Building a routine that you will actually keep

The Korean routine got exported as a step count, which is the least interesting thing about it. What actually distinguishes it is sequencing and texture: thin to thick, water-phase before oil-phase, with a genuinely hydrating layer underneath the occlusive one rather than a single heavy cream doing every job at once. That structure is why Korean routines feel comfortable at a level of moisturisation that a single Western cream would feel greasy delivering.

A working routine has four jobs in the evening (remove, hydrate, treat, seal) and three in the morning, since treatment mostly belongs at night and the morning's job is to protect what the night built. Every extra step should be earning its place against a specific thing your skin is doing. If you cannot say what a product in your routine is for, it is not for anything.

The single most common mistake is running a routine designed for a problem you no longer have. Skin changes with season, with hormonal cycle, with what you have been putting on it for the last month. A routine is a hypothesis you keep testing, not a purchase you make once.
