The 1064nm Nd: YAG laser has proved to be one of the most useful light sources for the treatment of deep vascular lesions and spider veins. A deeper penetration and a lower absorption by haemoglobin make this wavelength highly effective for thick vascular lesions, more so traditionally used shorter wavelengths (KTP, pulsed dye, IPL, diode). Adequate absorption of this wavelength is achieved by haemoglobin, a system able to control the depth of penetration through appropriate spot selection. With variable pulse duration to adjust to different vessel diameters, high fluences, and optimal cooling systems to avoid pain or burning, Nd YAG lasers can theoretically treat any vascular lesion, superficial, deep or thick. Additionally, variable spot sizes, highly-variable pulse duration and high fluences (CoolGlide Vantage, Cutera) have been evaluated for the treatment of a wide spectrum of vascular lesions. Results are especially noticeable on rosacea, leg veins, facial spider veins, cherry angioma (ruby point), and thick hemangiomas venus lake. Moderate pain was reported on deeper or thicker lesions, but was decreased with longer or additional cooling with ice packs.
The human skin produces about one million skin cells every 40 minutes, which equates to over 36 million skin cells per day. As our skin cells renew from the deeper layer of the epidermis, the more surface cells harden and lose moisture. Eventually these cells detach from skin and are replaced by younger cells moving up from deeper layers. Desquamation (detaching) also eliminates damaged and contaminated cells that carry pollutants and micro-organisms from the environment. These superficial skin cells don’t always effectively fall from skin and may cause clogging and congestion while leaving and the skin’s surface dry and dull looking. As we age, desquamation and cell turnover slow down, from approximately 20 days in younger and middle-aged adults up to over 30 days in older adults; making professional peeling and exfoliation critical to removing the accumulation of cells that give a dry, dull, hyperpigmented appearance to the skin. Chemical peels are one of the most effective ways to address these changes. But they’re not a one-size-fits-all treatment: for optimal results, a peel should be strong enough to accelerate cell turnover but not so powerful as to induce severe skin inflammation. Through professional peels, these dulling skin cells effectively removed, and newer cells are revealed for fresher, healthier appearance.
