Kkeuthan Clinic's Dual Laser Technique

*Moles are lesions that occur when melanocytes proliferate excessively in the epidermis or dermis.

Although they may appear to be simple pigmentation on the surface, the treatment approach varies depending on their location and depth.

The Er:YAG laser specializes in precise and shallow ablation, allowing for the natural removal of superficial moles located in the epidermis without damaging the skin.

Additionally, it minimizes scarring and offers excellent cosmetic results, making it particularly effective for mole removal on the face. Subsequently, the process of using a CO2 laser to thermally ablate the base of the mole helps reduce the recurrence rate by destroying melanocytes that may remain in deeper layers. This diminishes the possibility of 'recurrent moles' where the surface is removed but the root remains and regenerates.

CO2 laser finishing is highly recommended in the following cases:

-If the mole is slightly raised or feels plump when pressed

-If there is a history of mole recurrence in the same area

-If it is identified as a deep dermal nevus (e.g., blue moles, grayish-brown moles, etc.)

*Flat warts are viral skin lesions caused by human papillomavirus (HPV) infection. They spread within the epidermis and appear as thin, widely spread, small brown or flesh-colored lesions to the naked eye. They often develop when immunity is weakened and can spread through self-contact, making early treatment crucial.

The Er:YAG laser is effective in evenly ablating the epidermal layer, making it useful for extensive flat warts,

as it can treat them all at once. It can uniformly remove lesions while minimizing skin damage. However, due to the nature of viral lesions, there's a risk of recurrence if only the surface lesions are removed. In such cases, the finishing process of applying thermal damage to the surrounding area with a CO2 laser can be a clinically significant treatment to reduce recurrence rates by additionally ablating virus-infected cells that may remain in the epidermis and its vicinity.

CO2 laser finishing is particularly important in the following cases:

-If the lesion's border is unclear or feels flat and spread out when touched, or for individuals with weakened immunity (due to stress, sleep deprivation, etc.)

-If there has been a history of multiple recurrences

-If the lesion is located in an area prone to frequent contact or spread, such as the hands or face

*Milia are lesions that appear as small, white cysts when keratin (a type of skin protein) becomes trapped within the skin. They commonly occur around the eyes, on the cheeks, and forehead, and unlike sebaceous cysts, they are cosmetic lesions unrelated to infection or inflammation.

The Er:YAG laser is highly suitable for milia removal. It precisely ablates the skin surface to remove the thin epidermal layer of the milium and opens a pathway for the safe discharge of trapped keratin. A gentle finishing ablation with a CO2 laser afterwards helps reduce the possibility of remaining keratinocytes proliferating and prevents milia from repeatedly forming in the same area. However, precise intensity control is necessary, as excessive thermal damage to the skin can lead to post-inflammatory hyperpigmentation.

CO2 laser finishing is particularly beneficial in the following cases:

-When milia repeatedly appear in the same location

-If there has been a history of lesions protruding again during regeneration after treatment

-When aiming for uniform results during the regeneration process after removing multiple milia

*Syringomas are benign lesions formed by the excessive proliferation of sweat glands (eccrine glands) within the dermis. They are characterized by multiple small, bead-like skin lesions that can be felt under the eyes, on the cheeks, and forehead. They are particularly common in individuals with genetic factors or women in their 20s and 30s.

The Er:YAG laser is suitable for treating syringomas in sensitive areas like the periorbital region because it can remove the epidermis thinly and precisely. It refines the skin surface and removes the upper part of the sweat gland lesions, resulting in minimal scarring or pigmentation during recovery, which is excellent from a cosmetic perspective. Subsequently, applying heat with a CO2 laser

in a finishing treatment that creates micro-damage in the deeper parts of the lesion, weakens the activity of sweat glands in the dermis,

and has clinical significance in preventing syringomas from proliferating again in the same area. However, as the lesions are deep, repeated treatments are often necessary.

Combining with CO2 laser finishing improves treatment efficacy in the following cases:

-When multiple syringomas are relatively deeply located under the eyes or on the cheeks

-If recurrence has occurred despite previous multiple laser treatments

-When aiming for maximum recurrence prevention effects with a single treatment

*Skin tags (acrochordons) are benign lesions caused by the excessive proliferation of fibrous tissue and blood vessels in the dermis. They commonly appear in skin folds such as the neck, armpits, under the breasts, and on the eyelids, presenting as small, flesh-colored, raised lesions. While generally painless, they can become irritated by friction. Typically, CO2 lasers are more suitable for skin tag excision due to their superior cutting and hemostatic effects, allowing for rapid removal of multiple lesions. However, for small and thin skin tags, precisely ablating the lesion with an Er:YAG laser first, followed by a finishing thermal ablation of the lesion's base with a CO2 laser, helps remove the entire root tissue of the skin tag and lowers the possibility of recurrence in that area. Thermal stimulation has the effect of destroying fibrous cells and microvessels within the tissue, inhibiting the regenerative environment.

It is highly recommended to combine with CO2 laser finishing in the following cases:

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

-If there is a history of skin tags recurring in the same area after excision

-If the lesion has deep and wide roots (the type that leaves a raised mark even after excision)

Thus, depending on the depth and nature of the lesion,

combining two types of lasers

the 'Dual Laser Technique'

is a key strategy for enhancing the completeness of treatment.

After mole removal, how long should I keep the DuoDERM (sticker) on?

Mole removal procedures involve a process that removes the surface layer of the skin, leading to physical damage.

Due to this, it is crucial to properly protect and care for the treated area.

In particular, keeping the treated area moist significantly impacts the speed of recovery and scar prevention.

For this purpose, the application of DuoDERM, a hydrocolloid dressing, is recommended.

DuoDERM keeps the wound moist to promote cell regeneration and delays scab formation, thereby reducing the likelihood of scarring.

Ideally, DuoDERM should be applied immediately after mole removal, replaced every 3-5 days, and used for at least 7 days.

A total care period of about 10 days is recommended.

If DuoDERM use is difficult or an allergy occurs, you should manage the area by frequently applying a regenerating cream or moisturizing gel to prevent dryness, rigorously using sunscreen with SPF 50 or higher, and avoiding touching the wound.

Post-mole removal care goes beyond simply protecting the wound; it is a crucial process that determines the final outcome.

Neglecting aftercare can lead to scars, so continuous attention is required even after the procedure.
