Some of the most talked-about serums don't make this ranking. That isn't because the experts dislike them: every one of these has fans. They just drew more reservations than the serums that made the cut, where last place holds a Guru Score of 75%. Here is what holds each one back.

A Guru Score of 59% from 16 experts.
The catch: Intense stinging and burning sensation for some

A Guru Score of 64% from 15 experts.
The catch: Pricey for what it does

A Guru Score of 67% from 14 experts.
The catch: Requires consistent use five times weekly

A Guru Score of 71% from 14 experts.
The reservation, in No BS Beauty's words:

Ranked from the public takes of 42 independent gurus, including 14 dermatologists, 3 makeup artists and 3 beauty journalists.
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.
On the latest data it is The Ordinary Multi-Peptide + Copper Peptides 1% Serum, with a Guru Score of 88% from 21 gurus. The ranking above lists all 25 that clear our bar, in order.
Of the 14 dermatologists whose reviews feed this ranking, more approve of SkinCeuticals C E Ferulic than any other pick: 11 of them. It holds a Guru Score of 77%, at number 22 on the list. Next comes The Ordinary Multi-Peptide + Copper Peptides 1% Serum, with 9.
SkinCeuticals C E Ferulic: 34 gurus have weighed in on it, more than any other pick here, and it holds a Guru Score of 77%, at number 22 on the list.
Of the 21 we hold a full ingredient list for, 19 skip drying alcohol, 17 are fragrance-free, 17 contain hyaluronic acid and 15 contain peptides. That is a pattern in what the experts rate, not a rule: the ranking itself is by their verdicts.
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.
