Introduction

South Korea is one of the world’s most advanced destinations for cosmetic dermatology, attracting international patients seeking innovative treatments, skilled dermatologists, and personalized skincare solutions. Korean skin clinics provide a wide range of procedures, including laser treatments, Botox, fillers, Rejuran, skin boosters, RF Microneedling, Thermage FLX, Ultherapy, and acne scar treatments.

Before starting any new cosmetic procedure in Korea, patients are often asked about their previous aesthetic treatments. Some visitors may think older procedures are no longer relevant, especially if they were performed months or years ago. However, sharing your complete cosmetic history is an important part of receiving safe and effective care.

Previous treatments can influence how your skin responds, which procedures are suitable, and how your dermatologist plans your treatment. By providing accurate information about past cosmetic procedures, you help your Korean clinic create a safer and more personalized approach for your skin.

This guide explains why you should inform Korean skin clinics about previous cosmetic treatments and how this information can improve your overall treatment experience.

Surgical history can affect anatomy and treatment planning.
