Preparing for a skin treatment in Seoul requires more than just booking an appointment. Because Korean clinics use advanced, high-intensity technology, your skin needs to be in a "stable" state to achieve the best results and avoid complications.

Two Weeks Before: Sun & Medication Protocol

The primary reason treatments for international visitors are postponed is sun-exposed skin.

• Avoid Tanning: Do not tan or spend long hours in direct sunlight for at least 14 days. Sun-stressed skin is highly reactive to lasers and can lead to burns or permanent dark spots.
• Manage Supplements: Stop taking blood-thinning supplements like Vitamin E, Ginkgo Biloba, or high-dose Omega-3 7 days before your appointment, as these can increase bruising during injectables like Rejuran or Juvelook.
• Check the Calendar: Ensure your visit doesn't fall on a major holiday when clinics close. Keep in mind that Chuseok will see almost all major clinics shut down.

Five Days Before: Simplify Your Routine

Modern Korean lasers are extremely precise. Using harsh products beforehand can make your skin barrier too fragile for the laser to work safely.

• Pause Active Ingredients: Stop using all Retinol, Vitamin C, AHAs (Glycolic Acid), and BHAs (Salicylic Acid).
• Focus on Hydration: Switch to a simple routine. Use gentle cleansers and ceramides to ensure your skin barrier is strong and ready to heal quickly.

The Day of Treatment: The "Clean Slate" Rule

• Go Bare-Faced: While clinics can wash your face for you, arriving without makeup allows for a more accurate AI Skin Analysis.
• Bring Your Physical Passport: Even though the Medical VAT Refund ended on January 1, 2026, your physical passport is still required for medical registration and identification at most professional clinics.
• Eat a Light Meal: Many treatments involve numbing cream or mild sedation. Having a light meal prevents dizziness during the procedure.

Strategic Planning

• The Downtime Window: Plan your appointment for the end of your trip or before a couple of "indoor" activity days. Many skin boosters leave small bumps (embossing) that can last 24–48 hours.
• Document Your History: Have photos of your current skincare products and a list of any treatments you’ve had in the last 6 months ready on your phone.
• Budget for 10% VAT: Remember to factor the 10% VAT into your budget. Since the government refund program is over, the price you see on the menu is usually the "base price" before tax.

Final Pre-Visit Checklist

• Stop using Retinol or chemical exfoliants for 5 days.
• Avoid heavy sun exposure for 14 days.
• Ensure your physical Passport is in your bag.
• Take photos of your current skincare routine.
• Prepare a high-SPF sunscreen for the walk home.
