Here’s a common question: “Alexandrite laser vs. Diode Laser – which one is better?” Well… it depends!
You live in the UAE and you know that the sun never sleeps. People here have very high beauty standards because we, more often than not, expose our skin to summer clothes. The best thing about Dubai (and the UAE) is that laser hair removal is one of the most effective ways to achieve smooth, hair-free skin.
Among the most popular laser technologies are Alexandrite and Diode lasers. Both offer unique benefits, but which one is right for you? This article helps you make an informed decision by explaining the different lasers’ similarities, differences, suitability, pricing, and scientific insights.

Alexandrite laser vs. Diode lasers: Similarities
As with everything – laser technologies share something in common. When it comes to laser hair removal, both lasers are similar in:
- Purpose: Both target the melanin in hair follicles, effectively reducing or permanently eliminating hair growth over time after several sessions.
- Mechanism: Use selective photothermolysis to destroy hair follicles while keeping surrounding skin tissue intact.
- Number of sessions: Both require multiple sessions to achieve optimal results, depending on hair type, treatment area, and skin tone.
- Time in between sessions: They both require between 4 and 6 weeks to ensure a new growth phase has started.
- Safety: Both lasers are FDA-approved in the US and safe when used by qualified professionals. This sets the standard worldwide.
- Permanent results: Both provide long-term hair reduction, with proper maintenance required occasionally.
Alexandrite laser vs. Diode lasers: Differences
| Feature | Alexandrite Laser | Diode Laser |
|---|---|---|
| Wavelength | 755 nm (shorter wavelength, ideal for melanin absorption) | 800–810 nm (longer wavelength, penetrates slightly deeper) |
| Skin Types Treated | Best for lighter skin tones (Fitzpatrick I-III) | Suitable for a wider range of skin tones (I-VI) |
| Sessions Required | Fewer sessions due to higher melanin absorption (6-8) | May require more sessions for comparable results (8-10) |
| Comfort | Advanced cooling airflow for skin protection and comfort | Uses cooling gel, which can feel sticky and less hygienic |
| Hygiene | No skin contact. The airflow prevents heat buildup and ensures hygiene | Requires direct skin contact with cooling gel, raising hygiene concerns |
| Speed | Covers larger areas quickly due to faster energy delivery | Slower process due to smaller spot size |
| Hair Type | Highly effective on fine to medium hair | More effective for dense, thick hair but less so for finer hair |
Here’s the Fitz Patrick scale for your reference:
Why Alexandrite laser stands out
You may have noticed that the Alexandrite laser has more benefits than the Diode one. That’s because of the technology advancement. Here’s where Alexandrite wins the most:
- Cooling system: Alexandrite lasers incorporate advanced cooling airflow technology, which delivers heat to the skin without the need for direct contact. This increases treatment speed and hygiene.
- Efficiency: With its shorter wavelength, the Alexandrite laser is highly efficient at targeting melanin in hair follicles. That results in faster and fewer sessions for optimal results.
- Hygiene: Unlike Diode lasers, Alexandrite doesn’t require a gel applicator, ensuring a cleaner and more sanitary experience for you.
Alexandrite laser vs. Diode lasers: How do you pick the right one?
Picking the right laser is essential for your hair removal experience. The general rule is to avoid picking a clinic based on its treatment cost. Always determine your choice by the following criteria: skin type, hair type, treatment area, and hygiene standards.
Alexandrite Laser:
- Best for individuals with fair to light skin tones (Fitzpatrick I-III) and dark, fine-to-medium hair.
- Ideal for treating larger areas like legs, arms, and back due to its speed and precision.
Diode Laser:
- Suitable for a wider range of skin tones, including darker complexions (Fitzpatrick IV-VI).
- Better for smaller areas like the bikini line or face and for dense, thick hair types.
How to Choose:
The best way to choose the right laser for your skin is to consult a professional. Each clinic can help you analyze your skin tone, hair type, and treatment goals. At 7 Derma, we provide personalized consultations to recommend the best laser for you.
Price range in the UAE
All lasers can treat multiple areas. For the article, we’ll look into the prices for one session full-body treatments.
The prices depend on the clinic’s reputation, laser type, and location.
- Alexandrite Laser: AED 500–1,500 per session.
- Diode Laser: AED 300–1,200 per session.
Keep in mind that these prices are relevant for December 2024. They may change (usually increase) based on inflation, and user demands.
Reasons for price differences
The core difference between both lasers is in the technology type, the treatment speed, hygiene standards, and expertise. That’s why it’s very important to ask the clinic you’ve picked “What type of laser do you use – alexandrite or diode?”
At 7 Derma, we use Alexandrite laser because it has proven it’s benefits for our clients – less sessions, faster treatments, better hygiene:
- Technology and maintenance: Alexandrite lasers are more expensive to maintain and operate due to their advanced systems and higher energy output.
- Treatment speed: Alexandrite lasers’ ability to treat larger areas faster can reduce overall session costs in the long run.
- Hygiene standards: Alexandrite’s no-contact treatment minimizes the need for disposable supplies like gel, maintaining higher cleanliness standards.
- Expertise: Clinics offering Alexandrite laser treatments often invest in highly trained professionals, contributing to higher session costs.
Scientific research on effectiveness
Numerous studies highlight the effectiveness of both lasers:
Comparison of Long-Pulsed Diode and Long-Pulsed Alexandrite Lasers for Hair Removal
This study involved 20 women with Fitzpatrick skin types I–IV and dark terminal hair. Participants underwent three monthly laser-assisted hair removal sessions with both laser types. The results indicated that both lasers are effective, with specific advantages depending on hair and skin type.
Laser Hair Removal: Comparison of Long-Pulsed Alexandrite and Long-Pulsed Diode Lasers
This case study analyzed 805 laser-assisted hair removal treatments on 75 patients. The mean hair reduction was 65.6% for Alexandrite lasers and 46.9% for Diode lasers, highlighting the higher efficacy of Alexandrite lasers in certain cases.
Comparison of Long-Pulsed Alexandrite and Nd:YAG Lasers, Individually and in Combination, in Long-Term Hair Reduction
This clinical trial compared the long-term effectiveness and safety of Alexandrite and Nd:YAG lasers. The study found that Alexandrite lasers are highly effective for long-term hair reduction, particularly in individuals with lighter skin tones.
Comparison studies:
- Alexandrite lasers are generally more effective for clients with lighter skin and finer hair.
- Diode lasers excel in treating darker skin tones and thicker hair but often require more sessions for equivalent results.
Conclusion: Expert Guidance for Your Laser Journey
At 7 Derma we recommend Alexandrite laser for clients seeking faster, more hygienic, and effective treatments, especially for lighter skin tones and finer hair. If you have darker skin or coarser hair, a consultation will help determine the best course of action.
