Melasma is a chronic pigmentation disorder often triggered by sun exposure, hormonal changes, and genetic factors. However, medications can also play a surprising and often overlooked role in either triggering or worsening melasma. If you’re planning to seek treatment at a Korean dermatology clinic, it’s crucial to discuss your current and past medications with your dermatologist as part of your personalized treatment plan.
This guide explores how medications can affect melasma and what Korean dermatologists recommend patients should communicate during consultations.
🧬 The Link Between Melasma and Medication
Certain medications are known to influence melanogenesis (melanin production) or lead to photosensitivity, both of which can cause or worsen melasma.
Common Medication-Related Triggers:
| Medication Class | How It Affects Melasma |
|---|---|
| Hormonal drugs (oral contraceptives, HRT) | Stimulates melanocytes, especially in women with hormonal sensitivity |
| Antiseizure medications (e.g., phenytoin) | Can lead to pigmentation changes through melanin stimulation |
| Photosensitizing drugs (e.g., tetracyclines, NSAIDs, sulfonamides) | Increase skin sensitivity to UV light, promoting pigmentation |
| Chemotherapy agents | May lead to diffuse or patchy hyperpigmentation |
| Targeted therapies or immunomodulators | Can trigger immune-related pigmentation shifts |
| Antimalarials (hydroxychloroquine) | Rare, but linked to hyperpigmentation in some patients |
| Topical or systemic corticosteroids (overuse) | May thin skin and worsen post-inflammatory pigmentation after withdrawal |
📌 Korean dermatologists prioritize a full medication review before initiating treatment, especially when melasma appears suddenly or is resistant to standard protocols.
🧾 What to Share with Your Korean Dermatologist
During your first consultation at a Korean clinic, you should prepare to discuss:
✅ 1. Current Medications
Include:
- Prescription drugs
- Over-the-counter medications
- Herbal or traditional supplements (e.g., ginseng, red ginseng, dong quai)
- Oral contraceptives or hormone replacement therapy
💬 Tip: Bring a written list or photo of the labels if you’re unsure of exact names or ingredients.
✅ 2. Past Medical Conditions
Certain conditions often treated with melasma-aggravating drugs include:
- Epilepsy
- Endometriosis or PCOS
- Autoimmune diseases
- Chronic inflammation or joint pain
Korean dermatologists will assess how your skin responded during periods of medication use and whether there’s a temporal relationship between drug intake and pigment changes.
✅ 3. Photosensitivity History
If you’ve ever had:
- Rashes or burns after sun exposure
- Unusual skin darkening after antibiotics or painkillers
- Worsening pigmentation during summer months
This may indicate you’re sensitive to UV-reactive medications — something Korean clinics take into account when designing laser and light-based treatment plans.
🧑⚕️ How Korean Clinics Adjust Treatment Plans for Medicated Patients
Korean dermatologists focus heavily on customizing melasma care, especially when medication is a complicating factor.
🔄 1. Coordination With Your Prescribing Doctor
If your medication (like birth control or phenytoin) is suspected as a trigger, your dermatologist may:
- Recommend switching to an alternative (with clearance from your primary doctor or OBGYN)
- Postpone aggressive laser treatment until medication is stabilized
- Prescribe melanin-suppressing topicals to manage pigmentation without interrupting vital medication
💡 2. Non-Laser Approaches
If your medication increases photosensitivity, your Korean dermatologist may recommend:
- Tranexamic acid creams or microinjections (safe for long-term use)
- Azelaic acid or niacinamide to minimize pigmentation risk
- LED red light therapy instead of IPL or high-energy laser
- Barrier-repair creams to build resilience before starting treatment
These conservative approaches reduce the chance of rebound pigmentation or skin sensitivity.
🌤 3. Emphasis on Photoprotection
Patients on photosensitizing drugs receive strict sun protection counseling:
- Physical sunscreen with SPF 50+/PA++++
- Broad-brimmed hats and UPF-rated clothing
- Avoidance of peak UV hours (10 a.m.–3 p.m.)
- Reapplication of sunscreen every 2–3 hours
Some Korean clinics also recommend oral antioxidants or photoprotectants, such as Polypodium leucotomos, to patients on long-term sun-sensitive drugs.
🧪 Are Oral Melasma Medications Safe for Everyone?
In Korea, oral tranexamic acid (TXA) is frequently prescribed for melasma — but it may not be suitable if you are on certain medications or have underlying conditions:
| Condition or Medication | Risk |
|---|---|
| Blood thinners (e.g., warfarin) | Increased clotting risk |
| History of stroke or DVT | TXA may be contraindicated |
| Birth control pills | Combined use with TXA may raise clotting risk |
| Hormone therapy | May increase pigment stimulation |
📌 Always disclose your full medical history before starting oral TXA. Many Korean clinics will perform basic blood work to screen for clotting disorders before prescribing.
🏥 Real Case: Korean Dermatologist’s Approach
Patient: 35-year-old woman with melasma and a 2-year history of oral contraceptive use.
Clinic (Gangnam, Seoul):
- VISIA scan confirmed mixed-type melasma
- Patient history revealed pigmentation began 6 months after starting the pill
- Dermatologist advised switching to non-hormonal contraception (in consultation with OBGYN)
- Started tranexamic acid cream + niacinamide
- After 6 weeks, added low-fluence laser toning
- Patient maintained with sun protection and barrier care
Result: 50% improvement in pigmentation after 3 months, no relapse over 6-month follow-up.

🗣 What Korean Dermatologists Say
“Medications can quietly trigger melasma or make treatment harder. We must approach each case with total awareness of what’s going on inside the body, not just the skin.”
