Laser hair removal: techniques, results & expert tips

Laser hair removal - everything you need to know

Today, laser hair removal is the most advanced method for permanently reducing annoying body hair. It is based on the principle of selective photothermolysis, in which light is directed specifically at the hair root. This destroys the hair matrix without damaging the surrounding tissue. The treatment is safe, scientifically researched and suitable for many people with different skin and hair types - provided it is carried out professionally and customized.

If you're wondering how the method works, whether it works for you, how much it costs or how you should prepare - this comprehensive guide answers it all.

How does laser treatment work?

In laser hair removal, light energy is converted into heat to destroy specific hair follicles. The method only attacks hair roots in the active growth phase (anagen phase). Several sessions are therefore necessary to permanently remove all hair. The technique of photothermolysis has been continuously developed since the 1990s and is now mature in both medical and cosmetic applications. It is rated as effective and safe by Apotheken Umschau, among others.

Alexandrite or Nd:YAG - which laser is right for you?

The alexandrite laser (755 nm) is particularly effective on light skin (Fitzpatrick I-III) with dark hair. Its short wavelength works close to the surface and offers excellent results on areas such as the face, armpits or intimate areas. This laser has been medically tested and is recommended by dermatologists, for example, according to the German Dermatology Association (DDG).

The Nd:YAG laser (1064 nm) has a longer wavelength, which means it penetrates deeper into the skin and is also suitable for darker skin types (IV-VI). Treatment with this laser reduces the risk of hyper- or hypopigmentation. According to Netdoktor, it is currently the safest laser for heavily pigmented skin.

Who is laser hair removal suitable for?

The basis for choosing the right treatment is the so-called Fitzpatrick scale, which divides skin types into six categories. Light skin with dark hair delivers the best results, but modern laser technology means that people with darker skin can now also be treated - albeit with adjusted parameters.

Laser hair removal is not suitable for pregnant women, those taking certain medications (e.g. isotretinoin), active skin infections or diseases such as lupus. Tattoos or moles in the target area are also excluded.

The course of treatment

Before the meeting

A consultation, including a skin analysis, takes place before the first treatment. You should avoid sunbathing and self-tanning for at least four weeks beforehand. The day before, you must shave the area to be treated thoroughly - but do not epilate or wax.

During the session

A short test pulse checks tolerance. The skin is then protected with a cooling system and the laser is passed over the area pulse by pulse. Depending on the area, a session lasts between 10 minutes (e.g. upper lip) and 90 minutes (legs or back).

After the session

The skin may be slightly reddened or swollen. You should not use any irritating products for the first 48 hours. You should avoid intense heat (sauna, sport), sun and chlorinated water for at least a week. Gentle skin care with aloe vera, panthenol or cooling compresses is recommended.

How safe is the method?

According to the German Medical Association, laser hair removal is very safe when used correctly. Slight side effects such as redness or a feeling of tightness are normal and temporary. However, incorrect laser selection or untrained staff can lead to pigment shifts or minor burns. It is therefore crucial to only undergo treatment at certified studios or medically supervised institutes.

How many sessions do you need?

As lasers can only affect hair in the anagen phase, 6-10 sessions are usually required at intervals of 4-8 weeks. Fine or hormonally controlled hair (e.g. PCOS) may require more sessions. Clinical studies also show that different areas of the body respond differently to lasers - armpits and bikini line often respond more quickly, legs and face more slowly.

What does the treatment cost?

The costs depend on the size of the area, hair structure and number of sessions. Example prices:

  • Armpits: 80-120 € per session
  • Bikini line: 100-150 €
  • Legs complete: 250-350 €
  • Face: 90-130 €
  • Back (men): 180-280 €

Many studios offer package prices with a 10-50% discount or monthly installments. A cost overview helps with the comparison.

Tips for better results

You will get the best results if you take all the care instructions seriously:

  • Avoid waxing and plucking - otherwise the laser will miss the target (the hair root).
  • Use gentle exfoliants regularly - this prevents the hair from growing in.
  • Avoid the sun consistently - UV radiation increases the risk of side effects.
  • Shave only with a sharp blade - do not risk skin injuries.

Hormonal fluctuations (e.g. due to puberty, pregnancy or PCOS) can cause new hair growth - permanent straightening may require more touch-ups.

Frequently asked questions (FAQ)

How long do the results of laser hair removal last?

After successful completion of the treatment, many areas remain hair-free for several years. One or two annual refresher sessions help to stabilize the results in the long term.

How often do I have to come for follow-up treatment?

Depending on the area of the body, hair density and hormonal influences, we recommend one maintenance session per year - more often if necessary in the case of PCOS or hormonally induced hair growth.

Which is better: laser or IPL?

Laser devices such as alexandrite or Nd:YAG are more targeted, more effective and safer than IPL. IPL is a cheaper option, but with less depth and precision.

What do I need to consider before the session?

No tanning beds or self-tanning products four weeks beforehand. Shave the day before, no plucking or waxing. Please leave skin without make-up, without perfume and dry.

What does the skin look like immediately after the treatment?

Slight redness and minimal swelling are normal and usually disappear after a few hours. Cooling and panthenol can help with sensitive skin.

Can laser treatment help with ingrown hairs?

Yes, in the long term, razor bumps and ingrown hairs often disappear completely, as the hair structure grows back finer and softer or disappears altogether.

Does laser also help with PCOS-related hair growth?

Laser can also be very effective for hormonal hair growth caused by PCOS, although more sessions and follow-up treatments are usually required.

How quickly will I see results?

Visible hair loss often begins 10-14 days after the first session. Depending on the area, clear results are usually visible from the third session.

Can I use make-up or deodorant after the session?

Please refrain from using both for 24 hours. The skin is sensitive after the treatment and should be protected to avoid irritation.

Is laser hair removal possible in summer?

Treatments in summer are possible as long as direct sunlight is avoided. Tanning must be avoided four weeks before the start and two weeks after each session.
