Our verdict
The patches sit at 4.4/5 and the serum at 4.5/5, on review pools of 1,362 and 899, so the gap between the two scores is well inside the noise. The patches are a targeted eye-area product with caffeine, collagen and retinol, listed for combination and normal skin, and flagged as containing actives that can irritate reactive skin, so test one on a less sensitive patch of skin before using them under the eyes. Thirty pairs sounds generous but it is one small area, a few times a week. The PDRN Pink Peptide Serum is 3.71 fl oz, a genuinely large bottle for this price band, covers your whole face, and is listed for dry and sensitive skin as well as combination and normal. For sheer coverage per dollar the serum wins comfortably. The patches only make sense if under-eye puffiness and dark circles are the exact thing you are shopping for.
