LED light therapy uses specific wavelengths of visible and near-infrared light to stimulate cellular repair, reduce inflammation, and improve skin health — with no heat, no discomfort, no downtime, and no risk of post-inflammatory pigmentation. It is the safest treatment we offer, and one of the most versatile.

How Does LED Therapy Work?

Photobiomodulation — the clinical term for LED light therapy — works by delivering specific wavelengths of light energy to skin cells, where they are absorbed by photoreceptors within the mitochondria (the cellular energy centres). This absorption triggers a cascade of biological responses: increased ATP (energy) production, stimulation of collagen and elastin synthesis, modulation of inflammatory cytokines, and activation of the skin’s natural repair processes.

Different wavelengths of light penetrate to different depths within the skin and produce different biological effects. At PHP Aesthetic-Wellness, treatment panels combine multiple wavelengths in a single session, targeting the concern at the appropriate tissue depth.

“LED therapy is the treatment we recommend most often as either a foundation or a complement to other protocols. It calms what needs to be calmed, repairs what needs to be repaired, and it can be used on even the most reactive skin on even the most inflamed day. That versatility is unique.”PHP Aesthetic-Wellness, 22 Harley Street

The Wavelengths We Use

Blue Light — 415nm

Destroys Propionibacterium acnes (the bacteria responsible for acne) at the skin surface by activating naturally occurring porphyrins within the bacteria. The primary wavelength for active inflammatory acne.

Red Light — 633nm

Penetrates to the dermis to stimulate fibroblasts, collagen production, and tissue repair. Reduces inflammation and accelerates healing. The most widely used wavelength in aesthetic LED therapy, effective for anti-ageing, rosacea, and post-procedure recovery.

Near-Infrared — 830nm

Penetrates deepest into the tissue — reaching the hypodermis and supporting structures. Powerful anti-inflammatory and immunomodulatory effects; promotes cellular regeneration and reduces the chronic low-grade inflammation driving conditions such as rosacea and eczema.

Yellow Light — 590nm

Targets superficial blood vessels and redness, making it particularly useful for vascular conditions, flushing, and the erythema of early rosacea. Also improves lymphatic drainage and skin oxygenation.

What LED Therapy Treats

✨

Acne & Blemishes

Blue light destroys acne bacteria; red and near-infrared light reduce the associated inflammation and support healing. LED is the first-line in-clinic treatment for active inflammatory acne and can be used safely during flares.

Rosacea & Redness

Red, yellow, and near-infrared wavelengths calm the chronic vascular and immune reactivity of rosacea, reduce flushing, and progressively improve the skin’s tolerance to everyday triggers. Safe during active rosacea episodes.

Anti-Ageing & Collagen

Red and near-infrared light stimulate fibroblasts to produce new collagen and elastin, improving skin firmness, reducing fine lines, and restoring a more youthful skin quality over a course of treatment.

Post-Procedure Recovery

LED therapy applied following microneedling, chemical peels, or other procedures significantly accelerates healing, reduces redness, and amplifies the regenerative response. The most common combination at PHP Aesthetic-Wellness.

Safe for all skin tones. LED therapy carries no risk of post-inflammatory pigmentation and is fully appropriate for Fitzpatrick types I–VI. It is one of the very few aesthetic treatments that can be used on actively inflamed, reactive, or sensitive skin without risk of worsening the condition.

Frequently Asked Questions

Does LED therapy hurt?
No. LED therapy is completely painless. Patients feel a gentle warmth from the panel and often find the sessions relaxing. There is no heat intense enough to cause discomfort, and no needles, lasers, or physical contact with the skin.
How many sessions do I need?
For acne and rosacea, a typical initial course is six to ten sessions at weekly intervals. For anti-ageing and collagen stimulation, eight to twelve sessions produce the most consistent results. LED is also used as a single post-procedure session following microneedling or peels. Maintenance sessions monthly or quarterly are recommended for ongoing benefit.
Can LED be combined with other treatments?
Yes — and it frequently is. LED therapy enhances the results of microneedling, chemical peels, and exosome treatment when applied immediately afterwards. It is also used alongside prescription topicals for acne and rosacea to produce a faster and more sustained clinical response than either approach alone.
Is LED therapy effective for darker skin tones?
Yes, completely. LED therapy has no adverse effect on melanin and is as effective across all Fitzpatrick skin types. For patients with darker skin tones in particular, it is valuable as a treatment for acne, post-inflammatory hyperpigmentation, and rosacea precisely because it addresses those concerns without any risk of the pigmentary side effects associated with other modalities.
Are there any contraindications?
LED therapy is contraindicated for patients taking photosensitising medications (including certain antibiotics and retinoids), those with active epilepsy where flickering light is a trigger, and during pregnancy. Patients with certain eye conditions should ensure appropriate eye protection is worn. A brief medical history is taken before every session at PHP Aesthetic-Wellness.
