Laser Removal for Protruding Lesions such as Skin Tags, Milia, Seborrheic Keratosis, and Warts

KKEUT Clinic — Dual Laser Technique

Not every spot or bump is the same. We combine Er:YAG and CO₂ lasers according to lesion depth and type to improve cosmetic outcomes and lower recurrence.

Moles (Nevi)

A “mole” forms when melanocytes proliferate in the epidermis or dermis. Because depth varies, the approach must match location & depth.

• Er:YAG laser: ideal for precise, superficial planing of epidermal, shallow moles, smoothing the surface with minimal thermal injury—excellent for the face.

• CO₂ laser finishing (coagulation): gently heats the mole base to destroy residual melanocytes in deeper layers, reducing regrowth.

CO₂ finishing is especially helpful when:

• The lesion is slightly raised or feels thick on pressure

• There’s a history of regrowth at the same site

• It appears to be a deeper dermal nevus (e.g., blue/gray-brown)

Flat Warts (Verruca plana)

Caused by HPV, these spread within the epidermis as thin, flat, skin-colored/light-brown papules. They may worsen with lowered immunity and can spread by self-contact, so early care matters.

• Er:YAG: evenly resurfaces the epidermis to clear widespread, thin lesions with minimal collateral damage.

• CO₂ finishing: treats margins with controlled heat to target remaining infected cells and lower recurrence.

CO₂ finishing is key when:

• Borders are indistinct or feel diffusely spread

• Immunity is reduced (stress, poor sleep, etc.)

• Lesions are on hands/face—areas prone to contact and spread

Milia

Small white cysts where keratin is trapped under thin skin (often eyelids, cheeks, forehead). Cosmetic, not inflammatory.

• Er:YAG: precisely opens the thin epidermal roof to release keratin safely.

• Light CO₂ finishing: discourages keratin-cell regrowth to reduce recurrence.

Excess heat can cause post-inflammatory hyperpigmentation, so fine parameter control is essential.

CO₂ finishing helps when:

• The same spot keeps forming milia

• A lesion re-bulges during healing after prior removal

• Multiple milia are treated and a uniform outcome is desired

Syringomas

Benign overgrowth of eccrine sweat glands in the dermis, often multiple under the eyes, cheeks, or forehead (sometimes familial; common in women in their 20s–30s).

• Er:YAG: delicately removes the overlying epidermis, ideal for sensitive peri-orbital skin with low scar/PIH risk.

• CO₂ finishing: applies micro-thermal impact to the deeper gland portion to weaken activity and lower regrowth.

Because they sit deep, repeat sessions are often required.

CO₂ finishing is valuable when:

• Many lesions sit deeper under the eyes/cheeks

• There’s recurrence after prior laser treatments

• You want to maximize recurrence prevention in one course

Skin Tags (Acrochordons)

Benign overgrowths of fibrous tissue and vessels on neck, underarms, inframammary area, eyelids. Painless but easily irritated by friction.

• CO₂ laser typically excels at fast cutting and hemostasis for multiple tags.

• For small, thin tags, we may plane with Er:YAG first, then CO₂-coagulate the base to treat the root and lower recurrence, as heat disrupts fibroblasts and microvasculature that support regrowth.

CO₂ finishing is recommended when:

• Tags are in high-friction zones (neck, axillae)

• There’s a history of regrowth

• The stalk/base is deep or broad

Bottom line: Matching lesion depth and biology with an Er:YAG + CO₂ plan is a key strategy to optimize cosmetic healing and reduce recurrence.

After Mole Removal — How Long to Wear DuoDERM®?

Mole removal resurfaces the skin, creating a controlled wound. Moist wound care speeds healing and helps reduce scarring.

• Apply DuoDERM® (hydrocolloid) immediately after treatment and change every 3–5 days.

• Keep it on for at least 7 days; aim for ~10 days total.

• If hydrocolloids don’t suit you or you react to adhesives, use a regenerating cream or moist gel frequently to prevent drying, apply broad-spectrum SPF 50+, and avoid picking.

Proper aftercare directly influences your result—not only protection but scar minimization. KKEUT Clinic provides detailed guidance for faster, healthier healing.

Who Is This For?

1. Anyone concerned about moles, seborrheic keratoses (age spots), milia, syringomas, or skin tags

2. Those with recurrent lesions after prior removal

Treatment Steps

STEP 01. Self-cleansing
STEP 02. Topical numbing cream
STEP 03. Lesion removal (dual-laser plan as indicated)

Aftercare

• Try to keep the site dry (wash with DuoDERM® on).

• During the re-epithelialization phase, keep using regenerating tape/hydrocolloid if possible (~10 days total).

• Some moles may recur; re-treatment is possible from ~4–6 weeks.

• Deep-rooted lesions may need repeat sessions.

• Minimize sun exposure; SPF is essential (apply even over DuoDERM® if exposed).
