HERO INGREDIENT: Australian Native Blood Red Finger Lime

  • Our serums contain 99.8% Citrus Australasica (Australian Native Blood Red Finger Lime) 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.

Frequently Asked Questions

Is BL Safe To Use Around My Mouth?

Yes! Biologi BL Nourish Lip Serum is free from harmful chemicals, and fragrance. The BL extract is plant extract of blood red finger lime and contains sodium benzoate preservative at 0.2%

Is BL Coloured Or Tinted?

No. We don't add artificial colours to our lip serum, so the colour appears exactly as it does in the fruit. While BL will give your lips a clear shine, if it's colour you require, we recommend you choose a lipstick or lip gloss.

Does It Taste Like Chemicals?

No. BL has a naturally sweet taste due to the sugar content that makes the extract ideal as a lip serum. The serum is free from all synthetic ingredients so it’s safe to ingest, we don’t add anything to make it taste nice because we don’t need to!

How Do I Apply The Lip Serum?

Simply, twist the bottom of the applicator to release the serum onto the lip applicator tip and apply to dry lips.  Use before lip colour.  BL Serum may be used throughout the day or as an overnight lip conditioning treatment. To avoid cross contamination, do not use the applicator over any lip skin infections.

Can I Use BL Nourish Lip Serum With My Regular Lip Balm?

We don't recommend you use any other lip conditioners or balms with the BL Nourish. Traditional lip balms can often contain occlusive ingredients which can trap toxins and block pores. As BL is a water-based solution, this congestion will stop the active ingredients penetrating the deeper layers of the lips, so the product won't work as well.

Is The Blood Red Finger Lime In The BL Lip Serum The Same As The Bf Restore Face & Body Serum?

No! The Bf Restore Face & Body serum contains Finger Lime, the BL Lip serum is an extract of Blood Red Finger Lime. The phyto actives in BL specifically target dry lips and assist with cooling and soothing while reducing transepidermal water loss to keep lips hydrated.

What Does The Lip Serum Feel Like?

BL is not a lip balm or lip gloss and doesn’t leave a heavy residue on the lips. The serum is water-soluble, so it soaks in leaving lips feeling soft, smooth and supple.

Is It Safe To Apply BL On Irritated, Burnt Or Chapped Lips?

The BL Lip Serum can be used over common lip complaints like chapped, sun exposed and dry lips to help soothe, hydrate and protect. We do not recommend using over broken skin, skin infections or reactions.

Is It Normal To Notice Cloudy Parts In My Serum?

Yes, It's nothing to be worried about at all, and is common in our extracts. This is the pectin from the fruit extract, and the amount varies from batch to batch, it does not affect the potency or quality but proves how natural these serums are. Simply give it a good shake and this will disperse.
