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

Phenolic Acids

The Science

Phenolic acids provide significant antioxidant protection against free radical and environmental damage. While rehydrating and plumping skin, phenolic acids also reduce inflammation and minimise redness.

Why do lips need phenolic acid?

    • Hydration
    • Anti-ageing potential
    • Significant antioxidant protection from free radicals and environmental damage
    • Enhance natural shine
    • Anti-inflammatory properties
    • Reduce redness
    • Reduce sun spots and blemishes


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

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!

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.

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!

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.

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.

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.

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.

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.

    OMG!!! Just AMAZING!!!! I have been using This lip serum for just 2 DAYS and already have noticed a massive difference with the texture and fullness of my lips. I have been suffering from dry cracked and peeling skin from my lips for a long time and no matter how much lip balm I have been putting on it just made my lips more dry and cracked. BL is a game changer, my lips feel soft and nourished and no more dry cracked lips, no peeling. I am just amazed at this product, it worked in 1 day! Will definitely be using only this serum on my lips! Bye-bye lip balm!

    Game changer! I applied this product for the first time last night and I’m very impressed. You only need apply the tiniest amount the results are evident the very next day. Being water based, the serum is quite fluid, yet easy to apply with the applicator. I was pleasantly surprised by the sweet taste that imparts from this serum. My lips were aglow but not sticky. Looking in the mirror this morning I can see my lips definitely look healthier – they seem to have more colour. There is also a freshness and softness that I’ve never seen before and I’ve tried dozens of “nourishing” and “plumping” lip products over the years. Well done Biologi, well done! I look forward to your next product launch.

    Wow! Wow, wow, wow…
    My lips have always been really dry, thin and kind of colorless however, my lips have completely transformed since I started using the BL lip serum. They are now super hydrated, they are noticeably (to me) fuller and plumper and they have colour!! I honestly cannot believe these are the same lips! Everyone needs this serum – whether you are living through the heat of summer or the cold of winter. I love that there areabsolutely no nasties near my mouth and if you do happen to lick your lips, it tastes delicious! Thank you Biologi for yet another incredible product. I think this one is my fave!
