Both pico toning and Q-switched laser toning are gentle, low-energy lasers used across the whole face for pigmentation. Here is how they differ and how to choose on a trip to Seoul.
Pico toning and traditional laser toning both pass a low-energy laser over the whole face to break down pigment gradually with little or no downtime. Pico toning uses picosecond pulses that shatter pigment with more mechanical, less heat-based energy, while traditional toning uses a nanosecond Q-switched Nd:YAG laser. Both suit melasma, dullness and uneven tone, usually over 5–10 sessions. At Dernia Clinic Myeongdong in Seoul, pico toning starts from ₩69,000 and laser toning from ₩49,000 per full-face session (KRW, excluding 10% VAT).
Prices are in Korean won, exclude 10% VAT and are confirmed by a doctor at consultation.
Pico toning vs laser toning: the short answer
Both are excellent, gentle options for pigmentation, and neither is universally better. Pico toning uses extremely short picosecond pulses that break pigment into finer particles with less heat, which many doctors prefer for stubborn pigment and heat-sensitive skin. Traditional laser toning uses a nanosecond Q-switched Nd:YAG laser that has been a Korean standard for melasma and dull tone for many years and costs a little less per session.
Your doctor's choice depends on your pigment type, how your skin reacts to heat, your budget and how many sessions you can fit into your stay.
Why toning is so popular in Korea
Toning became a staple of Korean dermatology because it fits the local preference for gradual, low-risk improvement. Instead of one strong treatment that leaves the skin raw, toning delivers small, repeated doses of energy that brighten skin over weeks. People often book it on a lunch break and go straight back to work. For visitors, that same low downtime makes it easy to fit around sightseeing and shopping.
The trade-off is patience. Toning rarely produces a dramatic change after one session, and pigment such as melasma can return if the skin is exposed to strong sun or heat. Think of toning as a course and a maintenance habit rather than a one-off fix. Many people combine it with good sunscreen, gentle skincare and, where appropriate, topical treatments recommended by the doctor.
Pico vs Q-switched: why pulse length matters
The main technical difference is how long each laser pulse lasts. A nanosecond Q-switched pulse is short, but a picosecond pulse is about a thousand times shorter. Shorter pulses break pigment with more of a pressure effect and less heat spreading into surrounding skin. In practice, this can mean pigment breaks into finer particles that the body clears more easily, and the skin may feel less heat during treatment. That does not make Q-switched toning outdated; it remains effective, well understood and more affordable per session.
What is laser toning?
Traditional laser toning uses a low-fluence Q-switched Nd:YAG laser at 1064 nm, passed evenly across the whole face. Each session delivers gentle energy that breaks down excess pigment a little at a time without injuring the surface. Because it is mild, it is repeated over a series of sessions, which is why it has long been popular for melasma, dullness and oily, large-pored skin.
See the laser toning page for details.
What is pico toning?
Pico toning uses a picosecond laser, which fires pulses measured in trillionths of a second. These ultra-short pulses create a photomechanical effect that shatters pigment into very small particles, which the body then clears. Because less energy is converted into heat, pico toning can be gentler on skin that tends to react to heat, while still being effective on pigment.

Which pigmentation types respond best?
Not all brown spots are the same. The pigment type affects which laser your doctor chooses and how many sessions you need.
- Melasma: hormonal, patchy pigment on the cheeks, forehead and upper lip. Both toning methods are used gently and repeatedly; aggressive treatment can make melasma worse. See melasma.
- Freckles and sun spots: more defined spots. Pico toning, or spot treatment with a higher-energy setting, is often more efficient.
- Dullness and uneven tone: both work well over a series.
- Post-inflammatory marks: brown marks after acne often respond to gentle toning, though they also fade with time and sun protection.

Who is a good candidate?
Usually a good fit
- Melasma or patchy pigment you want to treat gently
- Dull, uneven tone with no tolerance for downtime
- Skin that reacts to heat (often pico toning)
- Visitors staying long enough for several sessions
Talk to the doctor first
- A fresh tan or recent strong sun exposure
- Active eczema, infection or broken skin
- Use of photosensitizing medicines or recent isotretinoin
- Pregnancy, if you are considering treatment for melasma
What happens on treatment day
- English consultation. A licensed doctor examines your pigment, often with magnification, and recommends a laser and number of sessions.
- Cleansing. Makeup and sunscreen are removed.
- Eye protection. You wear protective goggles throughout.
- Toning. The laser is passed evenly over the face. You feel light snapping or warmth.
- Soothing. A calming mask or LDM can be added, and sunscreen is applied before you leave.
How many sessions do you need?
Most people see brighter, more even skin after a few sessions, with a clearer change after five to ten. Melasma needs patience and maintenance, because it can return with sun exposure, heat and hormonal changes. Sessions are usually one to two weeks apart, so a two-week trip may fit two or three sessions. See how many pico toning sessions you need.
Is it safe? Risks and side effects
Toning is among the gentlest laser treatments, but it is still a medical procedure.
- Common: mild redness or warmth for a few hours.
- Uncommon: small pinpoint marks or temporary darkening of some spots.
- Rare: rebound hyperpigmentation or, with overly frequent or high-energy treatment, patchy lightening (mottled hypopigmentation). Conservative settings and sensible intervals reduce this risk.
Strict daily sun protection is essential. Read sun protection after pico toning.

Planning toning around your Seoul trip
- Book ahead. Send your dates through our consultation form so we can space sessions across your stay.
- Avoid your arrival day. Start on day two, then repeat one to two weeks later if you are staying longer.
- Protect from sun. Sightseeing in Seoul means a lot of daylight; reapply sunscreen and wear a hat.
- Getting here. Dernia is near Myeongdong Station (Line 4) and Euljiro 1-ga Station (Line 2).
Flying home? Toning has no wounds, so you can usually fly the next day. Keep skin hydrated on the plane and use sunscreen at your window seat. See laser before a flight.
Frequently asked questions
Is pico toning better than laser toning for melasma?
Both can help melasma when used gently over a series. Pico toning delivers less heat, which some doctors prefer for heat-sensitive or stubborn pigment.
How many toning sessions do I need?
Most people need 5–10 sessions, one to two weeks apart, followed by maintenance for melasma.
Is there downtime after pico toning?
Usually none, or mild redness for a few hours. You can wear makeup the next day in most cases.
Can toning make pigmentation worse?
Rarely, if settings are too strong or sessions too frequent. Conservative treatment and strict sun protection reduce the risk.
Can I have toning with a tan?
Usually not. A fresh tan raises the risk of side effects, so your doctor may delay treatment.
