Alma Harmony Dye-VL — Pigmentation & Vascular Treatment

The Alma Harmony Dye-VL module delivers intense pulsed light in wavelength bands optimised for two distinct chromophores: haemoglobin in the oxygenated blood of dilated superficial vessels, and melanin in epidermal pigment deposits such as solar lentigines and post-inflammatory hyperpigmentation. By filtering the broadband light output to these specific spectral windows, the Dye-VL achieves selective photothermolysis of vascular and pigmented targets…

For vascular lesions — rosacea-related diffuse redness, spider veins (telangiectasias), couperose and facial flushing — the absorbed light energy heats the blood within the vessel, causing coagulation of the endothelium and subsequent vessel collapse. The coagulated vessel is cleared by the body's macrophage system over two to four weeks, after which the previously visible redness or thread-like capillary disappears. For rosacea patients the reduction in…

For pigmentation — sun spots, age spots, mild melasma and uneven skin tone — the absorbed energy fragmentises melanin granules, which are then cleared through the stratum corneum (they briefly appear darker before lifting off as very fine flaking) and via macrophage clearance in the dermis. The photothermal effect also provides mild collagen stimulation, contributing to overall skin tone improvement.
