How do lasers work in hair removal?

Laser hair removal is based on science and advanced precision technology. Find out how it works here:

1. the science behind it

Think of a laser as a single-color spotlight that focuses on the pigment of the hair.
It emits this focused light at a specific wavelength that directly targets the melanin in the hair.
This light is absorbed by melanin, a natural pigment in the body that gives hair and skin their color.
The absorbed light energy is converted into heat in the hair follicle.
This heat damages the follicle so that it can no longer produce new hair.

As the laser light is mainly absorbed by melanin, it is aimed specifically at the hair and not the surrounding skin.

2. why hair growth phases are important

Not all hairs are treated at the same time - only those in the active growth phase (anagen phase):

Anagen phase (growth)

The hair is actively connected to the root. In this phase, the laser can destroy the follicle because it targets the melanin in the hair.

Catagen phase (transition)

The hair detaches from the root → laser effect is minimal.

Telogen phase (rest)

The hair soon falls out → Laser has no effect.

As only 20-30 % of hair is in the anagen phase at any one time, several sessions over several months are required for optimal results.
Clients usually plan about one session per growth cycle (every four to six weeks) to effectively treat all hair as soon as it reaches the anagen phase.

3. why different lasers have different wavelengths

Lasers are designed with specific wavelengths - measured in nanometers (nm), a unit of measurement that determines how deep the light can penetrate the skin.

808-810 nm (diode laser): Gold standard → works for most skin and hair types.
1064 nm (Nd:YAG): deepest penetration, safe for dark skin.

👉 These wavelengths are in the near infrared range, which is safe for the skin and ideal for follicle targeting.

4. cooling systems - safety first

Modern medical lasers are equipped with cooling systems:

They keep the skin surface pleasantly cool.

They reduce redness and irritation.

They make the treatment virtually painless.

Many people ask about the difference between IPL and real lasers.
Here's what makes them different:

Many studios advertise with IPL (Intense Pulsed Light)as if it were laser hair removal. But IPL is not a real laser.
Imagine a flashlight that scatters light in all directions - and now a laser pointer that hits a single point.
IPL uses broadband light (many different wavelengths), which is less targeted.
This can lead to more irritation and less effective long-term results.

Laser: uses a single wavelength for targeted, safe and effective long-lasting results.

With Skinlaser Lucy we only use NiSV-certified diode laser technology - never IPL.

🌟 Customer experiences

⭐ Lea, 29 - Legs
Lea spent 20 minutes a day shaving her legs - a time-consuming routine.
"I was nervous before my first treatment, but Lucy explained exactly how the laser works.
The cooling made it pleasant - I only felt a warm tingling sensation. After four sessions, shaving is hardly necessary."

⭐ Markus, 41 - Chest
"I found it impressive how Lucy showed that the laser only targets the hair follicle and not the surrounding skin.
After two sessions, visible gaps appeared on my chest.
She also explained the difference between laser and IPL - that helped me to make the right decision."

⭐ Sandra, 35 - Armpits
"I had previously tried waxing and IPL treatments, but the results didn't last.
With Lucy's diode laser, I noticed smoother skin after just a few weeks. After seven sessions, my armpits are hair-free and irritation-free."

⭐ Daniel, 38 - Back
"My main concern was safety as I have slightly darker skin. Lucy carefully adjusted the settings,
and the cooling system kept the temperature comfortable. No burns or redness - just smooth results."

Frequently asked questions - How lasers work

Is laser hair removal safe for the skin?

Yes, if it is carried out with certified technology and by trained specialists.
The laser only targets the follicle, not the surrounding tissue.
Studies show that less than 0.1 % of treatments result in persistent redness.

Can very light or gray hair be treated?

Lasers work best on dark hair with a high melanin content.
Very light, red or gray hair is less responsive because there is almost no melanin.

What is the difference between laser and IPL?

IPL uses broadly scattered light, while laser uses a single precise wavelength.
IPL is less effective and not permanent.

Can I have the laser treatment in summer?

Yes - avoid direct sun before and after sessions and use sunscreen on treated areas.

Are there any side effects?

Temporary redness or slight swelling is normal and subsides quickly.
With professional settings and cooling, serious side effects (burns, scars) are extremely rare.

🧭 Conclusion

Laser hair removal targets melanin in the follicles with safe, focused light.
Only hairs in the growth phase are destroyed; several sessions are required.

Diode laser (808 nm) are the most versatile and effective option.
With modern technology and strict safety standards, the treatment is gentle, safe and long-lasting.

Scientifically precise light, safely applied, means hair-free skin that stays.
