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.


MORNING (lighter in colour)

  • After cleansing, apply Bk (lighter in colour) morning Serum to a clean dry skin.

  • After cleansing apply the Bqk (darker in colour) evening serum to a clean dry skin.

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.


Use for

Bqk serum contains Vitamin C and pigment inhibiting phyto-actives that work together to help reduce the appearance of pigmentation and redness in the skin as well as preventing further uneven skin tone. Bqk serum duo is a active, simplified morning and evening regime that aims to improve skin imperfections and clarity.

This set comes with both a morning and evening serum. The Bk Vitamin C Face & Eye Serum and the Bqk AM Serum are made of the same extract.

Plant extract

Kakadu Plum

Sourced from indigenous communities in the Northern Territory, the Kakadu Plum plant is known to contain high levels of Vitamin C. Kakadu Plum extract helps to promote collagen production in the skin to increase suppleness and diminish signs of ageing.

It also works well on skins with pigmentation and redness/discolouration.

Phyto-actives include: Vitamin C, Gallic Acid and Ellagic acid.


Plant extract


Sourced from Broken Hill in New South Wales, Quandong extract contains a storehouse of antioxidants. This native Australian treasure is effective on skin with pigmentation, redness, uneven tone and lacking hydration to leave the skin glowing and radiant. Quandong also helps prevent melanogenesis – the formation of pigmentation from occurring.

Phyto-actives include: Tryptophan, Ferulic acid, Rutin and Chlorogenic Acid.

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.
