What Are Bio-Soluble Micro-Points? Gentle Skincare For Serum Absorption
If you have seen “bio-soluble micro-points” online, the idea may sound futuristic. But the concept is simple: tiny, water-soluble skincare points help a serum move beyond the skin’s surface, then dissolve instead of leaving metal behind.
This guide explains what they are, how to use them, and how they differ from metal derma rollers.
Quick answer
Micro-points are:
- Not metal needles. They are tiny points made from skin-friendly ingredients.
- Designed to dissolve. When they touch moisture on the skin, they soften and release their ingredients.
- Made for at-home use. They are meant to support serum application without puncturing living skin.
The complete IROLLING routine is available in the Bio-Soluble Micro Infusion System.
What are bio-soluble micro-points?
Bio-soluble micro-points are tiny skincare “tips” made from ingredients such as sodium hyaluronate, peptides, and sugar-based ingredients. They are arranged on a single-use roller head.
When you roll the device over clean, dry skin, the points help guide the serum beyond the outermost surface layer. Then they soften, dissolve, and disappear.
Think of it like this:
- Roll the micro-point head over the skin.
- Apply the serum.
- Seal with a barrier-supporting mask.
IROLLING pairs the roller with a PDRN serum and a five-ceramide mask so the routine is complete.
Why serum alone may not be enough
Healthy skin is excellent at keeping things out. Its outer layer works like a protective wall. That is good for barrier health, but it also means some skincare ingredients can sit near the surface when they are simply applied on top.
Scientists often refer to the 500 Dalton rule. In simple terms, many larger ingredients have difficulty crossing intact skin. This does not mean the ingredients are useless. It means delivery matters.
Micro-points were designed to help with that problem without hurting the living layers of skin.
What is inside the roller head?
IROLLING’s micro-point roller head includes:
| Ingredient group | What it does | Why it matters |
|---|---|---|
| Copper tripeptide-1 | Supports the skin’s natural renewal processes. | Helps skin look smoother and firmer. |
| Sodium hyaluronate and trehalose | Help form the water-soluble points and support hydration. | Help skin feel plump and comfortable. |
| Adenosine | A skin-conditioning ingredient. | Helps refine the look of skin texture. |
The full system also includes a PDRN serum and a five-ceramide mask.
How bio-soluble micro-points work
A micro-point roller is designed to create temporary pathways through the skin’s outer layer. The points then soften as they touch moisture and release their ingredients.
This is different from metal microneedling:
- Metal rollers use solid needles to pierce the skin.
- Micro-points are designed to work on the outer layer, not puncture living skin.
- Metal needles stay solid; bio-soluble points soften and dissolve.
- IROLLING’s roller head is single-use.
In short, IROLLING is designed to support serum absorption without puncturing living skin.
Why point shape matters
The shape of each point affects how well it touches the skin, how evenly it dissolves, and how predictable the routine feels.

Fig. 2: IROLLING bio-soluble micro-points, designed for a more uniform tapered shape.
Published research on dissolving micro-points has found that shape can affect how well the points enter skin and dissolve. One study reported that cone-shaped arrays had a 97.8% insertion ratio and dissolved more completely than several other shapes after 20 minutes.
For a consumer routine, the takeaway is simple: a more uniform point shape helps the product feel more consistent.
Serum alone vs serum with micro-points
IROLLING also compared serum placement with and without the micro-point roller.

In everyday terms, the comparison is meant to show the difference between leaving much of a serum on the surface and helping it move beyond the outer layer. These are IROLLING-supplied visualizations, not a promise of individual results.
Metal roller vs IROLLING bio-soluble micro-points
| Traditional metal roller | IROLLING bio-soluble micro-points | |
|---|---|---|
| Material | Metal needles, often stainless steel or titanium. | Water-soluble skincare ingredients. |
| How it works | Creates punctures; serum is applied afterward. | Creates temporary surface pathways while the points soften and dissolve. |
| Contact with living skin | Depends on needle length, pressure, and technique. | Designed to avoid puncturing living skin. |
| Sensation | Can feel sharp or uncomfortable. | Designed for a gentle at-home experience. |
| Hygiene | Reusable unless properly cleaned and replaced. | Single-use roller head. |
| Routine | Tool only. | Roller + PDRN serum + ceramide mask. |
At-home energy devices can be harder to judge. Some may not reach a useful energy level, while stronger devices belong in professional settings. IROLLING avoids that issue by focusing on ingredient delivery and consistency rather than heat, light, or current.
Why consistency matters
Skin aging does not happen overnight. Collagen, hydration, firmness, and texture change slowly. IROLLING’s philosophy is not “one aggressive treatment.” It is:
Single-session support × frequency = cumulative skin improvement.
A gentler routine that can be repeated consistently may be more realistic than occasional aggressive treatments. Follow the official How to Use guide for the recommended sequence and frequency.
What the 28-day test looked at
IROLLING’s 28-day cosmetic-use test studied the complete three-step system in 30 people.
The study looked at:
- Hydration and water loss.
- Visible redness markers.
- Skin elasticity and firmness.
- Smoothness, gloss, and visible texture.
- The look of fine lines and wrinkles.
Participants also reported improvements in perceived hydration, softness, elasticity, smoothness, fullness, radiance, and overall satisfaction. No irritation or allergic reactions were observed in the test group. Individual results vary.
How IROLLING refined the product
IROLLING did not stop at the first version.
The team originally selected a 3M medical-grade adhesive for its safety documentation. After users said the odor was unpleasant, IROLLING worked with its domestic supply chain to create an adhesive that still met safety standards but had no unpleasant smell.
The team also improved shelf-life validation. Instead of defaulting to a long shelf-life claim, IROLLING used accelerated testing plus real-time validation. As data accumulated, the stated shelf life increased from 24 to 30 months.
Who should be careful?
Bio-soluble micro-points may be helpful if you want a gentler alternative to metal rollers and a complete at-home routine.
Do not use on broken, irritated, sunburned, or recently treated skin. If you have active acne, eczema, psoriasis, rosacea, a skin infection, or are under dermatological care, ask a qualified professional first.
If you use the roller near the eye area, use very light pressure and avoid the eyelid or direct eye contact.
FAQ
Are bio-soluble micro-points the same as microneedling?
No. Medical microneedling uses needles to puncture the skin. Bio-soluble micro-points are water-soluble points designed to support delivery through the outer skin layer and dissolve with moisture.
Do they hurt?
The system is designed for comfort and does not require numbing. Sensation varies, but it is intended to feel gentler than metal microneedling.
Do the points really dissolve?
Yes. They are designed to soften and dissolve as they contact moisture. That is why the roller head is single-use.
Can I use them around my eyes?
IROLLING’s micro-point roller may be used around fine-line areas with very light pressure. Avoid the eyelids and direct contact with the eyes.
How often should I use it?
Follow the official How to Use guide. The routine is designed around scheduled use, not daily aggressive rolling.
Is this a substitute for injectables?
No. IROLLING is an at-home cosmetic skincare system. Injectables are medical procedures and should be discussed with a qualified medical provider.
