17 Nov Advancements in Picosecond Laser Technology Reduce Scarring Risk in Modern Tattoo Removal
The field of laser dermatology has undergone significant evolution over the past decade, particularly in the area of tattoo removal. While early-generation lasers were associated with higher risks of thermal injury, pigment alteration, and inconsistent outcomes, modern picosecond devices have reshaped expectations for both safety and efficacy.
BARE Laser & Skin, an aesthetic laser clinic recently expanded its London, Ontario laser tattoo removal treatment service availability following increased patient demand for tattoo and pigment removal. Under the direction of Advanced Laser Technician and Trainer Lindsay Meldrum, the clinic utilizes the Cynosure PicoSure® Pro, a picosecond laser system engineered to reduce heat exposure while increasing pigment fragmentation efficiency.
This shift reflects a broader trend across dermatology and aesthetic medicine: a move toward precision-based energy delivery that improves patient outcomes and minimizes adverse events.
Picosecond Lasers: A Significant Advancement in Dermatologic Safety
Traditional nanosecond Q-switched lasers rely on photothermal energy to break down pigment. While effective, they generate higher levels of heat, potentially increasing the risk of tissue damage and post-inflammatory changes. Picosecond lasers, by contrast, rely primarily on a photomechanical “pressure wave” mechanism. This allows:
- More effective ink shattering, producing smaller particles that the lymphatic system can clear efficiently
- Lower heat buildup, reducing the likelihood of epidermal and dermal trauma
- Improved outcomes for difficult pigments, including cosmetic tattoo inks and resistant blues/greens
- More predictable healing trajectories for a wide range of skin types
The PicoSure® Pro system used by BARE Laser & Skin has been recognized for its consistent energy delivery and the clinical stability of its pulse profile—key factors in minimizing adverse reactions.

Evaluating Scarring Risk in Tattoo Removal: Clinical Considerations
One of the most common patient concerns relates to scarring potential. Historical cases of scarring often stemmed from improper device settings, operator error, or pre-existing scar tissue created during the tattooing process itself.
Based on her clinical experience, Meldrum addresses this concern directly:
“When performed correctly, laser tattoo removal rarely causes scarring,” Lindsay says.
“‘If scarring exists, it could potentially be from the tattoo itself, resulting from the artists’ technique. When performed correctly, laser tattoo removal rarely causes scarring. Proper aftercare plays a huge role in ensuring smooth healing.”
This distinction is important for clinicians counseling patients on expected outcomes. Thermal injury risk has decreased significantly with the adoption of picosecond pulse durations, though appropriate patient selection, medical history review, and accurate fluence settings remain essential.
For a more detailed examination of scarring risk and prevention strategies, readers may refer to the clinic’s in-depth guide on whether laser tattoo removal causes scarring.
The Role of Aftercare in Healing Quality and Scar Prevention
Post-treatment care remains one of the strongest determinants of healing outcomes. Regardless of device type, epidermal disruption and transient inflammation occur as part of the normal healing cascade. Patients must be advised to:
- Avoid picking or scratching the treated area
- Keep the site clean and protected
- Minimize sun exposure to reduce pigment alteration risks
- Monitor for atypical inflammation
- Use recommended topical agents when instructed
Failure to follow aftercare instructions can increase the risk of complications such as delayed healing or textural changes, even with advanced laser systems.
Permanent Makeup and Cosmetic Tattoo Removal
Cosmetic tattoo removal—including microblading—presents a unique challenge due to pigment composition and depth variance. The PicoSure® Pro has demonstrated improved compatibility with cosmetic pigments, making removal safer for sensitive areas such as the brows and face.
BARE Laser & Skin incorporates PMU (permanent makeup) removal into its clinical services, and Meldrum also provides training to emerging technicians, helping standardize safe practices within the industry.
Conclusion: Clinical Implications for Dermatology and Aesthetic Medicine
The expanding use of picosecond laser systems represents a meaningful improvement in the risk profile associated with tattoo removal. For patients concerned about scarring, modern systems—when paired with properly trained operators and structured aftercare—offer significantly improved safety.
As patient demand increases, clinics adopting advanced technologies such as the PicoSure® Pro are better equipped to deliver predictable outcomes with minimal complications. The experience at BARE Laser & Skin reflects this broader movement toward scientifically grounded, patient-centered laser care.
