Clinical light therapy for calmer, clearer, more radiant skin — zero downtime.
Advanced Aesthetic Treatment
Advanced Skin Healing and Rejuvenation with Dermalux Flex™ LED
LED Phototherapy is a non-invasive treatment that uses clinically proven wavelengths of light to stimulate natural skin processes and restore optimal skin function. Each wavelength targets specific concerns within the skin, delivering energy at precise depths without heat or damage.
What Is LED Phototherapy?
Your cells already know how to heal. LED gives them the energy to do it faster.
At Cosmo Medispa, we use the Dermalux Flex™ — a professional-grade LED device that delivers three precisely calibrated wavelengths simultaneously: 633nm red, 830nm near-infrared, and 415nm blue. Each wavelength penetrates to a different depth and triggers a distinct biological response — from collagen stimulation in the dermis to bacterial elimination at the follicle, to deep-tissue inflammation control.
How It Works
Three wavelengths. Three depths. One coordinated cellular response.
The Dermalux Flex™ delivers three clinically validated wavelengths simultaneously — each absorbed by specific chromophores in the skin at different depths, triggering distinct but complementary biological processes. The combined effect is a multi-layered cellular response that addresses ageing, inflammation, acne, and healing in a single comfortable session.
What It Treats
Conditions treated by Dermalux Flex™
633nm Red Light — Collagen Synthesis & Anti-Ageing
Red light at 633nm penetrates the dermis and is absorbed by fibroblast mitochondria, stimulating ATP production and accelerating the synthesis of Type I and Type III collagen and elastin. The result is progressive firming, reduced fine lines, and improved skin density. Red light also suppresses inflammatory markers, making it highly effective for sensitive, reactive, and rosacea-affected skin.
830nm Near-Infrared — Deep Tissue Recovery
Near-infrared at 830nm penetrates deepest — reaching subcutaneous tissue and muscle. It stimulates mitochondrial activity in deeper layers, accelerates cellular repair, improves tissue oxygenation, and is the most potent wavelength for reducing post-procedure inflammation. This makes it the primary wavelength used after HIFU, RF Microneedling, or chemical peels to accelerate recovery and enhance collagen results.
415nm Blue Light — Acne Bacteria Elimination
Blue light at 415nm targets and destroys Cutibacterium acnes — the bacteria responsible for inflammatory acne — through photoactivation of endogenous porphyrins. The bacteria absorb the blue light and produce reactive oxygen species that destroy the bacterial cell from within. This mechanism reduces active breakouts without antibiotics, without irritation, and without the risk of bacterial resistance.
Tri-Wave Therapy — Customised Multi-Wavelength Combinations
For enhanced and accelerated results, Dermalux therapy can deliver multiple wavelengths simultaneously — combining Blue, Red and Near Infrared light in a single session. This multi-wavelength Tri-Wave approach treats a multitude of skin needs at once, fully customisable to your unique skin qualities and concerns, producing a more comprehensive biological response than any single wavelength alone.
Dermalux Flex™ — Clinical-Grade Irradiance
The Dermalux Flex™ delivers precise irradiance output at each wavelength — ensuring the light energy reaching the skin sits within the clinically validated therapeutic window. Consumer LED devices deliver irradiance levels typically 10–50 times lower and lack simultaneous multi-wavelength delivery. The Dermalux Flex™ is a clinical treatment device, calibrated to produce the biological response proven in clinical literature.
The Benefits
Real outcomes. Lasting change.
Every benefit below is achieved without surgery, general anaesthesia, or recovery time — just advanced technology and expert hands.
Reduced Fine Lines & Improved Firmness
Red and near-infrared wavelengths stimulate fibroblast collagen production in the dermis — progressively increasing skin density, reducing the depth of fine lines, and improving overall firmness and elasticity. Results build cumulatively across the course, with continued improvement between sessions as the collagen synthesis response continues beneath the surface.
Cleared Active Acne
Blue light at 415nm destroys acne-causing bacteria at the follicle through porphyrin photoactivation — reducing the bacterial load responsible for inflammatory breakouts without antibiotics, drying agents, or skin irritation. Combined with red light's anti-inflammatory action, LED provides comprehensive management of both the bacterial cause and the inflammatory response that drives persistent acne.
Reduced Redness & Rosacea Symptoms
LED Phototherapy's anti-inflammatory action — particularly via red and near-infrared light — suppresses the pro-inflammatory cytokines responsible for chronic redness, flushing, and reactive skin. It is one of the few treatments actively suitable for rosacea and hypersensitive skin, producing a calming, barrier-strengthening effect without triggering any reaction.
Accelerated Post-Treatment Recovery
Near-infrared light dramatically accelerates cellular repair and reduces post-procedure inflammation after HIFU, RF Microneedling, skin needling, or chemical peels. Our dermal therapists integrates LED sessions immediately post-treatment — reducing recovery time, minimising redness, and amplifying the collagen-stimulating results of the primary procedure. One of the most evidence-backed combination strategies in clinical aesthetics.
Enhanced Skin Luminosity
Improved cellular energy levels, stimulated circulation, and accelerated cell turnover produce an immediate and progressive improvement in skin radiance — a brighter, more even, and more luminous complexion reflecting optimal skin health. This luminosity effect is one of the most immediately noticed and universally appreciated results of LED Phototherapy, visible from the very first session.
Zero Risk, Zero Downtime
LED Phototherapy produces no thermal damage, no mechanical trauma, and no chemical reaction in the skin. There is no redness, no peeling, no sensitivity, and absolutely no recovery time. You can resume all normal activities — including wearing full makeup — immediately after your session. This makes it suitable for every skin type, including the most sensitive, reactive, or compromised skin conditions.
Suitability

Questions
LED Phototherapy is one of the most comfortable treatments available. You lie beneath the Dermalux Flex™ panel for 30 minutes while the lights are active — you may notice a very gentle warmth, though many clients feel nothing at all. There is no discomfort, no tingling, and no heat sensation. The session is deeply relaxing — many clients describe it as the most enjoyable part of a treatment day, and some fall asleep.
The recommended course is 3–6 LED treatments spaced 1–2 times per week for optimal skin healing, inflammation reduction and collagen support. LED therapy can also be used regularly as a maintenance treatment to enhance overall skin health and accelerate recovery from advanced skin procedures. As a post-treatment recovery enhancer, a single LED session immediately after a primary procedure can be sufficient. Our dermal therapists will recommend the right course length and frequency during your consultation based on your specific skin concerns and treatment history.
Yes. LED Phototherapy is one of the very few aesthetic treatments that is genuinely safe for every Fitzpatrick skin type — including very fair, sensitive, rosacea-affected, and darker skin tones (I–VI). There is no risk of thermal damage, no risk of post-inflammatory hyperpigmentation, and no chemical reactivity. The only contraindications are photosensitive conditions or medications that increase light sensitivity — our dermal therapists will screen for these during your consultation before any treatment proceeds.
Yes — and we actively recommend it for most procedures. LED Phototherapy performs exceptionally well as an immediate post-treatment step after HIFU, RF Microneedling, skin needling, chemical peels, or microdermabrasion. Near-infrared light reduces post-procedure inflammation and accelerates tissue repair, while red light amplifies the collagen stimulation triggered by the primary treatment. This combination can meaningfully reduce downtime and enhance the overall result of the session.
The fundamental difference is irradiance — the intensity of light energy delivered to the skin. Clinical devices like the Dermalux Flex™ deliver irradiance levels within the validated therapeutic window that produces measurable photobiomodulation. Consumer LED masks typically deliver irradiance levels 10–50 times lower, which may produce mild surface benefits but cannot replicate the collagen synthesis, acne elimination, or recovery acceleration achievable with a clinical device. The Dermalux Flex™ also delivers three simultaneous wavelengths at calibrated therapeutic outputs — a multi-layered approach not available in any consumer product.
LED blue light reduces the population of acne-causing bacteria and suppresses the inflammatory response that drives breakouts — producing meaningful, lasting improvement across a treatment course. Results are typically maintained with periodic top-up sessions and a consistent, barrier-supporting skincare routine. For comprehensive long-term acne management, our dermal therapists often combines LED with O Cosmedics® chemical peels, active skincare, and targeted dietary recommendations as part of a structured acne programme. She will design the right long-term strategy for your skin at your consultation.
Absolutely — LED is one of the most versatile combination partners in our clinic. It integrates effectively with virtually every treatment we offer: post-HIFU to reduce inflammation and enhance lifting results, post-RF Microneedling or skin needling to amplify collagen response, post-chemical peel to accelerate barrier recovery, and post-microdermabrasion to calm and support the skin. It also works as a standalone skin maintenance treatment between more intensive procedures. Our dermal therapists will recommend the optimal integration of LED into your overall treatment programme.
Calm, clear, and visibly renewed — with zero days of downtime.
