Pico Laser technology has become a recognised approach for tattoo removal in Singapore. At The Aesthetics Centre, we use the PicoWay system, which operates using picosecond pulse duration (trillionths of a second) to fragment tattoo ink beneath the skin.
The PicoWay laser uses three wavelengths to target different ink colours. Unlike older nanosecond laser systems that rely primarily on heat, picosecond technology creates pressure waves to break down ink particles. These fragmented particles are then gradually cleared by the body’s immune system.
Dr Anita Soosay performs Pico Laser tattoo removal at our clinic in Singapore. Each treatment plan is developed based on individual assessment of your tattoo’s characteristics, ink colours, and your skin type. The number of sessions required varies between patients and depends on multiple factors.

How Pico Laser Technology Works for Tattoo Removal
Pico Laser refers to laser systems that deliver energy in picosecond pulses. A picosecond is one trillionth of a second (10⁻¹² seconds), which is significantly shorter than the nanosecond pulses (10⁻⁹ seconds) used by traditional Q-switched lasers.
The Photoacoustic Effect:
When the ultra-short laser pulse hits tattoo ink, it creates rapid pressure waves rather than sustained heat. This photoacoustic effect fragments the ink mechanically, breaking it into smaller particles. Traditional nanosecond lasers work differently, using photothermal (heat-based) energy to break down pigments.
What Happens to the Ink:
Once the ink is fragmented into smaller particles, your body’s immune system recognises them as foreign material. Specialised cells called phagocytes work to clear these particles through the lymphatic system over the weeks following each treatment session.
Individual Variation:
The rate at which ink clears varies significantly between individuals. Factors including immune function, tattoo location, blood circulation in the area, and lifestyle factors all influence how quickly your body processes the fragmented ink. This is why session numbers cannot be predicted with certainty before treatment begins.
About the PicoWay Laser System
The PicoWay laser manufactured by Candela Medical is the system used at The Aesthetics Centre. This device is notified with the Health Sciences Authority (HSA) in Singapore as a medical device and is FDA-cleared for tattoo removal applications.
Technical Specifications:
| Specification | PicoWay Parameters |
| Pulse Duration | 300-450 picoseconds |
| Available Wavelengths | 532nm, 785nm, 1064nm |
| Energy Delivery Method | Photoacoustic pressure wave |
| Manufacturer | Candela Medical |
How Different Wavelengths Target Ink Colours:
The PicoWay system uses three different wavelengths, each absorbed by different ink pigments:
1064nm Wavelength (Infrared): This wavelength penetrates deeper into the skin and is absorbed by darker pigments. It is used to treat black, dark blue, and brown tattoo ink. Most professional tattoos contain significant amounts of these colours.
785nm Wavelength (Near-Infrared): This wavelength is particularly useful for green and blue pigments, which have historically been among the most challenging colours to remove. Not all picosecond laser systems offer this wavelength option.
532nm Wavelength (Green Light): This wavelength targets lighter pigments including red, orange, and yellow ink. It works on the upper layers of the dermis where these colours are typically placed.
Important Note on Ink Composition:
Tattoo inks are not standardised products. Different manufacturers use different chemical compositions, and even inks labelled as the same colour may respond differently to treatment. Some pigments, particularly fluorescent or pastel colours, may be more resistant to laser treatment regardless of the technology used.
Comparing Picosecond and Nanosecond Laser Technologies
Understanding the difference between these two laser types can help you make an informed decision about tattoo removal approaches.

Important Context:
These are general ranges based on clinical observations. Your individual experience may differ based on:
• Tattoo characteristics (size, ink density, colours, professional vs amateur)
• Your skin type and healing capacity
• Tattoo location on your body
• Your immune system function
• How consistently you follow aftercare instructions
Neither technology guarantees complete removal, and some tattoos may leave residual marks even after multiple sessions. A consultation provides realistic expectations based on your specific tattoo.
The Pico Laser Treatment Process
Initial Consultation and Assessment
During your first visit, Dr Anita Soosay will examine your tattoo and discuss your treatment goals. The assessment includes:
Tattoo Evaluation:
• Measurement of tattoo size and location
• Identification of all ink colours present
• Assessment of whether the tattoo is professional or amateur (affects ink density)
• Documentation of tattoo age
• Review of any previous removal attempts
Medical History Review:
• Current medications (some increase photosensitivity)
• Skin conditions or healing concerns
• History of keloid scarring
• Sun exposure habits
• Overall health status
Treatment Planning: Based on this assessment, Dr Soosay will discuss the likely number of sessions required, though this is an estimate. She will also explain potential risks specific to your skin type and tattoo characteristics, and answer your questions about the process.
Preparing for Your Treatment Session
In the weeks before your first session, you may be advised to:
• Avoid direct sun exposure on the tattooed area for at least 4 weeks
• Stop using products containing retinoids, AHAs, or BHAs on the treatment area if recommended
• Avoid blood-thinning medications or supplements if medically safe to do so
• Inform the clinic of any changes to your health or medications
• Shave the treatment area 24-48 hours before your appointment if hair is present
On the day of treatment, arrive with clean skin free from lotions, oils, or makeup on the tattooed area.
During Your Treatment Session
Before Laser Application: The treatment area is cleaned and photographed for medical records. If you’ve requested numbing cream, it is applied 45-60 minutes before the laser treatment begins. Protective eyewear is provided as laser safety equipment.
The Laser Treatment: The PicoWay handpiece is moved over the tattooed area, delivering ultra-short pulses of laser energy. You will hear a snapping sound with each pulse. Most patients describe the sensation as similar to a rubber band snapping against the skin, though discomfort levels vary between individuals.
Treatment duration depends on tattoo size. A small tattoo might take only a few minutes, while a large piece could take 20-30 minutes.
Immediate Response: The treated area typically shows immediate whitening, called frosting, which is a normal response to the laser. This usually resolves within 20-30 minutes. You may also notice mild redness or slight swelling.
After Treatment Care
First 24-48 Hours:
Common responses in the first few days include:
• Redness and swelling (varies by individual and location)
• Possible pinpoint scabbing
• Temporary darkening of some ink colours, particularly browns or flesh tones
• Mild tenderness in the treated area
Post-Treatment Instructions:
You will receive specific aftercare guidance, which typically includes:
• Gently cleanse the area with mild soap and water
• Apply any prescribed ointments as directed
• Avoid submerging the area in water (no swimming, baths, or hot tubs) for 48 hours
• Do not engage in strenuous exercise that causes heavy sweating for 48 hours
• Avoid direct sun exposure and apply SPF 50+ sunscreen when outdoors
• Do not pick at any scabs or blisters that may form
• Wear loose clothing over the treated area
What to Expect in Following Weeks:
As your skin heals over the 8-12 weeks between sessions, the fragmented ink particles are gradually cleared by your lymphatic system. The tattoo will continue to fade during this period. Maximum fading from each session is typically observed around 6-8 weeks post-treatment.
Follow-Up Sessions
Sessions are spaced 8-12 weeks apart. This interval is not arbitrary—it allows:
• Complete healing of the treated skin
• Your immune system time to clear fragmented ink particles
• Assessment of your response to the previous session
Attempting sessions more frequently does not accelerate results and may increase the risk of adverse effects or scarring.
Who May Benefit from Pico Laser Technology
Pico Laser tattoo removal may be considered if you have:
Specific Tattoo Challenges:
• Multi-coloured tattoos that require treatment of various pigments
• Green or blue ink that has been resistant to previous treatments
• Professional tattoos with dense ink
• Tattoos where you want to minimise thermal impact on surrounding skin
Previous Treatment History:
• Partial fading from earlier Q-switched laser sessions
• Long gaps between previous treatments requiring reassessment
• Desire to explore a different technological approach
Skin Type Considerations:
• Darker skin tones where reduced heat generation may be beneficial
• Previous experience with pigmentation changes from laser treatment
• Situations requiring adjusted treatment parameters for safety
When Pico Laser May Not Be Suitable
Individual assessment is required, but tattoo removal may not be appropriate if you are:
• Currently pregnant or breastfeeding
• Have an active skin infection or inflammation in the treatment area
• Have a history of keloid formation (requires careful evaluation)
• Taking medications that cause photosensitivity
• Have unrealistic expectations about complete removal or session numbers
• Have certain medical conditions that affect healing
A consultation with Dr Anita Soosay determines whether treatment is suitable for your specific situation.
Factors That Influence Treatment Outcomes
Tattoo-Related Factors:
Ink Colour and Composition: Black and dark blue pigments generally respond well to the 1064nm wavelength. Green and blue require the 785nm wavelength. Red, orange, and yellow are treated with 532nm. White, flesh-tone, and pastel colours may be more challenging and carry a risk of darkening.
Tattoo Age: Older tattoos may have experienced some natural fading, but ink may also have migrated deeper into the skin over time. Very fresh tattoos contain the full ink load without any natural fading.
Professional vs Amateur: Professional tattoos typically have consistent ink depth and higher density, often requiring more sessions. Amateur tattoos may have variable depth and density, sometimes responding with fewer sessions.
Body Location: Areas with better blood circulation (chest, upper back) may show faster clearing. Extremities (hands, feet, ankles) typically require more sessions due to reduced circulation.
Patient-Related Factors:
Skin Type: Treatment protocols are adjusted based on Fitzpatrick skin type. Darker skin types have different risk profiles for pigmentation changes and require modified energy settings.
Immune Function: The efficiency of your lymphatic system in clearing fragmented ink varies between individuals. Overall health, hydration, and lifestyle factors all play a role.
Lifestyle Factors: Smoking may impair healing and ink clearance. Regular exercise and adequate hydration may support lymphatic function. Sun exposure affects treatment outcomes and healing.

Frequently Asked Questions About Pico Laser Tattoo Removal
How does Pico Laser technology remove tattoos?
Pico Laser uses picosecond pulses (300–450 trillionths of a second) to fragment tattoo ink into tiny particles. The PicoWay system creates photoacoustic pressure waves that shatter ink without relying on heat, allowing the body’s lymphatic system to clear the particles naturally over time. Different wavelengths (532nm, 785nm, 1064nm) target different ink colours.
How many sessions will I need to remove my tattoo?
Most patients require 6–10 treatment sessions with Pico Laser technology, though the exact number varies based on tattoo size, ink colours, density, age, and individual skin response. Sessions are spaced 8–12 weeks apart to allow the body to clear fragmented ink particles. An assessment with Dr Anita Soosay will provide a more specific estimate for your tattoo.
Does Pico Laser tattoo removal hurt?
Patients commonly describe the sensation as similar to a rubber band snapping against the skin. Numbing cream is applied 45–60 minutes before treatment to reduce discomfort. Additional pain relief options, including cooling devices or oral pain relief, may be discussed during your consultation if needed.
What colours can Pico Laser remove?
The PicoWay system uses three wavelengths to treat different ink colours: 1064nm targets black, dark blue, and brown inks; 785nm addresses green and teal pigments; 532nm treats red, orange, and yellow colours. Individual responses vary, and some colours may require more sessions than others.
What happens immediately after treatment?
A temporary white “frosting” effect appears on the treated area, typically resolving within 20–30 minutes. Redness, mild swelling, and tenderness are common and usually subside within 1–3 days. The treated area should be kept clean, moisturised, and protected from sun exposure during healing.
How long do I need to wait between sessions?
Sessions are scheduled 8–12 weeks apart to allow the lymphatic system sufficient time to clear fragmented ink particles and for the skin to heal completely. More frequent treatments may increase the risk of skin damage without improving results.
Can Pico Laser treat all skin types?
Pico Laser technology may be suitable for various skin types, including darker skin tones. Dr Anita Soosay will assess your individual skin type, tattoo characteristics, and medical history during consultation to determine suitability and expected outcomes.
What should I do before my appointment?
Avoid sun exposure and tanning for 4 weeks before treatment. Stop using photosensitising skincare products as advised. Shave the treatment area 24–48 hours before your appointment. Arrive with clean skin, free from lotions, makeup, or perfumes. Inform Dr Anita Soosay of any medical conditions or medications during your consultation.
Who should not undergo Pico Laser tattoo removal?
Treatment may not be suitable if you are pregnant or breastfeeding, have active skin infections in the treatment area, have a history of keloid scarring, are taking photosensitising medications, or have unrealistic expectations about results. A thorough assessment will determine your suitability.
How does Pico Laser compare to older Q-Switched lasers?
Pico Laser delivers energy in picosecond pulses (300–450 trillionths of a second), while Q-Switched lasers use nanosecond pulses (5–20 billionths of a second). The shorter pulse duration of Pico Laser creates photoacoustic pressure waves rather than photothermal effects, which may result in more efficient ink fragmentation. Pico Laser treatments typically require 6–10 sessions compared to 8–15 sessions with Q-Switched technology, though individual results vary.
