What a pico laser actually does
Pico lasers deliver energy in pulses measured in picoseconds, which are trillionths of a second. Older Q-switched lasers work in nanoseconds. The shorter pulse is designed to break pigment into very fine particles with a mostly mechanical, "shattering" effect rather than relying heavily on heat. Your body then clears those particles gradually over the following weeks.
Because less heat spreads into the surrounding skin, pico lasers are often chosen in Korea for low-energy "toning" across the whole face. Toning means many gentle passes rather than one aggressive treatment. This approach is popular for skin types that tend to darken after irritation, but it is a tool and not a cure-all. Which pigment you have matters more than which laser brand is used.
Pigmentation concerns pico lasers are commonly used for
Doctors in Korea commonly use pico lasers, either as gentle toning or as targeted spot treatment, for the following concerns:
- Sun spots (solar lentigines).
Flat brown spots on the cheeks, temples and hands that build up with sun exposure. These are distinct spots of pigment and often respond to targeted pulses.
- Freckles.
Small, scattered spots that darken in summer. They may lighten with treatment but can come back with sun exposure, so sun protection is part of the plan.
- Uneven, dull tone.
General blotchiness or a "tired" look from mild pigment spread across the face. Low-energy toning is often used here.
- Post-inflammatory hyperpigmentation (PIH).
Brown marks left after acne or irritation. Gentle toning may help them fade faster than they would on their own, though many fade slowly anyway.
- Melasma, as part of a wider plan.
Melasma is hormonal and sensitive to heat and irritation. Low-energy toning is sometimes included, but it is managed rather than "removed", and other measures matter just as much.
- Deeper pigment such as Hori's nevus or nevus of Ota.
These lie deeper in the skin and usually need a doctor's diagnosis and a longer course. Whether a pico laser is appropriate is decided case by case.
Concerns a pico laser may not be the right answer for
Not every dark or discoloured patch is pigment that a laser should target. A doctor should look first, because some lesions need a different approach or a medical check:
- Redness and broken capillaries.
These are vascular, not pigment. Different settings or devices are used, so see our page on facial redness treatment.
- Raised spots and moles.
Raised growths such as seborrheic keratoses, or moles that are changing, should be assessed by a doctor before anything is lasered.
- Dark circles from shadowing or thin skin.
If the darkness comes from volume loss or visible vessels, toning on its own may change very little.
- Active inflammation.
Irritated or sunburnt skin is usually treated after it settles, because laser energy on inflamed skin can make pigment worse.
Pico toning at Daybeau Clinic Seomyeon
At Daybeau Clinic Seomyeon, the pico option on the price list is Pico Light Black Toning at KRW 29,000. That is the first-visit price, VAT excluded (10% VAT is added at payment), checked October 2026. The first-visit price applies once per new patient per item. You can see the full list on our price list, and more detail on the treatment itself on our pico toning page.
The doctor first checks what type of pigment you have and how sensitive your skin is, then confirms whether toning makes sense and how often. Payment is made at the clinic on the day, after the consultation confirms the plan. If the doctor thinks another approach would suit you better, such as combining toning with home care or treating redness first, they will explain why.
What to expect during and after treatment
Low-energy toning usually feels like quick snapping or warm prickling. Many people find it tolerable without numbing cream. Typical short-term effects include:
- Mild redness or warmth.
This usually settles within hours.
- Slight darkening of spots.
Targeted spots can briefly look darker or form fine crusts before they fade. This is more common with spot treatment than with toning.
- Dryness.
A simple moisturiser and gentle cleanser help.
Less common risks include rebound darkening, patchy lightening, or irritation, particularly if the skin is overtreated or exposed to strong sun afterwards. This is why settings are adjusted for your skin and why sunscreen is not optional. Results vary from person to person, and most pigment concerns need a series of sessions rather than a single visit.
Frequently asked questions
Can a pico laser permanently remove pigmentation?
Some spots, such as individual sun spots, may clear and stay clear with good sun protection. Others, especially melasma and freckles, tend to return with sun or hormonal triggers, so maintenance is often needed. Results vary and are never guaranteed.
Is pico toning safe for darker skin tones?
Low-energy toning is often chosen for skin that tends to darken after irritation, but every skin type carries some risk of pigment change. The doctor adjusts settings after examining your skin and may recommend a test approach first.
Can I have pico toning while pregnant?
Please tell the doctor if you are pregnant or breastfeeding. Many clinics postpone elective laser treatment during pregnancy, and melasma often changes after pregnancy anyway, so this is a conversation to have with a doctor.
Do I need to stay out of the sun afterwards?
You do not need to stay indoors, but daily sunscreen, reapplication and shade are important for the weeks after treatment, as UV exposure can undo progress or trigger new pigment.
