These serums simplify my skincare as don’t need to use anything else and my texture has improved

Nothing special

Stella

This duo is a good concept but didn’t really help my sensitive skin. It didn’t make a noticeable difference.

    K

    It's ok and not greasy, but nothing really changed.
  3. Holy Moley!

    Stephanie

    This due is amazing. After 4 weeks of use I can see a pretty noticeable difference in my overall complexion and a definite lightening of pigmentation. Love it and will continue to use it for sure.

    verified purchaser
    I got this as my little travel buddy, of course we aren’t travelling but I love how there is only single ingredients. Really different and to support Australian made is always good. I really like this duo, hydrates my skin and will find out in some weeks if it helps any pigmentation
  5. Simplifies routine

    my

    Received a mini sample of this duo and found them perfect for travel underneath my moisturiser for day and evening - skin feels hydrated and plump however probably need to use more consistently to see noticeable results
  6. moisturizing serums

    K

    I use these day/night serums for 2 weeks, my skin is more soft and hydrate. It is a good serum that make your skin feeling not dry especially in winter,. Both serums are very sticky, after I apply the serums, wait for 5-10 mins until it is fully absorbed, then I apply the day/night cream on it. However, this product is expensive and still can't see the result on lightening dark spots & brighten o...

  8. All time favourite serums

    Mel

    The quality and pure it’s of these serums are amazing. A little goes a long way so the small vials will last a long time.
    After about 2 weeks of using the radiance duo I really noticed my skin looking more plump and radiant. I had a nice glow and for the first time my skin was free of redness and I could go without make up. Pores appeared smaller and fine lines diminished

  10. A very bad experience!

    Olive

    I was lucky enough to receive two samples of this Radiance duo as a gift with purchase (thank goodness for the samples!) and had high expectations, as one would for any product with the word 'radiance' in it. Unfortunately for me, my skin reacted adversely to this duo, exceeding the usual and expected purge that can occur with active skincare (bear in mind that my skin is used to, and can tolerate...

  11. Moisturising

    Dee

    Recieved this pair as a sample or I never would have heard of the brand or tried it. Was pleasantly surprised with the results. Natural pleasant smell and very moisturizing for winter.
    Initial use has a bit of a sting. But you don't notice it anymore after a few days.
  12. Perfect for those who want to simplify their routine

    Kat

    I use these bad boys in alternate nights with the BF serum and I finish with the Rose hip. Damn once you get through that little purge your skin is amazing. Plus you know exactly what’s in your products (aka single. Ingredients)
    Perfect for travel, I know we aren’t doing much of that atm but it’s a great simple routine to follow
  13. A treat for your skin

    jj

    Used this duo for a little while and definitely noticed that my skin was softer and less dull-looking, however not sure if it is a staple or necessary for EVERYONE. It is a liquid-y texture, but feels a bit oily on the skin, and there's a noticeable scent which honestly I don't mind at all. The full size is definitely pricey for how much you get, but it honestly lasts pretty long as you don't need...

  14. Healthy Skin

    Sam

    Gives your skin a beautiful healthy glow, but do be careful of a purge period. I found that slowly introducing their products into my routine helped quite a bit as their products are quite potent!
  15. Love!

    Jay

    I’ve been using these with my gua sha as they give it lots of slip and my skin feels so soft and less textured. Just be careful as the product squirts out really fast and you obviously don’t want to waste it at this price point
  16. Love this

    Rich

    These vitamin c serums have an oily feel and are to be used alone which simplifies the skincare routine, my skin texture has improved
  17. Disappointed :(

    Christine

    I really REALLY wanted to love this. The thought of not needing all my serums and moisturisers, and instead simplifying to a day and evening serum was tantalising...however I started using them and it just didn't work for me. I found them both very sticky and with a strange smell that was off-putting. I also found the day serum left me quite shiny in the T-zone by the afternoon. Sounds like it wor...

  18. Nourishing

    Jen

    I have a mini of this and the instructions say to start with the morning serum only so I used it yesterday, it goes on like an oil and by the evening my skin still felt so nourished that I just skipped my evening routine as I figured these are so expensive anyway I’ll just leave it on. Woke up today with super soft skin!
  19. Travel friendly.

    Natasha

    I bought these to take away with me on a holiday as i didn't want to take lots of serums with me. Not only is it handy to just only have one day and one night serum that provides hydration and targets concerns, but the bottles are sturdy plastic with pump dispensers so they are great for travel.
  20. Lovely duo, skincare made easy.

    sarah

    I received a sample product of this duo as have always been curious about more natural/ vegan skincare. I have to say i was impressed with how luminous these products made my skin feel. The texture is more of an oily feel but spreads nice and sits well under makeup. I usually have breakouts with Vit C, but skin loved the morning serum and the night serum left my skin feeling soft as. Happy and lov...

  21. Radiant skin!

    M

    I received samples of each of these products and have been using them religiously every morning and night since then. They've definitely given my skin a more radiant and fresh, glowy appearance. I'm also happy with the way they've lightened dark spots on my face. They are a little pricey for the amount you receive, but I found that a little does go a long way with these products.
  22. Simple & Easy (but vitamin c is complicated)

    Sal

    Friend got me on to Biologi and i bought this on sale. Love that its made in Australia!

    Btq's brightening effects are not mind blowing, but still very nice. Doesn't feel dry, didn't break me out, suits my skin well

    Couple caveats tho:

    1. Biologi talk up the high concentration of "pure, natural" fruit extract -- but we don't know the % of vitamin c. This is im...

  23. Great concept

    Amelia

    Love the concept of having a simple, straightforward morning/evening routine. However the morning one did irritate my skin so I stopped using this treatment. It's great on my décolletage though.
  24. samples were great

    ya

    I tried samples of these and found they were really nice and hydrating and lasted me a long time. The biologi packaging is also so sleek and minimal on my vanity. I can't say I noticed a lot of glow from the vitamin C in this product, perhaps longer term use would work better
  25. Amazing results!

    Jayde

    I received a sample via adore and I decided i would follow the instructions and applications to see if it worked and I have to say I was a non-believer. I am not a person who generally has a skin routine apart from exfoliating and washing. I was amazed at the softness or my skin, the clearer my skin become in 3-4weeks and the pigmentation of acne scars and dark circles minimising before my eyes. <...

    I don’t know where this duo has been all my life
    I received a trail from adore beauty and now this will be my regular serum duo
    The vials are small but u only need a very small amount to cover the entire face
    I have seen improvement in pigmentation and fine lines and old acne scars are lighter
  27. Simply Gorgeous

    Bec

    This is honestly a pretty Mariah product! My skin feels really hydrated and super soft, and I love the simplicity of only having one product to use. It lasts a long time and it feels like really good value for a high-quality product. Definitely worth the investment.
  28. Light and effective

    Emmajane

    Received a deluxe sized sample with my last adore order. I have previously used both the bf and the bk. Was really impressed by the bq - it’s really light on the skin and I would purchase this duo in the future. - you really only need to use a pump, don’t be tempted to use more.
  29. Wow!

    Jess

    I received this as a sample but I am impressed after using for just one week! My skin is brighter and feels softer too. I love that there is a morning and night bottle - makes it super easy to use. It's a bit expensive for me personally but for those who don't mind paying a bit more, this is a good product.
  30. Glowy skin

    Prabhjot

    Provides a beautiful glow to the skin and my skin appears more healthier. It is also non-greasy. I received a sample of this.
  31. Excellent

    Tulmi

    I received mine as a sample and I’m so happy with the results after just one week!! My acne scars are definitely fading and my skin looks good. I will buy the full version!!
  32. Not bad

    Dhanoa

    I received this as a free gift. Very lightweight and a little goes a long way but I didn't like the instructions where evening serum is to be used after a week because that way I'd run out of morning serum quickly and they don't sell the morning serum by itself, it just doesn't make sense in my opinion. As for the results, it is hydrating and doesn't cause any breakouts.
  33. My fave duo

    Jade

    Even though the whole point of Biologi Is to simplify skin care I think if you psychologically need a “night” product, use this duo to put your mind at ease.
  34. Good

    Av

    I received this as a free gift and have been using this for about three weeks and still only half through. A little goes a long way and it feels very nice on the skin.
  35. Lovely serums

    H

    I received these as a free sample. Impressed by how far a little product goes. I have been using for two weeks and can definitely see the pigmentation on my face lightening. The product hasn't caused me to breakout either. Will probably purchase the full size after the sample is finished.
  36. Evening Serum

    Gibs

    A very luxurious evening serum. I like that it is natural.
  37. Morning serum

    Jag

    I like that this serum is natural. I received it as a sample. I like that it has a matching evening serum.
  38. Wow!!!

    CL

    This serum is absolutely beautiful. I received mine as a sample and I am totally amazed . It soaks right into my skin leaving it well hydrated . Not sticky . High quality and well worth the money . My skin glows with radiance after using these products.

  41. Nice serums

    Lydia

    Good value and the eye serum is amazing for dry skin and eczema around the eyes and mouth. Both are super nourishing but it’s so expensive for long term use.

    Maybe organic long term is better, but for the price, I’ll stick to Skinceuticals and Medik8 etc.
  42. Nectar For Your Skin

    Lucinda

    I purchased Biologi after hearing really great things from friends and it did not disappoint. I'm a lover of clean skincare and was attracted to the simple ingredients. Definitely lives up to the hype.

    Both serums are so impactful straight away I noticed my skin looked plump and radiant. I was surprised how long 15ml lasted (about 3 months) using twice a day.

  43. It's very natural

    Kelly

    Received it as GWP. At first, I only used morning serum, which was really comfortable. According to the instructions, I will start using night serum next week. At present, the skin is tolerant to the morning serum, and the skin has been brightened.
  44. Natural Aussie goodness

    Sammmmy

    I bought this for my mum who is not really into skincare. I was sold on the fact that it’s fuss free so I thought it worth giving it a go. Mum was OBSESSED. She made me try it too and I can’t look back. Aussie made and natural, what more could you want?
  45. Amazing

    ton

    This duo really helped to fade my acne scars and gave me a nice glowy complexion in the 3 weeks since i started using it, however it is very pricey.
  46. Time poor? Overwhelmed with choice? Want that glowy, dewy look? Biologi’s got you!

    Veronica

    I’m a skincare junkie, and very rarely stick to a single brand (I want to try EVERYTHING!) but I’ve repurchased the Biologi Radiance Duo twice now. I’ve also resisted the urge to use anything else with it (besides SPF). My skin has been super clear and radiant.. and I’m eating all the chocolate during isolation so it has no business looking so good!


  47. Only Products I need!

    Courtney- Adore Beauty Staff

    I am someone who loves to see results right away and I don't like using a lot of products on my skin. After just a week of using the morning and night serums I have noticed a HUGE difference! These serums help my moisturiser hydrate and sink into my skin better, they have brightened my complexion and for my skin type there is no need for other serums to be added into my regime!
  48. Great duo

    CSH

    I have been using both serums for a few weeks, the texture takes a bit to get used to it does feel like thin hunny but I have notice my skin looks fresh and radiant since I have been using. I love how you have one morning and one night serum it’s super easy I can’t wait to try the other products in this range.
  49. Beautiful Serums

    Kate

    I really did like these two serums, both felt beautiful on the skin. I haven't repurchased though as I'm not sure they made much of a difference to my skin. I'm still on the hunt for my perfect serum, although I may repurchase again to give these another chance.
  50. Game changer!

    Marz

    When I first heard about Biologi on the podcast the thought of ditching all my serums, masks and moisturiser was appealing but also filled me with anxiety. My skin care routine was getting increasingly complicated and not really delivering results, so after hearing Hannah rave about it I decided not to reorder my usuals and give it a try. As someone with dry skin I was sceptical that I wouldn't ne...

Always being left with a dewy, hydrated glow. So many complement...

    I was looking for a natural product that still contained a high amount of actives and came across this. And holy it is amazing! I was so sceptical about not using moisturiser after as I have very dry, dull, pigmented skin but since I got these my skin has been soft, glowing and so hydrated!

    Briony

    This serum has really reduced a lot of redness and unevenness in my skin, I love how simply the regime is with this product all i have to do is cleanse and apply this morning and night. The key for me way consistency and sticking to a regime. My skin is now much more even and i have that fresh glow back.

    Lauren

    I am never letting this product run out. I've noticed HUGE changes in my skin. Reduction in acne scarring, reduction of redness and just a smoothness that I've never had before.
    It does take a while to work, I got almost to the end of my first bottles before I started noticing a huge change. However, the wait is worth it.
  69. Did nothing for me

    Ourania

    I’ve been using this for 2 months now and haven’t noticed any real improvement in my skin. The marketing promised reduction in redness and the appearance of fine lines. I saw neither. Overpriced for no results. You’d be better off with products from The Ordinary.
