IPL vs Diode vs Alexandrite Lasers—Which Works Best for SG Skin?
Introduction
When it comes to long-term hair removal or skin rejuvenation in Singapore, the options can be overwhelming. The market is filled with terms like IPL, Diode Laser, and Alexandrite Laser, each claiming to be the “best” solution for smooth, hair-free skin.
But here’s the truth — while all three use light energy to target unwanted hair and improve skin texture, they differ significantly in technology, effectiveness, safety, and suitability for Asian skin.
With Singapore’s tropical weather, sun exposure, and diverse range of skin tones (especially Fitzpatrick types III–V common among Asians), choosing the right laser or IPL treatment can make the difference between achieving lasting results — or experiencing irritation and wasted sessions.
This detailed 2025 guide breaks down the differences between IPL, Diode, and Alexandrite Lasers, explaining how they work, their pros and cons, and which one truly suits Singaporean skin types best.
By the end of this article, you’ll know exactly what to expect from each technology, the results timeline, and why Dr Plus Clinic Singapore is a trusted choice for personalised, medically supervised treatments.
Understanding Light-Based Hair Removal
Before comparing IPL and lasers, it’s important to understand one key point:
IPL (Intense Pulsed Light) is not a laser.
While both use light energy to destroy hair follicles or improve pigmentation, IPL emits multiple wavelengths of light, whereas lasers use a single, concentrated wavelength for precision.
This difference is what gives each technology its unique advantages and limitations — especially for different skin tones and hair types.
How Light-Based Hair Removal Works
The Basic Principle: Selective Photothermolysis
All laser and IPL hair removal systems work on the concept of selective photothermolysis, which means targeting a specific pigment (melanin) in the hair follicle while sparing surrounding skin.
The light energy is absorbed by melanin, converted into heat, and destroys the follicle’s growth centre, preventing future regrowth.
However, because melanin also exists in skin pigment, there’s a fine balance — if the wavelength isn’t suitable, it can cause burns or post-inflammatory pigmentation (PIH), especially in Asian skin tones.
That’s why choosing the right wavelength for your skin type is critical.
IPL (Intense Pulsed Light)
What It Is
IPL stands for Intense Pulsed Light, a technology that uses broad-spectrum light ranging from 500–1200 nm. It’s not a laser, but a powerful flashlamp that emits multiple wavelengths to target both hair and pigmentation.
How It Works
The light penetrates the skin and gets absorbed by melanin in the hair shaft, heating and damaging the follicle to reduce future growth.
Because the wavelengths are broad, IPL can also treat pigmentation, redness, and dullness — making it a multi-purpose option.
Best For
- Light to medium skin tones (Fitzpatrick I–III)
- Fine to medium hair
- Pigmentation, freckles, redness, and uneven skin tone
Benefits
- Covers larger areas quickly (ideal for legs and arms)
- Cost-effective
- Can improve both hair and pigmentation issues
Limitations
- Less precise compared to lasers
- May not be ideal for darker skin tones
- Requires more sessions for lasting results
- Risk of burns or pigmentation if settings are not adjusted properly
Typical Results
You’ll notice gradual hair reduction over 6–10 sessions, but maintenance sessions are usually needed every few months.
Downtime
Minimal — mild redness or warmth for a few hours.
Average Cost (Singapore 2025)
$80 – $300 per session, depending on the body area and intensity.
Diode Laser
What It Is
The Diode Laser emits a single, specific wavelength of 810 nm, making it one of the most popular and safest technologies for Asian skin.
This wavelength penetrates deep into the hair follicle while minimising melanin absorption in the epidermis — ideal for darker skin tones.
How It Works
The laser light selectively targets the hair bulb’s melanin, heating it enough to disable the follicle without damaging surrounding skin. Integrated cooling systems make the process comfortable and safe.
Best For
- Medium to dark skin tones (Fitzpatrick III–V)
- Coarse or thick hair (legs, underarms, bikini line)
- Both men and women
Benefits
- Safe and effective for Asian skin tones
- Deeper penetration for coarse hair
- Less risk of burns or pigmentation
- Requires fewer sessions than IPL
Limitations
- Slightly more expensive than IPL
- Less effective for very fine or light-coloured hair
Typical Results
Visible hair reduction after 2–3 sessions, with 70–90% reduction after 6–8 sessions.
Downtime
None — only mild redness that resolves within hours.
Average Cost (Singapore 2025)
$100 – $500 per session, depending on area and number of pulses.
Why It’s Ideal for Singapore
Because Singapore’s population has predominantly medium to tan skin, the Diode Laser’s 810 nm wavelength provides the perfect balance between efficacy and safety — making it the go-to choice for permanent hair reduction in 2025.
Alexandrite Laser
What It Is
The Alexandrite Laser uses a wavelength of 755 nm, which is absorbed more strongly by melanin. This makes it extremely effective for fine and light hair, but riskier for darker skin tones.
How It Works
The shorter wavelength targets melanin near the surface, heating and destroying follicles quickly. However, because it interacts more with skin pigment, it’s typically best for lighter complexions.
Best For
- Fair to medium skin tones (Fitzpatrick I–III)
- Fine or light-coloured hair
- Large areas like legs and arms
Benefits
- Fast and powerful — treats large areas quickly
- Excellent for fine hair
- Produces visible results in fewer sessions
Limitations
- Not ideal for darker or tanned skin (risk of pigmentation)
- May cause burns if used incorrectly
- More painful than Diode or IPL if no cooling device is used
Typical Results
Hair growth reduces significantly after 4–6 sessions, with smoother texture and lighter regrowth.
Downtime
1–2 days of mild redness or warmth.
Average Cost (Singapore 2025)
$120 – $600 per session, depending on area size.
Why It’s Popular in 2025
With improved cooling systems and dual-wavelength machines, Alexandrite lasers have become safer for lighter Asian skin, though still less preferred for darker tones compared to Diode.
Comparing IPL vs Diode vs Alexandrite
| Feature | IPL | Diode Laser | Alexandrite Laser |
|---|---|---|---|
| Technology Type | Broad-spectrum light | Single 810 nm wavelength | Single 755 nm wavelength |
| Precision | Moderate | High | Very High |
| Skin Type Suitability | Light to medium | Medium to dark | Fair to light |
| Hair Type | Fine to medium | Coarse to medium | Fine to light |
| Effectiveness | Moderate | Excellent | Excellent (on fair skin) |
| Pain Level | Mild | Mild–Moderate | Moderate |
| Sessions Needed | 8–10 | 6–8 | 6–8 |
| Maintenance Needed | Frequent | Minimal | Minimal |
| Risk of PIH (Pigmentation) | Medium | Low | High (on dark skin) |
| Average Cost (SGD/session) | $80–$300 | $100–$500 | $120–$600 |
Verdict:
For most Singaporean skin tones (Fitzpatrick III–V), the Diode Laser remains the most balanced and effective option — safe, precise, and long-lasting.
Combination Laser Systems
In 2025, many advanced clinics use dual-wavelength or combination systems that integrate Alexandrite (755 nm) and Nd:YAG (1064 nm) or Diode (810 nm) into one platform.
These hybrid systems automatically adjust to skin tone, hair thickness, and body area — making treatments more efficient and safer than ever before.
Benefits of Combination Systems
- Customisable settings for different skin types
- Reduced number of total sessions
- Uniform energy delivery for consistent results
Dr Plus Clinic Singapore integrates this kind of technology to provide optimal results tailored for each individual.

Common Myths About Laser & IPL
Myth 1: IPL and laser hair removal are the same.
Fact: IPL uses broad-spectrum light; lasers use focused wavelengths. Lasers are more precise and safer for darker skin.
Myth 2: One session is enough.
Fact: Hair grows in cycles; you’ll need 6–10 sessions for full reduction.
Myth 3: It’s painful.
Fact: Modern systems use cooling devices and topical numbing to make sessions very tolerable.
Myth 4: Lasers aren’t safe for Asian skin.
Fact: Diode and Nd:YAG lasers are specifically engineered for Asian skin safety.
