What is supports
The Biology Serum’s design intrinsically supports a variety of skin concerns - including:
- Skin prone to dehydration or dullness
- Skin prone to sensitivity or redness
- Skin showing premature signs of aging
- Skin showing loss of firmness, worse texture, or uneven tone
- Skin exposed to environmental or product-related stressors
- Skin prone to outbreaks
- Skin that’s already healthy
How it works
1. Supplement
The Biology Serum delivers immediate hydration and 397 naturally-occurring proteins. They are documented to have anti-inflammatory, anti-aging, and anti-oxidative properties. To ensure the active proteins remain potent and your skin undisrupted, the formulation is 24% gentler than water and contains no wide spectrum preservatives.
We designed The Biology Serum to be entirely compatible with skin. Sitting at pH 5.2 (the optimal pH for female skin) and made for the skin topography. By using the smaller molecular salt form of HA, we deliver actives deeper than any other skincare product.
2. Support
Unlike skincare, we don’t try to force a specific result, we let your skin use what we supply it with when and where it needs it. By providing a comprehensive support package for the very systems that underpin skin function - we let it do all the work.
Hydrated cells, healthy microbiome, strong barrier, and supported natural moisturising factor production are all supported by the formulation’s six ingredients. These are very the systems that evolved to respond to stressors and demands through connective signalling pathways.
How it's made
Making The Biology Serum begins with the best ingredients - that’s why we only work with pharmaceutical-grade suppliers.
Our all-women team of scientists handle each stage of the production process with precision - using the best available equipment and packaging. The cryovials that hold The Biology Serum are sourced from Greiner. They’re usually reserved for cutting-edge research and capable of withstanding temperature of -196c.
In an controlled GMP grade A environment, we prepare the serum in small batches and hand-fill each vial. This ensures there is no risk of contamination and it’s what enables us to forgo preservatives. The product then remains refrigerated while it’s transported to you.
How to use
Step 1. Keep only one vial open at a time - once opened a vial lasts 10 days.
Step 2. Measure out around 0.5ml - use the vial’s markings.
Step 3. Apply the serum to the desired area - just as you would any other product.
Step 4. Use twice a day for best effect - AM and PM.
Step 5. Return to your fridge.
Experience the next step in skin evolution
Our skin evolved for a world that no longer exists.
Despite widespread skincare use - 70% of people today have sensitive skin.
Building on our work pioneering autologous stem cell therapy, The Biology Serum™ is designed to close the gap between skin evolution and modern life.
For visibly healthier skin. Not a temporary fix.
How we did it
Made by scientists. Designed by evolution.

Testimonials
Since using it my face has really settled down. It used to be quite red and patchy. I feel the product is really good at toning my skin down, evening it out, and also providing me with quite a bit of moisture.
Since using The Biology Serum™ I have noticed a considerable reduction in dryness and my skin feels a lot smoother and more supple! Quite remarkable as I would normally re-apply my moisturiser 2-3 times a day, but I haven't applied any other moisturiser and my skin feels totally moisturised.

Frequently asked questions
Can I use other skincare products?
The Biology Serum™ is designed to replace a full skincare routine - and the longer you use it, the less your skin will need anything else.
For those who want to use it as part of a routine, it works beautifully as a hydrating, protective layer beneath makeup or any other products you enjoy - just know that your results might take longer, or feel less complete.
How long will it last me?
An order of 9 vials can last anywhere between 1 to 2 months, but this varies by use!
Each vial, once opened, must be discarded if not used within 10 days.
How much do I apply?
For optimal results, we recommend applying .5mL twice a day - but you can use and apply however much feels right. The side of the vial has graduations with mL markers, so you can see how much you're using.
It can take a few applications to get the hang of it, and find the amount that's right for your skin.
Can I travel with it?
You can travel with unopened vials.
How to apply?
To apply, either:
Unscrew vial cap and pour serum out into your hand to achieve the amount that feels right to you. Apply to your face. It may take some getting used to until you get the right amount each time.
OR
Unscrew the vial cap, press your index finger pad down over opening, and briefly invert vial upside down. There will be serum on your finger pad. Apply to your face, then repeat until satisfied with coverage
Ensure vial is returned to fridge after use.

Where do I keep my vials?
Because we make The Biology Serum™ fresh without preservatives, your vials need to be kept fresh in the fridge. Actevna® vial holders are designed to fit in a fridge door shelf.
