Red light and EMS get sold together as slimming. They do different things, and neither is slimming
By the team at New Age Spa · Updated 1 September 2026
These two treatments sit next to each other on most body menus, ours included, and the pairing invites a conclusion neither one supports. One passes current through muscle. The other shines light on skin. Neither removes fat.
Red light is the gentlest thing we offer and it is genuinely pleasant, which is exactly why it gets oversold. This page is about what it is reasonable to expect from it, in descending order of how confident we are.
The two treatments, side by side
| Red light therapy | EMS | |
|---|---|---|
| What reaches you | Light at particular wavelengths, absorbed by cells | Electrical current, which makes muscle contract |
| What you feel | Warmth, and nothing else. Most people find it restful | Strong involuntary contractions |
| Best supported use | Skin quality and calming irritated skin | Muscle tone in a specific area |
| Fat removal | No | No |
| Who cannot have it | Few people, but photosensitising medication matters | Anyone with a pacemaker or implanted device — absolutely |
The contraindications for EMS are strict and are set out in full on the EMS page. Do not assume that because red light suits nearly everyone, the treatment sold beside it does too.
What red light is reasonably expected to do
- Skin quality and calmer skin. This is where the case is strongest, and it is why the facial version exists as its own service.
- Comfort after other treatments. It is a sensible thing to book after something more aggressive, precisely because it asks nothing of the skin.
- A general sense of recovery. Widely reported, harder to measure, and we would rather say so than quote a study at you.
- Weight, cellulite, inches lost. No. If a page promises those from light, it is selling past the evidence.
Why we still think it is worth booking
Because the risk is close to zero and the session is forty-five minutes of doing nothing. That is a real proposition on its own terms, and it does not need a fat-loss claim propped underneath it. The full-body version includes the face; the facial version is the same idea concentrated where the evidence is best.
What it will not do is substitute for treatment that reaches deeper. If the concern is texture, scarring or pigment, light alone is not the answer — that work is described in what microneedling is actually for.
Before you book
- Tell us about photosensitising medication. Some antibiotics, acne medication and other drugs change how skin responds to light.
- Eye protection is worn. Not optional, and not negotiable because the light feels mild.
- It is cumulative. One session is a nice forty-five minutes. Any effect worth noticing comes from a run of them.
- Nothing about it is dramatic. If you want a visible change from one appointment, this is the wrong booking and we will tell you.
What we will not do
- Sell red light as fat loss, inch loss or a cellulite treatment.
- Package it with EMS and let the pair imply a slimming result.
- Treat over a mole or lesion that is changing, or an area under investigation.
- Recommend it in place of a treatment that would actually address your concern.
See a doctor if
You take medication that increases light sensitivity, have a photosensitive condition such as lupus, are pregnant and unsure, or have a mole or lesion inside the area that is changing. Also if you are pursuing weight loss for health reasons, which is a medical conversation.
