The light/laser technology uses targeted light pulses to heat and selectively obliterate the affected blood vessels in the skin without damaging the surrounding tissue. This leads to a reduction in redness and an improvement in the appearance of the skin. Laser treatments offer very precise pulses of light, but also a broad spectrum of light wavelengths which makes them suitable for treating a variety of skin tones and types as well as different types of skin redness, including rosacea, couperose and sun damage.
