Quick answer: PicoSure is a picosecond laser used to treat sun spots, freckles, acne marks, and overall dullness. It delivers energy in ultra-short pulses, which targets pigment with relatively low heat — making it a popular option for patients who want visible brightening with minimal downtime.

Pigmentation can be frustrating to treat because not all dark spots are the same. Sun spots, freckles, and post-acne marks often respond well to picosecond lasers like PicoSure, while other pigmentation types — melasma, redness-related discoloration — need a different approach entirely. This guide focuses on what PicoSure treats, how it works, and who's a good candidate.

What Causes Pigmentation?

Pigmentation happens when the skin produces too much melanin, or when inflammation leaves behind dark marks after healing. Common causes include sun exposure, hormonal changes, acne, irritation, and skin injury.

Some pigmentation sits on the surface, while other types go deeper into the skin. Surface-level concerns — like sun spots and freckles — are generally where PicoSure performs best.

What Is PicoSure?

PicoSure is a picosecond laser, meaning it delivers energy in trillionths-of-a-second pulses rather than the longer pulses used by older laser generations. This ultra-short pulse duration targets pigment with a photomechanical (pressure-based) effect rather than heat, which is why it's associated with less thermal damage to surrounding skin and generally faster recovery.

What Does PicoSure Treat?

PicoSure is commonly used for:

Sun spots — flat brown spots from cumulative UV exposure
Freckles — genetic or sun-related pigment concentrations
Acne marks — flat, brown post-inflammatory marks left after acne heals
Overall dullness and uneven tone — general brightening over a course of sessions

It's a popular option for patients who want visible improvement with minimal downtime and a brighter, more even tone over time.

What PicoSure Is Not Typically Used For

To set accurate expectations: PicoSure is not the go-to choice for melasma (which usually needs a more cautious, specialized approach) or for pigmentation combined with visible redness or blood vessels (which typically responds better to vascular-targeting devices). If your main concern is melasma or redness alongside pigment, that's exactly what a consultation is for — matching your specific condition to the right treatment rather than defaulting to one device.

Is PicoSure Safe for Darker Skin Tones?

PicoSure works best on lighter to medium skin tones. For darker skin tones, PicoSure isn't typically recommended at Forena Clinic due to a higher risk of complications, including post-inflammatory hyperpigmentation. This isn't a limitation of effort or effectiveness — it's a safety-first approach based on how different skin tones respond to this particular wavelength and pulse duration.

This is exactly why a proper consultation matters: our doctors assess your skin type and pigment pattern first, and will recommend an alternative treatment approach if PicoSure isn't the right fit for your skin tone.

What to Expect After Treatment

Most PicoSure treatments involve mild redness, warmth, or temporary darkening of spots before they fade over the following days to weeks. Some patients need multiple sessions for the best result, especially for deeper or more stubborn pigment.

Aftercare matters just as much as the laser itself:

Use sunscreen daily
Avoid heat and direct sun exposure
Don't scrub or exfoliate too soon
Follow your clinic's skincare instructions carefully

Frequently Asked Questions

What does PicoSure treat? Sun spots, freckles, acne marks, and overall dullness or uneven tone.

Is PicoSure suitable for all skin tones? PicoSure works best on lighter to medium skin tones. For darker skin tones, PicoSure isn't typically recommended at Forena Clinic due to a higher risk of complications such as post-inflammatory hyperpigmentation. A consultation helps determine the right approach for your skin.

Is PicoSure used for melasma? PicoSure is not typically the go-to choice for melasma, which usually needs a more cautious, specialized approach. A consultation can determine the right treatment for melasma specifically.

How many sessions does PicoSure take? This varies by patient and pigment depth. Some see improvement after one session, while deeper or more stubborn pigment may need multiple sessions spaced several weeks apart. Your doctor will outline a plan during consultation.

Does PicoSure hurt? Most patients describe a mild tingling sensation rather than significant pain. Numbing cream can be used if needed.

How much downtime is there after PicoSure? Downtime is generally minimal — mild redness or warmth that settles within hours to a couple of days. Some patients return to normal activities the same day.

How to Know If PicoSure Is Right for You

The safest first step is a consultation, not self-diagnosis from a laser's name. A doctor can assess your pigmentation type — sun spot vs. melasma, surface vs. deep — and confirm whether PicoSure is the right fit or whether another approach would serve you better.
