These are the 10 serums that the dermatologists and skincare experts we follow rate most highly for oily skin, ranked purely by how warmly they talk about them in their own reviews. No brand pays to appear, and the order updates as new reviews come in.

Every score is the Guru Index consensus across all the gurus who have weighed in, so a single rave can't crown the list: products need enough independent reviews to count. We surface the picks the gurus flag as a good fit for this skin type, but skin is personal, so anything new is best patch-tested first. A Guru Certified mark means broad agreement across many experts; a Top Pick means a guru explicitly named it best in its category.

Who's doing the judging

Ranked from the public takes of 33 independent gurus, including 11 dermatologists, 3 makeup artists and 2 doctors.

These are independent experts we follow, not an in-house panel. We collect opinions they have already shared publicly on YouTube; they are not connected to The Guru Index and have not endorsed this ranking. "Guru" is our own editorial title for the voices we trust.

You asked

Q1

What is the best serum for oily skin?

On the latest data it is Numbuzin No.3 Vitamin Concentrated Serum, with a Guru Score of 87% from 6 gurus. The ranking above lists all 10 that clear our bar, in order.

Q2

How is this ranking decided?

We rank by the Guru Index consensus score: the warmth of every independent expert take we have logged for each product, with a minimum number of reviewers required so a single enthusiastic review can't top the list. Nothing here is paid placement.

Q3

What does Guru Certified mean?

Guru Certified marks a product that a broad group of experts agree on, not just one fan. It is our breadth stamp, distinct from a Top Pick, which is a single guru crowning a product best in its category.

Q4

How often does the list update?

The results refresh every day from the latest expert reviews, so the ranking reflects what the gurus are saying now, not a frozen editor's pick.
