“Skin spots on my face don’t even get covered by makeup.”

“I’m not sure if it’s melasma or freckles,

would Ruby Laser work?”

We get questions like these very often.

But to be honest, it’s difficult to say without seeing it accurately first, and it’s also hard to say that Ruby Laser can treat all pigmentation.

The reason is that not all pigmentation is the same.

Ruby Laser reacts precisely only to a specific color (melanin pigment), so it can be very effective for some pigments, but it may actually irritate others.

Today, let’s talk about how Ruby Laser works and which pigments it is effective for.

Jamsil Ruby Laser,

Which Pigments Is It Effective For?

  • What kind of laser device is it?
  • What types of pigmentation is it effective for?
  • Pigments that require caution

Jamsil Ruby Laser

What kind of laser device is it?

Ruby Laser uses light with a wavelength of 694 nm.

This wavelength has a very high melanin absorption rate, so it works by precisely destroying only melanin pigment with almost no effect on other skin tissues.

In other words, instead of burning the entire skin, it acts only on pigment particles, breaking them down and removing them.

That is why it responds quickly to dark or long-standing spots and freckles.

What types of pigmentation is it effective for?

The 694 nm wavelength responds especially well to brown and black pigments.

Let’s take a look at which pigments it is effective for.

  1. Freckles

Freckles are shallow brown spots in the epidermis. Because they have a high melanin density, they respond quickly to Ruby Laser, and improvement can be seen in just 1 to 2 sessions.

  1. Spots and age spots

Spots and age spots are brown to dark-brown patches limited to the epidermis. By directly breaking down melanin in the epidermis, the pigment removal effect is fast.

  1. Ota nevus and nevus of Ota-like lesions

Ota nevus and Ota-like lesions are melanin pigments located deep in the dermis, and they are widely known as difficult to treat.

So rather than trying to treat them all at once, repeated procedures are more effective for gradual improvement.

This person also had pigmentation mainly in the form of epidermal spots.

After the Ruby Laser procedure, you can see that the skin became clearer.

Pigments that require caution

Some pigments do not respond well to Ruby Laser.

Because the wavelength is concentrated on melanin, it has almost no effect on redness, flushing, or vascular pigmentation.

In such cases, a laser dedicated to blood vessels, such as DermaV, is more suitable.

Another thing to be careful about is melasma.

Melasma contains melanin mixed in the epidermis and dermis, and because inflammatory reactions can occur easily, strong Ruby Laser treatment alone may instead cause post-inflammatory hyperpigmentation (PIH).

So for melasma, it is safer to use Ruby Laser together with other lasers, such as low-output laser devices, rather than using Ruby Laser alone.

Today, we talked about something that may be helpful for those looking into Jamsil Ruby Laser.

Ruby Laser has pigments that it is suitable for, and pigments that it is not.

So please do not decide on a procedure just because you saw reviews saying Ruby Laser was effective for someone else.

Only when the location and characteristics of the pigmentation on your face are accurately distinguished, and the appropriate laser treatment is chosen accordingly, can your skin truly become clear.
