Serum is typically applied on slightly damp skin after toner. This helps with even application and makes the routine feel more comfortable without needing extra product.

Some people layer serums, but many prefer using one at a time to keep routines simple. If using more than one, lighter textures are applied first, followed by slightly heavier ones.

Face serums are usually used once or twice daily depending on the routine. Morning use is often followed by sunscreen, while evening use fits into a simple cleansing routine. Consistency matters more than frequency.
