(01)AT A GLANCE
The treatment's role
The ruby laser treats pigment using a 694 nm wavelength absorbed by melanin. Diagnosis determines suitability and the treatment area.
Suitability, methods, and expected changes vary by person.(02)YOUR CONCERN
From the small changes you notice,
a consultation begins.
- 01
When distinct dark spots remain
- 02
When deeper pigmentation needs diagnosis
- 03
When pigment did not respond well to previous treatment
DIAGNOSIS BEFORE LIGHT
Whether treatment is needed is decided after consultation.
(03)UNDERSTANDING
Superficial and deeper pigment may need different approaches. We assess the lesion alongside its response to previous treatment.

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.
(04)THE DAYONE APPROACH
Areas, coverage, and combinations with other treatments
are reviewed with your doctor for your current condition.

(06)BEFORE YOU DECIDE
Specific explanations about your condition and plan
continue in consultation with your doctor.
01Will switching lasers remove all remaining pigment?+
Changing devices alone cannot guarantee results. We reassess the remaining pigment and your skin's response, and explain the goals and limits of treatment.
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.
