LED light therapy uses specific wavelengths of visible and near-infrared light to influence how skin cells behave. It sits at the gentle end of the treatment scale. Where a laser works by creating controlled injury that the skin then repairs, LED does not damage tissue at all, which is why it is often used as a supporting treatment rather than a standalone fix.
At our Kent Town clinic in Adelaide, LED light therapy is most often used alongside other treatments, or as a course in its own right for people who want to support skin recovery without downtime.
How LED light therapy works
Light at particular wavelengths is absorbed by the mitochondria inside skin cells. Mitochondria generate the energy a cell needs to do its work, and the theory behind LED is that supplying this specific light energy helps them do that more efficiently. This process is sometimes referred to as photobiomodulation. Cells with more available energy can carry out repair and renewal processes more readily.
The wavelength determines how deep the light travels and therefore what it influences.
- Blue light stays shallow and is used mainly for its effect on the bacteria involved in acne
- Yellow and amber light targets redness and may help calm reactive or rosacea-prone skin
- Red light reaches the dermis and is associated with collagen activity and reduced redness
- Near-infrared travels deepest and is generally used to support healing and reduce inflammation
Sessions often combine wavelengths depending on what is being treated. A panel used for post-treatment recovery will be configured differently to one being used for active breakouts, even though the device is the same.
Dose matters as much as wavelength. Too little light and there is no measurable effect; beyond a certain point, more exposure does not add benefit. This is why session length is set rather than left open ended, and why lying under a panel for longer is not an advantage.
What it is commonly used for
The conditions treated depend on which wavelengths are used and how the course is structured.
- Supporting recovery after laser, skin needling or chemical peel treatments, where reducing inflammation matters
- Active acne, using the blue wavelength alongside other acne management
- Redness and irritation in reactive skin, including as part of a broader rosacea treatment plan
- Post-procedure healing where the skin barrier has been disrupted
- Mild pigmentation concerns, typically as an adjunct to more targeted treatments
- As a maintenance treatment between more intensive sessions
Being realistic about the scale of change matters here. LED is a supportive treatment.
It can improve how skin looks and feels over a course, particularly redness and recovery time, but it does not resurface skin or address structural concerns such as deep scarring or significant laxity. For those, the clinic would usually discuss Laser Genesis skin rejuvenation in Adelaide or another resurfacing option instead. If your main concern is uneven tone rather than texture, the clinic’s page on the best pigmentation removal options covers what tends to work better for that goal.
LED for acne specifically
Blue light is the wavelength most associated with acne. The bacteria involved in inflammatory acne produce compounds that absorb light in the blue range, and exposure to it can reduce their numbers on the skin. Red or near-infrared light is often used in the same session to address the inflammation that comes with active breakouts.
What LED does not do is address the other drivers of acne, such as excess oil production, hormonal factors or blocked follicles. That is why it is generally used as one part of an acne plan rather than the whole of it, and why it tends to be discussed alongside acne treatment options in Adelaide rather than instead of them.
For people who cannot tolerate certain topical treatments, or who want to reduce inflammation without adding another product to their daily regimen, it can be a useful addition. Response varies considerably between individuals and it is not effective for every presentation of acne.

|---|---|---|---|
| Energy level | Low | High | Moderate to high |
| Damages tissue | No | Yes, deliberately | Yes, targeted |
| Downtime | None | Days to weeks | Hours to days |
| Main use | Recovery, inflammation, acne | Resurfacing, scarring | Pigment and vessels |
| Course length | Six to ten sessions | One to three | Three to six |
What a session involves
You lie under a panel of light for roughly 10 to 20 minutes with eye protection in place. There is no heat to speak of and nothing touches the skin. Most people find it uneventful, and some fall asleep.
There is no recovery period afterwards. Makeup can go straight back on and normal activities continue immediately, which is part of why it pairs well with other treatments on the same day.
How many sessions are typically needed
LED is cumulative rather than immediate. A single session is unlikely to produce visible change on its own. Courses commonly run to somewhere between six and ten sessions, often two per week initially, then spaced further apart for maintenance.
Where LED is being used to support recovery after another treatment, the timing is different again and is usually scheduled around that treatment rather than as a separate course.
Maintenance is worth thinking about before you start. The changes LED produces rely on ongoing cellular activity rather than a structural alteration, so they fade if treatment stops entirely.
People who found a course useful often continue at a reduced frequency, perhaps monthly, rather than treating intensively and then stopping. Whether that is worth the ongoing time and cost is a personal decision, and it is a fair question to raise at consultation before committing to a first course.
How it differs from laser and IPL
People often group these together because they all involve light, but they work in different ways and are chosen for different reasons.
Laser produces a single coherent wavelength at high energy, concentrated enough to heat or vaporise tissue in a controlled way. That is what makes resurfacing possible, and also what creates downtime. Treatments such as CO2 laser resurfacing work by creating this controlled thermal injury at depth. IPL uses a broad spectrum of light filtered to target particular structures such as pigment or blood vessels, again with enough energy to affect them directly.
LED sits apart from both. The energy is far lower and the intent is not to damage anything. Nothing is heated, nothing is broken down, and no controlled injury is created.
That is the reason there is no downtime, and equally the reason it will not produce the kind of change resurfacing does. Choosing between them is a question of what you are trying to achieve rather than which is better.
Getting the most from a course
Because the effect is cumulative, consistency matters more than intensity. A few practical things make a difference.
- Attend sessions at the spacing recommended rather than clustering them when convenient
- Arrive with clean skin, since makeup and sunscreen sit between the light and the skin
- Keep the rest of your skincare regimen stable through the course so you can tell what is doing what
- Maintain sun protection throughout, particularly through an Adelaide summer
- Tell the clinic if you start any new medication mid-course, as some affect light sensitivity
LED is a supporting treatment, not a resurfacing one. It can help recovery, inflammation and redness. It will not remove deep scarring or significant laxity.
Risks and things to consider
LED is non-ablative and generally well tolerated, but no treatment is without risk. Temporary redness, dryness or mild headache can occur. Eye protection is required throughout, as prolonged exposure to bright light without it can cause eye strain or damage.
- Some medications and supplements increase light sensitivity and may make treatment unsuitable
- Certain skin conditions can flare with light exposure, so disclose your full history at consultation
- People with a history of light-triggered migraine may prefer to avoid it
- Pregnancy is generally a reason to postpone
- Recent sun exposure may mean rescheduling, which matters in South Australia’s UV conditions
Outcomes vary between individuals and are not guaranteed. An assessment with a registered health practitioner is the only way to know whether it suits your skin and what to expect. General information about skin health is available from healthdirect and the Better Health Channel.
Cost
Pricing depends on whether LED is booked as a standalone course or added to another treatment, and rates are listed on our pricing page. Those figures are indicative and your fee is confirmed at consultation.
Common questions
Is LED light therapy the same as a sunbed?
No. Sunbeds emit ultraviolet radiation, which damages skin and raises skin cancer risk.
LED devices used in clinics do not emit UV. They are different technologies aimed at opposite outcomes.
How does clinic LED compare to an at-home mask?
Clinic devices deliver far higher light output across a larger area, so the dose actually reaches a level associated with a response. Home masks are typically a fraction of that power, which is why results from them are usually underwhelming and slow.
Can it be combined with other treatments on the same day?
Frequently, yes. It is often used immediately after needling or a peel to support recovery, and the sequencing is planned as part of your treatment plan.
When might results become noticeable?
Redness and irritation often respond within the first few sessions. Changes relating to collagen are slower and are usually assessed across a full course rather than week to week.
Does it hurt?
There is no needle and no heat to speak of. Most people describe the light as bright but the session itself as uneventful.
Is LED light therapy safe for all skin types?
LED does not target melanin the way some laser and IPL treatments do, which means it can typically be used across a wider range of skin types than some light-based alternatives. Your practitioner will assess suitability during consultation, including any medications or skin conditions that may affect treatment.
Does LED light therapy actually work?
Published research supports its use for wound healing, inflammatory acne and post-procedure recovery, though the quality and size of studies varies. It is not a standalone solution for most concerns, which is why it is typically part of a broader treatment plan rather than the whole of one. Your practitioner can discuss the evidence relevant to your situation during a consultation.
How long does each session take?
Most sessions run for 10 to 20 minutes under the panel, depending on the wavelengths used and the treatment goal. There is typically no preparation or downtime involved, so the total appointment is usually under 30 minutes.
Next steps
LED works better as part of a plan than in isolation, so the useful first step is working out what your skin actually needs. You can read more about Healite II LED light therapy at our Adelaide clinic, or book a consultation to discuss whether it suits you.
An assessment works out whether LED belongs in your treatment plan and what to pair it with. Book a consultation at our Kent Town clinic in Adelaide, or call the clinic on (08) 8239 0431 to talk it through first.
