Expect Skin Changes in a Short Period with Lentigo Laser Treatment

Management of lentigo lesions can be relatively straightforward.

Here, we meticulously treat dark and distinct lentigines primarily using a 532nm Nd:YAG laser.

Depending on the condition, any finely remaining pigment can then be refined with an Er:YAG Erbium YAG laser.

In most cases, noticeable changes can be expected within approximately 2 to 3 treatment sessions.

Through meticulous diagnosis and a personalized plan, we propose an efficient treatment process, thereby reducing the burden of unnecessary repeat treatments.

We approach lentigo lesion management with careful consideration to provide you with the best assistance.

Effort and Philosophy for Meticulous Care

Here, we prioritize the thoroughness of the treatment process and limit the number of patients seen by each doctor per day.

To dedicate more focus and time to each individual, we adjust the daily patient count.

This approach allows for detailed guidance and personalized plans at every stage, from consultation to treatment and post-care. Additionally, we ensure ample time to meticulously observe and consider changes or reactions in the skin condition of our visiting patients.

As a result, this contributes to enhancing the accuracy of treatments and ensures a meticulous medical approach that goes beyond simply repeating procedures.

Here, we place more emphasis on the thorough results of the treatment than on time allocation, deeply focusing on the skin condition of each individual who visits.

Adjusting Laser Settings to Individual Characteristics

We meticulously examine the patient's skin tone, the size and depth of the lesion, and skin sensitivity to adjust laser settings such as spot size, pulse energy, and fluence.

For instance, for light skin with superficial pigmentation, we perform precise treatments using a small spot size and high energy. For skin prone to post-inflammatory hyperpigmentation, we meticulously adjust the output to minimize skin burden.

Such fine adjustments can positively impact the accuracy and satisfaction of treatment results, even when using the same laser equipment,

which is one of the crucial aspects.

Systematic Approach to Skin Recovery After Treatment

Because the 532nm laser reacts quickly to the lesion, temporary scabs or erythema may appear after treatment. Therefore, it is crucial to pay special attention to skin regeneration management and UV protection.

Since individual pain sensitivity to 532nm laser and secondary Erbium YAG laser treatments may vary, we consult beforehand to determine whether to use anesthetic cream. After treatment, cooling procedures and soothing packs are used to comfort the skin.

Furthermore, dressings such as Duoderm are provided to aid recovery and protect the skin from UV rays.

Personalized Treatment Plan Considering Not Only Lentigo but Also Overall Pigmented Lesions

Many patients who come for lentigo removal often have other dermal pigments, such as melasma, in addition to lentigines.

Rather than simply targeting lentigines, a comprehensive approach that considers various pigmented lesions distributed across the entire skin may be necessary.

We analyze facial pigmentation through in-depth consultation with the patient and by utilizing diagnostic equipment. Based on this, we discuss and decide on the treatment direction, such as whether to target only epidermal pigmentation or to attempt overall pigment improvement.

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

Causes of Lentigo (Solar Lentigo)

Solar lentigo is a flat, brownish pigmented lesion primarily caused by UV exposure and skin aging.

When melanocyte activity becomes excessively vigorous, melanin pigment accumulates more than necessary in specific areas.

Continuous exposure to UV radiation causes melanin production to persist without stopping.

Furthermore, as one ages, the skin's ability to recover and process pigments diminishes, leading to lesions gradually becoming darker and expanding.

They are mainly observed on the face, back of the hands, and arms, characterized by clear borders and a dark brown color.

Main Occurrence Areas and Characteristics of Lentigo Lesions

Lentigines typically appear confined to the epidermis, the outermost layer of the skin.

Specifically, melanocytes in the basal layer of the epidermis become excessively activated by UV stimulation,

leading to a concentrated accumulation of melanin pigment in one area.

During histopathological examination, it is confirmed that melanin is excessively deposited within the epidermis without invading the dermis.

Compared to the surrounding normal skin tissue, the borders are often quite distinctly demarcated.

For these reasons, they tend to respond well to epidermal-targeting laser treatments such as Q-switched 532nm,

It is distinguished from melasma or mixed types of pigmented lesions that affect deep dermis layers of the skin.

Characteristics of 532nm Wavelength

The 532nm wavelength is a green-spectrum wavelength with a relatively high absorption rate for melanin pigment. It selectively targets pigmented lesions primarily located in the epidermal layer of the skin.

Most 532nm lasers utilize a Q-switched method. This involves momentarily irradiating powerful energy for a very short duration, in nanoseconds, to precisely destroy only the pigment particles.

This short-pulse energy is selectively absorbed by melanin and converted into thermal energy. Simultaneously, a photomechanical shock occurs, breaking down melanin particles into smaller fragments.

Some of the decomposed pigment turns into small scabs and naturally falls off. The rest can be expelled from the body via the lymphatic system by macrophages.

As the destroyed pigment is gradually removed in this manner, you can expect noticeable lightening or improvement of the lentigo.

About Lentigo Removal Treatment

While choosing the appropriate laser wavelength is crucial for lentigo treatment,

the success of the treatment is not determined solely by wavelength selection.

A comprehensive treatment plan, including accurate diagnosis and settings tailored to your individual skin condition, must be carried out simultaneously.

Through this integrated approach, you can finally achieve satisfactory treatment results.
