Routine conflict checker
Tick the actives you use and get the clashes, the order to apply them and the simplest AM/PM split — the K-beauty way of layering without irritation.
How the verdicts work
Declared conflicts from the library win. Two irritation-class actives (acids, retinoids, strong vitamin C) default to "alternate nights". Everything else is ordered thinnest to thickest, low pH first, oils last.
Then check one pair at a time
Every flagged pair links to its own "can I mix" page with the reasoning and a layering plan, so you can judge the rule rather than just the answer.

What is the 10-step Korean skincare routine?
The 10-step Korean skincare routine is a layered framework popularized in Korea: oil cleanser, water cleanser, exfoliant, toner, essence, serum or ampoule, sheet mask, eye cream, moisturizer and sunscreen. It's a customizable menu, not a daily mandate, and most people use only the steps their skin needs.
What is a good Korean skincare routine for beginners?
A simple beginner Korean routine is a gentle cleanser, a hydrating toner, a lightweight moisturizer and daily sunscreen, adding one targeted serum once your skin adjusts. Introduce actives slowly, one at a time, and patch-test, following the Korean principle of gentle, barrier-friendly care over many steps at once.
How many steps should a Korean skincare routine have?
As few as three: cleanser, moisturiser and sunscreen. The ten-step routine was a Western marketing frame rather than a Korean rule — most Koreans use a handful of products daily and add extras occasionally.
How often should you exfoliate in a Korean routine?
Once or twice a week for most people, up to three times for oily and resilient skin. Frequency matters far more than strength — a mild acid used consistently beats a strong one that forces you to stop.
