INGREDIENTS

MORNING SERUM

HERO INGREDIENT: Australian Native Kakadu Plum

  • Our serums contain 99.8% Terminalia Ferdinandiana (Australian Native Kakadu Plum) Fruit Extract and the smallest percentage (0.2%) of Sodium Benzoate, a safe preservative to preserve the natural plant extracts while not compromising the results that Biologi delivers.
  • During the C.L.E.C.S.™ II extraction process distilled water and organic plant derived glycerin are used as a solvent. This enables the extraction of plant nutrients in a liquid matrix with our Bio-Key™ technology, protecting the natural actives and allowing the serum to perform on the skin just as it does in the plant. No additional water or glycerin is added to the final product.

Ingredients: Glycerin, Aqua, Terminalia Ferdinandiana Fruit Extract, Sodium Benzoate

EVENING SERUM

HERO INGREDIENT: Australian Native Quandong

PHYTO-ACTIVES

Phyto-actives are actives extracted from plants, delivered in the plants liquid matrix in a active stable form.

Phyto-actives found in Kakadu Plum extract:

  • Vitamin C - from a natural source helps to inhibit melanogenesis (the formation of unwanted pigmentation) increases skin elasticity and reduces redness and sunspots.
  • Gallic Acid - is a phenolic acid that works as a potent anti-oxidant, reduces DNA damage, inhibits melanogenesis and improves inflammatory skin disorders.
  • Ellagic Acid - Another phenolic acid, ellagic acids helps in the treatment of chronic UV exposure, reduces the potential of photoaging, inhibits melanogenesis and reduces membrane liquid peroxidation and DNA damage.

Phyto-actives found in Quandong extract:

  • 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.
  • Ferulic Acid - is a hydroxycinnamic acid that hydrates and protects against free radical and environmental damage caused from exposure to UV rays and pollution.
  • Rutin - is a flavone glycoside containing powerful antioxidant and anti-inflammatory properties essential for a clear complexion and even tone.

HOW TO USE

MORNING (lighter in colour)

  • After cleansing, apply Bk (lighter in colour) morning Serum to a clean dry skin.
  • Use one pump for face and two pumps for face and neck.
  • Apply SPF.

EVENING

  • After cleansing apply the Bqk (darker in colour) evening serum to a clean dry skin.
  • One pump to cover face and two pumps to cover face and neck.

It is common to experience potential skin adjustment when you first introduce this serum duo, therefore if you are new to Biologi serums, we recommend using the morning serum daily for the first week and then introduce the evening serum from week 2.

Dynamic duo!

The morning serum, powered by Kakadu Plum, shields against pollutants, boosts collagen production, and combats signs of aging.

Meanwhile, the evening serum harnesses the benefits of Quandong, an Australian native antioxidant, to treat pigmentation, redness, uneven tone, and lack of hydration, revealing radiant and glowing skin.

Frequently Asked Questions

I Don’t Have Pigmentation, Can I Still Use Bqk Serum?

Yes! Bqk Serum is a AM and PM duo serum system that is perfect for all skin types and conditions but also for those that want clarity and radiance. For skin concerns of pigmentation and skin discolouration this system is highly recommended due to its targeted phyto-actives and nutrients that assist and help in reducing and preventing further accelerated pigment in the skin. The synergistic blend of both Kakadu Plum and Quandong aims to keep the skin clear and bright.

I Missed The Morning Serum, Shall I Apply Both Serums At Night?

No, you must always use serums as recommended. Combining the morning and evening serum in one application may reduce the efficacy of the active ingredients and compromise results. If you miss a morning or evening application, continue the ritual as directed.

Where Do You Source Your Plants?

Kakadu plum (morning serum) is sustainably sourced from Aboriginal communities in WA & the NT.. Quandong (evening serum) is sourced from Broken Hill NSW. We have direct contact with farm owners and guarantee that all extracts are traceable from the farm to your bottle.

Do I Still Need To Use Moisturiser?

Once you introduce Biologi serums into your skincare routine, we recommend you cease using moisturising products to avoid compromising results. The potent combination of 100% active ingredients can hydrate, nourish and protect skin cells replacing day cream, night cream, eye cream and face masks.

Reviews

Game changer duo

"I alternate between this duo and the BM serum. Absolutely love Biologi serums. So nice that they soak into the skin rather than sit on top like so many other brands. I also feel like they do what they say."

Talisa (5/5)

Like no other

"This serum has helped my skin like nothing else, occasionally I get very bad eczema and when I don’t have Radiance around I can tell the difference."

Vale M. (5/5)

I think I finally found the one.

"My skin is not very problematic but I had 2 issues: dehydration and somewhat uneven texture due to clogged pores. I have a very healthy lifestyle/diet and drink plenty of water. In the last few years, I have tried different things from treatments at skin clinics (DMK, microneedling and skin clinic exclusive products) to brands from Sephora/Mecca but nothing seemed to fix my dehyration until I found Biologi 4 months ago. Normally before, my skin would look dehyrated/dry/dull after 1-2 hrs of applying products or the next day after those spa treatments. But with Biologi (radiance pack), hydration is long lasting and I did try not using any Biologi product one morning and my skin still looked quite supple despite being outside for hours on a windy day. I think it had fixed my dehydration My clogged pores- I think I still need more time to see. It has helped clear some clogged pores. It's no longer that sticky after 3 months - I will continue using Biologi as it's very beneficial for my skin. It's unlike any product that I used before. Just make sure you start slowly and follow the instructions as I rushed into it and I got very bag purging and nearly gave up on Biologi before"

Best serums on the market

"Amazing products for pigmentation....best products I have ever used and has transformed my skin . Love 🤍"

Annie (5/5)

Can’t live without these serums

"I love that these serums are made with local Australian ingredients: Kakadu Plum and Quandong. I’ve been an avid user of the Bqk serums and nothing really compares. Highly recommend!"

Maria M. (5/5)

Surprised

"Ok, I have been really surprised how good Bqk is. Why? Well, I've normally use Bf-restore, and have for a couple of years now. That has been very good and I was pleased with it. I have dermatitis, and it also helped to heal that and to keep it healed. I wasn't sure about trying anything else or, to be honest, if there would actually be a difference. But, I've been using Bqk for a few weeks now. My skin is definitely looking even better - there is an improvement, and also it hasn't activated my dermatitis. I was impressed by Bf but Bqk has been even better."

AMS (5/5)

Bkq radiance

"It’s awesome my face is clear and healthy"

Pamela B. (5/5)

Cheryl H. (5/5)

Love it wish I had bought it in a bigger size.

"Love the product, always leaves my skin with a beautiful glow and none oily or sticky"

Rylie M. (5/5)

Thumbs up 👍

"I do like this these two morning and evening serums. After using a cream for years, I'm still adapting to them being a serum. A little bit goes a long way."
