How IPL targets hair
IPL 如何作用于毛发
IPL releases broad-spectrum light that is absorbed by melanin — the pigment that makes hair dark. The absorbed light converts to heat, which travels down the hair shaft to the follicle and damages the structures responsible for producing new hair.
IPL 释放宽光谱光，被黑色素——也就是让毛发呈现深色的色素——吸收。吸收的光转化为热，沿着毛干传导到毛囊，破坏负责生成新毛发的结构。
Two things follow from this. First, the hair must be darker than the surrounding skin for the energy to go where it should. Second, the follicle must be in its active growth phase — a follicle that is dormant has no connection to the hair shaft and will not receive the heat.
由此产生两个结果。第一，毛发必须比周围皮肤深，能量才会去到该去的地方。第二，毛囊必须处于活跃生长期——休止期的毛囊与毛干没有连接，接收不到热能。
At any moment only a portion of your follicles are in that active phase. That is the entire reason a course of sessions is required rather than one visit.
任何时刻只有一部分毛囊处于活跃期。这就是为什么需要一个疗程而不是一次就够。
Waxing — what it does
蜡脱 — 它做了什么
Waxing removes hair from the root mechanically. Regrowth takes several weeks rather than days, and the new hair often comes back with a tapered tip rather than the blunt end left by shaving, so it feels softer.
蜡脱通过机械方式把毛发连根拔除。重新长出来需要数周而非数天，新长的毛通常是尖端而非刮毛留下的钝头，所以摸起来更柔软。
It works on any hair colour, which is its main advantage over IPL. It costs less per session but continues indefinitely.
它对任何颜色的毛发都有效，这是相对 IPL 的主要优势。单次成本较低，但需要无限期持续。

直接对比
| IPL | Waxing | IPL | 蜡脱 | ||
|---|---|---|---|---|---|
| Works on | Dark hair only | Any hair colour | 适用毛发 | 仅限深色 | 任何颜色 |
| Result | Long-term reduction | Smooth for weeks | 效果 | 长期减量 | 数周光滑 |
| Commitment | Course of sessions | Ongoing, indefinitely | 投入方式 | 一个疗程 | 长期持续 |
| Between visits | Shave only | Grow out before next | 间隔期间 | 只能刮 | 需留长再做 |
| Ingrown hairs | Usually reduce over time | Can occur | 内生毛 | 通常随时间减少 | 可能发生 |
The honest cost comparison: IPL costs more upfront and less over years. Waxing costs less each time and never stops. Which is better value depends entirely on how long you intend to keep doing it — and on whether your hair colour makes IPL viable at all.
诚实的成本对比：IPL 前期投入高、长期摊薄后低。蜡脱每次便宜，但永远不会结束。哪个更划算完全取决于你打算做多久——以及你的毛发颜色是否让 IPL 可行。
Before an IPL course
开始 IPL 疗程之前
- Stop waxing and plucking about four weeks before starting. The root needs to be present.
- 开始前约四周停止蜡脱和拔毛。毛根必须存在。
- Avoid sun exposure and fake tan on the area. Tanned skin absorbs more energy and raises the risk of burns.
- 治疗部位避免日晒和使用美黑产品。晒黑的皮肤吸收更多能量，灼伤风险上升。
- Shave the area the day before, unless advised otherwise. Surface hair burns rather than conducting energy usefully.
- 除非另有说明，前一天把治疗部位刮干净。留在表面的毛只会被烧焦，不能有效传导能量。
- Mention any photosensitising medication. Some antibiotics and skincare actives change how skin responds to light.
- 告知任何光敏性药物。部分抗生素和护肤活性成分会改变皮肤对光的反应。
