Key Takeways:
- PicoSure is a picosecond laser developed by Cynosure that operates at a trillionth of a second, representing a shorter pulse duration compared to earlier nanosecond-based laser systems.
- This speed underpins what is described as PressureWave technology, a pressure-based mechanism that interacts with the treatment area differently to heat-reliant laser systems.
- Understanding the science behind PicoSure is a reasonable starting point, but whether it is appropriate for your skin and concerns can only be determined through a consultation with a qualified medical professional.
Many people exploring PicoSure laser reach a similar point. They understand it is a laser used in aesthetic contexts, however the science behind it may remain unclear. Terms such as picosecond and PressureWave are often mentioned without detailed explanation.
This post will help you understand the technology behind PicoSure: what those terms mean, where PicoSure sits in the evolution of laser science, and why the physics behind it matter.
What is PicoSure laser technology?
PicoSure is a picosecond aesthetic laser developed by Cynosure, first introduced in 2012 as an early picosecond laser cleared for cosmetic use. It operates at two primary wavelengths, 755nm and 532nm, which may allow practitioners to target different chromophores within the treatment area depending on the concern being addressed.
What distinguishes PicoSure as a technology is not simply its wavelengths, but the speed at which it delivers energy. That speed is measured in picoseconds and is considered a key factor in how it differs from earlier generations of laser systems.
When considering PicoSure laser treatment within the broader landscape of cosmetic aesthetics, understanding what this speed represents may provide useful context.
What is a Picosecond?
A picosecond is one trillionth of a second. To put that in perspective, a picosecond is to one second what one second is to approximately 31,700 years. It represents an extremely short unit of time that can be difficult to conceptualise in practical terms.
Traditional laser systems operate in nanoseconds, which are one billionth of a second. Using a similar comparison, a nanosecond relates to one second in the way that one second relates to approximately 31.7 years. When compared, picosecond pulse durations are considerably shorter than those used in earlier nanosecond-based systems.
This difference is considered an important factor in how picosecond laser technology may behave compared to earlier systems, and highlights the relevance of energy delivery speed when comparing different laser technologies.
The significance of that difference may be better understood when exploring what is described as PressureWave technology and how it may interact with the treatment area.
What is PressureWave technology?
PressureWave is the patented mechanism central to how PicoSure interacts with the treatment area. It is associated with the delivery of energy at picosecond speeds, and is considered one factor that differentiates PicoSure’s approach from laser systems that rely primarily on heat.
When energy is delivered at very short pulse durations, the interaction with the target may shift from primarily thermal effects toward a more mechanical-based interaction. Rather than relying predominantly on heat, the ultra-short pulse can generate a pressure-based effect that interacts with the target in a different way. Cynosure refers to this photomechanical effect as PressureWave technology.
The practical significance of this distinction is that the treatment area may be exposed to a different thermal profile, compared to systems that rely more heavily on heat. In this context, energy delivery is described as involving a pressure-based component rather than sustained heat, which may influence the nature of the interaction.
What that mechanical interaction may represent at a deeper level, and its role in how PicoSure laser works, can be explored further.
What Is the difference between PicoSure and traditional lasers?
One of the key differences between PicoSure and traditional laser systems comes down to mechanism. Older nanosecond laser technologies rely primarily on photothermal action, delivering heat to the target area to interact with pigment or other structures within the treatment area. They have a well-established role in cosmetic laser practice and continue to be used effectively for a range of clinical contexts.
PicoSure operates on a photomechanical principle. Rather than heat, the ultra-short picosecond pulse creates a pressure-based interaction with the target. The two approaches are not interchangeable, and neither is universally superior. They are different tools designed around different mechanisms, and clinical context determines which is more appropriate for a given concern.
Another distinction is pulse duration. Nanosecond systems deliver energy over a comparatively longer window, while picosecond pulses occur over a much shorter duration. This difference may influence how the energy interacts with the treatment area. Whether that distinction is relevant to your specific concern is a clinical consideration rather than a straightforward comparison.
A consultation with a qualified medical professional is the only way to determine which approach is appropriate for your skin and circumstances.
Professional standards at Luxe Lips
Luxe Lips is a cosmetic clinic in Melbourne where care is grounded in medical ethics and clinical responsibility. Every treatment pathway is approached as a medical process, with established health protocols and safety guiding each step.
Across our clinics in Moonee Ponds, Camberwell, and Brighton, our medical professionals carry out a thorough screening process for every person. This includes reviewing medical history, assessing anatomical suitability, and considering psychological readiness. In line with local guidelines, this evaluation helps determine whether a proposed plan aligns with your health.
Medical professionals proceed only when a treatment is clinically appropriate. If a procedure does not align with your anatomy or health profile, we will explain why and discuss what that means for you. The focus is always on clear information and maintaining a clinical environment where safety and ethical standards come first.
Because responses and circumstances vary, a consultation is required to determine suitability before PicoSure laser treatment is considered.
Questions we’re often Asked about PicoSure laser
PicoSure is used in the context of a range of cosmetic skin concerns, including pigmentation, sun damage, uneven skin tone and texture, enlarged pores, acne scarring, and unwanted tattoos. Its two primary wavelengths, 755nm and 532nm, may allow practitioners to target different chromophores within the treatment area depending on the concern being addressed.
Response varies between individuals and is shaped by baseline skin condition, the nature of the concern, and clinical assessment. No single laser platform addresses every concern in the same way or to the same degree.
Whether PicoSure is appropriate for your specific concern requires an assessment with a qualified medical professional before any treatment is considered.
Pre-treatment preparation may influence how the treatment area responds. As a general guide, sun exposure, fake tan, and skin-sensitising products such as retinoids and strong acids are often avoided in the period leading up to a session. Certain medications and supplements may also affect how the treatment area responds, which is why a full medical history is reviewed during consultation.
Australian health regulations advise consumers to disclose all medications and supplements to their treatment provider before any laser session, as certain substances may affect sensitivity and healing response.
Pre-treatment instructions are personalised. A medical professional will provide specific guidance based on your health history and the nature of your planned session during your consultation.
PicoSure and CO2 laser are fundamentally different technologies serving different clinical purposes. CO2 laser is an ablative system, meaning it works by removing the outer layer of the treatment area to stimulate a wound healing response. It has a well-established role in addressing deeper skin concerns and continues to be used in clinical practice.
PicoSure is a non-ablative picosecond laser. It does not remove surface tissue. Instead, it delivers energy via a pressure-based mechanism designed to interact with the treatment area without ablating the surface. The two are not interchangeable and neither is universally preferable. Clinical context, skin type, the nature of the concern, and recovery tolerance all influence which approach a medical professional may consider appropriate.
These are two distinct tools with different mechanisms, different recovery profiles, and different applications. Which is more relevant to your circumstances should be discussed with your qualified medical professional during a personalised consultation
The distinction relates to how the laser interacts with the surface of the treatment area. Ablative lasers remove the outermost layers of the skin, creating a controlled wound healing response that is associated with tissue regeneration. They are often used in the context of deeper concerns but may involve a more significant recovery period.
Non-ablative lasers leave the surface intact, working beneath it to interact with underlying structures without removing tissue. Recovery is generally less involved, though the nature of the interaction with the treatment area differs accordingly. As peer reviewed clinical literature on laser resurfacing technologies notes, neither approach produces identical outcomes, and selection depends on the individual’s concerns, skin type, and clinical context.
PicoSure sits within the non-ablative category. Whether that makes it the appropriate choice for your concerns is determined during a consultation with a qualified medical professional.
At a technology level, PicoSure delivers ultra-short pulses of energy to the treatment area at picosecond speed. Rather than relying primarily on heat, the device is described as generating a pressure-based mechanical effect through PressureWave technology, which is designed to interact with pigment and tissue structures with a different thermal profile compared to some earlier laser systems.
What that mechanical interaction may represent at a cellular and tissue level, and how the skin responds in context, extends beyond the technology description alone.
Whether PicoSure is appropriate for your skin and concerns is a question best answered through a consultation with a qualified medical professional.
