Korean Skincare Routine for Hot & Humid Climates

Who This Routine Is For

If your skin turns shiny within an hour of leaving the house in summer, this routine was put together with you in mind. It is designed for oily and reactive skin types that struggle in hot, humid conditions — the kind where sweat and sebum combine by midday and pores start looking more visible than usual.

It is also useful if your skin feels generally unbalanced in summer rather than simply dry or simply oily. Heat can tip reactive skin into a cycle of overproduction and irritation, and the steps here address both sides of that: control the oil, but don't strip the skin.

How Koreans Approach Summer Skin

In Korea, summer skincare is its own category. The humidity in cities like Seoul from June through August is significant, and the local market reflects that — lightweight textures, sebum-control formulas, and portable reapplication products fill the seasonal shelves every year. Rather than switching to a stripped-down routine, many people in Korea layer a small number of purposeful steps: something to prep the skin, something to regulate oil through the day, and a sunscreen that won't add to midday congestion. Finishing powders or setting steps are also a practical everyday habit, not a makeup-only move. This routine follows the same logic.

Step 1 — Prep the Skin First

The routine opens with the medicube Zero Pore Pad 2.0, and the order makes sense. After cleansing, residual impurities and surfactants can sit on the surface and contribute to congestion through the day. A swipe of this pad addresses that before any active products go on.

The pad contains lactic acid and salicylic acid, which work at the surface and inside the pore to keep things clear, along with willow bark extract. It also contains several essential oils and alcohol, so patch-test first; if your skin is sensitive, the brand suggests using it once a day or two to three times a week. Using it as the first step means the serum and sun stick that follow are applied to a cleaner, more prepared surface.

Step 2 — Regulate Oil at the Source

The Jumiso Niacinamide 10 Serum is the routine's main active step. It contains niacinamide at a high concentration — 10% — which is formulated to control excess sebum production rather than just blot it away after the fact.

The formula also includes tranexamic acid and glutathione alongside the niacinamide. The texture is lightweight enough to sit comfortably under sunscreen without pilling, which matters when you are building toward a matte finish. This is the step doing the most regulatory work in the routine.

Step 3 — Sunscreen That Works With the Routine, Not Against It

The AHC Masters Icy Jelly Sun Stick closes the active part of the routine with UV protection. The stick format is practical in humid conditions — no liquid to run, no bottle to open on a crowded commute. The formula is described as a cool, matte jelly and includes aloe barbadensis leaf extract and collagen extract. It also contains fragrance and bergamot oil, so patch-test first if your skin reacts to fragrance.
