What it is

Cryotherapy lesion removal is a dermatological procedure that uses extremely cold liquid nitrogen to freeze and destroy abnormal or unwanted skin tissue. The freezing causes the targeted cells to crystallize and break apart, after which the lesion naturally falls off or heals.

Cryotherapy is commonly used in Korea to treat:

• Warts (caused by HPV)
• Skin tags (acrochordons)
• Seborrheic keratoses (age-related skin growths)
• Actinic keratoses (precancerous lesions from sun damage)
• Some superficial moles or benign growths

💡 In Korea, cryotherapy is often offered as a quick outpatient treatment that can be done alongside mole removal, acne scar care, or pigmentation treatments.

Why it’s done

Cryotherapy is chosen for its speed, effectiveness, and simplicity:

✔ To eliminate warts and viral lesions quickly
✔ To remove benign skin growths with minimal tools
✔ To treat precancerous lesions and prevent progression
✔ To improve cosmetic appearance by clearing rough patches or raised spots
✔ To avoid surgery for small, superficial lesions

Alternatives

If cryotherapy isn’t suitable, alternatives include:

➡️ Electrocautery – Burns off lesions with heat.
➡️ Laser removal (CO₂, Er:YAG) – Vaporizes tissue with precision.
➡️ Surgical excision – For larger or deeper lesions requiring complete removal.
➡️ Topical treatments – Wart acids or prescription creams.
➡️ Observation – If lesion is harmless and not bothersome.

Korean dermatologists often recommend cryotherapy for warts and keratoses, and laser or excision for moles.

Preparation

Before cryotherapy in Korea:

• 🔹 Dermatology consultation → To confirm diagnosis and ensure lesion is suitable for freezing.
• 🔹 Medical review → Patients with poor circulation, diabetes, or certain skin sensitivities may need alternative options.
• 🔹 Pre-care → No special preparation, but area should be clean.

How it’s Done

Cryotherapy is a quick and simple in-clinic procedure:

1. Cleansing → Target area disinfected.
2. Liquid nitrogen application → Applied with a cotton swab or spray device directly onto the lesion.
3. Freezing → Nitrogen freezes tissue, turning it white for several seconds.
4. Thawing cycle → Tissue thaws naturally, and sometimes multiple freeze–thaw cycles are repeated for stubborn lesions.
5. Aftercare dressing → Ointment or protective patch applied if necessary.

⏳ Duration: 5–15 minutes
📅 Sessions: Usually 1–3 treatments depending on lesion type and size

Recovery

Recovery from cryotherapy is straightforward:

➡️ First hours → Tingling, redness, or mild stinging at the site.
➡️ 1–2 days → A blister or scab may form.
➡️ 1–2 weeks → Lesion falls off naturally as skin heals.
➡️ Post-care in Korea:

• Keep area clean and dry.
• Apply ointment as directed.
• Avoid scratching or picking scabs.
• Use sunscreen to prevent pigmentation.

Korean clinics often add LED healing sessions, cooling gels, or scar-prevention creams for smooth recovery.

Complications

Cryotherapy is safe, but minor side effects can occur:

⚠ Possible risks:

• Temporary redness, swelling, or blistering
• Mild pain or stinging during freezing
• Pigmentation changes (light or dark spots)
• Small scar if lesion was deep
• Rare infection if wound is not cared for properly

Korean dermatologists minimize risks with controlled application and follow-up skin management.

Treatment Options in Korea

Cryotherapy is widely available in dermatology clinics across Korea, often part of comprehensive skin-clearing packages.

🇰🇷 Popular Korean Approaches:

• Cryotherapy for warts → Highly effective against viral lesions.
• Cryotherapy for seborrheic keratoses → Common anti-aging treatment.
• Cryotherapy + electrocautery combo → For stubborn or multiple lesions.
• Cryotherapy with scar care → Brightening creams, LED therapy, or hydrocolloid patches.
• K-beauty integration → Patients often receive topical recovery products to prevent pigmentation.

✅ Final Thoughts

Cryotherapy lesion removal in Korea is a fast, effective, and minimally invasive way to clear warts, skin tags, and benign growths. It works by freezing tissue until it naturally detaches, offering a low-risk solution with minimal downtime.

With Korea’s advanced dermatology expertise and scar-focused aftercare, cryotherapy is not only safe but also cosmetically refined, ensuring smooth, clear skin.
