Why it is called fractional
为什么叫「点阵」
Older resurfacing lasers removed the entire surface layer of skin across the treatment area. Effective, but the recovery was weeks and the risks were significant.
早期的剥脱激光会把治疗区域的整层表皮全部去除。效果确实好，但恢复期以周计，风险也高。
Fractional technology divides the beam into a grid of tiny columns. Each column of skin is treated to depth, but healthy untreated skin is left in between. Those untreated bridges are what drive rapid healing — the surrounding intact tissue supplies the repair. That is the entire reason recovery dropped from weeks to days.
点阵技术把光束分成网格状的微小柱阵。每一个柱状区域被深度处理，但柱与柱之间保留完好的皮肤。这些未被处理的「桥梁」是快速愈合的关键——周围完整的组织为修复提供支持。这就是恢复期从数周缩短到数天的原因。
How it addresses a scar
它如何作用于疤痕
An indented acne scar is a place where the skin healed with less tissue than it started with. The surrounding skin sits at normal height and the scar sits below it.
凹陷型痘疤是皮肤在愈合时组织量少于原本的位置。周围皮肤在正常高度，疤痕陷在下方。
The laser does two things. It removes a controlled amount of tissue at the edges of the scar, softening the sharp shoulder that makes an indentation catch the light and look deeper than it is. And the thermal effect below stimulates new collagen to build the base of the scar upwards over the following months.
激光做两件事。一是可控地去除疤痕边缘的部分组织，柔化那道让凹陷「卡光」、显得比实际更深的锐利边缘。二是下方的热作用刺激新生胶原，在接下来数月里把疤痕的底部逐步垫高。
This is why results keep improving for three to six months after the skin has healed. The visible recovery is over in a week; the actual remodelling takes far longer.
这就是为什么皮肤表面愈合之后，效果还会持续改善三到六个月。可见的恢复一周结束，真正的重塑要长得多。
The recovery week, honestly
恢复的那一周，如实说
| Day | What to expect | 天数 | 会发生什么 |
|---|---|---|---|
| 1–2 | Hot, red, swollen. Similar to strong sunburn. Swelling is often worst on waking day two. | 1–2 | 发烫、泛红、肿胀，类似严重晒伤。第二天早上起床时肿胀通常最明显。 |
| 3–5 | A fine bronzed, gritty texture develops. This is the treated tissue moving out. Do not pick it. | 3–5 | 出现细密的古铜色粗糙质感，是处理过的组织在向外代谢。不要抠。 |
| 5–7 | Flaking clears to reveal pink new skin. Makeup is usually fine from around here. | 5–7 | 脱屑完成，露出粉红色新生皮肤。大约从这时起可以上妆。 |
| Weeks 2–6 | Pinkness fades gradually. Sun protection is non-negotiable through this phase. | 第 2–6 周 | 粉红逐渐消退。这个阶段防晒没有商量余地。 |
The one rule that matters most: do not pick, scrub or exfoliate while the skin is flaking. Interfering with that layer before it is ready is the main cause of prolonged redness and, in some cases, new marks. Let it come away on its own.
最重要的一条：脱屑期间不要抠、不要搓、不要去角质。在皮肤准备好之前干预这一层，是持续泛红——某些情况下甚至留下新痕迹——的主要原因。让它自己脱落。
Which scars respond, which don't
哪些疤痕有效，哪些没有
- Rolling scars — shallow, wide, wave-like indentations. These respond well.
- 滚动型——浅而宽、波浪状的凹陷。反应良好。
- Boxcar scars — round or oval with defined edges. Respond well, particularly the shallower ones.
- 箱车型——圆形或椭圆形、边缘清晰。反应良好，较浅的尤其明显。
- Ice-pick scars — narrow and deep, like a puncture. Limited response to laser alone; usually need a combined approach.
- 冰锥型——窄而深，像针刺。单靠激光效果有限，通常需要联合方案。
- Raised or keloid scars — a different condition. Resurfacing can make these worse and they need separate assessment.
- 增生型或疤痕疙瘩——完全不同的情况。剥脱治疗可能使其加重，需要单独评估。
Before you book
预约之前
Active acne needs to be under control first — treating skin that is still breaking out risks spreading inflammation and creating new marks. Recent isotretinoin use also affects timing, and any history of cold sores should be mentioned, as resurfacing can trigger an outbreak that is worth preventing in advance.
活动期的痘痘需要先控制住——在还在长痘的皮肤上做，有扩散炎症和产生新痕迹的风险。近期使用过异维 A 酸也会影响时间安排。如果有唇疱疹病史一定要说明，剥脱治疗可能诱发复发，这是可以提前预防的。
