首尔 Pico Laser 皮秒激光指南

Pico Laser 常被用来讨论色素、肤色不均和部分肤质问题，但并不是每一种情况都适合同样的设置。这个页面先帮您把方向弄清楚。

概述

比起先比较设备型号，先判断自己是色素问题、肤色不均，还是还需要先处理其他项目，会更有帮助。

适用于以下困扰

推荐人群

Immediately post (toning)
Mild redness for 30 minutes to a few hours. No wound for toning settings. Makeup possible the next day.
Immediately post (ablative)
Pin-point microcrusts begin forming on treated lesions (freckles / tattoo); surrounding redness may persist 24-48 hours.
1 week
Microcrusts (ablative) flake off naturally over 5-7 days. Toning sessions show no visible change at this point — cumulative effect develops over the course.
1 month
Initial fade visible on superficial pigmentation (freckles, sun spots). Melasma typically requires multiple sessions before clear improvement.
3 months (mid-course)
Cumulative pigment clearance becomes apparent for melasma protocols. Tattoo pigment continues breaking down between sessions.
6 months
Most pigment-focused programs reach plateau. Maintenance toning every 4-8 weeks supports long-term tone control for melasma-prone skin.

LutronicFDA 510(k) cleared picosecond laser; multiple clearances for benign pigmented lesions and tattoo removal

关键规格

: Picosecond pulse duration (~450 ps) — shorter than the thermal relaxation time of melanosomes
: Energy converts primarily into a photomechanical (photoacoustic) shockwave rather than heat
: Shockwave fractures melanin into sub-micron particles cleared by macrophages, with significantly less collateral thermal injury than nanosecond Q-switched lasers
: Thermal-sparing profile makes it preferred for darker (Fitzpatrick III–V) skin where PIH risk is elevated
Wavelengths: 532 nm (superficial pigment — freckles, lentigines), 1064 nm (Asian-skin-safe melasma toning + dermal pigment), 660 nm and 595 nm (tattoo + ABNOM)
Typical session: 10-15 min for face pigmentation; 20-30 min for tattoo work
: Topical anesthesia not required for standard toning settings
Repeat: 5-10 sessions overall; melasma protocols 4-8 sessions at 2-4 week intervals

01First 24 hours
Toning settings — no special restrictions; avoid hot showers, saunas, vigorous exercise. Ablative settings — apply prescribed soothing balm; do not pick crusts.
02Days 1-7 (ablative only)
Microcrusts flake off naturally over 5-7 days. Do NOT pick or peel — premature removal increases PIH risk. Cleanse gently; broad-spectrum SPF 50+ daily.
03Weeks 2-4
Strict sun protection (SPF 50+, hat, shade). Avoid retinoids and exfoliating acids until full re-epithelialization. Resume normal skincare gradually.
04Long-term (melasma)
Daily SPF, vitamin C / niacinamide topicals, and adherence to maintenance toning every 4-8 weeks if melasma-prone.

Pico Laser 适合所有色素问题吗？

不一定。色素类型不同，治疗方式和预期也会不同，最好先面诊判断。

做完 Pico Laser 后会不会很容易反黑？

是否会出现反应，和皮肤状态、设置方式、术后防晒等都有关系，因此需要先把护理要求讲清楚。

注意 · 禁忌

如有以下情况，请于诊察时告知医师。可能无法进行治疗或需调整方案。

Active skin infection or open wound in the treatment area
Pregnancy or lactation (relative — elective laser deferred)
Recent isotretinoin use within 6 months (relative — increases scarring risk for ablative settings)
Active herpes simplex in the treatment zone (requires antiviral prophylaxis before treatment)
Photosensitizing medication use (review with dermatologist before treatment)
Recent tan or sun exposure within 4 weeks on the treatment area (increased PIH risk)
