How to choose an eye product: three practical checks
How to choose an eye product without stopping at “caffeine” or a dark-circle promise? Organise the comparison around three checks: exact identity, formula information and the quantity you want. The linked profiles are examples, not a ranking.

First: is this the eye product?
A range may include face cream, face serum and eye serum. Distinguish 15 ml Hyalu B5 Eye Serum from other Hyalu B5 products. For Clinique, check All About Eyes and the exact variant; for The Ordinary, look for the full Caffeine Solution 5% + EGCG name. The brand alone is not enough.

Second: what does the number describe?
The official Hyalu B5 Eye Serum page describes a 10% complex. We do not turn that into “10% caffeine”: a blend percentage and a single-ingredient percentage are different information. Where the concentration you want is absent, leave it undeclared.

Third: quantity and cost
The selected examples include 30 ml for The Ordinary and 15 ml for Hyalu B5 and Clinique. Compare unit cost without estimating usage time from volume alone. Read directions and consider how much you want to purchase rather than automatically favouring the larger pack.
From comparison to decision
For more detail on serum versus cream, open the dedicated The Ordinary–Clinique comparison. This category guide does not promise to eliminate puffiness or dark circles or identify their causes. Persistent discomfort or problems around the eyes require appropriate professional assessment, not just cosmetic selection.
Frequently asked questions
Does a 10% complex contain 10% of every ingredient?
No. The blend’s percentage cannot be assigned to each substance.
Can a face serum profile describe the eye serum?
No. Intended use, formula and directions must match the exact product.
