[GANADI EDITION] COSRX The 6 Peptide Skin Booster Serum 150ml Double Set (+Random Hipper)

The Gist

The [GANADI EDITION] COSRX The 6 Peptide Skin Booster Serum 150ml Double Set (+Random Hipper) is a thin, water-gel essence designed to prime skin before layering other serums or treatments. It absorbs in seconds without tackiness, making it practical for both morning routines and pre-makeup application. The brand positions it as a synergistic blend of six peptides chosen to address hydration, elasticity, and brightening—though the serum’s real strength, per Korean reviewers, lies in its prep role rather than standalone performance.

What Korean reviewers say

Users with dry or dehydrated skin report meaningful improvements in texture and moisture retention, and many notice that active ingredients perform noticeably better when applied after this serum. However, several reviewers with active breakouts or folliculitis flagged that the product either triggered or exacerbated inflammatory lesions, even when used sparingly—a genuine incompatibility worth testing first if your skin barrier is compromised. Some describe the effect as subtle or unremarkable until they stopped using it; others find the result obvious only when layered consistently. The double-set format offers value, though the 150ml size depletes quickly with repeated layering.

Bottom line

At $32.28 for a double set, this is an affordable hydration layer for dry or winter-stressed skin and a smart addition if you use potent actives. Skip it if you have active acne or a reactive skin barrier, and patch-test before committing.
