BL Nourish Lip Serum is a single-plant extract of native Australian blood red finger lime.

Chosen for its natural repairing and protection properties, the blood red finger lime is packed with 100% active natural phytonutrients that work in synergy to reduce redness, calm the skin on the lips and leave lips softer and more supple than ever before.


Why choose BL lip serum?

BL lip serum is a revolutionary serum unlike other glosses and balms on the market. Rather than sit on top of the lips causing congestion, the unique water-soluble formulation penetrates the skin’s deeper layers to regenerate cells, increase suppleness and aid hydration while providing a clear shine.

Ingredients: Citrus Australasica (blood red finger lime), 0.2% Sodium Benzoate

Use BL Nourish Lip Serum for:
  • Deep overnight conditioning treatment
  • Hydration burst throughout the day
  • Antioxidant protection
  • Clear shine
  • Smoothing and softening
  • Gently regenerate and exfoliate the surface of lips
  • Deeply repair damaged cells caused by inflammatory lip conditions
Citrus Australasica (blood red finger lime) 100% active nutrients*


The science

Amines provide a storehouse of antioxidants which protect the skin against free radical and environmental damage. While working to reduce blemishes, the potent active also builds protein hydrolysate moisture into the cells to smooth and hydrate dry and chapped lips.

Why do lips need Amines?
  • Hydration
  • May reduce sun spots and blemishes
  • Significant antioxidant protection from free radicals and environmental damage
  • Smooth and moisturise dry lips

Deoxy Glucitol (sugar alcohol)

The Science

Naturally forming deoxy glucitol creates a cooling sensation on the skin helping to heal and soothe irritation. Working to prevent moisture loss and aid hydration, sugar alcohols are safe to ingest and help relive redness and irritation caused by inflammatory lip conditions or overexposure to sun and wind.

Why do lips need deoxy glucitol?
  • Hydration
  • Cool and soothe irritated skin
  • Healing anti-inflammatory properties
  • Significant antioxidant protection from free radicals and environmental damage

Flavone Glycosides

The Science

Flavone Glycosides are a group of phytonutrients that provide high concentrations of antioxidants to protect the skin and defend against free radical damage. Harnessing powerful anti-inflammatory potential, flavone glycosides also reduce redness and irritation while reversing the visible signs of ageing.

Why do lips need flavone glycosides?
  • Hydration
  • Significant antioxidant protection from free radicals and environmental damage
  • Anti-inflammatory and reduce redness
  • Reduce sun spots and blemishes
  • Anti-ageing potential

Frequently Asked Questions

Is BL safe to use around my mouth?

Yes! Biologi BL Nourish Lip Serum is the first lip treatment on the market that’s free from harmful chemicals, fragrance and even water. The BL extract is single-plant extract of blood red finger lime and contains sodium benzoate preservative at 0.2% – nothing else!

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?

Make sure lips are completely dry as contact with water can reduce the efficacy of the active ingredients. Twist the bottom of the applicator and the serum will move up into the brush, apply to clean dry lips before bed or throughout the day as required.

Can I use BL Nourish Lip Serum with my regular lip balm?

We don’t recommend you use any other treatments 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. BL is 100% active meaning lips are treated on a cellular level, so no other lip treatment is required.

Is the blood red finger lime in the BL lip serum the same as the Bf hydration serum?

No! The Bf hydration serum contains finger lime, the BL Lip serum is extract of blood red finger lime. The phytoactives in BL specifically target dry lips and assist with cooling and soothing while reducing trans epidermal water loss to keep lips hydrated.

What does the lip serum feel like?

Unlike any other product on the market, 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?

Absolutely! BL contains healing phytoactives that will help speed up the healing process of common lip complaints such as chapped lips, sunburn and cold sores.
