Pixcell Biom™ 2Billion/ml (30ml)

Use morning and/or evening immediately after cleansing.

Apply a few drops across the face and gently pat into the skin until absorbed.

Follow with toner if you use one, then continue with serum, moisturiser and SPF in the morning.

Because the texture is so light, you can also layer it underneath richer barrier serums or creams without making the routine feel heavy.

Tips to get the most out of it

• Use it as your first leave-on step after cleansing rather than treating it like a final serum

• If you're introducing retinal, retinol or exfoliating acids, this can form part of the simple supportive side of your routine

• Don't expect it to compensate for over-exfoliation. If your skin is becoming progressively redder, tighter or more sensitive, reduce the irritating products as well

• If your routine already contains several essences and hydrating serums, you don't necessarily need all of them alongside this — keep the layers that are actually helping your skin

• Oily and acne-prone skin can still have a compromised barrier. Barrier support does not need to mean using a thick cream at every step

• If your skin is extremely reactive, introduce any new product one at a time so you can tell what your skin actually tolerates

• You can mix a few drops into moisturiser, but applying it directly after cleansing makes the most sense if you want to use it as PURCELL's intended first-step treatment

Bifida Ferment Lysate (45%), Lactobacillus Ferment Lysate (45%), Butylene Glycol, 1,2-Hexanediol, Ethylhexylglycerin

Good to know

• Ferment lysates are broken-down probiotic bacteria, not live cultures
• No fragrance in the ingredient list

What exactly is PURCELL Pixcell Biom™ 2Billion/mL?

It is an extremely concentrated ferment-lysate treatment built around two ingredients: Bifida Ferment Lysate and Lactobacillus Ferment Lysate.

Each makes up 45% of the formula, giving a combined concentration of 90%.

The remaining formula is very simple, making this quite different from a typical serum containing dozens of botanical extracts and actives.

-
Does it contain live probiotics?

No — the ingredient list contains Bifida Ferment Lysate and Lactobacillus Ferment Lysate rather than live probiotic cultures.

“Probiotic skincare” is commonly used as an umbrella marketing term, but in this case the ingredients are bacterial lysates.

You don't need live bacteria on your skin for this product to be useful as a barrier-supporting treatment.

-
What does “2Billion/mL” actually mean?

The name refers to PURCELL's concentration specification for its Pixcell Biom™ ferment material.

What it does not mean is that you are applying two billion living probiotic bacteria to every millilitre of skin.

For everyday skincare purposes, the more useful information is that 90% of the finished formula consists of Bifida and Lactobacillus ferment lysates.

-
Should I use it before or after toner?

Before.

PURCELL positions this as a first-step treatment, so use it directly after cleansing and follow with your toner, serum and moisturiser.

If you've already applied toner occasionally, however, you haven't ruined the product. Skincare does not need to become that rigid.

-
Is it good for a damaged skin barrier?

This is one of the main situations in which we would consider it.

The formula is deliberately focused on barrier support and is lightweight enough to sit underneath your moisturiser.

But if your barrier is genuinely compromised, adding this while continuing to over-exfoliate or use irritating actives every night is unlikely to solve the problem.

Think barrier-supportive routine, not just barrier-supportive serum.

-
Can I use it with retinol or retinal?

Yes, there is no obvious reason you need to separate these ferment lysates from retinoids.

In fact, a simple barrier-supporting product can make sense within a retinoid routine.

What it won't do is make an overly aggressive retinoid schedule suddenly tolerable. If you are burning, peeling significantly or becoming increasingly sensitive, reduce the retinoid frequency rather than simply adding more recovery products.

-
Can I use it with AHA or BHA?

Yes, but again, look at the whole routine.

There is no inherent need to keep Pixcell Biom™ away from exfoliating acids. It can sit within the hydrating/barrier-supporting portion of that routine.

If your skin is already irritated from acids, however, give it recovery time rather than continuing to exfoliate through the irritation.

-
Is it suitable for acne-prone skin?

Yes, particularly when acne-prone skin has become dehydrated or sensitised from cleansing, exfoliants or acne treatments.

It is not an acne treatment and shouldn't be expected to clear blocked pores or active breakouts by itself.

Its role is different: supporting the condition of the skin and its barrier while the appropriate acne treatment does the targeted work.

-
Will it feel heavy on oily skin?

Very unlikely.

The texture is extremely watery and lightweight, which makes this one of the easier forms of barrier-focused skincare to incorporate into oily or combination routines.

-
Does it replace moisturiser?

No.

This is a lightweight treatment layer, not an occlusive moisturiser.

If your barrier is compromised or your skin is dry, follow it with an appropriate moisturiser to help reduce water loss and provide the lipids and emollients your skin may also need.

-
How often should I use it?

It can be used morning and evening if your skin enjoys it.

Unlike retinal or exfoliating acids, you don't need a complicated schedule simply because the formula contains “90%” of its key ingredients.

That percentage describes the concentration of ferment lysates rather than the strength of an exfoliating or irritating active.
