The Ultimate Guide to Neocutis (2026): PSP Growth Factors, Bio Serum Firm and the Top 8 Products

Here is the contrarian part: Neocutis is not trying to be exciting, and that is exactly why it works. No app, no twelve-step system, no launch every quarter: a short line of products built around one idea, and the idea predates the growth factor trend it quietly started.

That idea is PSP, which stands for Processed Skin Cell Proteins. It came out of Swiss wound-care research, and Neocutis took the proteins skin uses to repair itself and put them into a serum and a cream for people who simply wanted to look less tired. The brand now sits inside the Merz Aesthetics family, the same house that makes injectables you have heard of, which tells you something about how clinics regard it.

This is the honest version of the Neocutis story: what PSP actually is, what the Firm line adds on top of it, which of the ten products on our shelves earn their price, and the three routines our clinical team builds with them. WeDoSkin is an authorized Canadian retailer for Neocutis, and every price below is live.

Where Neocutis Came From, and Why It Matters

A skincare brand born in a wound-care lab

Most skincare brands start with a founder and a feeling. Neocutis started in Switzerland with researchers looking at how young skin repairs itself with almost no scarring, and asking whether the proteins behind that could be cultured and used elsewhere. The answer became PSP, and the first products were made for skin recovering from procedures, not for a beauty counter.

That origin is still visible in the line. The textures are plain, the fragrance is absent or minimal, the packaging is clinical, and the instructions are short. It is a brand designed to be handed to a patient by a nurse, and it still behaves that way.

Now part of Merz Aesthetics

Neocutis today belongs to Merz Aesthetics, the company behind some of the most widely used injectable treatments in clinics. That matters for two reasons. It means the brand has the manufacturing and quality control of a pharmaceutical group behind it, and it means the products are designed to sit alongside procedures rather than compete with them.

PSP, Explained Without the Marketing

What Processed Skin Cell Proteins actually are

PSP is Neocutis' name for a blend of growth factors, cytokines and other signalling proteins harvested from cultured skin cells. Think of growth factors as the memos skin cells send each other: make more collagen, calm down, repair this, build that. As skin ages it sends fewer memos and reads them less carefully. A topical growth factor product is an attempt to add more memos to the pile.

Where Neocutis differs from a lot of the category is in the source and the balance. PSP is a complete mix of the proteins skin cells naturally produce, rather than a single growth factor isolated and added at a headline percentage. Skin, in our experience, responds better to the full conversation than to one voice shouting.

What growth factors can and cannot do

The honest limits first. Growth factors are large molecules and they work at the surface and upper layers of skin, where they support the cells that build collagen and elastin over time. They do not fill a wrinkle the way an injectable does, and they do not resurface skin the way a retinol or an acid does. What they do, used daily for eight to twelve weeks, is improve the quality of the skin you have: firmer, smoother, more even, more resilient.

That is why Neocutis works so well alongside procedures and alongside retinol. The retinol or the laser does the renovation; the growth factors support the rebuild. If you want to understand how the category compares with exosomes, PDRN and peptides, our regenerative serum showdown runs the full comparison.

The MPC peptide complex: the Firm in Firm

Every product with Firm in the name adds a second engine to PSP: the brand's proprietary micro protein complex of peptides. Peptides are shorter chains of amino acids that act as building blocks and signals for the proteins that keep skin taut. Pairing them with growth factors is the reason the Firm products are positioned for loss of firmness specifically, rather than for general recovery. For a wider look at the ingredient class, read our peptide serum guide.

The Line, Decoded: Which Neocutis Is Which

The Firm family: serum, cream, gel, eye and neck

Five products share the Firm name and the same core chemistry. Bio Serum Firm is the concentrate. Bio Cream Firm and Bio Cream Firm Riche are the moisturizer in normal and extra-nourishing weights. Bio Gel Firm is the oil-free hydrogel. Lumière Firm and Lumière Firm Riche are the eye creams, and Neo Firm is the neck and décolleté cream. You choose by texture and by zone, not by potency ranking; the serum is simply the one that carries the most active per application.

The supporting cast: Hyalis+, Perle and Neo Cleanse

Hyalis+ is the hydrating serum, built on a multi-molecular hyaluronic acid complex rather than growth factors. Perle is the brightening cream, hydroquinone-free and designed for stubborn dark spots and uneven tone. Neo Cleanse Gentle is the cleanser. None of the three is glamorous; all three get repurchased quietly for years.

Who Neocutis is for, and who should look elsewhere

Neocutis is for people over thirty who want firmer, better-quality skin without irritation, for anyone recovering from a procedure, and for the many people with reactive skin who have been told medical-grade skincare is not for them. It is not the brand for someone chasing a strong exfoliating or resurfacing result. There is no retinol in the line and the only acid is the measured glycolic in Neo Firm. If you want renovation, pair it with a retinol from another house; if you want a quiet, well-built rebuild, you are in the right place.

The #1 Pick: Bio Serum Firm

The Neocutis 8: Every Product Worth Buying in Canada

Eight of the ten products on the store, ranked by how often our clinical team sends each one home. Nobody needs all eight. Most people need the serum, one moisturizer and the eye cream.

1 · The Flagship

Bio Serum Firm

The most concentrated expression of what Neocutis does: PSP growth factor proteins plus the brand's proprietary peptide complex in a lightweight serum that disappears into skin in seconds. If you buy one Neocutis product for lines, firmness and dullness, this is it, and it layers under almost anything. Compare it to the wider field in our growth factor serum ranking.

2 · The Daily Moisturizer

Bio Cream Firm

The same growth factor and peptide story delivered as a rich, smoothing cream. It is the moisturizer we reach for when someone wants a single step that hydrates and works on firmness at the same time. Dry or mature skin in a Canadian winter should look at the richer Bio Cream Firm Riche instead.

$165.00Shop →

3 · Oil-Free, Post-Procedure

Bio Gel Firm

Oil-free, cooling and weightless, which is why it shows up in our oily skin over 40 guide. It carries the growth factors and peptides without any richness, so it suits combination skin, men who refuse cream, and the fragile week after a laser or peel.

$180.00Shop →

4 · Eyes

Lumière Firm Eye Cream

Growth factors, peptides, caffeine and bisabolol in a silky texture that sits well under concealer. It addresses puffiness, dark circles and fine lines at once rather than picking one, which is why it converts so many first-time buyers. Dry or crepey under-eyes should step up to Lumière Firm Riche.

$100.00Shop →

5 · Neck and Décolleté

Neo Firm

A dedicated neck cream that combines peptides, sodium carboxymethyl betaglucan and a measured dose of glycolic acid, so it works on crepiness and uneven tone at the same time. It holds its own in our neck cream ranking.

$160.00Shop →

6 · Hydration

Hyalis+ Serum

A multi-molecular hyaluronic acid serum that does one job and does it without drama. It is the partner product for Bio Serum Firm on dehydrated skin, and the one to buy on its own if your only complaint is tightness and fine dehydration lines.

$121.00Shop →

7 · Brightening

Perle Cream

A hydroquinone-free brightening cream built around Melaplex technology, cushioned with shea butter, jojoba oil and vitamins C and E. It is the gentlest route Neocutis offers for stubborn dark spots and uneven tone, and it doubles as a light moisturizer on normal skin.

$127.00Shop →

8 · The Cleanser

Neo Cleanse Gentle

Sulfate-free, fragrance-free, glycerin-based and $36, which makes it the least expensive way into the brand and the one we recommend for the two weeks after any procedure. It removes makeup without leaving skin squeaky, and squeaky is the enemy of every serum on this page.

$36.00Shop →

The two products not in the grid, Bio Cream Firm Riche ($180) and Lumière Firm Riche ($110), are the richer twins of Bio Cream Firm and Lumière Firm. Choose them when your skin is dry, mature or facing a Canadian January. Everything is in the Neocutis collection.

Bio Serum Firm vs Bio Cream Firm vs Bio Gel Firm

The three products people cross-shop most, side by side. Same chemistry, three different textures, three different people.

The verdict: Bio Serum Firm if you can only buy one, because it delivers the most active per application and works with whatever moisturizer you already own. Bio Cream Firm if you want a single-step routine on normal to dry skin. Bio Gel Firm if your skin is oily, reactive or recovering. The serum plus one of the two moisturizers is the complete answer; buying both moisturizers is the mistake.

Three Routines Our Clinical Team Actually Builds

Neocutis is simple to layer: cleanse, serum, moisturizer, SPF in the morning. Pick the routine that matches your skin and run it for twelve weeks before judging.

Five Mistakes That Make Neocutis Look Like It Does Nothing

1. Expecting it to behave like retinol

Growth factors do not peel, tingle or purge. People used to retinol read the absence of drama as the absence of results and quit at week three. Neocutis works in the background, and the proof is the photo at week twelve, not the sensation at night one.

2. Applying the serum over a moisturizer

Bio Serum Firm goes on clean, dry skin before anything else. Put it over a cream and most of it sits on top of an oil layer doing very little. Cleanse, serum, wait a minute, then moisturizer. The order is the whole technique.

3. Buying both moisturizers

Bio Cream Firm and Bio Gel Firm are two textures of the same idea for two different skins. Owning both means one of them expires in a drawer. Pick by how your skin feels at 3 pm: shiny means gel, tight means cream.

4. Skipping sunscreen on the brightening routine

Perle works on existing pigment; daylight makes new pigment faster than any cream can clear it. A mineral SPF every morning is not optional on this routine, it is the other half of the product. Our tinted mineral sunscreen guide has the ones that look good on skin.

5. Using a stripping cleanser first

A foaming, squeaky cleanser leaves skin slightly compromised, and growth factors applied to compromised skin are wasted on repair work you caused in the shower. Neo Cleanse Gentle costs $36 and protects a $270 serum. That is the best value ratio in the line.

Neocutis vs SkinMedica vs AnteAGE: Picking a Growth Factor Brand

The three growth factor houses Canadian clinics stock most are Neocutis, SkinMedica and AnteAGE, and they are not interchangeable. SkinMedica's TNS line is the most studied and the most expensive, built on a human fibroblast-derived growth factor blend; our SkinMedica guide covers it in depth. AnteAGE uses bone-marrow-derived stem cell signals and leans into exosome technology. Neocutis uses PSP from cultured skin cell proteins and adds a peptide complex, and it is the most affordable of the three at the serum level.

Our honest steer: SkinMedica if budget is no object and you want the longest paper trail; AnteAGE if you are chasing the newest regenerative science; Neocutis if you want a complete, well-priced system that sits comfortably beside procedures and never irritates.
