Permanent hair removal

Quad Wavelength Diode Laser (4 wavelengths)

Do you want to do permanent hair removal in Gothenburg with the latest laser technology?

We treat with an advanced quad wavelength diode laser - an updated generation of laser for permanent hair reduction that combines four different wavelengths in the same treatment.

This is a more modern technology than traditional hair removal lasers, which often work with only one or three wavelengths.

We offer safe and personalised laser hair removal in Gothenburg for both women and men - adapted to skin type, hair type and area.

What is permanent hair removal by laser?

Permanent hair removal by laser involves guiding light energy into the hair follicle where the pigment absorbs the energy. The heat affects the hair follicle and reduces its ability to produce new hair.

The treatment is more correctly called permanent hair reduction, as hair growth is biological and individual. The goal is a long-lasting, clear and even reduction of hair growth.

 

Quad Wavelength - Next generation diode laser in Gothenburg

Most diode lasers operate at one main wavelength (usually 808 nm).

Our technology combines:

  • 755 nm - effective for shallower and finer hair
  • 808 nm - the classic and proven diode wavelength
  • 940 nm - contributes to stable and even energy distribution
  • 1064 nm - deeper penetration and improved treatment of deeper hair follicles

It is precisely the fourth wavelength - 1064 nm - that makes the difference.

 

What makes 1064 nm special?

1064 nm has a deeper penetration capability than shorter wavelengths. This means that it:
  • reaches deeper lying hair follicles
  • complements other wavelengths for better coverage
  • can provide stable energy delivery even with coarser hair
  • is suitable even for darker skin types

When all four wavelengths are used simultaneously, a so-called multi-depth synergy effect (sometimes called the “sandwich effect”).

Rather than working at a single depth, the energy covers the hair follicle from superficial to deeper levels. It provides:

  • more complete energy coverage
  • more even response across the treatment area
  • improved effectiveness over a treatment series
  • possibility to treat more hair types in the same session
This is why quad wavelength technology is considered an upgraded and more versatile solution in modern laser hair removal.

Which areas can be treated?

We offer permanent hair removal in Gothenburg for:
  • Face (upper lip, chin, whiskers)
  • Armpits
  • Mr Ben
  • Bikini line and Brazilian
  • Back and chest
  • Mage
  • Treatment is always personalised.

How many treatments are needed?

Laser only affects hair in the active growth phase. Therefore, several treatments are required.
Usually needed:
  • 6-10 treatments
  • Every 6-10 weeks, depending on the area and individual hair cycle
The number of treatments varies depending on:
  • Hormonal impact
  • Hair colour and thickness
  • Skin type
  • Genetic factors
Results cannot be guaranteed, as hair growth is individual. The goal is long-lasting and clear hair reduction - not absolute hair freedom.

When do you see results?

Most people experience:
  • Reduced hair growth after 2-3 treatments
  • Thinning and thinning hair
  • Slower regrowth
The end result develops gradually over the entire treatment series.

After treatment - what is normal?

After laser hair removal, the area may react with:
  • Root canal
  • Slight swelling
  • Thermal sensation
  • Mild tenderness
  • Mild itching
These reactions are normal and usually disappear within a few hours to a few days.

Important before and after treatment

Before treatment:

  • The area should be shaved
  • Avoid waxing and epilation
  • Avoid sunbathing at least 2 weeks before treatment

After treatment:

  • Avoid strong sun
  • Use SPF
  • Avoid active skin products in the area for a few days

Contraindications

  • Treatment is not carried out at:
  • Pregnancy
  • Active skin infection
  • Ongoing cancer treatment
  • Photosensitive diseases
  • Photosensitising medicines
  • Heavily tanned skin

Relative contraindications:

  • Hormonal disorders or hormone replacement therapy
  • Active or severe herpes outbreaks in the treatment area
Individual medical assessment is always done before treatment.
