Laser Hair Removal Technologies: Diode, Alexandrite, Nd:YAG and IPL Compared — Istanbul
Not every laser suits every skin. Laser hair removal works by heating the pigment in the hair, so the right technology depends on your skin tone and hair colour. In Nişantaşı, our physicians work with three lasers: the diode 810 nm (Alma Soprano Ice), the alexandrite 755 nm (Cynosure, Candela) and the Nd:YAG 1064 nm (Cynosure). This page explains how they differ, why IPL is not a laser, and how we choose the right one for your skin, hair and treatment area.

How Laser Hair Removal Works
Laser light is absorbed by melanin, the pigment in the hair, and turns into heat that damages the follicle. That is why laser works on pigmented (dark) hair and has little or no effect on white, grey, red or very light blonde hair.
The result is permanent hair reduction: fewer hairs grow back, and those that do are finer and lighter. Occasional maintenance sessions, for example once or twice a year, are common.
Three Lasers and IPL at a Glance
Diode 810 nm — Alma Soprano Ice
An in-motion technique: the handpiece glides over the skin with cooling while the heat builds gradually. Comfortable and suitable for most skin types.
Alexandrite 755 nm — Cynosure, Candela
Fast and effective for light to olive skin and finer hair, because its wavelength is strongly absorbed by melanin.
Nd:YAG 1064 nm — Cynosure
Its longer wavelength reaches deeper follicles and is less absorbed by pigment in the skin surface — the safer choice for darker skin.
IPL — not a laser
Intense pulsed light sends a broad range of wavelengths rather than one precise wavelength, so it is less targeted. For hair removal, we use lasers.
Which Laser for Which Skin Type and Hair Colour?
Fitzpatrick skin types run from I (very fair, always burns) to VI (very dark). The table shows the usual first choice, confirmed at your assessment.
| Skin type | Dark hair | Finer or lighter brown hair | Red, blonde, grey or white hair |
|---|---|---|---|
| I–II: very fair to fair | Alexandrite or diode | Alexandrite | Little or no effect |
| III–IV: medium to olive | Diode or alexandrite | Alexandrite or diode | Little or no effect |
| V–VI: brown to very dark | Nd:YAG; diode in selected cases | Nd:YAG or diode, assessed individually | Little or no effect |
With a recent tan or sunburn, the session is postponed, whatever your skin type.
Comfort and Speed
Comfort depends on the laser, the area and the density of the hair. The Soprano Ice in-motion technique with cooling is designed for comfort; the alexandrite is fast. You may feel warmth or a light snapping sensation, and settings are adjusted for you. Approximate session times by area:
- Underarms: about 10 minutes
- Bikini: 15–20 minutes
- Full legs: 45–60 minutes
- Full body: about 1.5–2 hours
Laser Hair Removal Sessions and Intervals
Only hairs in the active growth phase (anagen) respond, and not all hairs are in that phase at once, so several sessions are needed, whichever laser is used.
| Face | Body | |
|---|---|---|
| Typical sessions | 8–10 or more | 6–8 |
| Interval | 4–6 weeks | 6–8 weeks (legs up to 8–10) |
| Maintenance | Common, especially for hormonal hair | Occasional, e.g. once or twice a year |
Hormonal hair, for example with PCOS, may need more sessions and maintenance.
Why We Choose the Laser per Patient
Skin type and tan
We assess your Fitzpatrick type and check for a recent tan or sunburn.
Hair colour and thickness
Dark, coarse hair and finer hair respond differently; each area differs in hair depth and density.
Medical history
Photosensitising medicines, recent isotretinoin, pregnancy, tattoos in the area, keloid tendency, light-triggered epilepsy and hormonal conditions such as PCOS.
Test and settings
A patch test when needed, then settings adjusted to your skin and hair at each session.
Written plan
The laser, areas, number of sessions and intervals are written in your plan.
When Laser Is Postponed
We postpone treatment in the situations below and take extra care with a keloid tendency or light-triggered epilepsy. Redness and swelling are common; blistering, burns and temporary pigment changes are rare, and paradoxical hair growth is very rare.
- Pregnancy
- Sunburn or a recent tan
- Active skin infection or rash
- Photosensitising medication
- Recent isotretinoin
Laser Hair Removal for Visitors
Because sessions are weeks apart, one visit allows one session, so laser suits people who live in Istanbul or visit regularly. You can also start a course here and continue at home: ask us to note which laser was used. For care before and after each session, see our laser care guide.
