Enlarged Pore Treatment in Seoul – Diagnosis by Board-Certified Dermatologists
Enlarged pores are visibly wide follicle openings, usually on the nose, cheeks and forehead, caused by oil production, loss of skin elasticity, sun damage and genetics. At The Heal Dermatology Sinsa Main Branch in Gangnam, Seoul, board-certified dermatologists assess the cause and may recommend microneedle RF, skin boosters, peels or skin Botox to make pores look smaller.

What causes enlarged pores
Pores look larger when oil glands are active, when pores are filled with sebum and debris, and when collagen around them weakens with age and sun exposure. Genetics and skin type play a large role. Humidity, heat and heavy, occlusive cosmetics can make pores look more prominent during the day. Pores cannot be closed, but their appearance can usually be reduced with consistent care.
How a dermatologist diagnoses it
A dermatologist evaluates skin type, oiliness, texture and sagging, often with imaging-based skin analysis. They distinguish oil-related pores from elasticity-related or scar-related pores, because the treatment approach differs.
Treatment options at The Heal Sinsa
Options include Potenza or Sylfirm X microneedle RF, skin Botox to reduce oil, skin boosters, aqua peel and chemical peels. Availability of specific devices varies by branch – confirm at consultation. Every plan starts with a 1:1 consultation with a Korean board-certified dermatologist and imaging-based skin analysis; you will not be pushed toward treatment you do not need. Pricing is confirmed after consultation; see pricing and payment.
Sessions, downtime & side effects
- Microneedle RF: usually three to five sessions, redness for one to three days
- Skin Botox effects typically last about three to four months
- Peels: minimal downtime, often repeated every 2–4 weeks
- Risks include temporary redness, swelling, pinpoint marks or breakouts
Home care
Cleanse gently twice daily, use oil-free moisturiser and daily sunscreen, and consider products with retinoids, niacinamide or salicylic acid introduced gradually. Avoid pore strips and aggressive scrubbing, which irritate skin.
When to see a doctor
See a dermatologist if pores come with persistent breakouts, blackheads that do not respond to home care, or textured scars, or if home products irritate your skin.
Planning around your trip to Seoul
Microneedle RF redness usually settles within a few days, so plan it before sightseeing days. Our Korean skin analysis guide explains the imaging step. The clinic is on the 7th floor of Sinsa Square near Sinsa Station, close to Garosu-gil (getting here), and English support is available on request (international patients).

Frequently asked questions
Can pores be permanently shrunk?
Pores cannot be closed or permanently removed, but treatments that reduce oil and strengthen surrounding collagen can make them look noticeably smaller. Maintenance is usually needed because ageing and oil production continue.
What helps oily skin with large pores?
Gentle cleansing, lightweight moisturiser, sunscreen and ingredients like niacinamide or retinoids can help. In clinic, skin Botox and microneedle RF are common options. A dermatologist will match treatment to your skin type.
Do pore treatments have downtime?
Most have little. Peels and skin boosters usually cause mild redness for hours, while microneedle RF may cause redness and swelling for one to three days. Your dermatologist will explain what to expect for your plan.
