    Absolutely in love with this product! I have never really found a skincare product/regime that has worked for me enough to use long term. I have always used different products and brands and never really stuck with anything in the contstant search for results. This serum is so incredibly hydrating! I have not needed to moisturise (something I usually need to do religiously!) and it has greatly improved the texture and luminosity of my skin after just a few weeks. Cannot wait to try the entire range!

    Bk makes me wake up feeling like I don’t need to put on make-up, it has hydrated my eye area and stopped me getting milia, those hard white dots, around my eyes. I use this on my face at night too which makes me super hydrated and I no longer need to use any form of moisturiser. I also always put a dab across a neck scar from a recent surgery – it’s softening the scar tissue for that too!

    Bk the little pocket rock that has not only dealt a heavy blow to the wrinkles around my eyes but those around my mouth, and what blows me away most is how Bk deals with sun damage! Kissing it goodbye!

    To finally find an eye serum that is giving me the results of crows feet lines fading is a Godsend , this serum keeps my face still looking fresh

    This is by far one of my favourite products. I had pigmentation under my eye that couldn’t be treated with laser and this has totally reduced the appearance of it. LOVE IT!

    I have generous smiles lines around my eyes from doing a lot of it. At 64 years I accepted that. Then started using Bk after a friend suggested I just “try it” and immediately the lines softened. Then spread Bk to the brow lines and they too diminished. Using Bk around the mouth now. You only need a drop as it spreads easily. A bottle lasts me 3 months. Try it too. And keep smiling.

    I absolutely love this product. My fine lines are reducing and my skin is so hydrated and smooth. I love the fact that it is 100% organic and natural. Thanks Biologi

    Bk is an amazing product!
    I don’t know how I survived before I discovered this little beauty! I’ve never found a product to target my eye area which I actually received results from, from cheap to expensive, most products with the word eye on the packaging started to make me feel it was all a gimmick!
    Until I tried Bk! Confidence in a bottle, I could feel the difference it had on my skin! AND see it my friends were also commenting and saying something was different! I looked like I was glowing!

    They say “less is more” –
    and in Biologi’s case, this is outstandingly true.

    Firstly, you need to know that I am a self-confessed skincare ‘junkie’ who has been on a consistent (ever hopeful) search for that elusive ‘unicorn’ of a product:

    ie: Something that is so 100% natural (that you could eat it) – but that also actually WORKS for someone in their mid 40’s whose skin is temperamental (to say the least) and has an unruly mind of its own.

    I mean, I finally got rid of Pimples… only to discover my first Wrinkle (who then invited MORE to the party) … then BOTH usurpers decided to hang out together – and invite Pigmentation into the mix!

    Awesome (not).

    Finding products to address ALL my issues meant a LOT of (expensive) trial and error and the endless ‘layering’ of many products (PLUS precious TIME).

    Then, finally finding a results-producing routine – only to have life (and the weather) change (slightly) and woohoo all bets are off.

    Honestly – my skin is like a rebellious teenager who will ALWAYS act up when I’m going somewhere important. Sigh.

    I had resigned myself to looking ancient one day with biscuit dry skin and discolouration (cleverly concealed) to oily teenage breakout skin the next.
    double sigh.

    I was also BORED hearing about what isn’t possible in the skincare world and about preservatives and additives (etc) ALWAYS being necessary (blah blah blah – yawn)

    Well, thank goodness Ross M, didn’t take any notice of this either 😉

    Innovation in any field excites me – but in the natural skincare world …? Well, Biologi had ME at ‘stable natural vitamin C extract’ (which has always had that ‘impossible’ word attached to it)
    *(pssst… That white Ascorbic acid powder isn’t a ‘true’ and whole vitamin C – and this is proven when you realise that it can’t cure anyone of scurvy – anyway I digress… 😉

    So… ever the hopeful… It was with great interest (but no expectations) that I embarked upon my Biologi journey.

    I’ve been trialling Bk (around eyes) for about 6 weeks (along with the rest of Biologi’s Australian native skincare family). and am about to embark on the night-time routine.

    My verdict so far?

    Simple – Yep … I 100% agree with what everyone else on the reviews has already said.

    I also don’t have to worry about any synthetic anythings being absorbed into my PEA brain (ha) and causing long or short-term issues (wink).

    So there you have it – Less is more:

    LESS time, fuss, steps, confusion, allergy concerns etc
    MORE results, consistent and stable delicate eye skin balance, regenerative anti-aging powers – naturally.

    … and the BEST part of all … ?

    A natural product that really and truly works with ZERO toxins = Peace of mind.

    x x x x x (five-star kisses from me)

    WARNING! THIS IS A GAME CHANGER!!!!!!!! I’m telling you, if you don’t want to live with the same problem skin you are right now, you NEED BK! I’m a skeptic, and after using Bk on my entire face overnight, I was sold! This is by far the best product I have ever used. And it’s all I use! Night time I use Bk, day time I use Bd. I wash my face and then these are the only two products I use. My husband is low key stoked about all the extra bathroom bench space by the way. My face has a much more even skin tone all over, it is always hydrated (even now in the windy cold Winter), I rarely have a breakout anymore, it feels more plump and looks younger. The best bit is the compliments when other people notice the difference! Personally I’d like to keep it to myself and be the only one looking younger…. but this game changer is making HUGE disruptions to the beauty industry, and you were going to find out about it anyway, so I thought I’d share my opinion of this liquid gold! Do yourself a favour 😉

    A saviour in a bottle! Earlier this winter the skin around my eyes was dry, irritated and inflamed. After just a few days of using the Bk serum I noticed an amazing improvement. 2 months on, not only is the skin around my eyes soft, hydrated and happy, my fine lines from dehydration have disappeared! I also pop this on my lips under my SPF lip balm and it keeps them hydrated and plump!

    I swear once I started using the Bk serum my skin has become so plump and my pores look like they’re disappearing. I have really enjoyed this new addition to my skincare routine. My skin has become softer/healthier and has given me a beautiful glow..Great for sensitive skin to 😊

    If your looking for a flawless, youthful appearance the Bk serum is for you!

    Having previously struggled with dryness and flaking with other actives such retinol, Bk has been a saviour. I use Bk daily around my eyes and all over my face at least once a week and my skin is always glowing the next day. A must for any skin care routine.

    Since starting Bk at night I can honestly say my skin has never felt better! my pores have diminished and my skin feels so hydrated and healthy. I cant imagine going back to other products now, this and Bd is all I need.. which is a big call coming from someone with a skincare addiction like mine. Once you try it and see the changes occur in your skin, you will be hooked on that glowy and plump skin feeling!

    So pleased to have come across this amazing product with age and sun the lines around the eyes were showing, not great! Now I can see a difference the lines have softened and skin feels really hydrated. After wasting lots of money on products over the years, what this has achieved in a very short time is amazing! Used to hate doing morning/evening routine but now I love it! Could go on about these products but I suggest you try them for yourself. Very happy customer 💕

    I don’t have very deep lines around my eyes, but as I’m getting older (now mid 30s) my eye area was starting to look a bit more dehydrated. Makeup was starting sit in the fine lines around my eyes. I don’t have this problem anymore! Since using this serum my eye area is so plump and hydrated and now I have barely any signs of noticeable aging around my eyes. My makeup looks much better too 🙂 thanks Biologi ❤️

    Surprisingly I have found this product to be most beneficial on cystic acne (as well as a great hydrating serum)! I apply this serum to my entire face under makeup for work and then on a clean face before bed and have found that almost instantly it starts to reduce inflammation, redness, size etc. I don’t have any dry skin or patchy areas like other zip zapping medications after use. Possibly I believe this serum is even helping to reduce the surface scars caused by cystic acne and at 32 years of age that is fantastic!

    Love it.

    I wasn’t sure if I really needed this product when I first started using biologi as I don’t really have any issues around or under my eyes BUT prevention is key .

    I have notice a difference in how dark the skin was under my eyes and I also use this over my whole face at night when my skin needs a little extra boost
