Diode laser hair removal: operation and characteristics

Diode laser hair removal is a modern and effective method for long-lasting hair removal. Diode lasers are versatile and can be used to remove hair from all skin types, thanks to their precise timing and energy accumulation mode.

Furthermore, these new procedures offer painless treatments. Diode laser hair removal: how it works and its features are what we'll be looking at in this article.

How does a diode laser work, what are its advantages, and how does it differ from others? We'll answer all these questions. Follow our guide!

What is diode laser hair removal?

Laser hair removal methods are gaining popularity as they are becoming increasingly effective and versatile, allowing them to treat all skin types and therefore hair types. Diode laser hair removal: how it works and features , let's take a closer look.

Definition

Diode laser hair removal technology uses a concentrated beam of light that targets the melanin in hair. With its specific wavelength of approximately 800 to 810 nm, optimized for even greater effectiveness and safety, it's a proven hair removal method.

A hair removal laser diode is a semiconductor instrument identical to a light-emitting diode (LED).

The junction used is pn to produce coherent light with waves that all have the same frequency and phase.

It is the laser diode which emits this coherent light by the process of amplification of this light by emission of stimulated radiation, which is therefore called a laser.

With pn junction we then speak of a laser diode.

Main features

By targeting melanin in hair follicles , the diode laser prevents hair regrowth.

This procedure is painless and can be performed on any part of the body. The main feature of the diode laser is its ability to emit a specific wavelength that is selectively absorbed by the melanin in the hair.

Unlike other hair removal techniques, diode lasers do not cause burns or scars. Diode lasers are fast and precise, and protect the skin surrounding the area being treated.

After several sessions, the use of the diode laser significantly reduces hair regrowth.

How does diode laser hair removal work?

Operating principle

As we have just seen previously, the operating principle for diode laser hair removal rests:

• The laser emits light which is absorbed by melanin (hair pigment).
• The heat generated destroys the hair follicle without damaging the surrounding skin.
• Result: lasting inhibition of hair growth.

Difference between diode laser and other lasers

The main difference between diode lasers and other lasers is their longer wavelength, which allows for deeper laser hair removal treatments. Another advantage is that they are versatile and can treat all skin types.

• Alexandrite laser : wavelength 755 nm

This type of laser is effective on light skin, but is not very suitable for dark skin.

• Nd:YAG laser: wavelength 1064 nm

This type of laser is suitable for very dark skin, however, this type of laser is less precise than the diode laser.

• Diode laser: wavelength 800 nm

The diode laser is therefore the process that offers the perfect balance between effectiveness and safety for all skin types.

Process of a diode laser session

Before treatment, a medical consultation with the practitioner aims to define and analyze the hairiness, the area to be treated and the skin prototype.

Then before the first session, advice is given, here it is:

• You must shave the hair the day before the session, shave and especially not wax.
• You should not have sunbathed beforehand, and you should arrive without a tan so as not to distort the necessary contrast between skin and hair color.
• It is useful to respect the treatment schedule and the spacing between sessions.
• Do not bleach the hair.
• The hair should not be plucked in any way.

The advantages of diode laser for hair removal

In summary, the advantages of diode laser for hair removal are:

Versatility

• Suitable for all areas of the body (face, legs, bikini line, back).
• Effective on a wide range of skin and hair colors.

Speed ​​and comfort

• Reduced processing time thanks to rapid coverage of large areas.
• Cooling technology to minimize discomfort.

Lasting results

• Significant reduction in hair density after a few sessions.
• Permanent reduction of regrowth with occasional touch-ups.

The disadvantages and limitations of the diode laser

Regarding the disadvantages and limitations of the diode laser, we note:

• Diode laser hair removal requires several sessions to achieve optimal results, averaging 6 to 8 sessions.
• This type of laser remains less effective for very light, white or red hair due to the lack of melanin.
• Higher initial cost than traditional hair removal methods.
• Precautions to take to avoid irritation: avoid the sun before and after sessions.

Who is diode laser hair removal for?

Suitable skin and hair

• Suitable for all skin types, including tanned or dark skin.
• Ideal for dark and thick hair.
• Slightly less suitable for fine hair.

Contraindications

• Not recommended for pregnant or breastfeeding women.
• Avoid if skin is irritated, tanned or if certain photosensitizing drug treatments are being taken.

Conclusion

Diode laser hair removal remains one of the most effective and versatile laser hair removal methods available.

How the laser works, the advantages of being able to treat all skin types and optimal treatment results after 6 or 8 sessions, diode hair removal is currently the most effective.

Finally, the diode laser with its specific, optimized wavelength of 800 to 810 nm offers even greater efficiency and safety for all areas treated.

To take advantage of this innovative technology, you simply need to follow all the advice and instructions given by the practitioner you have selected in a cosmetic clinic, beauty center or beauty salon specializing in laser hair removal methods.

Frequently Asked Questions

How does diode laser hair removal work?

Diode laser permanent hair removal technology uses light waves at a wavelength of 810 nm . The speed of the shots may vary depending on the treatment protocols. This laser hair removal process permanently removes hair from all parts of the body.

What is the difference between diode laser and normal laser?

The diode laser penetrates slightly deeper than the alexandrite laser, so it will destroy thick, dark, and deep hairs. While the diode laser is still a decent laser, the alexandrite laser is superior in terms of overall effectiveness for fine hairs.

Is the diode laser effective?

Diode lasers work particularly well on light skin and dark hair. Diode lasers are highly effective, fast, and precise. They have a wavelength of 810 nm and deep penetration capabilities.

What is the most effective laser for hair removal?

Although the diode laser remains a very competent, versatile and efficient laser, it should be noted that the Alexandrite laser is superior in terms of overall effectiveness, particularly for fine hair.
