Light-emitting diode (LED) light therapy is a popular modern skin treatment. It uses specific wavelengths of light to help stimulate the skin’s regenerative processes, leading to visible improvements in skin tone and texture.
If you’re looking for a non-surgical way to revitalise your skin, LED light therapy might be the right fit for your needs. In this blog, we explore LED light therapy benefits, potential side effects and who it’s best suited for.
How does LED light therapy work?
LED light therapy uses coloured wavelengths to stimulate the skin’s natural healing processes and boost rejuvenation. This can lead to a clearer, smoother and more balanced complexion over time.
Here’s what typically happens during a session:
- Cleansing — The skin is cleared of makeup, oil and debris.
- Eye protection — You’ll wear goggles to safeguard your eyes from the bright light.
- Light application — An LED device is placed over the treatment area. It emits light, which remains on the skin for up to to 30 minutes, depending on your unique objectives and needs.
- Aftercare — Once the session ends, your dermal clinician may recommend applying a broad-spectrum sunscreen with at least SPF 30, as your skin can be more sensitive to sunlight following treatment. You’ll also receive tailored aftercare instructions to support proper healing and help you manage any temporary side effects.
The benefits of LED light therapy develop gradually. Multiple sessions are typically needed to achieve and maintain results. The exact number of treatments will vary based on your skin type, concerns and treatment objectives.
The different kinds of LED light
LED light therapy uses various colours of light, with each wavelength targeting a specific skin issue. Below is a breakdown of what each one does:
- Red
Red LED light penetrates deeply into the skin. The benefits of red LED light therapy have been widely explored in clinical settings, including its potential role in supporting wound healing, reducing signs of sun damage and addressing inflammatory skin conditions. Some studies have also explored its use in treating certain pre-cancerous and non-melanoma skin lesions as well as chronic conditions such as warts and photodamage.
- Blue
Blue LED light targets the uppermost layers of the skin, making it especially useful for skin concerns that affect the epidermis. Blue LED light therapy benefits include helping to manage blemishes and breakouts. It may also support the treatment of chronic skin conditions like eczema, psoriasis and atopic dermatitis.
- Yellow
The benefits of yellow LED light therapy include soothing the skin and reducing visible signs of irritation. It may also help with redness, swelling and pigmentation-related concerns and minimise the appearance of expression lines.
The facial benefits of LED light therapy
Though individual results may vary, generally, LED light therapy can help with:
- Boosting collagen and elastin production to soften facial creases
- Smoothing overall skin tone and texture
- Calming redness and soothing inflammation
- Helping to manage blemishes and prevent breakouts
- Reviving dull or tired-looking skin
LED light therapy can be performed on all skin tones and types. It doesn’t rely on ultraviolet (UV) light, so it won’t burn the skin.
Common side effects and risks
Like any skin treatment, LED light therapy can trigger side effects and reactions, which will be discussed in detail during your initial consultation. These reactions are typically mild and temporary, but it’s essential to closely monitor your skin following treatment.
Possible side effects may include:
- Redness
- Increased inflammation
- Rash
- Mild discomfort or pain
If any of these symptoms persist or worsen, consult your general practitioner promptly. Your dermal clinician will also provide guidance on how to care for your skin post-treatment.
Contraindications to be aware of
Individuals should avoid LED light therapy or seek medical clearance from their physician first if they:
- Are pregnant or nursing
- Are diagnosed with epilepsy
- Have had recent facial volume restoration treatments
- Have certain thyroid conditions
- Have a history of skin cancer
- Have systemic lupus erythematosus
- Are taking photosensitising medications
- Have diseases that affect the retina of the eye
This is why every LED light therapy session should begin with a detailed consultation with a qualified dermal clinician. During this appointment, they will review your medical history and evaluate your skin to ensure that the treatment is safe and appropriate for you.
