COSRX's Blue Peptide Bakuchiol Plump Glow Serum page has a solid foundation — clear product naming, a functional image gallery with video, and star ratings near the title — but is held back by three compounding gaps. The strongest dimension is visual merchandising, with a multi-image carousel and video present. The single most critical gap is mobile performance: a 38 PSI score and 13.7-second LCP means the majority of cold mobile visitors will bounce before the page is even usable, making every other optimization on the page irrelevant.
Top Finding
No press mentions, 'As Seen In' bar, or named certifications are visible anywhere on the page. COSRX is a well-known K-beauty brand with significant press coverage, but none of it is surfaced here.
