Best k-beauty serums — full rankings

What to look for in a serum

Serums deliver concentrated actives directly to the skin — the ingredient list matters more here than in any other category.

Active ingredients and position

The higher an active appears on the INCI list, the more of it the formula contains. Niacinamide, retinol, and vitamin C are the most researched actives.

Concentration signals

If an active is listed after preservatives or fragrance, the concentration is likely too low to be effective. Position is everything.

Layering compatibility

Water-based serums layer well under moisturisers. Oil-based serums should go last. Avoid mixing direct acids with retinol in the same routine.

Supporting ingredients

Good serums pair actives with soothing and hydrating ingredients (like panthenol or allantoin) to reduce irritation risk.
