CEO & Founder bei Labtree GmbH
Sponge spicules promise something rare in skincare: an immediately noticeable, mechanism-led effect built into the product itself. The category is still early, which makes it a clear first-mover opportunity for brands that can formulate it responsibly.

Sponge spicules create temporary micro-channels in the skin and can support active uptake, giving a device-free, microneedling-style effect.
Effect and tolerability are formulation-dependent: spicule grade, concentration, supporting actives and format decide the outcome.
A pre-qualified base and early samples on real skin let a brand balance a noticeable effect against tolerability responsibly.
Sponge spicules are tiny, rigid, needle-like structures that occur naturally in marine sponges. In a finished cosmetic they are suspended in the formulation and, on application, create very fine, temporary micro-channels in the uppermost skin. This mechanical action is intended to support the penetration of accompanying actives and to encourage skin renewal, which is why the effect is often compared to at-home microneedling.
Interest is rising for two connected reasons. First, consumers increasingly want skincare with a noticeable, experiential effect rather than only a long-term promise, a shift we cover in our article on noticeable, experiential skincare. Second, spicules represent a wider move from ingredient-led to mechanism-led formulation, where the physical action of the product, not only an active, drives the result. That makes spicules a clear example of formulation that works through a mechanism rather than a single ingredient.

The market signal, framed as opportunity not guarantee
The demand around spicules is best read as a set of signals that point to a first-mover window, not as a promise of commercial success:
First-mover window: the category is still thinly populated compared with established actives, so a credible product can differentiate before the space fills.
Experiential pull: demand is rising for skincare with a felt, immediate effect, which suits a mechanism that consumers can perceive on first use.
Device-free positioning: a microneedling-style effect without a device addresses an audience that wants performance without clinic visits or at-home tools.
The practical reading: the opportunity is genuine and early, but it rewards a product that is formulated and dosed responsibly, because a mechanically active ingredient carries tolerability considerations that a passive active does not.
The formulation reality: size, dose, support and format
A spicule product succeeds or fails on formulation decisions. The mechanism is real, which is exactly why dosing and support matter. Effect and tolerability are formulation-dependent.
Spicule size and grade: the dimensions and consistency of the spicules influence both the intended effect and how the product feels, so the grade has to match the concept.
Concentration: more is not automatically better. The usable range balances a noticeable effect against tolerability, and depends on the rest of the formulation.
Supporting actives: because spicules can support the uptake of accompanying actives, the choice and concentration of those actives shape the overall result and have to be considered together.
Format and use guidance: spicules are typically used in a booster or treatment format with defined frequency, which protects tolerability and sets consumer expectations.
Because the mechanism is physical, claims should stay close to what the formulation supports and within cosmetic territory. This is performance skincare, not a medical treatment, and the messaging has to reflect that.
Positioning a spicule product so it differentiates responsibly
The positioning challenge is to communicate a noticeable effect without over-promising. Three angles tend to hold up:
Booster or treatment step: positioning the product as a periodic booster within a routine fits the mechanism and supports cross-selling alongside daily care. This connects naturally to boosting systems that make other products more effective.
Device-free performance: a clear, honest account of the at-home, device-free effect addresses the audience drawn to microneedling without the tool.
Measured, expert tone: because the ingredient is mechanically active, a calm and informed tone with clear use guidance builds more trust than dramatised messaging, and fits regulatory limits on claims.
Whatever the angle, the product should come with clear usage frequency and expectations. A noticeable effect is an asset only when it is framed responsibly.
How Labtree turns a spicule concept into a launch-ready product
The difficulty with a mechanically active ingredient is balancing a noticeable effect against tolerability, and doing so on a real product rather than on a specification. Developing that balance from a blank page is slow and uncertain.
At Labtree, development starts from a real formulation base rather than from scratch. Pre-qualified formulation bases give a brand early clarity on which spicule concept is actually producible, at what concentration, with which supporting actives, and in which format. That is the first differentiator in practice: development on a real formulation base instead of development into the unknown. Physical samples of pre-qualified formulations ship within 24 hours from the sample warehouse, free of charge for standard samples, so the felt effect, texture and tolerability can be assessed on real skin rather than in theory. Because development happens in our own lab, the spicule grade, dose and supporting actives can be specifically developed, tested and adapted, and smaller test batches can be produced in-house to validate the product early under real conditions.
The 5-phase process applied to a spicule booster
Conception: defining the format (booster or treatment), the target effect, the supporting actives and the price point, and matching them to a suitable formulation base from the Labtree pool.
Sampling: standard samples of pre-qualified formulations within 24 hours for a first read on the felt effect, texture and tolerability on real skin.
Individualisation: adjusting spicule grade and concentration, supporting actives and sensory profile, iterating with further samples until effect and tolerability are balanced.
Prototyping: a production-near test batch. Packaging, design, regulatory requirements and production capability are considered early and in parallel with formulation development, rather than addressed only after final formulation approval.
Production: scaling to the initial batch and into routine production, coordinated because production capability was considered during prototyping.
Own formulation base for spicules: are there pre-qualified spicule bases to start from, or does each project begin from scratch?
Own laboratory: can spicule grade, dose and supporting actives be adjusted and tested in-house, where tolerability is decided?
Tolerability focus: a partner who can iterate on the balance between effect and tolerability, not only on a stronger effect.
Sampling speed: samples within 24 hours is a realistic benchmark, and free standard shipping is a meaningful signal, because a felt effect has to be assessed on real skin.
Claim support: a partner who keeps claims within cosmetic territory and close to formulation performance protects the brand on a mechanically active ingredient.
Sponge spicules offer something the market increasingly rewards: a noticeable, mechanism-led effect built into the product, without a device. The category is still early, which makes it a genuine first-mover opportunity, but the ingredient is mechanically active and has to be formulated and dosed responsibly. With a pre-qualified formulation base, early physical samples that let the felt effect be assessed on real skin, and parallel handling of packaging and regulatory work, a credible spicule product becomes a structured, plannable project rather than a leap into the unknown.

FAQ
Does Labtree have its own laboratory?
Yes. Labtree has its own development competence including a laboratory. This means formulations are not only selected but specifically developed, tested and adapted. In addition, smaller test batches can be produced in-house to validate products early under real conditions and move them safely into production.
What are sponge spicules in skincare?
Sponge spicules are microscopic, needle-like structures derived from marine sponges. Suspended in a formulation, they create temporary micro-channels in the upper skin and can support the uptake of accompanying actives, producing a noticeable, device-free effect often compared to at-home microneedling.
Are sponge spicules the same as microneedling?
Not exactly. They produce a comparable mechanism, fine temporary channels in the upper skin, but built into a product rather than created by a device. This is performance skincare positioned within cosmetic territory, not a medical procedure, and claims should reflect that.
Is a higher spicule concentration better?
No. A higher concentration is not automatically better. The usable range balances a noticeable effect against tolerability and depends on the rest of the formulation. The right dose should match the concept and the format rather than be maximised for a stronger sensation.
What format suits a spicule product?
Spicules are typically used in a booster or periodic treatment format with defined usage frequency. This protects tolerability and sets clear consumer expectations, and it fits well alongside a daily routine as a step that makes other products more effective.
How long does it take to develop a spicule product?
With a pre-qualified formulation base as a starting point, a white-label route is typically 2 to 3 months. An individual new development is usually 3 to 6 months, depending on stability testing, tolerability iteration, regulatory preparation and packaging availability.
