(01)AT A GLANCE
The treatment's role
Pico toning uses short picosecond laser pulses to break pigment into small particles. DAYONE uses PicoWay and selects the wavelength and treatment method according to the type of lesion, such as melasma or dark spots.
Suitability, methods, and expected changes vary by person.(02)YOUR CONCERN

DIAGNOSIS BEFORE LIGHT
Whether treatment is needed is decided after consultation.
(03)UNDERSTANDING
Not all dark-looking skin has the same pigment cause. Distribution, depth, and responses to previous treatment guide the approach.

Pigment distribution
We first assess where and when changes began and their distribution.
We check where and when changes began.

Causes of redness
We distinguish the causes of pigment and redness instead of treating them as one problem.
The lesion type guides the method and coverage.

Previous treatment response
We review previous treatments and reactions before considering the next plan.
We adjust the next plan after reviewing skin reactions.

(06)BEFORE YOU DECIDE
Specific explanations about your condition and plan
continue in consultation with your doctor.
01Are melasma and spots treated at the same intensity?+
Similar-looking lesions may differ in type and depth. Diagnosis guides the method and follow-up interval instead of one intensity for everything.
02How much pain or discomfort should I expect?+
Pain and discomfort vary with method, area, and intensity. Check pain-control options and expected discomfort beforehand, and share previous sensitivity reactions.
03How should I plan recovery and daily activities?+
Recovery varies with pigment type and irradiation method. Color changes or flaking may occur; sun protection, hydration, and avoiding irritation are important. Follow your individual guidance first.
04How long do results last?+
Duration varies with method, area, skin condition and treatment history. This page alone cannot predict a fixed duration; your doctor will explain goals and follow-up timing at consultation.
05How are session count and intervals decided?+
The same count or interval is not set for everyone at the outset. Your doctor explains your goals and plan at the first visit, and the next session is timed after reviewing recovery and progress.
06Can I combine this with other treatments?+
We prioritize pigment, vascular redness, and texture separately. Instead of using every device on the same day, we plan the order around skin response and recovery.
