Diode vs Alexandrite vs Nd:YAG – Which machine is best? If you’re finally ready to ditch the razor and commit to laser hair removal, you’ve probably started Googling machines. And now… you’re confused. Diode? Alexandrite? Nd:YAG? What do these even mean? Which one is best? And does it actually matter or is this all just medical jargon? The answer is, yes, it matters. A lot. Each laser operates at a different wavelength. And that affects how deeply it penetrates the skin, how it targets hair, and how safe and effective it is based on your skin tone, hair type, and area of concern. So if you’re looking for a solution that’s quick, effective, and won’t leave you with burns or patchy results, choosing the right machine isn’t optional, it’s essential.
Diode vs Alexandrite vs Nd:YAG – which machine is best?
1. Alexandrite Laser (755 nm)
This is often hailed as the gold standard for lighter skin types with dark, coarse hair. It works fast, has a high melanin absorption rate, and is ideal for large areas like legs, backs, chests, or arms. But here’s the catch. It’s not suitable for darker skin tones. Why? Because it can overheat the skin’s pigment, leading to burns or hyperpigmentation.
2. Diode Laser (810 nm)
Diode lasers are a versatile choice. They go deeper than Alexandrite, which means they’re safer on medium to olive skin tones. They’re efficient, especially for thicker hair and smaller areas like the face or shoulders.
That said, not all Diode lasers are created equal. Some machines (especially older ones or budget models) lack the cooling systems or pulse control needed to treat sensitively and safely. Although patients report Diode being less painful, at the same time patients who have had both Diode and Alexandrite – 99% of patients would choose Alexandrite over Diode for its power and results.
3. Nd:YAG Laser (1064 nm)
The deepest penetration and the safest option for darker skin tones. Nd:YAG lasers bypass the pigment in the skin and target only the follicle, reducing risk of surface damage. They’re also fantastic for treating conditions like folliculitis, ingrown hairs, and even keratosis pilaris.
So, which machine is better?
There isn’t a one-size-fits-all answer, because your skin and hair combination is unique.
The best machine for you is the one that suits:
- Your skin tone
- Your hair density and colour
- The area you want treated
- And your long-term skin health and safety
