Neogenesis PDO Mono, Screw and Cog threads are not three strengths of the same product. They are three structures for three different starting goals: skin-quality support, localized support, or mechanical tissue repositioning. The useful choice begins with what the customer actually wants changed, then moves to the exact SKU the clinic is trained to use.
The short answer
Choose the structure before the size
Start with Mono when the customer asks about fine texture, crepey-looking skin or broad skin-quality support without a lifting promise. Start with Screw when the same smooth-thread conversation needs more localized tissue contact and support. Move to Cog when the goal itself includes anchoring and repositioning tissue—and only when that service is already part of the clinic’s trained menu.
Mono
Smooth single strand. Best first fit for a skin-quality and collagen-support objective, not meaningful mechanical repositioning.
Screw
Smooth spiral strand. Moves the conversation toward localized support or volume, but does not turn a smooth thread into a cog lift.
Cog
Barbed strand. The architecture designed to clasp tissue for mechanical anchoring and repositioning.
Start with the customer request
What situation points to which thread?
Fine, crepey-looking skin or broad texture support
Mono is the cleaner starting point when the customer wants a subtle skin-quality plan across an area and is not asking for tissue to be mechanically moved.
A more localized support or volume objective
Screw makes more sense when the clinic wants a spiral smooth thread with greater local tissue contact than a flat Mono, while keeping expectations separate from a barbed lift.
Mild laxity or a contour concern that needs anchoring
When the customer request includes visible repositioning rather than skin-quality support alone, a barbed architecture is the relevant family to assess.
A defined nose-thread service
Neogenesis Nose Cog belongs in a nose-specific service, not in a general Cog order by default. The service, training and exact model must already be clear before it enters inventory.
PDO Mono vs Screw vs Cog
The practical comparison at a glance
| Decision field | Mono | Screw | Cog |
|---|---|---|---|
| Physical structure | Smooth monofilament | Smooth monofilament arranged in a spiral | Barbed thread with a defined direction and geometry |
| Primary starting goal | Skin-quality and collagen-support conversation | More localized support or volume conversation | Mechanical anchoring and repositioning conversation |
| What it should not be sold as | A mechanical lift | A barbed Cog lift or filler replacement | A universally stronger choice for every customer |
| First Neogenesis product to review | PDO Mono Thread | PDO Screw Thread | Combi Cog, Cog 360, Molding Cog or Nose Cog |
| Next purchasing question | Which gauge, length and delivery format fit the service? | Where is localized support actually part of the menu? | Which barb direction, geometry and delivery system match the trained service? |
Why the structures behave differently
Smooth support and mechanical anchoring are different jobs
Mono and Screw stay in the smooth-thread family
A Mono thread is one smooth strand. A Screw thread is also smooth, but the strand follows a spiral form. That extra geometry changes local tissue contact and can move the discussion toward support or volume.
The important limit is simple: neither structure has the barbs that create tissue purchase. A Screw can sit between Mono and Cog in a clinic’s menu, but it is not a halfway-strength Cog.
Cog adds a mechanical feature
Cog threads have barbs that engage tissue. This is why they enter the conversation when the desired change includes anchoring and repositioning rather than skin-quality support alone.
The second decision begins here. Direction, barb arrangement, barb shape and delivery system all change the product object. A 4D Combi Cog, a 9D bi-directional Cog, a molded flat-arrowhead Cog and a Nose Cog should not be collapsed into one generic “lifting thread.”
Inside the Neogenesis Cog family
Four Cog configurations, four inventory roles
Combi Cog
Uses multidirectional barbs arranged around the thread. It is the broader first Cog family to review when the clinic needs a barbed option and the offered service matches the available gauge and delivery choices.
Cog 360 Bi-Directional
Uses a bi-directional barb arrangement around the thread. The meaningful question is not whether “9D beats 4D,” but whether this exact direction and delivery configuration match the clinic’s intended service.
Molding Cog Arrow-Bi
Uses molded, flat arrowhead-shaped bi-directional barbs. This is a distinct geometry and presentation, so it deserves its own purchasing decision rather than being treated as a premium label for every lifting request.
Nose Cog
Uses a nose-specific unidirectional fixing-barb design. It belongs in inventory only when the clinic already provides a defined nose-thread service with suitable training and product documentation.
Read the exact SKU
Five fields that matter more than the product-family name
1. Architecture
Confirm smooth Mono, smooth spiral, or barbed Cog first. If this field is wrong, the rest of the specification cannot rescue the purchasing decision.
2. Gauge
Gauge identifies the delivery needle or cannula diameter; it is not a universal “power” score. Read it together with the thread and delivery format.
3. Needle or cannula length
This describes the delivery component. Do not assume it is the same as thread length, and do not compare two SKUs from one length number alone.
4. Barb direction and geometry
For Cog products, confirm unidirectional, bidirectional or multidirectional architecture and the named barb form. This is a real product difference, not decorative wording.
5. Model code and pack quantity
Use the exact model code to confirm the selected combination. Pack quantity then affects stock planning, but it does not tell you which architecture fits the service.
Before placing an order
Ask Cytollia to confirm the exact variant, current presentation and applicable product documentation instead of ordering from a family name or screenshot.
Clinic stocking logic
Build the range around services you actually provide
Skin-quality-led menu
Start with Mono. Add Screw only if localized smooth-thread support is a real, repeatable service—not simply because another SKU exists.
Mixed rejuvenation menu
Mono plus Screw can cover two distinct smooth-thread conversations. Add a Cog family only when anchoring and repositioning are part of the trained service range.
Lift-focused menu
Select the Cog geometries that correspond to actual procedures, delivery preferences and documentation. Carrying every 4D, 9D and molded option is not automatically a better assortment.
Nose-specific menu
Add Nose Cog only for an established nose-thread service. A specialized SKU without matching demand and training creates complexity, not useful breadth.
Avoid the common buying errors
Five shortcuts that produce the wrong order
Treating every PDO thread as interchangeable. Material alone does not tell you whether the structure is smooth, spiral or barbed.
Promising a Cog-style lift from Mono. Mono supports a different customer goal and should be described that way from the start.
Using Screw as a vague compromise. Screw has a real localized-support role, but it is not “a little bit of Cog.”
Choosing by gauge or D-count alone. A number cannot replace the architecture, model, delivery system and service match.
Ordering Nose Cog as a general range extender. Specialized inventory should follow an established service, not create one by accident.
A better procurement request
What to send Cytollia before asking for a quotation
Skin quality, localized smooth-thread support, general Cog lifting, or a nose-specific service.
Mono, Screw, or the exact Cog configuration. Do not write only “Neogenesis PDO threads.”
Request the model code, gauge, delivery length, thread length, barb direction, pack quantity and current documentation.
Frequently asked questions
Neogenesis PDO thread FAQ
Is a PDO Mono thread the same as a thread lift?
No. Mono is a smooth, non-barbed architecture used for a skin-quality and collagen-support objective. It does not provide the mechanical tissue anchoring associated with a barbed Cog thread.
What is the practical difference between a Mono and a Screw PDO thread?
Both are smooth threads, but Screw is arranged in a spiral. That construction moves the choice toward localized support or volume rather than the flatter skin-quality role of Mono. Screw is still not a barbed Cog lift.
What makes a Cog PDO thread different?
A Cog thread has barbs that engage tissue. This is the architecture used when the objective includes mechanical anchoring and repositioning, rather than skin-quality support alone.
Does 9D automatically mean better than 4D?
No. The labels describe different barb arrangements. They do not prove that one product is universally better for every tissue, area, service or customer goal.
Can a Nose Cog be used as a general lifting Cog?
It should be treated as a specialized nose-service SKU, not as a default substitute for the broader Cog range. A clinic should stock it only when the matching service and training already exist.
What should a clinic check before ordering a Neogenesis thread SKU?
Confirm the architecture, material, gauge, needle or cannula type and length, thread length, barb direction or geometry, model code, pack quantity, current documentation and the exact service the clinic plans to offer.

Bottom line
Match the customer’s goal, then match the SKU
Mono is the skin-quality starting point. Screw adds a localized smooth-thread support option. Cog is the barbed family for anchoring and repositioning. Within Cog, 4D, 9D, molded arrowhead and nose-specific designs are separate inventory decisions—not a simple ladder from weaker to stronger.
A good Neogenesis order therefore begins with the clinic’s real service menu and ends with an exact model code, specification and pack. It does not begin with the biggest number on the page.
