Dermalux LED Light Therapy: Your Complete Guide

Light-emitting diode (LED) therapy is one of the most asked-about treatments at my studio in Brighton & Hove. Clients want to know how it works, whether it suits their skin, and what results to expect. As someone who uses Dermalux LED therapy daily, I want to share what this technology can genuinely offer.

This guide covers the science behind LED phototherapy, the 3 wavelengths Dermalux uses, and what realistic results look like across different skin concerns.

How Dermalux LED phototherapy works

Photobiomodulation converts light into cellular energy

Dermalux LED therapy delivers precisely calibrated wavelengths of light that stimulate natural cellular processes. This mechanism, called photobiomodulation, occurs when cells absorb light energy and convert it into adenosine triphosphate (ATP) — the fuel that powers repair, regeneration, and healing.

Think of it as giving your skin cells a targeted energy boost, allowing them to function at their optimal level.

NASA research first proved LED accelerates cell growth

NASA scientists in the 1990s discovered that specific red light wavelengths could accelerate plant growth in space — and then turned their attention to human tissue. A landmark study published in the Journal of Clinical Laser Medicine & Surgery↗ documented that "light-emitting diodes (LED), originally developed for NASA plant growth experiments in space show promise for delivering light deep into tissues of the body to promote wound healing and human tissue growth."

The research found that LED produced 140–200% increases in cell growth in mouse-derived fibroblasts and "increases in growth of 155-171% of normal human epithelial cells."

Professional-grade Dermalux outperforms home devices

Not all LED devices deliver equal results. Dermalux is a professional-grade system with meaningful advantages over consumer devices:

• Precise wavelength delivery for maximum cellular absorption
• Clinical-strength intensity unavailable in home devices
• FDA approval and medical-grade safety standards
• Published clinical evidence supporting efficacy

3 wavelengths target different skin concerns

Dermalux uses 3 specific wavelengths, each penetrating to a different depth and triggering distinct biological responses.

Red light (630–660nm) — collagen and elastin stimulation

Research published in the Journal of Investigative Dermatology↗ demonstrated that pulsed red LED light upregulates collagen synthesis while downregulating matrix metalloproteinase (MMP) expression.

• Stimulates collagen and elastin production
• Improves circulation and cellular metabolism
• Reduces fine lines and wrinkles
• Enhances skin texture and firmness

Blue light (415nm) — acne bacteria elimination

A randomised controlled trial published in the British Journal of Dermatology↗ found that blue light at 415nm achieved "a mean improvement of 76% in inflammatory lesions" when combined with red light, which was "significantly superior to that achieved by blue light alone, benzoyl peroxide, or white light."

• Targets and destroys P. acnes bacteria
• Reduces active breakouts
• Regulates sebum production
• Helps prevent future acne formation

Near-infrared (830nm) — deep tissue healing

A preliminary study in Laser Therapy↗ found that "830 nm LED-LLLT successfully brought about accelerated healing in wounds of different etiologies and at different stages, and successfully controlled secondary infection." Separate research on fibroblast cells↗ confirmed that 830nm irradiation stimulates nitric oxide production and inhibits pro-inflammatory cytokines.

• Penetrates deepest into tissue
• Reduces inflammation and pain
• Accelerates wound healing
• Enhances lymphatic drainage

Progressive results from session one

Immediate effects

Visible improvements appear from your very first session:

• Improved circulation creating a healthy glow
• Reduced inflammation for calmer, less reactive skin
• Enhanced hydration as cellular function improves
• Relaxation response from the soothing warmth

Progressive improvements over 4–8 weeks

Regular sessions produce cumulative changes that build on each other:

• Increased collagen production for firmer skin
• Reduced fine lines and improved texture
• Clearer complexion with fewer breakouts
• Even skin tone and enhanced radiance
• Accelerated healing of existing blemishes

Monthly maintenance sustains long-term results

LED therapy benefits are cumulative, meaning consistent sessions build on previous results. Without maintenance, improvements gradually fade over 2–3 months.

Monthly sessions sustain collagen production, maintain cellular health, and prevent skin regression. Seasonal intensives — a short course of 4–6 sessions — address changing skin needs during challenging months.

Suitable for all skin types and ages

LED therapy is one of the most broadly applicable treatments I offer. Unlike some laser treatments, it carries minimal risk of pigmentation changes, making it suitable across diverse skin types.

Skin types that respond well to LED

• All skin tones — safe with minimal risk of pigmentation changes, unlike some laser treatments
• All ages — from teenagers with acne to mature clients seeking anti-ageing support
• Sensitive skin — a gentler alternative for those who cannot tolerate chemical peels or more intensive treatments
• During pregnancy — generally considered a gentler option, though I recommend discussing any treatment with your healthcare provider first

Conditions LED therapy addresses

Acne and breakouts:

• Active acne treatment
• Prevention of future breakouts
• Healing of existing blemishes
• Reduced post-acne scarring

Anti-ageing concerns:

• Fine lines and wrinkles
• Loss of firmness
• Uneven texture
• Dull complexion

Skin healing:

• Post-treatment recovery
• Wound healing acceleration
• Rosacea and sensitivity
• General skin health maintenance

What to expect during a session

Consultation and preparation

Your first appointment includes a thorough skin analysis so I can recommend the right wavelength combination and session frequency. I'll create a personalised treatment schedule based on your specific concerns and set clear expectations from the start.

Treatment process takes 20 minutes

You'll lie comfortably while the Dermalux LED panel is positioned above your face. The treatment is completely pain-free — many clients describe a gentle, warming sensation that feels deeply relaxing. Each session lasts about 20 minutes, making it easy to fit into a busy schedule.

No downtime after treatment

You can return to normal activities immediately after LED therapy. Makeup can be applied straight away, and there are no restrictions on sun exposure or exercise.

Treatment protocols vary by skin concern

Acne treatment protocol:

• Initial phase: 2 sessions per week for 4 weeks (8 sessions)
• Maintenance: 1 session per week for 4 weeks
• Long-term: Monthly maintenance sessions

Anti-ageing protocol:

• Intensive phase: 1–2 sessions per week for 6–8 weeks
• Maintenance: Monthly sessions ongoing
• Seasonal boosts: Intensive courses 2–3 times yearly

Post-treatment healing protocol:

• Immediate: 1–2 sessions immediately after another treatment
• Recovery: Daily sessions for 3–5 days if needed
• Ongoing: As part of treatment aftercare

LED enhances other treatments

LED therapy accelerates healing and amplifies outcomes when paired with other treatments. I regularly combine it with:

Post-microneedling:

• Accelerates healing and reduces downtime
• Enhances collagen stimulation
• Minimises post-treatment inflammation

After chemical peels:

• Soothes treated skin
• Reduces recovery time
• Enhances overall results

Following facials:

• Extends and amplifies benefits
• Provides additional hydration boost
• Creates lasting glow

With mesotherapy:

• Supports healing at injection sites
• Enhances nutrient absorption
• Maximises treatment outcomes

• Active cancer in the treatment area
• Certain medications that cause photosensitivity
• Epilepsy that may be triggered by flashing lights
• Pregnancy (I recommend consulting your healthcare provider first)

Frequently asked questions

Is LED therapy actually backed by science, or is it just coloured lights?

LED therapy uses specific, clinically proven wavelengths that trigger measurable biological responses. Peer-reviewed research shows 140–200% increases in cell growth, and a randomised controlled trial found 76% improvement in inflammatory acne lesions. This is not ambient lighting — it is photobiomodulation with documented cellular effects.

Are home LED devices as effective as professional treatments?

Professional devices deliver significantly higher intensity and more precise wavelengths than home units. Clinical-strength output is the main reason results differ. Home devices can support maintenance between sessions, but they cannot replicate the power or precision of Dermalux. In my experience, clients who rely solely on home devices see slower, less consistent results.

What skin concerns can LED therapy treat?

3 different wavelengths address distinct concerns. Blue light (415nm) targets acne bacteria, red light (630–660nm) stimulates collagen for anti-ageing, and near-infrared (830nm) penetrates deepest for wound healing and inflammation. I select the wavelength combination based on your skin assessment.

How quickly will I see results from LED therapy?

Some benefits appear from session 1 — improved circulation, reduced redness, and a healthy glow. Optimal results develop progressively over 4–8 weeks of consistent treatment. As one client put it: "I was sceptical about LED therapy at first, but the results speak for themselves. My fine lines have softened, and my skin has a glow that people constantly comment on."

Is LED therapy safe during pregnancy?

LED therapy is generally considered a gentler option during pregnancy, as it is non-invasive, pain-free, and does not use UV light. However, I always recommend discussing any treatment with your healthcare provider first. During your consultation, I'll review your full medical history before recommending a protocol.
