What makes Kkeut Oriental Clinic's lentigo laser treatment different? 

Distinguishing Feature 1: Laser treatment with an expected improvement in lentigo with fewer sessions

Lentigo treatment can be performed relatively quickly.

At our medical institution, we first use a 532nm Nd:YAG laser to focus on distinct and prominent lentigo lesions.

Afterward, depending on the condition, an Er:YAG laser is secondarily applied to delicately manage even the remaining faint pigmentation.

In most cases, improvement can be expected with approximately 2-3 sessions.

We aim for positive changes in a short time by reducing unnecessary repetitive treatments and implementing precise diagnoses and customized plans.

We will strive to help you achieve skin improvement through lentigo treatment.

Distinguishing Feature 2: Why we aim for a meticulous treatment process

We prioritize the completeness of the treatment and limit the number of patients seen per medical professional per day.

This is to allocate sufficient time and focus on each individual. We limit the number of patients that can be booked per medical professional per day.

In this way, detailed explanations and individualized customized plans are established throughout the consultation, treatment, and aftercare processes. We take the time to meticulously observe the patient's skin condition and response, allowing us to incorporate it into the treatment.

This enhances the precision of the treatment and allows us to provide medical services that focus on individual patients rather than just repetitive consultations.

We invest sufficient time in the treatment process to achieve satisfactory results. We focus on the skin condition of each individual and perform treatments meticulously.

Distinguishing Feature 3: Laser settings customized for individual skin conditions

We comprehensively consider the patient's skin tone, the size and depth of the lesion, and skin reactivity to adjust the laser's spot size, pulse energy, and fluence values.

For example, for bright skin tones with shallow pigmentation, we perform precise irradiation with a small spot size and appropriate energy. Conversely, for skin prone to hyperpigmentation, we carefully adjust the laser output to minimize skin burden.

These meticulous laser settings contribute to the precision of the treatment and the improvement of patient satisfaction, even with the same equipment,

and are a crucial factor.

Distinguishing Feature 4: Post-treatment recovery management

A 532nm laser can cause rapid reactions such as scabs or temporary redness after treatment. Therefore, focusing on regenerative care and sun protection is crucial.

As pain sensitivity during laser treatment can vary among patients, the use of anesthetic cream is decided during a pre-consultation. After treatment, cooling and Jauungo modeling packs are used to help soothe the skin.

Additionally, we provide DuoDerm to assist with recovery and sun protection.

Distinguishing Feature 5: A customized approach that considers overall pigmented lesions beyond just lentigo

Many patients who come for lentigo removal also have dermal pigmentation such as melasma.

Of course, it is also possible to treat only lentigo. However, some patients also wish for overall improvement in facial pigmentation.

Through detailed consultation with the patient and diagnostic device analysis, we accurately classify the facial pigmented lesions. Subsequently, we jointly decide on the treatment direction, whether to primarily improve only epidermal pigmentation or to aim for overall management of pigmented lesions.

Through this, we strive to help you achieve a clearer and brighter complexion.

What causes lentigo?

Solar lentigo is a flat, brown pigmented lesion that primarily occurs due to exposure to ultraviolet (UV) light or as skin aging progresses.

It refers to a state where excessive pigment accumulates in specific areas due to the overactivity of melanocytes.

Continuous exposure to UV light leads to an ongoing production of melanin pigment,

and as we age, skin regeneration and pigment metabolism functions decline, which can cause lentigo to darken and spread more widely.

They typically appear on the face, back of the hands, and arms, exhibiting distinct borders and a dark brown color.

Location of lentigo lesions

Solar lentigo typically appears only in the epidermal layer of the skin.

Specifically, when melanocytes in the basal layer, the lowest layer of the epidermis, become overactivated due to UV stimulation,

melanin pigment accumulates intensively in specific areas.

Histologically, it is a condition where melanin is excessively accumulated within the epidermis without penetrating the dermal layer,

and is characterized by forming relatively clear borders with the surrounding normal skin tissue.

Due to these characteristics, a positive response can be expected from treatments targeting epidermal pigmentation, such as Q-switched 532nm lasers.

This treatment differs in approach from melasma or mixed-type pigmented lesions that occur throughout the dermal layer.

Understanding the 532nm Wavelength

The green-spectrum 532nm wavelength has the characteristic of being effectively absorbed by melanin pigment. This selectively helps it react only to pigmented lesions primarily located in the epidermal layer of the skin.

Generally, 532nm lasers utilize a Q-switched method. This method focuses on precisely destroying only pigment particles without damaging surrounding tissue, by instantaneously emitting powerful energy in extremely short nanosecond pulses.

Such short-pulse energy is concentratedly absorbed only by melanin pigment. The absorbed energy then converts into heat, simultaneously creating a photomechanical shock phenomenon that efficiently breaks down melanin particles.

Some of the fragmented pigment pieces transform into tiny scabs and naturally fall off. Additionally, the remaining pigment is processed by macrophages within the body and gradually expelled through the lymphatic system.

As the destroyed pigment is gradually removed in this manner, you can expect the lentigo lesions to lighten or improve in appearance.

Approach to Lentigo Removal Treatment

In the treatment of lentigo lesions, specific laser wavelengths are known to be highly effective methods.

However, simply choosing a wavelength does not determine the outcome of the treatment.

When accompanied by a comprehensive treatment plan, including accurate lesion diagnosis and personalized equipment settings,

you can experience more satisfying improvements and a difference in results.
