Buy for the step, not the hype.
Three complete sets: everything you need for the 4-week plan, and nothing you do not. What changes between $50 and $200 is texture, finish, and how many concerns you treat at once — not whether it works.

Do not buy everything on day one.
New to this: start with the $50 set, then add the toner and a serum in week 2 or 3 — that becomes the $100 set. The $200 set is for people who already know their skin and want the full method from the start.
On Amazon, buy from the official brand storefront only. Third-party sellers sometimes carry counterfeit or expired K-beauty products. Target, Ulta, Sephora, and the brands’ own stores are the safe route.
