LED Light Therapy (Photobiomodulation)

Non-thermal LED light therapy delivering multiple wavelengths — red, blue, yellow, green and violet — to stimulate skin regeneration, reduce inflammation, accelerate wound healing after aesthetic procedures, tighten pores, stimulate hair growth on the scalp and regulate melanin production. At DermaMedEst LED therapy is used both as a standalone skin-health treatment and as a recovery modulator after laser or chemical peel sessions. Sessions are painless and require no recovery time.

LED photobiomodulation (PBM) uses specific wavelengths of non-coherent light to stimulate cellular processes in the skin without producing thermal damage. Unlike lasers that rely on heat for their clinical effect, LED devices work through photochemical reactions: photons at particular wavelengths are absorbed by chromophores in the mitochondrial respiratory chain — primarily cytochrome c oxidase — enhancing ATP synthesis, reducing oxidative stress and triggering downstream signalling cascades that regulate inflammation, proliferation and repair. At DermaMedEst the LED lamp emits multiple wavelengths selectable based on clinical indication. Red light (approximately 630–660 nm) penetrates to the dermis, stimulating fibroblast collagen and elastin synthesis and reducing inflammatory mediators; it is the primary wavelength for anti-aging and post-procedure recovery. Blue light (approximately 415 nm) has direct anti-bacterial action against Cutibacterium acnes by generating reactive oxygen species within the bacterial cell, making it the choice wavelength for active acne treatment without antibiotics. Yellow light (approximately 590 nm) targets superficial blood vessels and supports lymphatic circulation, reducing redness and improving skin uniformity. Green light (approximately 520 nm) targets melanin-producing cells, moderating melanin synthesis and supporting the management of pigmentation irregularities. Violet light (approximately 405–420 nm) has overlapping anti-bacterial properties with blue and is also used for scalp stimulation protocols. At DermaMedEst LED therapy serves several distinct clinical roles. As a standalone anti-aging protocol, a course of six to eight sessions spaced one to two weeks apart builds collagen stimulation and improves skin radiance. As a post-laser or post-peel adjunct — a particularly common use at this clinic — LED reduces the post-treatment inflammatory load, accelerates re-epithelialisation and shortens the period of redness after CO2 fractional resurfacing or chemical peeling. For scalp hair-loss protocols, the lamp is positioned over the scalp and violet or red wavelengths stimulate follicular blood supply and extend the anagen phase, complementing the mesotherapy and PRP injection programmes. Protective eye shields are always worn during the session. Treatment is entirely painless — patients lie comfortably under the lamp for 20–25 minutes. No preparation is required; there is no recovery period and patients can apply make-up immediately after.
