PicoSure is a picosecond laser from Cynosure that breaks up pigment and tattoo ink mainly with a pressure wave rather than heat, and its Focus Lens is used to stimulate collagen for fine lines and acne scars. Pigment often needs 1-3 sessions and texture concerns 3-5; redness usually fades within hours to a day, and results vary.
In the evolving landscape of aesthetic medicine, few technologies have shifted the paradigm as significantly as the picosecond laser. At Richmond Anti-Aging Clinic (RAAC) in Richmond, BC, we prioritize treatments backed by rigorous clinical data and physiological evidence. PicoSure, developed by Cynosure, represents a departure from traditional laser mechanisms, moving away from heat-based destruction toward a more refined, photomechanical approach. Before diving into the physics, you can Learn more about PicoSure on our dedicated treatment page. Under the clinical oversight of Dr. Charles Jiang, a licensed physician with over 29 years of clinical experience, our clinic approaches PicoSure not just as a tool, but as a sophisticated biological modulator. This article explores the biochemical and physical mechanisms behind PicoSure's use for skin revitalization and pigment correction in 2026.
How does the PicoSure picosecond laser work?
PicoSure delivers energy in trillionths of a second, creating a pressure wave that shatters pigment or ink into tiny particles the body can clear, with less heat reaching surrounding skin than older nanosecond lasers.
To understand why PicoSure is distinct, one must first understand the concept of "Pulse Duration." Traditional lasers, such as Q-switched systems, operate in the nanosecond range (one-billionth of a second). While effective, nanosecond lasers rely heavily on the photothermal effect—using heat to break down pigment or stimulate collagen. The challenge with heat is the risk of collateral damage to surrounding tissue, which can lead to longer recovery times or post-inflammatory hyperpigmentation (PIH), especially in diverse skin types found here in Richmond. PicoSure operates in the picosecond domain (one-trillionth of a second). This speed is critical because it is faster than the Thermal Relaxation Time (TRT) of most skin structures. By delivering energy in such incredibly short bursts, PicoSure creates a "PressureWave™."
Photomechanical vs. Photothermal
Instead of burning or heating the target—whether it be a tattoo ink particle or a cluster of melanin—the PressureWave™ shatters the target into microscopic, dust-like particles. This is known as a photomechanical effect. Once the pigment is pulverized, the body’s lymphatic system can more efficiently clear the debris. Because the pulse is so fast, there is minimal heat transfer to the surrounding dermis, significantly reducing the risk of burns and minimizing downtime.
How does the PicoSure Focus Lens improve skin texture?
The Focus Lens concentrates energy into tiny zones beneath an intact skin surface, which is thought to signal nearby cells to produce new collagen and elastin, helping fine lines and acne scars without an open wound.
A distinctive component of the PicoSure system is the Focus Lens Array. This diffractive lens redistributes the picosecond energy into high-intensity and low-intensity areas. When the high-intensity beams hit the skin, they create Laser-Induced Optical Breakdowns (LIOBs) in the epidermis. These are essentially microscopic cavities created by the pressure wave. Crucially, these LIOBs do not break the surface of the skin (the stratum corneum remains intact).
Biochemical Response
Research into the Focus Lens mechanism suggests that these LIOBs trigger a biological "cell signaling" response. The pressure wave sends a distress signal to neighboring cells, which stimulates the production of new collagen and elastin. This process, often referred to as skin revitalization, allows for the treatment of fine lines, wrinkles, and acne scars without the aggressive "raw" healing phase associated with ablative CO2 lasers.

What does the research say about PicoSure?
Published studies suggest picosecond pulses may clear blue and green tattoo ink in fewer sessions than nanosecond lasers, the Focus Lens may increase collagen and elastin, and pigment can be reduced with a lower risk of rebound.
The efficacy of PicoSure is documented in numerous peer-reviewed journals. At Richmond Anti-Aging Clinic (RAAC), we base our protocols on these evidence-based findings:
- Archives of Dermatology: This study examined the use of picosecond pulses compared with nanosecond pulses for the clearance of blue and green tattoo inks. The study highlighted that the photomechanical impact was the primary driver of success, requiring fewer treatment sessions.
- Lasers in Surgery and Medicine: This research focused on the Focus Lens Array for the treatment of facial wrinkles and acne scars. The researchers found significant increases in collagen and elastin density within the dermal layers, concluding that the LIOB-induced cell signaling was a safe and effective alternative to more invasive resurfacing.
- Journal of the American Academy of Dermatology (JAAD): This study evaluated the use of picosecond technology for treating melasma and other pigmentary disorders. The results showed that PicoSure could achieve significant pigment reduction with a lower risk of rebound hyperpigmentation compared to traditional heat-based lasers.
How does PicoSure compare with Q-switched and CO2 lasers?
PicoSure relies on pressure rather than heat, so it generally means shorter recovery and lower PIH risk than Q-switched or ablative CO2 lasers, while CO2 remains better suited to deep wrinkles and severe laxity.
| Feature | PicoSure (Picosecond) | Q-Switched (Nanosecond) | CO2 (Ablative) |
|---|---|---|---|
| Primary Mechanism | Photomechanical (Pressure) | Photothermal (Heat) | Thermal Ablation (Vaporization) |
| Downtime | Minimal (2-24 hours redness) | Moderate (3-7 days) | Significant (7-14 days) |
| Risk of PIH | Very Low | Moderate | High (on darker skin) |
| Best For | Pigment, Scars, Wrinkles, Tattoos | Tattoos, General Pigment | Deep Wrinkles, Severe Laxity |
| Cell Signaling | Yes (via Focus Lens) | No | No |
Who is a good candidate for PicoSure?
PicoSure may suit people with sun spots, freckles or melasma, acne scars or fine lines, or tattoos, including many darker skin types; active infections, some autoimmune conditions and recent photosensitising medication may rule it out.
At Richmond Anti-Aging Clinic (RAAC), candidate evaluation is a medical process. Dr. Charles Jiang and our clinical team utilize the Fitzpatrick Skin Scale and digital skin analysis to determine the appropriate settings.
Who is a Candidate?
- Pigment Concerns: Individuals with sunspots, freckles, or melasma.
- Texture Issues: Those looking to improve acne scarring or fine lines.
- Tattoo Removal: Clients seeking faster clearance of stubborn ink.
- All Skin Types: Because PicoSure is photomechanical, it is generally safer for Fitzpatrick types IV-VI (darker skin tones) than many other lasers.
Limitations & Contraindications
While PicoSure is versatile, it may not be suitable for individuals with active skin infections, certain autoimmune conditions, or those who have recently used photosensitizing medications. During your evaluation, Dr. Jiang will review your medical history to ensure safety. For acne scars or skin revitalization, a series of 3-5 sessions is typically recommended. Book a Consultation at our Richmond clinic to receive a personalized assessment.
Does PicoSure hurt, and what is recovery like?
Most people describe a quick rubber-band snap, with numbing cream available; mild redness and swelling usually settle within a few hours to a day, and pigment may darken slightly before flaking off.
- Preparation: The skin is cleansed, and in some cases, a topical numbing cream is applied.
- The Procedure: The handpiece is moved across the treatment area. You may feel a sensation similar to the snapping of a small rubber band.
- Immediate Aftercare: You will likely experience mild erythema (redness) and slight swelling, similar to a mild sunburn. This typically resolves within a few hours to a day.
- The Timeline: Pigment often darkens slightly before flaking off or being absorbed by the body. Collagen remodeling continues for weeks following the session.
