Comparing Pico Laser Types — PicoSure, PicoWay, and Enlighten Explained
Pico lasers refer to a category of devices that deliver energy in picosecond pulses (trillionths of a second), far shorter than the nanosecond pulses used in older pigment lasers. Shorter pulse duration is generally understood to reduce heat buildup and rely more on a photomechanical effect, which may break down pigment particles into finer fragments while potentially limiting damage to surrounding tissue. That said, the term 'pico laser' covers several manufacturers and models with different wavelength combinations, pulse delivery methods, and handpiece attachments, so actual clinical application can vary.
What are the basic differences between PicoSure, PicoWay, and Enlighten?
PicoSure is built around a 755nm alexandrite wavelength and is known as one of the first commercially available picosecond lasers. PicoWay is described as combining multiple wavelengths — 532nm, 730nm, and 1064nm — designed to address a range of skin tones and pigment depths. Enlighten uses two wavelengths, 532nm and 1064nm, and is said to offer adjustable pulse durations depending on the treatment goal. All three share picosecond-level delivery, but differences in wavelength lineup and handpiece configuration may affect which pigment lesions and depths each device is best suited for.
How does pico toning differ from conventional laser toning?
Pico toning uses a picosecond laser at low fluence applied repeatedly over a broad area, similar in concept to conventional nanosecond-based laser toning, but with a much shorter pulse duration. In theory this may reduce thermal damage while altering how efficiently pigment particles are broken down, but actual improvement and recovery time vary considerably depending on skin type, the type and depth of the pigment lesion, and the number of sessions. Which device suits a particular person is something that should be determined after an in-person skin evaluation.
What should be checked before a pigment laser procedure?
Pigment lesions vary widely — melasma, freckles, sunspots, age spots, and nevus of Ota, among others — and the depth of the lesion (epidermal versus dermal) can affect which wavelength and delivery method are appropriate. Even with the same pico laser, an unsuitable wavelength choice or energy setting may result in less improvement than expected, or in rare cases, temporary post-inflammatory hyperpigmentation. Accurate diagnosis of the lesion beforehand is important, and avoiding sun exposure along with consistent sunscreen use may support recovery and help maintain results.
Does a single pico laser session provide lasting results?
The number of sessions needed varies depending on the type and depth of the pigment lesion, and multiple sessions spaced several weeks apart are often required. Continued sun exposure or skin irritation after treatment can cause pigment to darken again or new lesions to form, so it would be inaccurate to say results last indefinitely. How long results are maintained can differ based on individual skin response and lifestyle habits.
Are there any precautions for aftercare?
Temporary redness, swelling, or fine crusting can occur right after treatment, and these are generally understood to resolve naturally over time. Recovery speed and response vary between individuals, so if unusual symptoms persist or seem more severe than expected, it is safer to contact the treating clinic rather than self-treating with ointments or products. Aftercare steps such as cleansing and sunscreen use should also follow the guidance provided by the treating physician.
