When it comes to addressing pigmentation and tattoo removal, Q-Switched and Pico lasers have been making waves. If you’re considering choosing either of these treatments, then it’s crucial to understand them first so you can make an informed decision and achieve the best possible results.
Allow Dr Justin Boey of Sozo Clinic to guide you through this in-depth guide to Q-Switched and Pico lasers. Let’s begin.

What are Q-Switched and Pico Lasers?
Q-Switched and Pico lasers are technologies designed to target pigmentation, reduce the visibility of tattoos and address other skin concerns. Although they have roughly similar functions, they operate with different mechanisms.
- Q-Switched Laser. Uses nanosecond pulses to deliver high-energy laser light to the skin. This laser breaks down pigmentation or tattoo ink into smaller particles that the body can naturally eliminate.
- Pico Laser. This type of laser delivers energy in picosecond pulses to address pigmentation and help in tattoo removal. This difference allows for finer particle fragmentation and potentially faster results.
Q-Switched vs. Pico Laser Characteristics:
| Laser Type | Pulse Duration | Technology | Primary Uses |
|---|---|---|---|
| Q-Switched Laser | Nanoseconds | Photothermal |
|
| Pico Laser | Picoseconds | Photoacoustic |
|
How Do Q-Switched and Pico Lasers Work?
Q-Switched Laser Technology
Q-Switched lasers emit light in short, high-energy nanosecond pulses. These pulses target the pigmentation or ink particles in the skin. Once heated, the particles break apart into smaller fragments, gradually removed by the body’s lymphatic system.
Pico Laser Technology
On the other hand, Pico lasers deliver energy at an even faster rate – picosecond pulses. This allows for more precise pigmentation targeting while reducing the chances of damage in the surrounding tissue. The smaller, shattered particles may allow quicker clearance and potentially fewer sessions.
| Feature | Q-Switched Laser | Pico Laser |
|---|---|---|
| Pulse Duration | Nanoseconds | Picoseconds |
| Energy Delivery | High-energy pulses | Ultra-short, high-energy pulses |
| Target Size Reduction | Larger pigmentation particles | Smaller pigmentation particles |
Benefits of Q-Switched and Pico Lasers
Q-Switched Laser Benefits
- It is one of the earliest technologies to be used for tattoo removal. Q-Switched laser has long been a trusted technology for reducing the visibility of tattoos. They work well when breaking down different tattoo pigments into smaller particles.
- It is more budget-friendly. Sessions are often more affordable than picosecond laser treatments, making it a cost-effective choice.
Pico Laser Benefits
- Fewer sessions. Pico lasers deliver quick outcomes by shattering pigmentations and tattoo ink into finer particles, often requiring fewer sessions.
- Less downtime. Ultra-short pulses reduce tissue damage, minimising discomfort and shortening recovery time.
| Condition | Q-Switched Laser Process | Pico Laser Process |
|---|---|---|
| Skin Pigmentation | Gradual lightening over multiple sessions | Faster lightening with fewer sessions |
| Tattoo Removal | Targets tattoo pigment by penetrating the skin and heating the ink until it disintegrates | Breaks apart tattoo ink using a photoacoustic effect |
| Skin Rejuvenation | Stimulates collagen production but with more gradual results | Promotes collagen production with shorter downtime |
What Conditions Can They Treat?
| Concern | Q-Switched Laser | Pico Laser |
|---|---|---|
| Tattoo Removal | Effective, especially for darker inks | Works faster and is ideal for multicoloured tattoos |
| Skin Pigmentation | Melasma, liver spots | Melasma, post-inflammatory hyperpigmentation |
| Acne Scars | Significant improvement | Effective in reducing the appearance of scars |
Q-Switched Laser vs Pico Laser: Which is More Effective?
When comparing their effectiveness, the ideal choice depends on the specific condition.
- For tattoo removal, Q-Switched lasers are an excellent choice, though Pico lasers have advantages for multicoloured or resistant tattoos.
- For pigmentation issues, Pico lasers generally offer a faster reduction of pigmentation.
- For acne scars, picosecond laser is considered more effective due to its precision and ability to stimulate collagen.
| Condition | Q-Switched Laser Effectiveness | Pico Laser Effectiveness |
|---|---|---|
| Tattoo Removal | Highly effective | Faster and more targeted precision |
| Pigmentation | Gradual results, requires more sessions | Quicker, more uniform results |
| Acne Scars | Limited benefits | Highly effective |
Safety and Side Effects
Both Q-Switched and Picolasers are generally safe and well-tolerated, but it’s essential to be aware of the following considerations. Here are some of the common side effects:
- Temporary redness or swelling. It is common to experience temporary redness or swelling in the treated area after laser treatment. This is usually mild and subsides within a few hours to a few days.
- Minor irritation. Some individuals may experience minor irritation following laser treatment, such as itching or dryness. This can be managed with gentle skin care and moisturisation.
Laser treatments should always be performed by trained professionals who can assess your skin condition, determine the appropriate laser energy settings and ensure your safety throughout the procedure.
It’s essential to discuss any pre-existing skin conditions, allergies, or medical history with your aesthetic practitioner before undergoing laser treatment. They can provide personalised advice and precautions based on your specific needs.
Cost Comparison
The price of Q-Switched laser sessions in Singapore varies. Depending on the clinic, the area being treated, and the specific type of treatment (e.g., pigment removal, tattoo removal), prices can range from as low as $50 to up to $500 per session. The total cost varies depending on the size and complexity of the tattoo or pigmentation.
In Singapore, picosecond laser treatments typically range from $200 to $800 per session. For most people, an average session costs between $300 and $500. The total expense for treating common skin conditions like pigmentation, scars, or tattoos with picosecond lasers can vary widely depending on the required sessions, which usually average at least five sessions.
To give you a clearer understanding of the price range for common treatments, refer to the table below:
| Treatment | Q-Switched Laser (SGD) | Pico Laser (SGD) |
|---|---|---|
| Pigmentation Removal | $50 – $500 | $200 – $800 |
| Tattoo Removal | $200 – $500 | $300 – $800 |
| Scar Treatment | $100 – $400 | $300 – $700 |
Please note that all prices listed here are approximate and can vary depending on individual factors and the specific clinic you choose. It’s always advisable to consult with a qualified aesthetic practitioner or healthcare provider to determine the most accurate pricing and treatment plan based on your specific needs and goals.
How to Choose Between Q-Switched and Pico Lasers
Here are some key considerations to guide your decision-making:
Skin Type Considerations
- Individuals with sensitive skin or a darker skin tone may benefit from Pico lasers, designed to minimise potential side effects and deliver effective results.
- On the other hand, Q-Switched lasers are generally suitable for a wide range of skin types.
Condition Severity
- Pico lasers are designed to deliver shorter pulses, which may make them more effective for addressing deeper pigmentation or stubborn tattoos.
- Q-Switched lasers are versatile tools that treat various pigmentation issues, including tattoos, scars and age spots.
Budget Constraints
- Budget is an important factor when choosing between the two laser types. Q-Switched lasers are generally more affordable.
- Picosecond lasers, being a newer technology, tend to be more expensive.
Conclusion
Q-Switched and Pico lasers treat skin concerns like pigmentation, acne scars and tattoos. While Q-Switched lasers are cost-effective and reliable, picosecond lasers may offer faster results with shorter downtime.
Ultimately, the right choice depends on individual factors like skin type, budget, and severity of the skin condition. Consult a qualified aesthetic practitioner who can tailor treatments to your unique needs for personalised advice.
