Why this happens
It isn’t effort. It’s structure.
Collagen is the elastic
Skin holds its shape because of collagen — the elastic framework inside it. Over time the body makes less of it, and the skin slowly loses the tension that used to pull it back into place.
The upper arms show it first: thin skin, constant movement, almost nothing underneath to take up slack.
That is why creams and workouts rarely touch it. The change is inside the skin — not on it, and not under it.
How InfraLux works
Two things happen in the same ten minutes
One works on the skin. One works on what you put on it.
1
The light works on the skin
660 nm and gentle warmth — the wavelength with the most published skin research. Runs with or without serum.
2
The pulses work the serum in
Gentle micro-pulses turn a passive layer of serum into an active application instead of leaving it on the surface.
3
The serum is built to move
Water-based, low molecular weight. No oils, no silicones — nothing that seals the skin off from the device.
Why InfraLux
Built around one decision: that you’ll still use it in week six
1
The wavelength with the research behind it
Not just “red light.” 660 nm — the specific wavelength with the most published work for skin.
2
Sized for the body, not the face
Almost every device on the market is a face device. This one is shaped for the upper arm and works the same way on the stomach, thighs and neck.
3
A routine that survives real mornings
Ten minutes, cordless, with the dose sealed in single ampoules. Nothing to measure, nothing to decide, nothing to get wrong at 7am.
The science
The research behind red light
Two published trials on the wavelength range InfraLux is built around.
Double-blinded, split-face · 76 participants
More collagen and elastic fibres under the microscope
Skin treated with red LED light measured up to 19% higher in elasticity, with more collagen and elastic fibres in the tissue samples.
Both trials studied red-light photobiomodulation in general, not the InfraLux device. We cite them as independent research on the wavelength range InfraLux is built around.
What to expect
Skin moves slowly. Here is the honest order.
Week 1
Nothing announces itself.
The week most women almost stop.
Week 2
It feels different before it looks different.
Less tight by evening.
Week 4
The light catches it differently.
Fine creasing softens first.
Week 8
You stop checking.
Not that it is gone. That you forgot to look.

I stopped putting my hand on my arm
I did not know I was doing it until I read a description of it. Six weeks in I caught myself reaching for a plate and just bringing my arm down. That was the moment, not the mirror.

A year of collagen powder, and this was the thing that moved
Reading that it was the skin itself was almost a relief. The ampoules turned out to be the point.

Slower than I wanted, but it did come
Around week five the crepey look under the arm softened. Not dramatic, but the first thing in four years that did anything.

Two kinds of routine
Most skincare is applied. Almost none of it is delivered.
A cream alone
Passive application
- Supports hydration and surface feel
- Sits where you leave it — on the surface
- Oil- and silicone-based formulas seal the skin
- No effect on how the product is applied
InfraLux + serum
An active routine
- 660 nm red light works on the skin itself
- Micro-pulses turn application into delivery
- Water-based serum, built to move with the device
- Ten minutes, designed to be repeatable daily
A good cream is not a mistake — hydration matters. Red light adds a different kind of step: one aimed at the skin’s structure, not its surface.

Use it for 90 nights. If your arms do not look firmer to you, every penny comes back.
Before you order
The questions women ask, in the order they ask them
Is my skin already too thin for this?
Thin skin is not damaged skin — it is skin with less structure than it used to have. Nothing here is aggressive. No needles, no suction, no heat beyond a warm hand. If anything, thinner skin is the reason to skip the harsh options, not this one.
Will it build, or is it four hours of looking better?
Surface hydration is what a cream does on its own, and you are right to be suspicious of it. That is why the light and the serum are sold together: one works on the skin, the other decides whether what you apply gets past the surface at all.
I have tried every firming cream and nothing worked.
That is experience, not scepticism, and a better promise would not answer it. The only thing that answers it is a different place of action. A cream is limited by passive application. This changes the application, not the promise.
Doesn’t this only work on the face?
Almost every device on the market is a face device, which is a fair reason to be suspicious. This one is sized for the upper arm and works the same way on the stomach, thighs and neck.
How long before I see anything?
Nothing in week one. In week two it feels different before it looks different. Around week four the light catches it differently. Around week eight is when women tell us they stopped checking.
Is it safe with my medication?
It is a cosmetic device used on the outside of the skin and does not interact with anything you take. Your own doctor knows your history, so ask them if you have any doubt.
Am I going to give up after two weeks?
The quiet one, and the most honest. It is why the session is ten minutes and why the dose comes sealed. Nothing to measure, nothing to decide, nothing to get wrong at 7am.
