Dealing with recurring breakouts? In Korean dermatology, the approach is different from what you’d expect

Many people think acne treatment is just “pop and apply cream”. But in a proper Korean dermatology clinic, acne care follows a staged, type‑based system. If you’re struggling with closed comedones, inflammatory papules, cysts, or worrying about leftover scars and dark marks, this article can help you get your bearings – no fear‑mongering, just facts.

First things first: Acne is not “excess heat” – it’s chronic inflammation of the pilosebaceous unit

The root of acne lies in abnormal follicular keratinisation, excess sebum production, and proliferation of Cutibacterium acnes – together driving inflammation. Korean dermatologists typically assess severity (mild, moderate, severe) and then map out a step‑wise plan. The goal is not “immediate disappearance”, but controlling inflammation, reducing recurrence, and preventing scars.

Three main routes – which one fits you?

Common approaches in Korean clinics fall into three broad categories: topical/oral medications, light‑based/laser therapies, and chemical peels. In many cases, they are combined.

① Pharmacotherapy (foundational)

• Topical retinoids (e.g., adapalene, tazarotene): Improve follicular keratinisation, especially effective for closed comedones. Typically used for 8‑12 weeks; initial peeling and dryness are common.
• Benzoyl peroxide: Antibacterial and anti‑inflammatory, works well for inflammatory lesions but may cause irritation.
• Oral antibiotics (e.g., doxycycline, minocycline): Used for moderate‑to‑severe inflammatory acne; course usually 6‑8 weeks, under medical supervision.
• Oral isotretinoin (Roaccutane): The most effective treatment for severe nodulocystic acne, but with significant side effects (dry skin/mucosa, elevated lipids, teratogenicity). Must be closely monitored by a doctor.

② Light & laser therapies (advanced)

• Intense Pulsed Light (IPL): Targets post‑inflammatory erythema (red marks) by photothermolysis of blood vessels; typically 3‑5 sessions per course.
• Pulsed Dye Laser (PDL): Specifically targets vascular redness – more precise than IPL.
• Non‑ablative fractional laser (e.g., 1550nm): Stimulates dermal collagen regeneration, improving shallow scars and enlarged pores.
• Ablative fractional laser (e.g., CO₂): For deeper scars – more traumatic with longer downtime, but more effective.
• Blue/red light therapy: Blue light kills bacteria, red light reduces inflammation – suitable for mild‑to‑moderate inflammatory acne as an adjunct.

③ Chemical peels (adjunctive)

• Alpha‑hydroxy acids (glycolic, mandelic): Improve comedones and superficial marks; concentrations range from 20% to 70%, requiring multiple sessions.
• Salicylic acid: Lipophilic, penetrates follicles – good for blackheads and whiteheads.
• Combination peels: Blend multiple acids for both exfoliation and anti‑inflammatory effects.

Real cost to your wallet – how much in KRW?

Total cost depends on the combination of modalities. Here are approximate package ranges (all in KRW):

• Mild acne (topicals + red/blue light): ~100,000‑180,000 KRW per combined session; course of 5 sessions totals ~400,000‑700,000 KRW.
• Moderate acne (oral antibiotics + IPL): monthly medication ~30,000‑80,000 KRW; IPL ~200,000 KRW/session; a 3‑session course ~600,000 KRW.
• Severe acne (isotretinoin + fractional laser combination): monthly medication ~150,000 KRW; fractional laser ~500,000‑800,000 KRW/session – total can be high and needs individual assessment.
• Standalone chemical peels: ~80,000‑200,000 KRW/session; course of 4‑6 sessions totals ~350,000‑900,000 KRW.

Don’t just look at the results – these trade‑offs are real

All treatments carry potential side effects. Knowing them objectively helps you prepare.

Medication‑related

• Topical retinoids: initial dryness, peeling, redness – requires a build‑up phase (2‑4 weeks).
• Oral antibiotics: may cause GI upset, vaginal candidiasis – consider probiotics.
• Isotretinoin: chapped lips, dry skin, elevated lipids, liver enzyme changes – women of childbearing age must use strict contraception (high teratogenicity). Monthly blood tests are mandatory.

Light / laser‑related

• IPL/PDL: transient redness, purpura (common with PDL) – resolves within 1 week. Rarely, blisters or hyperpigmentation.
• Non‑ablative fractional: redness, heat sensation – subsides in 3‑5 days. Temporary hyperpigmentation possible (especially in darker skin).
• Ablative fractional: significant pain – requires topical or injectable anaesthesia. Post‑op crusting, oozing, recovery 7‑14 days – risk of infection, scarring, pigment changes.

Chemical peels

• AHA/BHA: mild stinging, peeling; occasional “purging” (expulsion of follicular contents) – usually resolves in days.

After treatment – things you must avoid

• During topical therapy: Strict sun protection (physical blockers preferred); avoid combining with other irritants (e.g., scrubs, retinol).
• After laser/ablative procedures: Ice packs for 48 hours, keep wounds clean and dry, apply prescribed ointments. Avoid makeup, swimming, saunas for 7 days. Sun protection is paramount – continue for at least 1 month.
• After chemical peels: No water contact for 24 hours, avoid rubbing for 3 days, use gentle moisturisers, stay away from heat.
• During oral isotretinoin: Use lip balm and artificial tears liberally; do not donate blood; contraception continues for at least 1 month after stopping.
