Alexandrite vs Nd:YAG: Which Laser Hair Removal Technology Is Best for Your Skin Type?
Jan 13, 2025


Unwanted hair can affect confidence and comfort, which is why many people turn to laser hair removal for a long-term solution. But not all lasers are the same, and choosing the right one depends on your skin type. At Écou’s Laser Boutique in Scottsdale, we use the most advanced dual-wavelength technology to safely and effectively treat every skin tone.
Here’s a breakdown of how laser hair removal works, the Fitzpatrick skin type scale, and which laser is best suited for your unique needs.
How Laser Hair Removal Works
Laser hair removal is based on selective photothermolysis. The laser emits a light beam that targets melanin (pigment) in the hair. Melanin absorbs the light, converts it into heat, and damages the follicle, which slows or stops future hair growth.
Because darker hair contains more melanin, it responds best, but modern technology has made treatments effective and safe across a wide range of skin tones and hair types.

Fitzpatrick Skin Type Scale
The Fitzpatrick scale helps determine your skin tone and response to light:
Type I: Pale white skin, always burns, never tans
Type II: Fair skin, burns easily, tans poorly
Type III: Light/medium skin, sometimes burns, tans gradually
Type IV: Light brown skin, rarely burns, tans easily
Type V: Brown skin, rarely burns, tans darkly
Type VI: Dark brown/black skin, never burns, always tans deeply
Alexandrite Laser (755 nm) – Best for Skin Types I–III
The Alexandrite laser uses a 755 nm wavelength, which has high melanin absorption, making it ideal for lighter skin tones.
Benefits:
Highly effective for light to medium skin with darker hair
Faster sessions due to a larger spot size
Excellent results with fewer treatments
At Écou’s Laser, our Lutronic Clarity II Alexandrite laser delivers precise, powerful treatments with built-in cooling for safety and comfort.
Nd:YAG Laser (1064 nm) – Best for Skin Types IV–VI
The Nd:YAG laser operates at a 1064 nm wavelength, which penetrates deeper and avoids excessive melanin absorption in the skin. This makes it the safest option for darker skin tones.
Benefits:
Safely treats skin types IV–VI
Lower risk of burns or pigmentation changes
Works best on coarse, dark hair
Often considered less painful due to longer wavelength
At Écou’s, we use the advanced Clarity II Nd:YAG platform, ensuring effective treatments tailored to darker skin types without compromising safety.
Why Dual-Wavelength Technology Matters
At Écou’s Laser Boutique in Scottsdale, we’re proud to offer FDA-approved dual-wavelength technology (755 nm Alexandrite + 1064 nm Nd:YAG) in a single platform. This means:
Every skin type can be treated safely
Custom settings for hair color, thickness, and area of the body
A personalized approach for maximum results with minimal risk
Final Thoughts
Choosing the right laser is critical for safe and effective hair removal. Alexandrite lasers excel for lighter skin tones, while Nd:YAG is best for darker skin tones. With our Clarity II dual-wavelength system, you don’t have to worry—we customize every treatment for your unique needs.
