When selecting a laser system for hair removal or dermatological treatments, it’s essential to understand the key distinctions among the most widely used technologies: Alexandrite lasers. All three laser types possesses unique properties that make one preferable for specific skin tones, various hair colors, and diverse treatment objectives.



Alexandrite lasers emit light at a 755 nm wavelength. The 755 nm output is highly efficient at absorbing melanin within the hair follicle, making this laser exceptionally effective for individuals with low to moderate melanin levels and dense dark hair. Treatment with Alexandrite provides quick treatment durations, which is why they are widely favored for extensive zones such as the lower limbs, torso, or shoulders. However, because Alexandrite lasers concentrate on melanin, лазерная эпиляция лица киев are contraindicated for skin with elevated melanin concentration, as they may cause thermal injury or permanent pigmentation changes.



This technology operate at a longer 1064-nanometer wavelength. The extended reach enables the energy to circumvent superficial pigmentation, allowing it to access follicles without overheating the skin. Consequently, Nd:YAG is the gold standard for individuals with Fitzpatrick types IV–VI. Additionally, address low-contrast follicles, though the results may be more modest compared to Alexandrite. Because the energy disperses further, each session may last longer, and multiple treatments are often needed to achieve long-term clearance.



Diode lasers typically emit light in the eight hundred to eight hundred ten nanometer range, bridging the gap between Alexandrite and Nd:YAG. They provide consistent performance across light to medium-dark complexions and excel at removing thick pigmented follicles. Known for their industrial-grade stability, diode systems are a top choice in aesthetic centers. Leading systems include built-in contact cooling that reduce pain, and their parameters can be customized precisely to suit personalized treatment profiles.



To determine the best fit, evaluate your complexion, hair color and texture, and the specific area being treated. When your skin is low melanin and high hair contrast, the Alexandrite laser often provides the fastest, most dramatic results. If your skin is darker, the Nd:YAG laser is recommended. When you want broad compatibility, the diode option delivers a dependable middle ground. Be sure to consult with a qualified aesthetic professional who can conduct a personalized assessment and tailor the best solution. The ultimate goal is not merely effectiveness—it’s ensuring safety and maintaining skin health.
