Sinsa (신사).

Sinsa-dong borders Apgujeong to the north but has a very different character: younger demographic, more dermatology than surgery, and prices at the lower end of the Gangnam range. The Garosu-gil strip (가로수길) is the main landmark.

Skin-focused procedures dominate Sinsa: laser toning, Rejuran, skin boosters, botox, fillers, thread lifts. Surgery exists but is less concentrated than in Apgujeong or Cheongdam.

First-time visitors to Gangnam who want dermatology without the premium markup, locals who work in the area, and anyone planning a course of treatments (5–10 sessions of laser or skin booster) where small price deltas compound.

Sinsa is typically 5–15% below Gangnam baseline, occasionally lower for promotional packages. It's the cheapest way to access genuinely top-tier Korean dermatology without leaving Gangnam-gu.
