Grade Our Honesty
A public honesty file on the Face Introducer. You grade it.
The pattern we are trying to break
You have been told a device "transforms" before. You have been promised "clinical" results that did not arrive. You bought a piece of hardware that sat on a shelf after the third week because the marketing was louder than the mechanism.
We are not going to pretend that pattern does not exist. It does. We work in the same category that produced it.
So before we ask you to use the Face Introducer, we are publishing what it does, what it does not do, and where it falls short. You decide whether we told the truth. That grade is the only metric that matters to us right now.
What the Face Introducer is
Three modalities. Named plainly. No fourth one added to round out the list.
EMS (electrical muscle stimulation).
Engages the facial muscles beneath the skin. With consistent use, it is associated with improved appearance of muscle tone and a visible lift effect. Individual results vary, and we make no promise about yours. It is not a substitute for in-office muscle-targeting procedures. Results depend on continued use.
Microcurrent.
Delivers a low-level electrical current, measured in microamperes. It is gentle by design — you may barely feel it, and that is the intended sensation rather than a fault. Microcurrent is commonly associated with the appearance of improved facial muscle tone over time; individual results vary, and this is a description of the category, not a promise about your face. That sentence is deliberately not dressed up as a literature claim: we hold no peer-reviewed study on a consumer microcurrent device of this class, so we cite none. Much of the published work in this area used clinical-grade equipment running at materially different parameters, and borrowing it to sell you a handheld would be the exact move this page exists to refuse. If we ever have a citation that fits the device, it will appear here. It is not a deep-tissue intervention.
Thermal (warming).
Warms the skin surface during a session. The function supports comfort and helps conduct topical products into the skin. It is a session aid. It is not a fat-reduction treatment. It is not a resurfacing treatment. It will not remodel deep tissue.
That is the full list. There is no LED. There is no red light. There is no light therapy of any kind on this device. The indicator light on the unit is a mode indicator. It tells you which modality is active. It is not a treatment.
What the Face Introducer is not
We would rather you read this section before you buy than after.
- It is not a light therapy device. If you are looking for at-home LED or red light therapy, this is the wrong product. We will not pretend otherwise.
- It is not an ablative laser. It will not remove skin in measured layers. It will not produce laser-grade resurfacing.
- It is not microneedling. It does not create controlled micro-injuries. It does not trigger a wound-healing cascade.
- It is not radiofrequency skin tightening. It does not deliver RF energy to deeper tissue layers.
- It is not a deep chemical peel. It does not apply acid formulations at clinical strength.
- It is not a replacement for prescription skincare. Topical retinoids, prescription actives, and dermatologist-supervised regimens are a different category. The Face Introducer sits beside them. It does not replace them.
- It will not produce permanent structural change. Any visible effect from EMS or microcurrent is maintained through continued use. Stop using the device and the effect attenuates. That is the nature of the modalities. We will not sell you permanence that the physics does not support.
If you are looking for any of the above, a dermatologist's office is the right call. We will tell you that directly.
The guarantee, restated
Every Face Introducer ships with a 30-day money-back guarantee.
If the device does not perform as described in this honesty file, the return is yours. No restocking fee. No "we are sorry you feel that way." No email loop designed to time out the return window.
The language on the guarantee page is the same language used here. We did not write one version for marketing and another for the fine print. There is one version.
The invitation
Read the file. Check it against the product page. Check it against the manual. Check it against your own knowledge of what these modalities can and cannot do.
Then tell us where we lied.
If a claim here does not match the device, we want to hear about it. If a limit is overstated, we want to hear about it. If something we left out should have been included, we want to hear about that too.

Subject line: Grade
We read every message. We respond to every grade.
The point of this exercise is not to sell you a device. The point is to find out whether a brand can publish its own limits and still be trusted. You are the judge. We are the record.
