Since having my baby, my skin has changed dramatically. It lost a lot of its bounce, it felt thin and I suddenly have rosacea and rough texture. I have only used the Bf serum on my face and body for a few days but from the first use my skin feels like it’s drinking in the hydration that it desperately needs. It now feels pump and hydrated. When I cleanse my face, it doesn’t feel completely stripped of its moisture anymore. The serum smells like fresh citrus. It’s very lightweight and absorbs immediately into the skin. This stuff is so natural. I licked my lips after applying to my face and there was zero chemical taste! And I love that I saw a little cell of finger lime pulp dancing in my serum when I pulled it out of the box! I have already felt a huge improvement, I can’t wait to see how it will transform over the next few weeks!

Ingredients: Finger Lime, 0.2% Sodium Benzoate

Use Bf serum for:
  • Full-body hydration
  • Full face serum
  • Reduce cellulite and dimples
  • Anti-oxidant protection from damaging free radicals
  • Reduce damage caused by long-term over-exposure to the sun

Finger Lime 100% active nutrients*

Plant-based natural vitamin C

The science
Vitamin C from a natural source increases the suppleness of skin, reduces fine lines and wrinkles, increases elasticity, inhibits melanogenesis and reduces dark circles and sunspots. The powerful active nutrient also helps combat skin damage from harmful UV rays.

Why do I need vitamin C?

  • Hydration
  • Anti-ageing
  • Skin brightening
  • Reduce sun spots, blemishes and dark circles
  • Anti-oxidant to protect from free radicals and environmental damage

The science
Tryptophan is an alpha amino acid that helps protect the skin from damaging environmental factors such as UV damage that can cause dryness and sensitivity to delicate skin cells. Tryptophan builds protein hydrolysate to lock in moisture and hydrate and strengthen skin cells deep within the dermal layer.

Why do I need tryptophan?

  • Hydration
  • Protection against free radical and environmental damage
  • Strengthen skin cells

Ferulic acid

The science
Ferulic acid is a hydroxycinnamic acid that hydrates and protects against free radical and environmental damage caused from exposure to UV rays and pollution.

Why do I need ferulic acid?

  • Significant protection from UV radiation
  • Hydration
  • Prevention of skin alterations such as sun and age spots and skin blemishes
  • Prevents early ageing

The science
Byangelicin is a flavanone that promotes anti-glycation activity. Glycation causes protein and collagen to become stiff and malformed and reverses this process. Byangelicin is also a potent anti-ageing active that reduces the onset of fine lines and wrinkles

Why do I need Byangelicin?

  • Reverse the appearance of dimples and cellulite
  • Stops the build-up of skin leading to dryness and flaking
  • Anti-ageing

*An active nutrient is a biological ingredient in the plant source that directly affects the function of the skin. All serums in the Biologi range re undiluted and contain active nutrients at 100%

How to use Bf serum:

  • After showering and when completely dry, apply one pump to each area of the body
  • Apply every second day, or as required
  • To reduce sensitivity, use twice daily on the face after cleansing before switching to Bd or Bk serum once a full Bf bottle has been completed.

  2. Sarah C

    My partner was the one who introduced me to Biologi, he had heard that the Bf serum works wonders for those with Eczema. Having suffered from Eczema since I was born and having tried everything under the sun I never believed anything would ever work for me. That is until I found the miraculous Bf serum! It has hands down saved my skin, and in turn completely boosted my self esteem. It has not only healed my eczema on my hands and face, it has also removed the redness from my face and made my skin look and feel better than ever, and better yet I hardly wear makeup anymore!

    Other products I would try would work for a week or two, and then the flare up would return even worse. The Bf serum for me has made me fall in love with my skin and there is no way I would use anything else now apart from their products. Thank you for creating something that works, something that is healing not harmful for your skin, and something that LASTS.

  3. Jade Martin

    I have been using the Bf serum for over a month now and I have found this to be the only thing that has worked on my 7 month olds eczema all over his body. The eczema on him is like he has been sunburnt and he’s forever scratching himself to the point he is bleeding and I didn’t want my baby on steroid creams. I saw this product on Today Tonight Channel 7 and honestly I thought why should I pay the $$$ if it’s not going to work, but I was so wrong! This product has helped us so much his eczema has disappeared I use it religiously and God if I miss a day/night its back again, so Thankyou from the bottom of my heart and my families for producing a product thats not full of nasties and one that actually works.

  4. Magan

    I’ve used multiple products from doctors and skin specialists over the past 26 years but nothing has worked better than the Bf serum for my eczema. Having eczema on my face is not only irritating but destroys my confidence and makes me so self conscious to go anywhere. Putting make up on to hide it makes it so much worse so I would just say no to social events. The Bf serum has turned my life around and given me so much confidence in my own skin. Thank you SO much, I will use this product forever and recommend it to people always.

  5. Sanya Cardamone

    This serum has changed my life. Being a busy mum of 2, I never really had time for a complicated skin routine until I got my hot little hands on this life changer! After years of suffering severe eczema and trying out so many different products, nothing has helped me like BF serum. I have finally found something that has worked wonders for me. It’s quick, easy and effective. I love the fact that it can also be used on the face. It’s given me a wonderful healthy glow, Thank you for creating this magic serum.

  6. Hannah Demerise

    This product was absolutely life-changing in treating and completely clearing my sever facial dermatitis/eczema. Cannot recommend this highly enough!!
    I am a sceptic about these kind of things, but my skin has never looked so good!
    These results are absolutely amazing and this is now the only skincare product I use! I now wash my face with oatmeal, and stay away from soaps, moisturisers, and foundation completely.
    I switched to using the Bd serum after feeling how much lighter it felt on my face.

  7. Jessica Crosdale

    About 2 months ago, I said to my partner, ‘I think I am going to be one of those people that will always have issues with acne as nothing has really worked.’ That same week, my friend recommended Biologi to me. I can now confirm that I do not stand by that original statement. My skin is improving every single day. I grew up with eczema and had to use steroid cream on my face so it really thinned my skin. This is why I have struggled to find the right product. The Biologi Hydrating serum is the only product that has actually improved the look and feel of my skin. I no longer get breakouts and I will forever be grateful for the team behind Biologi for literally changing my life… as dramatic as that sounds. I only use it in the morning before I put on my make up and wash my face at night time and go to sleep with no products. This is because I like my skin to just take a break. My skin still feels hydrating after washing of my make up at night. So crazy! Do yourself a favor and PURCHASE IT! Push through the initial sticky stage and minor breakouts. It is so worth it!!!

  8. Alarna Taylor

    I’ve just about finished my first bottle of Bf serum and I’ve noticed a massive difference in my skins texture & over all brightness!! I have had so many compliments on how my skin is looking which wasn’t ever usually the case! I get some dermatitis flare ups around my nose but since using this it’s not near as often !! Definitely will be repurchasing this product!!!!

  9. Sally

    Amazing! Unbelievable hydration that lasts all day with only 1-2 pumps! Seriously, any more & it’s too much! Use it daily on my body & alternating on my face with the other serums & my skin has never been better! Without a doubt, the best skin care investment I have ever made! The perfect all-rounder 👌🏻

  10. Bec Winter

    Best after sun product on the market! I’ve been using the bf serum for several weeks now and my skin has been loving it. But yesterday I got a nasty sunburn and applied the bf after a shower, 12 hours later the sunburn was almost healed. I’ve never used anything like this before. It’s the only product I’ll be putting on my babies from now on. It ticks all my boxes.

  11. Jacqui

    This product is amazing! Never before has my skin been so soft! I have really old wrinkly looking hands, and for the first time with the help of Bf they are actually looking my age! Visibly less wrinkles and so soft and smooth. Thank you!

  12. Stacey

    After having hormonal acne during pregnancy then dry irritated skin around my eye area I tried Biologi for its promise of hydration and I will never use anything else now! Amazing! I haven’t had a pimple in at least 6 months and I always wore make up – now I only wear a little under my eyes because babies – the fact you only need a tiny pump of it and that it’s as natural as u can get just makes it even more amazing! I recommend it to anyone and look forward to adding the Bd and Bk to my regime soon.

  13. Stacey

    After struggling with hormonal acne during pregnancy and then extremely dry irritated patches of skin around my sensitive eye area I tried Biologi Bf and now it is all I will EVER use on my face. I haven’t had a pimple in over 6 months and my skin is hydrated and plump and improving with each month of use. I am keen to introduce the Bd serum in the future. I have never not worn makeup and now I wear a small amount near my eyes because well babies it’s that good! And knowing it’s as natural as possible while being active and only needing the smallest amount makes this product a dream come true!

  14. sarahjane.church

    I went in very hopeful for this to work. I have suffered acne for many years, I have been on roaccutane and as a result have been left with very dry, sensitive skin along with pimples. I have tried everything (and I mean that, literally everything!). I gave it a few weeks to let it “purge” as they say but it’s now been a month and I thought it wasn’t too bad until my husband said that he’s never seen my skin as bad as it is now and that’s when I realised he was right. I have gone back to my usual products and after 2 days my skin looks better! This product sounds amazing but it’s not a miracle cure. I’m disappointed that I got suckered in to another well marketed instagram fad.

  15. Claire

    I just had a little outbreak of eczema.
    I’ve had it my whole life and, before now, thought that I would have it forever. But Bf serum healed it within two days!! I already knew it was magic as I have been using it for about two months now on my face, but to watch the skin heal so fast really reaffirmed how I feel about the product. Biologi has completely removed the anxiety and panic I used to experience along with an eczema outbreak. Even if one occurs, I know that I will be healed within days, and it gives me so much relief, allowing me to investigate the true cause of my eczema, without feeling debilitated by the symptoms. Beautiful quality, and a wonderful company that I feel happy to support! I am steadily phasing out all my other skin care and will use Biologi forever.

    This serum is transformative. The skin on my legs has life again. It is no longer blotchy and tired looking. The serum has also cleared a stubborn patch of psoriasis. It starts off sticky for the first week of application but then settles and becomes lovely and smooth. I love how it gently exfoliates as I apply it. Brilliant stuff!

  17. Stefanie

    This serum is amazing. My skin has life in it again. It no longer looks blotchy and unhealthy. The serum has also cleared a stubborn patch of psoriasis. Felt really sticky on application for a week or so but now feel soft and smooth. Brilliant!

  18. Hannah

    I recently flew from Brisbane to New York and the Bf serum worked wonders !!! It honestly gave the ultimate hydration for the duration of the long flight ! I usually dread the crepe paper feel of my skin that comes at the end of long haul flights , but not this time ! I applied it once the morning of leaving and then again at LA airport and upon leaving New York it was dewy , plump , hydrated and looked rejuvenated (HOORAY!) Love love love all the products , I cannot recommend them all enough !

  19. Jessica

    Wow this product is freaking awesome! Clears acne, diminishsnes scars & my skin glows! I highly recommended this product. I won’t ever part with it. By the way I hardly ever write reviews 😊

  20. Emma

    Biologi products are truly amazing! My skin has totally transformed from dry and blotchy to smooth, clear and firm. I used to have psoriasis around my hairline and now that has disappeared . I am now trying this product on other patches of psoriasis on my body and it has definitely taken away some inflammation.
    I love the easiness or these products and I have not used anything else since , including make up and BB creams because I simply don’t need them. The furrow between my brows has disappeared and my skin feels hydrated all the time. Thank you Biologi. ❤️❤️❤️❤️

  21. Alana Chancellor

    A hydrating bottle of beautiful-ness! Honestly! This is the second product within the biologi range that I am currently using (on my face and body) and I can’t believe how well my already ‘very healthy skin’ is responding. Again, I am referring my friends and family to this little gem and even my husband is using it now! We are both so impressed.

  22. chanidsara23

    The best skin care for eczema skin!!!
    After suffering from eczema on my face over a year. I’ve decided to try BF serum and it’s not disappointed me!!!
    It cleared up my skin within a week!! Even now I’m still having some redness and dryness on my cheek but I’m still very happy with the result😁
    You can never go wrong with BF serum💯

  23. Zayra Sabido

    Biologi Bf has restored my faith in a natural product for my son who suffers from eczema. We tried lots of products to treat and reduce his flare ups with no success. Bf was the only product that worked for him, and what I love best is that it is NATURAL.
    I have even started using it as part of my own daily skin regime and I can feel how soft and supple my skin has become.
    We are hooked on the Biologi range!

  24. Mai

    A sample of the BF serum was given to me after I got my eyebrows microbladed by my brow artist to maintain the pigment. However, my daughter had other plans and decided to use the Bf serum for her problematic teenage skin. After 4 days of using the BF serum, my daughters skin cleared up beautifully. Even her friends noticed and commented on how “glowy” her skin had become. As for my eyebrow tattoo, they maintained their pigment beautifully.

  25. Jenna

    I burnt my pregnant belly on a hot pot and have been applying the Bf serum twice a day since. It’s been 5 days and it is healing very nicely.
    I also love to use Bf on my lips!

  26. Kerrie Frizzell

    As a more mature woman I was interested to see how Biologi worked for me. I tried the eye serum and face serum to start with and found the face serum too “active” for my skin. I now use the eye serum around my eyes and the body serum on the rest of my face and décolletage and the results are AMAZING! Whenever I run into someone I haven’t seen for a while they comment on how young and fresh I’m looking and I can only put it down to these magnificent products. I also absolutely love the simplicity of use. I’ve thrown all my other skin products away – these are all I’m ever going to need or use from now on. Thank you Biologi 🙏🏼

  27. Olivia Main

    If i could only use one beauty product for the rest of my life- this would be it!!!
    As a breastfeeding mum, i make sure all of the products i use are completely natural. This can mean it is hard to find something that also has active ingredients.
    This product is so smooth and non oily- its a win win!

  28. Elizabeth

    Wow! The Bf serum is incredible!!!! I purchased it after my friend told me it was really good for sunburn. I thought it would just be like Aloe Vera gel and make the sunburn feel more comfortable. I was SO wrong! The morning after I applied it I was so shocked. It was like magic. My sunburn had completely disappeared like nothing had happened and normally if I get accidentally burnt my skin will peel a few days later and it didn’t! I’m super impressed and have been telling all my friends that spend a lot of time outside about Biologi and especially the Bf serum.

  29. pia.simone

    After switching to all completely natural skincare, make up, hair care etc nearly 4 years ago I have tried quite a few different natural skincare brands in hopes it would clear my mild acne, acne scarring, uneven skin tone and redness. All pale in comparison to Biologi. The hydration is second to none, my skin looks luminous, clear and happy finally!
    I use all 3 serums and alternate with my skins needs. Bf is excellent for a summer holiday, great to hydrate face and body after days in the sun,
    It makes skin literally glow!
    My partner commented on my skin and now steals it too!
    You guys are amazing!!

    Any chance you’ll produce a Cleanser & Exfoliant..?? 🙂

  30. lauren.heydenrych

    I brought this after having two surgery’s on my
    stomach close together this year . I wanted to see if it worked as well for my body as my face.

    Not only have my scars dramatically reduced in size and color I am now also pregnant so it’s helping to keep my stretch marks at bay. I am
    really impressed with how well it has worked to reduced my scars appearance in such a short time

  31. Kathryn

    Such a great product. Perfect for the whole family. I get a little anxious when I see the bottle getting low!
    Perfect for my children who suffer from eczema. We have not had a bad flare up since using the BF serum day and night. It acts as a fantastic protective barrier. I have spent so much money using so many different products.
    This is now the only product we need.
    So hydrating, and great for inflamed skin.
    It quickly cleared up flakey skin I had always had trouble with on my forehead.

    You will not want to stop touching your arms etc after a good exfoliation and a bf serum application. Gets rid of those annoying bumps behind the arms!

    So thankful I found Biologi, it really is a game changer.

  32. Morgan

    This is a miracle worker! It’s nearly completely cleared up my rosacea in only three weeks. I use it on my whole body. My hands and feet are no longer dry and my skin isn’t greasy in the Sydney humidity. I LOVE IT.

  33. Natalie Watts

    I absolutely love this product, I’ve been using it for 8 weeks now and my skin has dramatically changed. I was suffering from rosacea, dry skin and uneven skin tone. My redness has almost nearly gone and I am literally glowing, I 110% feel so much more comfortable in my own skin, so much so I don’t even feel the need to wear foundation. I’ve not only been using this product on face but all over my body, My skin has never looked more hydrated ! This product is an all rounder, I definitely recommend.

  34. Ashleigh

    I can’t stop obsessing over the Bf serum. I have sensitive skin and this product is the first product out there that doesn’t irritate my skin at all. It does wonders, in less than 2 weeks I can see vast improvement in my skin texture and overall radiance. A small amount goes a long way. I just love it!

  35. Sophie

    This serum is my favourite! especially over winter as I use fake tan more often which drys my legs, arms & neck out, so light and easy to put on.

  36. Shelley Mcilvride

    Sometimes you forget about how important your body is and I find this the best product for the neck and chest hydration and any sun damage. Nice and light on the skin!!

  37. Sarah Sorbello

    This is the Best all over body serum I’ve ever used, I work outdoors and it keeps my legs and arms totally hydrated and supple , it is non greasy so it doesn’t stick to my clothes or stain , it’s just Magik !

  38. Suzie

    This is my favorite serum of the trio. Not only does it moisturise and repair but all the solar keratosis on my arms and legs (and there were heaps), are coming to the surface, flaking off and now gone forever. AMAZING!
    When I’m traveling this is all I need in my skincare bag!

  39. janel

    I am in love with this product! My skin, especially on my legs feels so soft and supple, and no more dry patches. Its the only product I will use as nothing else works as well.
