Skin conditions such as acne, rosacea, and signs of ageing can be challenging to manage with topical treatments alone. LED light therapy offers a gentle, non-invasive approach that uses specific wavelengths of light to reduce inflammation, support healing, and promote skin health. At South Yarra Dermatology, we use this evidence-based treatment to address a range of concerns, either alone or alongside other therapies.
LED (light-emitting diode) therapy uses specific wavelengths of light to trigger biological responses in the skin. Unlike lasers, which emit a concentrated single wavelength at high intensity, LEDs deliver broader, gentler light that penetrates the skin to varying depths depending on the wavelength. This light energy is absorbed by skin cells, reducing inflammation, stimulating healing, destroying certain bacteria, and promoting cellular activity.
The treatment is entirely non-invasive. Light is directed at the skin without contact, heat, or discomfort. Many patients find the experience relaxing, resting comfortably while LED panels or devices deliver the therapeutic wavelengths. Sessions typically last 15 to 30 minutes and can be repeated regularly as part of a comprehensive skin care plan.

LED light therapy is a versatile, non-invasive treatment that uses specific wavelengths of light to target various skin concerns at the cellular level. Different light wavelengths penetrate the skin to varying depths, triggering natural biological responses that can reduce inflammation, stimulate collagen production, and promote healing. LED light therapy can address a range of skin concerns, such as:
LED light therapy offers benefits from reducing inflammation and acne to supporting skin rejuvenation and healing. Before recommending treatment, we take time to understand what you hope to achieve and how LED light therapy might fit into your skincare goals. This helps us determine the appropriate wavelengths and treatment approach for your skin.
LED light therapy is completely non-invasive, with no needles, heat, or discomfort involved. Most people find the treatment relaxing, experiencing only a gentle warmth as the light penetrates the skin.
Different wavelengths of light address different issues, from acne and inflammation to signs of ageing and wound healing. This versatility allows for customised treatment based on your specific concerns.
You can return to your regular activities immediately after treatment with no redness, peeling, or side effects. This makes it easy to fit into any schedule without disrupting your routine.
LED therapy works by stimulating your skin’s own cellular activity and natural repair mechanisms rather than causing controlled damage like some other treatments. This encourages healthier skin function from within.
LED therapy complements other skincare treatments and can be used alongside procedures like chemical peels or microneedling to support healing and enhance results. It’s a valuable addition to comprehensive skincare plans.
The gentle nature of LED therapy makes it appropriate for sensitive skin types that may not tolerate more aggressive treatments. It’s also safe for various skin tones when performed by experienced practitioners.
We begin with a consultation to understand what you hope to achieve and assess whether LED light therapy is right for your skin concerns. From there, we’ll discuss the appropriate wavelengths and treatment approach based on your needs.
Before treatment, arrive with clean skin free from makeup, sunscreen, and skincare products so the light can penetrate effectively. If you’re using any photosensitising medications or skincare ingredients, inform us during consultation as these can affect how your skin responds. Always let us know of any medications you’re taking, recent illnesses, or changes in your health since your consultation.
During treatment, you’ll rest comfortably beneath or in front of the LED panels while wearing protective eyewear. Sessions typically last 15 to 30 minutes, with minimal warmth at most. Afterwards, you can resume normal activities immediately with no redness, sensitivity, or downtime. Makeup can be applied straight away if desired.
LED light therapy is particularly suitable for sensitive skin that doesn’t tolerate more aggressive treatments, or if you prefer a gentle, relaxing approach to skin improvement without disruption to your daily routine.
If you’re looking to address acne, redness, inflammation, fine lines, or overall skin health, book a consultation at South Yarra Dermatology to discuss whether LED light therapy is right for you.
No, LED and laser treatments are fundamentally different despite both using light. Lasers produce intense, focused beams that create heat and controlled tissue damage, while LEDs emit broader, gentler light at lower intensities without causing tissue damage or discomfort.
Laser treatments often involve downtime and carry more risk but can produce dramatic results relatively quickly. LED therapy is completely comfortable with no recovery period, providing subtle improvement gradually with minimal risk. The applications differ as well: lasers can remove lesions and resurface skin, while LED primarily influences cellular activity and inflammation.
Red and blue light work through different mechanisms and address different concerns. Red light penetrates deeper into the skin where it enhances cellular energy production, supports collagen synthesis, improves circulation, and reduces inflammation. It is used primarily for rejuvenation, anti-ageing, rosacea management, and healing support.
Blue light has shallower penetration and is absorbed by compounds produced by acne bacteria, generating reactions that destroy the bacteria. It is used primarily for acne treatment. The wavelengths can be used separately or combined depending on individual needs.
LED light therapy involves no sensation beyond seeing coloured light and perhaps feeling slightly warm from proximity to the device, though even warmth is typically minimal. There is no heat, no tingling, no discomfort. Many people find LED sessions remarkably relaxing precisely because there is no sensation requiring tolerance.
The complete lack of discomfort makes LED therapy appealing for people anxious about treatments or those with sensitive skin. After treatment, there is no lingering sensation, no tenderness, and nothing to indicate treatment occurred.
Individual LED therapy sessions typically last 15 to 30 minutes, though duration varies based on the device being used, the wavelength and intensity of light, the area being treated, and the protocol for your particular concern. Full-face treatment might take 20 minutes, while targeted treatment of specific areas could be shorter.
The actual light exposure comprises most of the session, with minimal time needed for preparation (removing makeup and cleansing the skin). Many people schedule sessions during lunch breaks or between other commitments.
Treatment frequency depends on the concern being addressed and whether you are in an initial treatment phase or maintenance. For acne, protocols often recommend two to three sessions per week for several weeks initially, then reduced frequency for maintenance. For rosacea, weekly or bi-weekly sessions might be suggested initially. For rejuvenation and general skin health, frequency varies widely based on individual goals.
Consistency matters more than intensity. Regular sessions at whatever frequency you can sustain produce better results than sporadic intensive periods followed by long gaps.
Results from LED therapy develop gradually rather than appearing after one or two sessions. For acne, you might notice reduced breakouts and less inflammation after several weeks of consistent treatment (typically after 6 to 12 sessions). For rosacea, decreasing redness may become apparent after several weekly treatments. For rejuvenation, subtle improvements in texture, tone, and overall appearance develop over weeks to months of regular treatment.
The timeline depends on the severity of your concern, how well your skin responds, treatment frequency, and whether you are combining LED with other treatments. The gradual nature of results requires patience and commitment.
Yes, one significant advantage of LED therapy is its suitability across all skin types, including very dark skin tones. Unlike lasers or IPL that target melanin and can cause pigmentation problems in darker skin, LED light does not target melanin or create heat injury, eliminating the primary risks for darker complexions.
The therapy works through photobiomodulation (influencing cellular activity) rather than through selective photothermolysis (destroying specific targets), which means skin colour does not affect safety or efficacy. People of all ethnic backgrounds and skin tones can safely benefit from LED therapy.
No, results from LED therapy are not permanent and are maintained only with ongoing treatment. The therapy provides biological stimulation that lasts only while treatment continues. When you stop, the beneficial effects gradually diminish as cells return to their baseline state.
This does not mean LED therapy is not worthwhile. Many beneficial treatments require ongoing use rather than providing permanent results. Most people who benefit from LED therapy incorporate it into ongoing skin care routines, viewing it as a maintenance practice rather than a one-time intervention. The need for ongoing treatment means considering whether you are willing and able to commit to regular sessions long-term.
Maintaining LED therapy results requires ongoing regular treatments, as benefits diminish when therapy is discontinued. The specific maintenance schedule depends on your individual response. Some people maintain results with monthly sessions, while others need more frequent treatment.
Beyond continued LED therapy, supporting results involves comprehensive skin care, including appropriate products, diligent sun protection, healthy lifestyle practices, and managing triggers if treating conditions like rosacea or acne. Think of LED therapy as one component of ongoing skin care rather than a solution that works in isolation.
