Serums and essences are where Korean skincare does its most targeted work. This collection includes more than 60 formulas organized by concern: brightening (niacinamide, vitamin C), firming (collagen, peptides, PDRN), hydration (hyaluronic acid, beta-glucan), and soothing (centella, heartleaf).

An essence is lighter and used right after toner to prep skin; a serum is more concentrated and targets a specific concern. Many Korean routines use both. Start with one active at a time, patch test, and pair with sunscreen in the morning.

Brands include IOPE, COSRX, Torriden, Fortheskin, Celimax, and more, each with ingredient highlights and how-to-use guidance.

Every product is 100% authentic, sourced directly in Korea, and ships free to the US and worldwide from THE MARO SHOP.
