I’ve seen laser skin-toning treatments that go between 1 M to 1.2 M that include 3 to 5 sessions. However, all lasers are not created equal and Fractional Laser treatment, which is essentially skin resurfacing might be priced higher. Also, are you OK with the downtime the laser might cause? Your skin will appear like you just had a real bad sun burn with scabbing for the next few days post treatment. It would be essential for you to stay indoors, and apply good sun protection if you do go out. Leaders is also popular, a lot of foreigners living in Korea like to go there because of their communication skills.
After doing some naver searches, renewme and leaders quote does seem high in comparison to smaller clinics that cater to Koreans:
This clinic for instance (Lamar Skin) has this treatment stack (15 total treatments) for 870,000 aprox $800 USD:•3 Fraxel Xena Laser Treatments + 3 Fraxel C02 Laser Treatments + 3 MTS (Microneedle Therapy System) + 3 Cyro Cell Treatments and after 1 week of treatment 3 Skin Rejuvenation Facials
But note that type of treatment package would happen over the course of 3 to 4 months.
FYI (Fraxel is a brand name of the first Fractional laser)
So compared to 870,000 those prices are expensive, but still cheaper than in the US, but you have to factor in your flight and accommodations. Are you coming to Korea for cosmetic medical treatment or for business/vacation?
There tends to be different pricing for foreigners at international clinics, usually because they need to offset their expenses for attracting and servicing foreign patients: staffing, licenses, insurance, taxes and marketing channels (multilingual websites & email).
But walking into a local Korean clinic, although attractive because of pricing, can have very different standards for customer service than an international clinic, and may present a language barrier. Renewme for instance treats foreigners like VIPs and will have someone there to communicate with you in English.
You might also want to checkout Dr Woo & Haan Skin Clinic. They have more of a general hospital feel & approach, and tend to be more pragmatic and transparent in their diagnosis and suggest treatments based on safety and what’s best for the patient. They are the official dermatology hospital for the US military base.
