How Effective Is It?

'I think I've had toning treatments more than five times, one after another.

But even though it feels like it should have disappeared by now,

it somehow seems to be getting worse instead...?

I often hear stories from people saying that their spots and blemishes didn't go away easily even after multiple laser sessions.

When I recommend laser treatment again to people like this, they sometimes look at me with a skeptical eye. So, to help them understand enough, the explanation gets long, and I end up becoming a bit of a long-winded talker.

In fact, there are many different laser devices used to remove freckles and blemishes.

To see proper results, they need to be used for the right purpose.

So today, I’ll explain in detail, focusing on the principles and effects, how effective the ruby laser commonly used in pigment treatment can generally be.

Ruby Laser - The Secret of the 694nm Wavelength

The ruby laser is a laser device that emits a red beam with a wavelength of 694nm.

This wavelength has a selective absorption rate for melanin that is more than 3 to 10 times higher.

Simply put, it means that the dark melanin pigment in the skin absorbs light at this wavelength especially well.

At the same time, because it has little effect on the surrounding normal skin tissue or blood vessels, it is characterized by a lower concern for surface skin damage.

When talking about the ruby laser, there is a comparison I often use when explaining it in the consultation room.

I explain that the ruby laser is more like hitting the pigment problem accurately with a single strong strike, rather than tapping lightly many times.

Of course, it depends on the depth and type of pigment, but because the energy delivery itself is different by default, it can concentrate energy over a short period of time and break down pigment more effectively.

Yeongdeungpo Ruby Laser Which pigment concerns is it suitable for?

There are many different pigment issues, such as freckles, spots, and age spots.

Let’s look at the cases where ruby laser treatment is especially effective.

  • Freckles and spots

Freckles appear as small brown spots, scattered around the nose and cheeks.

They are mainly caused by genetic factors and sun exposure, and since melanin located in the epidermis is the main cause, they tend to respond well to ruby laser treatment.

Also, spots are irregular pigmentation that develops after long-term sun exposure, and they usually start appearing in the late 30s.

Because they often occur from the epidermis to the shallow part of the dermis, good results can often be expected in relatively few sessions.

  • Age spots

They appear as slightly raised spots on the skin surface, and are usually brown or black.

Since the main causes are excessive proliferation of keratinocytes along with melanin pigmentation, ruby laser tends to be effective.

However, because the raised part may not become completely flat with laser alone, other methods are sometimes used together depending on the case.

  • Tattoo removal

It can break down artificial pigment injected into the skin, and the number of sessions needed may vary depending on the tattoo color and depth.

Darker tattoos tend to respond relatively better.

However, because each person’s pigment depth and skin type are different, please take this only as a reference. Before actual treatment, we recommend getting a diagnosis first and then proceeding.

Yeongdeungpo Ruby Laser Can it be used in all situations?

The ruby laser is certainly a suitable method for many pigment concerns, but it may not be the best option in every situation.

I think I need to be honest about this part.

For example, pigment issues such as melasma, which often recur and are strongly affected by hormones, may respond better when ruby laser is combined with other whitening care and toning rather than used alone.

Even if they look like similar problems on the surface, they may actually be completely different pigment conditions, so an accurate diagnosis is very important, and the treatment plan must be carefully designed.

For example, if it turns out to be deep-rooted melasma and a random laser is used carelessly based on a rough look, it could actually make the problem worse.

That is why it is important to understand and consider several factors in advance, such as the depth of the pigment, skin thickness, and regenerative ability, so the treatment can lead to good results.

Yeongdeungpo Ruby Laser How should it be cared for?

You do not need to worry about every little thing after the procedure, but there are still a few points that require some attention.

First, if a scab forms, do not pick at it with your hands or irritate it. It will naturally fall off over time anyway, so just keep up with moisturizing thoroughly.

Also, when looking at the common points in many disappointing(?) reviews, one thing that often stands out is that they were less careful with sun protection than expected.

Because regenerating skin is very vulnerable to ultraviolet rays, you should always apply sunscreen with at least SPF 30 to help prevent pigmentation.

Today, we looked in detail at how effective the Yeongdeungpo Ruby Laser can be.

However, how well it works also depends on the severity of your pigment concerns.

If you are considering ruby laser treatment, the first step is to accurately identify what kind of skin pigmentation you have and how deeply it is located.

So I recommend getting a thorough consultation, checking whether the diagnosis is careful and detailed, and whether a treatment plan tailored specifically to your concern is created before making a decision.
