Treating stubborn pigmentation in Korea. Any clinic recommendations?

Hi everyone, I’ve been struggling with pigmentation for a while, mostly sun spots and uneven tone around my cheeks. I’ve tried different skincare products but nothing seems to fully fade it.

Since I’m visiting Seoul soon, I’ve been researching clinics in Gangnam that specialize in pigmentation treatments like laser toning or pico laser. Some of the clinics I’ve looked into so far are Lienjang Clinic, Abijou Clinic, and Delight Dermatology.

For those who have treated pigmentation in Korea, how effective was it? Did you need multiple sessions, and did the results last?

I’m also curious about consultation quality. Did the doctor actually analyze your skin and recommend a plan, or was it more like choosing from a menu of lasers?

Any experiences or clinic recommendations would be really helpful. Thank you!
