Session count

How many pico toning sessions a course usually takes

The short answer

There is no single number. Rewind sets the session count for pico toning after examining your pigment and revises it as the skin responds. For orientation, published low-fluence toning protocols for melasma used five sessions a week apart in one trial and six to ten sessions two weeks apart in another, while discrete freckles may need fewer. Your own count is confirmed at consultation.

The protocol figures on this page come from studies of low-fluence Q-switched lasers for melasma, cited below. They describe research schedules and do not represent a Rewind package or a promised result.

The count depends on three things: which pigment is being treated, how the skin reacts after the first visits, and how much time you can give the course. Melasma sits at the long end because it responds slowly and relapses. Isolated freckles and sun spots usually sit at the shorter end, and marks left after acne vary with how settled the skin is.

What a session count cannot do is buy speed. Adding visits or shortening the gap between them raises the risk of the pale mottling described in the toning literature, so the plan moves at the pace the skin tolerates and is rewritten whenever the skin says so.

What moves the number

Factors that change how many pico toning sessions you need

Two people with similar-looking pigment can end up with very different plans. These are the four variables the doctor weighs.

factor 01
Pigment type
Melasma usually needs the longest plan; discrete freckles and sun spots often need fewer visits.
factor 02
Extent and density
Dense, widespread pigment takes more visits than a handful of scattered marks on clear skin.
factor 03
Skin reaction
Lingering redness, darkening or early pale spots slow the plan down or stop it altogether.
factor 04
Sun and hormones
Ongoing sun exposure and hormonal triggers can erase progress and add visits, especially for melasma.

Ink removal on the same class of laser follows its own session count and spacing and is planned on the tattoo removal page.

Interval

Spacing

How far apart pico toning sessions are spaced

Spacing matters as much as the count. The published protocols give a sense of range; the actual interval at Rewind is set per patient.

01Weekly

One-week gaps in a short, intensive protocol

A split-face melasma trial gave five low-fluence sessions to the whole face at one-week intervals and assessed patients 12 weeks after the last one. By the end of treatment, lightness had improved by 37 percent on the side that received the laser alone.

02Fortnightly

Two-week gaps in a longer course

A study of 34 melasma patients used six to ten sessions, a median of eight, spaced two weeks apart. Severity scores roughly halved by the end of treatment, and 20 patients rated their melasma at least half improved.

03Afterwards

The result is read once the course has ended

Both studies measured outcomes after a gap, and the longer one returned a year later to find recurrence in 20 of 34 patients. A session count is therefore only half a plan; the other half is what happens after the last visit.

04Limit

Why sessions are not simply stacked closer together

Biopsies after a series of low-fluence treatments showed reduced pigment production with melanocytes still present, and the authors warned that repeated low thermal energy may cause long-lasting pale spots. Spacing gives the skin time to settle between visits.

Planning

How Rewind decides your pico toning session plan

The plan starts as an estimate and is corrected at every appointment.

01Draft

A first estimate at consultation

Dr. Jonghwan Choi, a board-certified plastic surgeon, gives an estimated range once the pigment has been identified, based on its type and extent and on the time you have in Seoul.

02Review

Rewritten at every visit

Each session is compared with the one before. If progress is steady, the plan continues; if the skin is reacting, the interval lengthens or the course stops.

03Handover

Planned around your travel

When a full course will not fit into one stay, the doctor plans the visits you can attend here and describes what continuing with a clinician at home would involve.

Every session follows the same pattern, which keeps visits comparable. The skin is cleansed and checked against the last visit, eye protection is fitted, and the Pico K is passed across the field at the settings the doctor has chosen for that day. Redness afterwards is common and settles on its own, and ordinary activities can generally resume the same day.

Sessions can be booked on Monday, Tuesday, Wednesday, Friday or Saturday; the clinic is closed on Thursday and Sunday. Weekday hours run from 10:00 to 19:00 and Saturday hours from 10:00 to 16:00, which helps when several visits have to fit into a short stay.

Rates

Pricing

Pico toning session prices for planning a course

Each session in a toning course is charged at the single-session rate below. The fractional line applies only if a texture treatment joins the plan.

Pico toning, per sessionEvery visit in a toning course is charged at this rate
₩150,000
Pico fraxel, per sessionAdded only when texture work joins the plan
₩300,000

To budget, multiply the session rate by the number of visits you expect to attend in Seoul and add VAT. If part of the course is completed at home, only the Seoul visits appear on Rewind's bill.

Numbing preparation is included in each list rate, and VAT is charged on top at payment.

Fit

Scheduling

Who can complete a pico toning course in Seoul, and who should plan differently

Schedules that tend to work

  • Residents of Seoul, or frequent visitors able to attend repeated sessions
  • Travellers staying several weeks, able to fit more than one visit at the interval the doctor sets
  • Patients returning to Korea on repeat trips across the course
  • Anyone with a clinician at home willing to continue the plan

Schedules that need rethinking

  • A single short stay with the expectation of a complete melasma course
  • A beach or ski trip immediately after the final session
  • A request to shorten the interval so more sessions fit into one trip
  • Skin that showed pale spots or darkening after earlier toning
After

Between sessions

Looking after your skin between pico toning sessions

The time between sessions is when fragmented pigment clears and the skin settles. Rewind's laser aftercare instructions apply after every visit in the course.

After each visit
Redness possible
Redness straight after the laser is expected on the clinic's sheet and fades by itself.
Same day
No sauna or sweaty exercise
Heat and heavy sweating are kept away from freshly treated skin.
Next days
No massage or harsh rubbing
The treated area is left unstimulated while it recovers.
Throughout the course
Sunscreen outdoors
Sun protection between sessions decides whether each visit builds on the last or has to make up lost ground.

Report redness that lasts beyond the day, darkening, pale spots or blistering before your next booked session, since the doctor may change the interval or stop the course. A 2015 report examining melanin and melanocytes in mottled pale spots after toning is listed in the references for anyone who wants the detail.

Questions

Pico toning sessions: count, spacing and travel

How many sessions does a pico toning course take to show results?
That varies with the pigment and with how your skin handles the first visits, so the doctor gives a range at consultation and narrows it as you go. Research protocols for melasma ran from five treatments to ten; isolated freckles and sun spots often settle with fewer. Improvement accumulates visit by visit.
How far apart should pico toning sessions be?
The interval is set by the doctor for your skin. Published low-fluence melasma protocols spaced sessions one week apart in one trial and two weeks apart in another. Sessions are spaced further apart if the skin reacts, because packing them closer raises the risk of pale mottling.
Can I do pico toning in one trip to Korea?
A complete course rarely fits one short trip, since toning is repeated over weeks. A longer stay can accommodate several visits at the interval the doctor sets. Otherwise, start in Seoul and continue at home or on later trips, with daily sun protection holding the gains in between.
Will I see a difference after the first session?
Sometimes a slight change, but toning is designed to work cumulatively, and the first visit mainly shows how your skin reacts. That reaction guides the settings and interval for the rest of the course, and progress is judged against the clinic's record at later visits.
What happens if a session is missed or the gap gets longer?
A longer gap generally carries less risk than a shorter one; the course resumes when you return, after the doctor reassesses the skin. Unprotected sun during the gap matters more than its length, because it can re-darken pigment that has already lightened.
Do I need maintenance sessions after the course?
For melasma, often yes. One study found recurrence in 20 of 34 patients a year after low-fluence treatment ended. Whether and when to book a maintenance visit is decided on your skin at review. Freckles also return with sun, so protection matters for every pigment type.
Why can't sessions be done closer together to finish faster?
Repeated low-energy exposure is itself the risk. Researchers have linked frequent low-fluence toning to scattered pale spots, with biopsies showing reduced pigment production. Spacing lets the skin recover, and the doctor lengthens the gaps at the first sign of uneven lightening.
Is the session count different for brown marks left by acne?
Flat brown marks after acne are planned like other toning courses, but treatment only starts once breakouts have calmed. Fresh breakouts can leave fresh marks, which lengthens the plan, so the doctor sets the count after checking how settled the skin is and revisits it at each visit.

Scientific evidence

Session counts and intervals in low-fluence toning studies

The session numbers and intervals quoted on this page come from the first two studies, both of melasma treated with low-fluence Q-switched lasers, the method picosecond toning builds on. The other two examine what repeated sessions can do to pigment cells and why spacing matters. None was carried out at Rewind Plastic Surgery, and none sets the number of sessions your own skin will need.
