Vascular Laser — QuadroStar (Rosacea & Spider Veins)

CLED uses the QuadroStar high-power vascular laser — the clinic's first-choice device for rosacea, facial spider veins (telangiectasias) and angiomas. The QuadroStar targets oxyhaemoglobin in dilated vessels with its 532 nm KTP and 1064 nm Nd:YAG dual-wavelength capability, selectively heating and collapsing abnormal vessels while the passive cooling system protects surrounding tissue. MUDr. Moskalyková has used the QuadroStar for vascular treatment since CLED's founding and applies it to red and reddish-purple lesions across the face, neck and décolletage.

Vascular laser treatment is built on selective photothermolysis directed at haemoglobin: the laser emits at a wavelength strongly absorbed by oxyhaemoglobin in the blood inside dilated vessels, converting light energy to heat within the vessel wall until it coagulates and collapses. The coagulated vessel is then cleared by the body's phagocytic processes over the following two to six weeks, progressively disappearing from view without leaving scar tissue. The QuadroStar at CLED is a dual-capability vascular laser system operating at both 532 nm (KTP frequency-doubled Nd:YAG) and 1064 nm (Nd:YAG). The 532 nm wavelength has a very high absorption coefficient for oxyhaemoglobin and is highly effective against superficial red capillaries — the fine thread-like telangiectasias on cheeks and nose characteristic of early rosacea and sun-related vessel damage. The 1064 nm wavelength penetrates more deeply and carries lower melanin absorption, making it the better choice for deeper or larger vessels, reddish-purple lesions and patients with tanned or darker skin types where the shorter wavelength risks epidermal pigmentation changes. The QuadroStar also incorporates a passive cooling system that chills the skin surface during and between pulses to protect the epidermis. Rosacea is perhaps the most frequent indication at CLED. The condition produces chronic diffuse facial redness through a combination of permanently dilated superficial capillaries and a dysregulated vascular inflammatory response. QuadroStar sessions shrink and eliminate the visible telangiectasias that contribute to the background redness and reduce the frequency of flushing episodes. A full course of two to four sessions is typically recommended for established rosacea; single sessions are often sufficient for isolated spider veins or small angiomas. MUDr. Moskalyková applies the laser pulses directly over the visible vessels, working systematically across the treatment zone. Immediately after treatment the target vessel may transiently appear darker (purpura) as the coagulated blood within it absorbs into the vessel wall; this resolves over one to two weeks. Post-treatment redness is expected for a few hours. Sun avoidance and SPF 50+ use during the healing period are essential to prevent hyperpigmentation. Contraindications include recent intense sun exposure, isotretinoin use, and active skin infection in the treatment zone.
