This is a procedure note for PICO Toning and Laser Toning: Why Multiple Sessions Are Needed at Beomgye(Opening Soon) KKEUT Korean Clinic.
Why Picohigh Toning and Laser Toning Both Require Multiple Sessions?
Those exploring Picohigh Toning for the first time often ask one question.
'Can't it disappear all at once?'
To put it simply, both Picohigh Toning and Laser Toning require multiple cumulative sessions for noticeable results.
The reason lies not in the treatment method, but in the structure of the pigment itself.

Laser Toning vs. Picohigh Toning: What's the Difference?
Laser Toning involves irradiating the skin with a 1064nm wavelength laser to selectively destroy melanin pigment.
It primarily targets areas with excessive melanin accumulation, such as melasma, freckles, and hyperpigmentation.
Picohigh Toning emits energy in 'picosecond' (one trillionth of a second) units, which is much shorter than conventional nanosecond lasers.
Because high energy is concentrated in a short period, it can break down even finer pigment particles.
If the nanosecond method breaks large stones, the picosecond method is like breaking those fragments into even smaller pieces.

Why One Session Isn't Enough
Melasma and hyperpigmentation involve melanin dispersed throughout various parts of the skin's epidermis.
While a laser destroys melanin at the irradiated spot in one session, it cannot remove all latent pigment beneath the skin simultaneously.
The destroyed melanin fragments are absorbed by immune cells and expelled from the body, a process that itself takes several weeks.
After one session, the skin enters a new regeneration cycle, and subsequent sessions aim to remove pigment from deeper layers.
For pigmentation to completely lighten, this process must be repeated multiple times; neither Picohigh Toning nor Laser Toning is an exception to this principle.

Generally Recommended Number of Sessions and Frequency
For improving melasma and freckles, a minimum of 10 cumulative Laser Toning sessions is recommended.
The frequency is typically every two weeks, and the key is to receive consistent treatments without overdoing it, in sync with the skin's regeneration cycle.
While Picohigh Toning tends to require fewer sessions due to its higher destruction efficiency, the exact number of sessions needed varies depending on skin condition and pigment depth.
Initial sessions might not show significant visible changes, leading to doubts, but as sessions accumulate, changes such as more even skin tone and lighter pigmentation gradually become apparent.

Why Sun Protection is Crucial During Laser Toning
Even if pigmentation is reduced through treatment, continued UV exposure can reactivate melanocytes, leading to pigment regeneration.
During Picohigh Toning, sunscreen use is not an option but a necessity.
Applying SPF50+ sunscreen daily and reapplying every 2-3 hours during outdoor activities is the most crucial post-treatment care for maintaining results.
Washing your face and applying makeup are generally possible on the day of the procedure, but it's best to avoid irritating acidic toners or retinol products for at least 2-3 days.

Kkeut Clinic's Unique Differentiators for Laser Toning & Picohigh Toning
Even with the same toning treatment, the results vary depending on how it is performed.
Kkeut Clinic guarantees over 2000 shots for toning treatments, including Picohigh Toning.
After the treatment, we have a procedure where you can personally verify the shot count with the director.
The shot count is directly linked to effectiveness. Treatments with fewer shots that finish quickly may seem cheaper, but often necessitate additional sessions.

At Kkeut Clinic, we focus on intensely targeting areas where an individual's pigmentation is particularly dense or a concern is deeply rooted.
Instead of evenly treating the entire forehead, we concentrate more energy on areas where melanin is densely packed, such as the cheekbones, around the nose, and under the eyes.
While some places maintain the same energy level for each session, Kkeut Clinic applies a protocol of slightly increasing energy in each subsequent session.
This approach considers the skin's adaptation to stimulation, progressively targeting deeper pigment layers.

Frequently Asked Questions
Q. Which should I choose, Picohigh Toning or Laser Toning?
A. Picohigh Toning is suitable for those who have experienced slow results with conventional Laser Toning or those with relatively deep-seated pigmentation, as it breaks down pigment particles more finely. The exact treatment best suited for you should be determined after a thorough skin assessment.
Q. How many Picohigh Toning sessions are needed to feel the effects?
A. Pico High Toning varies depending on individual skin condition and pigment depth, but typically, skin tone equalization and pigment reduction become visible after the 5th session. Kkeut Clinic gradually increases the energy with each session to accumulate effects.
Q. Can pigmentation temporarily darken during laser toning?
A. Yes, it can happen. As the destroyed melanin rises to the surface of the epidermis, it may temporarily appear darker. This is a normal reaction as the pigment is expelled, and the skin will become clearer as subsequent sessions progress.
Q. What should I do if UV exposure is unavoidable during Pico High Toning treatment?
A. If you have outdoor activities during your Pico High Toning period, it is essential to use SPF50+ sunscreen and block direct UV rays with a hat or parasol. Neglecting UV protection can reduce the treatment's effectiveness by more than half.

The Sincerity of Kkeut Clinic
Kkeut Clinic guarantees over 2000 shots for all toning treatments, including Pico High Toning, and operates a transparent process where patients can directly confirm the shot count with the director after the treatment.
Instead of uniformly targeting the entire forehead, Kkeut Clinic focuses on problem areas with concentrated pigmentation, such as the cheekbones, around the nose, and under the eyes, pursuing more efficient results in the same session.
Kkeut Clinic applies a protocol that gradually increases the energy with each session instead of maintaining it uniformly, treating with a differentiated approach that progressively targets even deeper pigment layers.
