Can Pico Laser Treat Sun Spots and Uneven Skin Tone?
Pico laser can fade some sun spots and improve uneven tone by targeting pigment. See which spots respond, how many sessions you may need, and what to expect afterward.
Key facts
- Picosecond laser pulses are measured in trillionths of a second and can be used to target selected benign pigmented lesions.
- A 2025 systematic review of solar lentigines reported response rates of 67.9% to 93.02% across the included picosecond laser studies.
- Cutera describes PICO Genesis skin revitalization as a treatment approach commonly involving 2 to 3 sessions.
Pico laser can help fade sun spots and improve some types of uneven skin tone using ultra-short pulses measured in picoseconds, or trillionths of a second. Some spots improve after 1 treatment, while broader pigmentation may require several sessions.
The results depend on your skin type, the cause of the pigmentation, and the laser settings selected.
What is pico laser, and how does it treat pigmentation?
Pico laser is an advanced laser technology designed to target unwanted pigment in the skin.
Unlike traditional lasers that deliver energy over longer pulses, picosecond lasers produce extremely short bursts of energy. These pulses create a photoacoustic effect that helps fragment pigment into smaller particles.
Over time, the body's natural processes help clear the fragmented pigment, potentially making dark spots less noticeable.
At Ideal Body Clinic, the Cutera enlighten® laser platform is used for pigment-related treatments and other applications.
The system offers multiple wavelengths, including 532 nm and 1064 nm, which can be selected according to the type and location of pigment and the patient's skin characteristics.
Health Canada lists the ENLIGHTEN LASER SYSTEM under medical device licence number 96498. The manufacturer's instructions specify different skin-type indications depending on the wavelength.
The technology is also featured in our Cutera enlighten laser treatments in Montreal.
Although the same laser platform may be used for tattoo removal and pigmentation treatments, the settings and clinical objectives differ.
What types of dark spots can pico laser remove?
Not every brown mark is the same.
The first step toward successful pigmentation treatment is understanding what caused the discoloration.
Can pico laser remove sun spots and age spots?
Sun spots, medically called solar lentigines, are flat areas of increased pigmentation associated with cumulative ultraviolet exposure.
They commonly appear on the face, hands, chest, and other sun-exposed areas.
Picosecond lasers have demonstrated encouraging results for these lesions.
A 2025 systematic review of 41 clinical trials involving 3,234 participants reported improvement rates ranging from 67.9% to 93.02% across the picosecond laser studies included.
These figures represent outcomes from different clinical studies and should not be interpreted as a guaranteed clearance rate for an individual patient.
The effectiveness of treatment depends on the characteristics of the spots and the selected protocol.

Can pico laser improve freckles?
Some freckles and other superficial benign pigmented lesions may respond to appropriately selected pigment-targeting laser treatment.
However, freckles are influenced by genetics and sun exposure.
Even when existing spots become lighter, new pigmentation may appear with continued ultraviolet exposure.
The clinician must first establish that each lesion is benign and appropriate for cosmetic treatment.
Does pico laser work for acne marks?
Dark marks that remain after acne are commonly called post-inflammatory hyperpigmentation.
These marks result from excess pigment produced after inflammation.
Pico laser may be considered in selected cases, but it is not always the first treatment recommended.
Some patients benefit more from topical skincare and protection against further inflammation.
Laser treatment can also cause additional pigmentation if the skin reacts poorly.
For patients whose primary concern is active acne rather than residual dark marks, AviClear acne laser treatment addresses a different aspect of skin health.
The right approach depends on whether the concern is active acne, residual pigment, or scarring.
Can pico laser treat melasma?
Melasma requires particular care because it behaves differently from ordinary sun spots.
It typically appears as irregular brown or grey-brown patches, often on the cheeks, forehead, and upper lip.
Hormonal influences, ultraviolet exposure, and other factors can contribute to its development.
Melasma is frequently chronic and can return after treatment.
Although picosecond lasers may improve certain cases, research does not establish them as the best treatment for every patient.
A 2023 meta-analysis involving six randomized clinical trials found that 1064 nm picosecond laser treatment reduced melasma severity scores, although results varied considerably between studies.
A separate 2026 meta-analysis of five randomized trials involving 139 patients found that a topical triple-combination cream outperformed the 755 nm picosecond alexandrite laser for melasma. Post-inflammatory hyperpigmentation was also more common in the laser-treated group than in the topical-treatment group.

This distinction matters.
Treating melasma too aggressively can sometimes make the pigmentation more noticeable.
A clinician may recommend topical pigmentation management and strict sun protection before considering a laser.
For many patients, long-term control is more realistic than expecting permanent removal.
How many pico laser sessions will I need?
The recommended number of sessions depends on the diagnosis and the desired outcome.
For isolated sun spots, noticeable improvement may occur after one treatment. Additional sessions may be recommended if pigment remains.
For widespread sun damage and uneven skin tone, a series of treatments is often considered.
Cutera describes its PICO Genesis skin revitalization approach as generally involving two to three sessions, although this is a manufacturer-described protocol rather than a universal requirement.
Skin concern
Treatment planning
Individual sun spots
One session may help; reassessment determines whether more treatment is needed
Diffuse pigmentation
A series of sessions may be appropriate
Uneven skin tone
Depends on the cause and extent of discoloration
Melasma
Individualized plan, often including non-laser care and ongoing maintenance
Post-acne dark marks
Depends on inflammation, skin type, and response to skincare
Photographs may be taken before treatment to help assess improvement.
The aim is to establish a realistic treatment plan rather than recommend the same package to every patient.
Does pico laser hurt, and how long is recovery?
During treatment, patients may feel brief snapping or warming sensations as the laser energy reaches the skin.
Discomfort varies depending on the treated area, settings, and individual sensitivity.
For superficial pigmentation, recovery is often relatively limited compared with deeper ablative resurfacing procedures.
However, possible treatment reactions include redness, mild swelling, temporary darkening of pigmented spots, crusting, and skin sensitivity.
Less common complications include blisters, infection, post-inflammatory hyperpigmentation, hypopigmentation, and scarring.
The Cutera enlighten manufacturer information explicitly identifies these possible reactions and emphasizes careful patient selection.
A shorter recovery period does not eliminate these risks.
What should I do after pico laser treatment?
Good aftercare is important, especially when treating pigmentation.
The skin may be more sensitive following laser exposure. Your treating professional should provide specific instructions based on the treatment performed.
General recommendations may include:
Cleanse gently without scrubbing.
Use a simple moisturizer recommended by your provider.
Avoid picking at any crusting or peeling skin.
Protect treated areas from ultraviolet exposure.
Delay exfoliating acids, retinoids, and other potentially irritating products until cleared by your provider.
Contact the clinic if you experience unexpected blistering, increasing pain, or signs of infection.
Daily broad-spectrum sunscreen is an important component of long-term pigmentation management.
Avoiding additional sun damage helps protect the improvements achieved with treatment.
Is pico laser safe for darker skin tones?
Pico laser may be suitable for different skin tones, but the correct wavelength and settings are essential.
Darker skin contains more epidermal melanin. This can increase the likelihood that laser energy will affect surrounding tissue as well as the intended pigment.
Possible complications include unwanted darkening or lightening of the skin.
Cutera lists different approved skin-type ranges for different enlighten III wavelengths. For example, the manufacturer's indications include Fitzpatrick types I to VI for treatment of benign pigmented lesions at 1064 nm, compared with types I to IV for the 532 nm wavelength.
These indications should not be interpreted as meaning that every pigmentation condition is suitable for treatment.
A skin assessment should consider recent sun exposure, pigmentation history, medication use, and prior reactions to cosmetic procedures.
Who should avoid pico laser treatment?
Not every pigmented area should be treated with a cosmetic laser.
A suspicious mole or changing pigmented lesion requires medical assessment before treatment.
Warning signs such as asymmetry, irregular borders, changing colour, increasing size, or bleeding should be evaluated by a qualified healthcare professional.
The manufacturer's contraindications and precautions also identify pregnancy, treatment for skin cancer, active wound infections, certain medications, and histories of abnormal pigmentation or scarring as relevant considerations.
A qualified clinician must determine whether treatment is appropriate.
If the lesion is uncertain, medical diagnosis comes before cosmetic improvement.
Is pico laser better than IPL or other skin treatments?
Pico laser and intense pulsed light (IPL) can both be used for selected pigmentation concerns, but they work differently.
Pico laser delivers energy through very short laser pulses targeting specific chromophores.
IPL delivers a broader spectrum of light and may be considered for certain types of sun damage, pigmentation, and redness.
For patients whose concerns include visible redness as well as pigmentation, the Excel V and Laser Genesis treatment options may be relevant to discuss.
A pigmentation-focused treatment is not necessarily the best choice for texture, enlarged pores, or deep scarring.
The condition being treated should determine the technology selected, not the other way around.
How much does pico laser for pigmentation cost in Montreal?
At Ideal Body Clinic, previously listed treatment pricing includes:
Pico/Genesis: $250 per session.
Enlighten: Four sessions for $800.
These are previously supplied clinic prices and must be reconfirmed before publication.
Final pricing can depend on the area being treated, the specific procedure, and whether the plan involves isolated spots or more extensive pigmentation.
A consultation can clarify which treatment is appropriate and how many sessions may be recommended.
Is pico laser worth considering for sun spots and uneven skin tone?
Pico laser is an evidence-supported option for certain benign pigmented lesions, particularly solar lentigines.
For melasma and post-inflammatory pigmentation, treatment decisions are more complex and may involve skincare, sun protection, and careful follow-up.
The best starting point is to identify the cause of the discoloration.
With a proper assessment and realistic expectations, your treatment plan can focus on the concerns that matter to you while respecting the needs of your skin.
Results vary from person to person and are not guaranteed. Nothing here is medical advice — book a consultation and we will look at your case.
