What is the difference between a YAG diode and a diode?

Diode and YAG lasers are methods for permanently removing body hair. For those with excessive body hair that causes a lack of self-confidence, Diode and YAG lasers are considered highly effective and provide noticeable results. Today, Romrawin Clinic will answer your questions about... Which type of laser hair removal is best?This article will explain the differences between Diode and YAG lasers.

What is the difference between a diode and a YAG diode?

Nowadays, medical technology has advanced with laser devices that help treat skin problems, including various types of hair removal.เลเซอร์ร้, Brazilian Laser หรือBikini laser Each type of laser produces different laser results. Now, let's look at the differences between diode and YAG lasers and how they work, as follows:

Diode Laser Machine

machine Diode Laser Laser hair removal is a type of hair removal device that uses thermal energy from laser light waves to remove hair. The light waves have specific wavelengths that can destroy hair follicles deep within the skin. A variety of wavelengths are available, such as 800-810, 940, and 1064-1,350 nanometers, resulting in flexibility for treating different areas of the skin.

The working principle of a diode laser is to emit laser light that causes pigment in the skin to absorb the light energy and convert it into heat. This heat then destroys hair follicle cells from the root and binds with melanin pigment, causing the hair in the treated area to become lighter in color. It also gradually reduces the number of hairs. Diode lasers are suitable for people with fair or medium skin tones, as they are most effective for lasering large areas of skin, such as...Laser hair removal for legs Or, for example, laser hair removal on the arms.

YAG Laser Machine

machine YAG Laser It is a machine.เลเหWith the widest range of wavelengths among all hair removal devices, the YAG Laser can remove laser rays down to 7 millimeters below the skin's surface. Its Yttrium Aluminum Garnet laser energy has a wavelength of 1,064 nanometers. Furthermore, the use of a smaller applicator head allows the YAG laser to reach a more comprehensive area during treatment.

The working principle of a YAG laser is to emit laser energy that targets melanin pigment and hair follicles. When the hair follicle weakens from the damage, it eventually falls out. YAG lasers are suitable for all skin tones and regardless of hair color (dark or light). This method can be used for various hair removal applications, including facial hair removal.Laser mustache Or theLaser hair removal for the genitals. etc.

Diode vs. YAG laser: Which type is right for you for hair removal? 

Let's continue and see which areas each Diode laser and YAG laser are capable of removing hair from. Let's go!

  • Diode Laser
    Diode laser hair removal is suitable for those with fair or medium skin tones who want to remove hair over large areas, such as arms and legs. However, those with dark or tan skin should choose YAG laser hair removal instead.
  • YAG Laser
    YAG laser hair removal is suitable for all skin tones and whether you have dark or light hair. This method is ideal for areas with limited space and requiring precision, such as underarms, beard, face, and intimate areas.

Besides hair removal with diode and YAG lasers, there are other equally popular hair removal methods, such as IPL. You can read more about it here: IPL hair removal

Which is better for hair removal: diode or YAG laser?

YAG laser vs. diode

Now that we know who YAG and Diode lasers are suitable for, many people probably have the next question: which is better, a YAG or a Diode laser? Let's find the answer in this section.

  • Laser efficiency

Diode and YAG lasers differ in their efficiency based on wavelength. Diode lasers have wavelengths of 800-810, 940, and 1064-1,350 nanometers, making their laser light more flexible and wider-ranging than YAG lasers, which have a wavelength of 1,064 nanometers. Therefore, diode lasers are more effective at removing hair follicles and the blood vessels that supply the hair follicles than YAG lasers.

  • Pain during laser treatment.

Diode and YAG lasers differ in their level of pain. Diode lasers are less painful than YAG lasers because they use a cooling system during the laser treatment to reduce skin burns. YAG lasers, however, lack a cooling system, which may cause slight discomfort during treatment.

  • Laser cost

Diode and YAG laser treatments cost between 1,000 and 3,000 baht per session. The price depends on the area being treated and other factors. Those interested in laser hair removal should consult a doctor to determine the most suitable treatment for their skin.

  • Number of laser treatments

Diode and YAG laser treatments typically show noticeable results after 5-8 sessions, but some individuals may see significant results from the first treatment. This depends on several factors such as the area being treated, skin condition, hair color, and hair quantity of each individual.

Summary of Diode and YAG. 

Diode and YAG lasers are effective hair removal methods that remove hair from the subcutaneous layer and permanently inhibit the growth of new hair. Both types of laser hair removal are suitable for Thai skin types and address all types of body hair problems.
