Picosecond Laser Information
Picosecond laser is a type of laser treatment that acts on the skin with extremely short pulse durations. Different models and handpieces are used for various conditions. Medical laser devices are regulated medical devices that must be approved by the Taiwan Food and Drug Administration (TFDA); treatments are medical procedures that must be performed by qualified physicians. The following is neutral information without efficacy claims.
Mechanism of picosecond laser and different handpieces
The characteristic of picosecond laser is its extremely short pulse duration (picosecond level). Compared to traditional nanosecond lasers, it acts more via photoacoustic effects. Depending on the handpiece or lens used, the mechanism differs, and the physician selects based on skin condition.
- Standard flat handpiece: commonly used for pigmentation-related conditions
- Focused lens handpiece (e.g., honeycomb, fractional): commonly used for skin texture-related conditions
- Different wavelengths (e.g., 532nm, 1064nm) target different depths and pigments
General concept of treatment sessions and recovery
Picosecond laser is often planned in multiple sessions, with intervals determined by the physician based on skin condition. Different handpieces and energy settings result in varying post-treatment reactions and recovery concepts; some may involve temporary redness or mild crusting. Actual number of sessions, intervals, and care should be assessed by a physician. Results vary by individual. This site makes no efficacy claims.
Frequently Asked Questions
What is the difference between picosecond laser and regular laser?
The main difference is the pulse duration (picosecond laser uses extremely short pulses). Different models and handpieces are suitable for different conditions. Suitability should be assessed by a physician based on skin condition.
Are picosecond laser devices regulated?
Yes. Medical laser devices are regulated medical devices that must be approved by the TFDA before use; treatments must be performed by qualified physicians in licensed medical facilities. You can inquire about the device model and approval information at the clinic.
How is the cost of picosecond laser calculated?
It is usually priced per number of shots or per session, depending on the device and treatment area. It is an out-of-pocket expense not covered by health insurance. Actual pricing should be confirmed with the clinic in writing.
What should be noted after picosecond laser treatment?
Generally, it is recommended to enhance sun protection and moisturizing, and follow the physician's instructions for care. Recovery varies by individual. Please follow the physician's specific instructions.
Can post-inflammatory hyperpigmentation (PIH) occur after laser treatment?
Some individuals may experience temporary PIH (commonly referred to as 'rebound darkening') after laser or other light-based treatments. This is related to skin type, energy settings, and post-treatment sun protection. It usually changes over time, with significant individual variation. Enhanced sun protection and following the physician's care instructions can help reduce risk. Actual conditions should be assessed by a physician.

Can picosecond laser make skin whiter or completely remove spots in one session? How many sessions are typically needed?
Generally, it is unlikely to "completely remove spots in one session." Picosecond laser treatments usually require multiple sessions depending on spot type, depth, and skin condition; the number and interval vary by individual and must be assessed by a physician. Additionally, "whitening" and "spot removal" are different concepts—laser targets specific pigmentation issues, not overall skin bleaching. Some spots (especially melasma) may recur, requiring daily sun protection and care to reduce recurrence or post-inflammatory hyperpigmentation. The actual number of sessions, suitability, and expected outcomes should be based on an in-person consultation with a physician.
