[Pigmentation Removal] Lentigo Laser

Distinction 1 Lentigo Laser Treatment: Expect Improvement in a Short Period

Your lentigo concerns can be resolved relatively quickly.

Here, we first precisely treat dark and distinct lentigo areas using a 532nm Nd:YAG laser, identical to the 'LiX Laser'.

Afterward, only if deemed necessary, we meticulously clear remaining faint pigmentation using an Er:YAG erbium laser.

Most cases are completed within approximately 2-3 sessions.

Rather than unnecessarily repetitive procedures, we strive to achieve clear results in a short period based on accurate diagnosis and a well-planned approach.

Our goal for lentigo management here is to help you achieve satisfactory improvement.

Distinction 2 Why Meticulous Care is Needed

We prioritize the quality of our treatments, so we limit the number of patients seen by each medical staff member per day.

The number of daily appointments per medical professional is set lower than the average in the relevant field. This is intended to dedicate sufficient time and focus to each individual.

Thanks to this operational approach, we can provide detailed explanations and create individual customized plans throughout the entire process, from consultation to treatment and post-care. It also allows us ample time to closely observe and respond to the patient's skin condition and reactions.

As a result, treatment accuracy is enhanced, and patient satisfaction can also improve. This aims for 'dedicated medical care' rather than mere routine treatment.

Here, we prioritize the results achieved over the time spent, focusing with sincerity on the skin of each individual who visits. It seems many people visit us through referrals because of this.

Distinction 3 Settings Customized to Each Individual's Condition

We adjust laser settings such as spot size, pulse energy, and fluence, considering the patient's skin tone, the size and depth of the pigmented lesion, and the skin's reaction.

For example, for bright skin with shallow pigmentation, we meticulously treat it with a small spot size and high energy. Conversely, for skin prone to hyperpigmentation, we adjust the laser output to perform the procedure safely.

Such detailed customized settings enhance the precision and satisfaction of treatment results, even when using the same laser equipment,

serving as an important factor.

Distinction 4 Post-Treatment Recovery Plan

Since the 532nm laser has a relatively fast reaction, temporary scabbing or redness may occur after the treatment. Therefore, regenerative care and UV protection are extremely important.

When undergoing 532nm laser or secondary erbium YAG laser treatment, individual sensitivity to pain may vary, so we decide whether to apply anesthetic cream through a prior consultation. After the procedure, cooling treatment and a Jaungo modeling pack are used to help soothe the skin.

In addition, we keep Duoderm available in our clinic to assist with recovery and UV protection.

Distinction 5 Treatment Plan Considering Overall Pigmentation, Not Just Lentigines

Many people who visit for lentigo removal often have dermal pigmented lesions like melasma in addition to lentigines.

While focusing solely on removing lentigines is important, we believe many people wish to improve the overall mottled pigmentation on their face.

Therefore, after a thorough consultation with the patient using diagnostic equipment, we categorize the pigments on the face. Based on this, we carefully decide the treatment direction: whether to target only epidermal pigmentation or to manage overall pigmentation simultaneously.

This approach helps our patients achieve brighter and clearer complexions.

Why do lentigines occur?

Solar lentigo is a flat, brown pigmented lesion that primarily appears due to UV exposure and skin aging.

This refers to a condition where melanin cells are excessively activated, leading to an over-accumulation of pigment in specific areas.

Repeated exposure to UV radiation continuously triggers melanin production,

and as one ages, the skin's regenerative capacity and pigment metabolism decline, which can gradually lead to darker color and wider spread.

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

Location of Lentigo Distribution

Lentigines (solar lentigines) primarily appear confined to the epidermis of the skin.

Specifically, melanocytes in the basal layer become excessively activated due to UV stimulation,

resulting in the localized accumulation of melanin pigment.

Histologically, lentigines do not penetrate the dermis but are characterized by an excessive accumulation of melanin within the epidermis,

and their borders with surrounding normal skin tissue are relatively clear.

Due to these characteristics, they tend to respond well to treatments targeting the epidermal layer, such as Q-switched 532nm lasers.

Solar lentigo, which primarily appears in the epidermal layer, is distinct from melasma or complex pigmented lesions that affect even the dermal layer.

532nm Laser Wavelength

Melanin pigment particularly absorbs the 532nm wavelength well. This green wavelength primarily targets and improves pigmented lesions located in the epidermis, the outermost layer of the skin.

The 532nm laser typically utilizes a Q-switched mode. This focuses and delivers high-power energy in very short nanosecond pulses. As a result, it can precisely destroy only the pigment particles while minimizing damage to surrounding tissues.

When short pulses are selectively absorbed by melanin, they are converted into thermal energy. Simultaneously, photomechanical shock occurs, causing the melanin particles to break into tiny fragments.

Some of these finely fragmented pigments naturally shed as scabs, while others are processed by the body's macrophages and gradually eliminated through the lymphatic system.

As the destroyed pigment gradually disappears, you can expect the solar lentigo to become visibly lighter or generally fade.

Approach to Solar Lentigo Removal Treatment

The 532nm laser is considered an effective wavelength for solar lentigo treatment.

However, the success of the treatment does not simply depend on selecting the wavelength.

An integrated approach is necessary, including accurately diagnosing the individual's skin condition and the characteristics of the solar lentigo, and then applying appropriate treatment settings.

Only when these delicate processes are supported can the satisfaction with the treatment results be enhanced.
