People with fair skin tend to have more noticeable redness, flushing, or dilated capillaries,
so many of you may be concerned about these issues.

　

Today, we’ll explain the types of lasers used for treating nasal telangiectasia (dilated blood vessels on the nose)
and what factors are important during the procedure—step by step.

Types of Lasers Used for Nasal Telangiectasia

 

■ Pulsed Dye Laser (PDL) — 585nm / 595nm

Examples: Candela’s Vbeam, Cynosure’s Cynergy MPX

 

PDL (Pulsed Dye Laser) uses a dye as its medium and emits wavelengths that are highly optimized for hemoglobin absorption. This allows it to destroy or coagulate blood vessels effectively.

　

The vessels commonly found on the face are mostly veins, which contain more deoxygenated hemoglobin than oxygenated hemoglobin.

 

Therefore, the 585nm and 595nm wavelengths emitted by PDL are among the most selective for targeting hemoglobin compared to other wavelengths.

　

Many of you may already be familiar with the well-known “Vbeam”,
but “Cynergy MPX” is also a pulsed dye laser, and when used properly, it can be an extremely effective device.

Advantages and Disadvantages of PDL

 

[Advantages]

• Highly effective for treating facial redness (rosacea/flushing)

• Also useful for reducing post-acne redness

 

[Disadvantages]

• Higher treatment cost

• Less effective on thicker blood vessels

• May cause significant bruising (purpura)

• Less effective on darker skin tones

■ Nd:YAG Long Pulse Laser (1064nm)

Examples: Cutera’s Excel V, Lutronic’s Clarity, and others

 

The Nd:YAG long pulse laser operates using a different mechanism from that of the PDL.

　

As shown in the chart below, the hemoglobin absorption at 1064nm is significantly lower compared to 585nm or 595nm.

　

So why is treatment still possible with Nd:YAG?

　

① When the laser is applied, hemoglobin is converted into methemoglobin, which absorbs 1064nm much more effectively

 

② The 1064nm wavelength is less absorbed by melanin, allowing it to penetrate deeper into the skin and target deeper, larger blood vessels
　(In contrast, PDL is less effective for thick or deep vessels)

 

③ Nd:YAG lasers can also emit a 532nm (KTP) wavelength, which is another hemoglobin-targeting wavelength
　(However, this wavelength is strongly absorbed by melanin and cannot reach deep layers)

　

Here are some commonly used devices

• Wontech’s V-Laser

• Cutera’s Excel V

• Lutronic’s Clarity and DermaV

 

(Apogee Elite Plus and GentleMax Pro Plus also include a 1064nm wavelength, but are mainly used for hair removal and are therefore omitted here.)

Advantages and Disadvantages of Nd:YAG Long Pulse Laser

 

[Advantages]

• Can be used on darker skin tones

• More effective for larger blood vessels

• Relatively affordable treatment cost

• Less likely to cause bruising or purpura

 

[Disadvantages]

• Less effective for general facial redness

• Not ideal for redness from acne scars

Before-and-After Photos: Nasal Telangiectasia Treatment

These photos show a case treated at our clinic using Nd:YAG long-pulse laser (1064nm or 532nm) after a single session.

　

※Possible side effects of the treatment include burns, bruising, and pigmentation.

Since our clinic does not have a PDL device, we primarily perform treatments using Nd:YAG lasers.

　

As explained above, both PDL and Nd:YAG lasers have their own suitable indications and characteristics.
When used correctly and appropriately, both can achieve effective results.

What’s important in nasal vascular laser treatment?

 

Treatments for facial redness, acne-related inflammation, and visible capillaries (telangiectasia) around the nose involve targeting hemoglobin, which makes them relatively high-difficulty procedures.

　

This is because each patient’s vascular size, depth, and skin tone are different, requiring personalized laser settings every time.

　

An experienced physician may be able to complete the treatment in 1 to 3 sessions, but for those with less experience, the treatment may take significantly longer.

　

That’s why it’s essential to choose a doctor with extensive experience in vascular laser treatments.

Clinics that have invested in premium devices like the Vbeam are also likely to have highly skilled practitioners.

(Note: Our clinic does not have a Vbeam, but we use 1064nm and 532nm lasers.)

　

We hope you find a trustworthy and skilled doctor offering treatment at a reasonable price.

In Summary (3 Key Points)

1. The two main types of lasers used for nasal blood vessel treatment are PDL and Nd:YAG long-pulse lasers.

2. Each laser has its own strengths and weaknesses—Vbeam is not always the best. Choosing the right settings based on vessel condition is key.

3. Even with a great laser, without proper technique, results may be poor. Always choose an experienced doctor.

　

We hope this article has been helpful for those considering treatment.
