years ago now, and Biologi is THE skincare I have been searching for. I use Bd during the day and Bf at night. I love that one product does evyrhibg you need, no need for serum and a moisturiser! My skin has never looked so good!

    Such an amazing product! I’m in my early forties and my skin hasn’t been this smooth & moist for so long. It also cleared up a persistent patch of red/irritated skin around my mouth within two weeks. Such a wonderful product, thank you!!

    BEST SKINCARE EVER! I was a bit sceptical to try this at first as I’ve spent a small fortune on skincare looking for a miracle but after reading up on it I took the plunge and I’m over the moon I did. This is the first skincare that actually does what it says. In just one day my super sensitive skin was calm and the redness in cheeks was gone. My skin has not looked this good in years and it feels amazing it’s so hydrated and it does have a glow to it. I’m so impressed by the biologi serum I’ve talked my sister into buying some for herself. This is one investment worth taking and I can’t wait to see the continued results. Thank you biologi 💕

    Hiii Biologi Serum team! Just would like to let you know that I SUPERRRRR LOVEEEEE your serum! It’s pure amazing. I’ve been using organic skincare for years, but never realize that they were so ineffective, till I tried this Biologi for just 10 days!!!

    My skin never had problem before but since I work in the commercial kitchen my skin started to show few problems (redness, blackheads, whiteheads, and sometimes small acne). BUT, after using your serum my skin is coming back to the way it usually be, and becomes better and better everyday!!! Everyone compliment how beautiful and smooth my skin is, even my husband who is usually “not really paying attention” to my skin condition LOL!!
    And I feel even more amazed since I just use it for 10 days!!! I even want to stock more of them eventhough I still have some LOL! Huge thankyou to you guys for creating such powerful amazing serum!:) xx

    I have been using Bd and Bk for several months and I immediately noticed a difference the in the hydration, texture and pirgmentation of my skin. I would highly recommend this product to anyone with hormonal acne and scarring. A little goes a long way and it really does simplify your skincare routine dramatically. Thank you Biologi for your innovative products that reallly work.

    This face serum is everything. I’ve spent a lot of money on expensive face creams that never work. I started using Biologi three months ago and my skin has never felt or looked better.

    I just want to say a big thank you!! I have been on the natural / organic skincare bandwagon for a couple of years now, but struggling with ‘post pill’ skin had been getting me down and I was almost ready to give up on natural and try ANYTHING else. Biologi was like my last resort and I am SO glad that I tried it!!!!! Within a week my skin was certainly brighter and even my beautician when doing my brows asked if I wanted concealer put on and I said “I don’t have any makeup on” and she was shocked! For the first couple weeks I did have the purging and excess oil but after that I literally did not get ONE new pimple until week 6 and then it was hormonal and not near as bad as usual. SO glad I tried this product – will definitely be buying again!

    I stopped taking the pill 4 years ago and since I was fighting with hormonal acne. I tried plenty of products and have been on natural skin care for over a year but couldn’t find anything that really works. The Bd serum felt great from the first application. It kept my face (which gets very oily) well moisturised but less oily when I wake up in the morning. I didn’t even get the breakouts when starting the product which may be because my face is already used to more natural products?! Anyways, my acne finally seems to clear up (taking the product now for about 3-4 weeks) and dark spots seem to be reducing. I’m very happy with the product, the pure ingredients, how it feels and looks on the skin and the results I’m getting! And the customer service from Biologi is amazing! Big thank you!

    I was pretty disappointed that this product didn’t live up to the 5 star rating. I honestly havent found anything special from this product, it doesnt really soak in and gets on my pillow when I go to sleep. Have not noticed a difference in my skin, and is going pretty quick for how expensive it is.

    WOW! After years of trying so many products and wasting so much money I truly believe I have hit the jackpot! Right from day 1 it felt amazing, yes I had a slight breakout but that was advised this could happen and to persevere and I did. My skin is clear and glowing like never before. I have just had a week in Vanuatu in hot sunshine every day and I would honestly say this product was amazing keeping my skin lovely and hydrated. Every day I am sure it keeps getting better. One very happy customer indeed, cannot thank you enough for this amazing product, always a nice feel good feeling when your skin looks and feels great . Very happy customer indeed 💕

    Makes my skin so dewy and healthy! I have sensitive skin, prone to rosacea and a bit of acne. If I ever do get a pimple it always leaves a mark that takes ages to fade. This serum has definitely sped up the healing process. I was worried at first that as it’s a topical exfoliant it would aggravate my rosacea and skin sensitivity, but it’s very gentle and it’s actually done the opposite and my skin is more resilient now than it was before. My skin looks really smooth and my pores are more refined. You absolutely don’t need a moisturiser with this, it’s so hydrating. I can’t say enough good things about this product ❤️

    I was so excited to use this product after seeing such good reviews. However I was disappointed when I first started using it as it caused my skin to break out. I stuck with the product for about a week before I stopped using it. I didn’t touch it for about 2 months then decided to give it another go. My skin did break out again but I stuck with it and my skin has never been so clear. I have actually stopped wearing makeup on a day to day basis. My friend even thought I was wearing makeup my skin looked that clear. So happy with this product and will be repurchasing.

    I have always struggled with my skin and it has affected my self esteem.

    I am 30 years old and my skin is prone to breakouts and tends to be oily. I have tried so many products (natural and artificial) but nothing seemed to really give me the results I wanted and quite a lot had harsh chemical ingredients that dried out my skin in certain areas of my face and left my complexion dull.

    Then I bought Bd.

    It was a struggle at first. It took my skin about 5 weeks to adjust. During that time it felt like the serum was not being absorbed into my skin properly, it made my skin feel a little more oily than usual and I had additional breakouts – all part of the purge process, but not fun.

    Hang in there. I kept using this product because it was so expensive and the FAQ section promised me results! It’s actually all true – all of these glowing reviews. This product is the best product that I have ever used.

    I have been using this product for 8 weeks now and my complexion has improved so drastically. I haven’t had a breakout in 3 weeks and my skin texture is amazing.

    The only downside to this product is that it is pricey. It does work brilliantly though. I will never be without it now ❤️

    I have been using this product for coming upto two year – I absolutely love it , from being on the pill to now coming off it and falling pregnant it has helped my skin through all those stages. I love the fact it’s the only product I have to use and I don’t have to think about it . I use the eye one on my full face also at night for more hydration when I need I have recommended this product to so many people who also love it – it’s worth every single cent and a little really does go a long way

    A friend just asked me if I had Botox…. and I haven’t, best compliment ever. Biologi is the best thing that has ever happened to my skin. Everything they say is true, it’s the best, I will never use anything else.
