Serum collection pages should explain the job each serum does

Most users are not searching for serum as an abstract category. They are searching for outcomes like glow, pores, dark spots, or oil control.

Explain which serum type fits which concern, then move users quickly into PDPs and related routine pages.

Serums are high-signal products for both SEO and commerce because they connect naturally to ingredient pages and concern clusters.

Vitamin C, niacinamide, dark spots, oily skin, and personalized routines all belong in the serum cluster.
