Skin Treatment Using Two Types of Lasers

Moles are lesions that form when melanin-producing cells abnormally increase in number in the epidermis or dermis of the skin.

While they may appear to be simple hyperpigmentation on the surface, the treatment approach can vary depending on the mole's location and depth.

Erbium YAG laser is effective for precisely ablating the skin. When removing shallow moles located in the epidermis, it allows for natural removal while minimizing damage to surrounding skin.

This laser minimizes scarring, allowing for excellent cosmetic results. It is especially suitable for facial mole removal. Subsequently, a delicate cauterization of the mole's base with a CO2 laser can help treat any melanin cells that might remain in deeper layers, reducing the possibility of recurrence. This contributes to preventing 'recurrent moles,' which appear to be removed but regrow because their roots remain.

Specifically, a CO2 laser finishing touch may be considered in the following cases:

-When a mole is slightly raised or feels thick to the touch

-When there is a history of a mole recurring in the same area

-When a lesion is suspected to be a nevus located in the deep dermal layer, such as a blue mole or a grayish-brown mole

Flat warts are viral skin lesions caused by human papillomavirus (HPV) infection. They appear as widespread, thin, flat, brownish or flesh-colored small lesions within the epidermal layer. They tend to occur more frequently when immunity is low, and since they can spread to other areas through self-touching, early treatment is crucial.

Erbium YAG laser is effective for uniformly removing the epidermal layer, making it useful for treating widespread flat warts

in a single session. This procedure helps to evenly remove lesions while minimizing skin damage. However, due to the nature of viral lesions, removing only the surface lesions carries a risk of recurrence. In such cases, a finishing process involving applying subtle thermal damage to the area surrounding the lesion with a CO2 laser can be a clinically significant approach to further treat any viral infected cells that may remain in the epidermis and its surroundings, thereby reducing the likelihood of recurrence.

CO2 laser finishing can play a particularly important role in the following situations:

-When the lesion's borders are unclear, it feels spread out upon touching, or for individuals with weakened immunity (due to stress, sleep deprivation, etc.)

-When there is a history of warts recurring multiple times

-When lesions are located in frequently touched or easily spread areas such as the hands or face

Milia are small, white, cyst-like lesions that occur when keratin, a type of protein, becomes trapped in tiny pockets beneath the skin. They typically appear around the eyes, on the cheeks, and forehead, and unlike sebaceous cysts, they are considered a cosmetic concern unrelated to inflammation or infection.

Erbium YAG laser is suitable for milia removal. It precisely ablates the skin surface to open the thin epidermal layer of the milia, creating a channel for the safely trapped keratin to be expelled. Subsequently, a gentle cauterization with a CO2 laser as a finishing step can help reduce the possibility of remaining keratinocytes proliferating, thereby preventing milia from recurring in the same area. However, excessive thermal damage to the skin can lead to hyperpigmentation, so precise intensity control by medical staff is necessary.

CO2 laser finishing can be particularly useful in the following cases:

-When milia frequently recur in the same location

-When there is a history of lesions reappearing during the recovery process after previous treatment

-When expecting an even skin condition during recovery after removing multiple milia

Syringomas are benign lesions caused by the excessive proliferation of sweat gland (eccrine gland) tissue in the dermal layer of the skin. They typically appear as small, bead-like, multiple skin lesions on areas such as under the eyes, cheeks, and forehead. They can have a genetic predisposition or are commonly observed in women in their 20s and 30s.

The Erbium YAG laser, due to its ability to delicately and thinly remove the skin surface, can be utilized for treating syringomas in sensitive areas like around the eyes. By refining the skin and removing the upper portion of the sweat gland lesions, it allows for good cosmetic results with minimal scarring or hyperpigmentation after recovery. Subsequently, applying heat with a CO2 laser

to provide subtle thermal stimulation to the deeper parts of the lesion can reduce the activity of the eccrine glands within the dermis, and

can clinically help prevent syringomas from reappearing in the same area. However, due to the depth of the lesions, multiple treatment sessions may be required.

In the following cases, incorporating a CO2 laser finishing touch can further improve post-treatment results:

-When multiple syringomas are relatively deeply embedded under the eyes or on the cheeks, etc.

-When there is a history of lesions recurring despite multiple previous laser treatments

-When aiming for maximum recurrence prevention effect with a single session

Skin tags are benign lesions caused by the excessive proliferation of fibrous tissue and blood vessels in the dermal layer. They commonly appear as small, skin-colored, raised growths in skin folds such as the neck, armpits, under the breasts, and on the eyelids. They are usually painless but can be irritated by friction. Generally, CO2 lasers are known to be more suitable for skin tag removal, as their excellent cutting and hemostatic effects allow for quick removal of multiple lesions. However, for small and thin skin tags, precisely ablating the lesion first with an Erbium YAG laser, followed by finishing cauterization of the lesion's base with a CO2 laser, can help treat the root tissue of the skin tag, reducing the likelihood of recurrence in that area. Thermal stimulation can affect fibrous cells and micro-vessels within the tissue, contributing to inhibiting a re-proliferation environment.

Combining CO2 laser finishing is particularly beneficial in the following cases:

-When skin tags are located in areas prone to friction, such as the neck or armpits

-When there is a history of skin tags reappearing in the same area after removal

-When the lesion's root is deep or wide (the type where the skin remains thick after removal)

Thus, by considering the depth and characteristics of the lesion,

using two types of lasers together,

this 'Dual Laser Treatment Method'

can contribute to enhancing the completeness of the treatment.

After mole removal, how long should DuoDERM (sticker) be kept on?

Since mole removal procedures involve minor stimulation of the skin's surface, they can cause small changes to the skin.

After the procedure, it is important to protect and care for the treated area well.

Maintaining a moist environment, especially preventing the treated area from drying out, can help promote faster recovery and reduce the likelihood of scarring.

Therefore, you might consider using Duoderm, a hydrocolloid moist dressing.

Duoderm helps maintain a moist environment for the wound, allowing skin cells to regenerate naturally and preventing scab formation, thereby minimizing traces of the procedure on the treated area.

It is recommended to apply Duoderm immediately after mole removal, change it every 3-5 days, and consistently manage the area for at least 7 days.

A total management period of approximately 10 days can be considered.

If you have difficulty using Duoderm or experience an allergic reaction, other management methods can be used. In this case, it's advisable to consistently apply a regenerating cream or moist gel to prevent the skin from drying out, and to diligently use sunscreen with an SPF of 50 or higher. Additionally, it is important not to touch the treated area.

Post-care after mole removal goes beyond simply protecting the treated area; it can significantly influence the procedure's outcome.

Insufficient care can lead to traces remaining on the treated area, so continuous attention and management are necessary even after the procedure.

We provide detailed explanations of post-procedure care methods to help those who have undergone treatment recover healthily.
