Fit by skin type

Take the skin testA juicy Korean serum that intensely hydrates for a smooth, supple complexion and is hypoallergenic, dermatologist-tested, and suitable for sensitive skin
Water Bank Blue Hyaluronic Serum is a lightweight serum from LANEIGE, a brand based in Korea. The formula is built mainly around hydration. The ingredient list runs to 27 ingredients, each broken down in full below.
By its ingredient list the formula reads as light: water and humectants lead, with emollients kept lower in the order. Hydration is handled by Butylene Glycol, Glycerin and Propanediol, humectants that pull water into the upper layers of skin rather than sealing it there.
Hydration: High. Ingredients that pull and hold water in the upper layers of skin, and here that comes from Butylene Glycol, Glycerin, Propanediol and Ethylhexylglycerin.
Barrier support: Moderate. Lipids and repair signals that support skin barrier integrity, and here that comes from Squalane and Hydrogenated Lecithin.
On richness alone it suits Balanced, Combination (oily) and Oily skin best, and is the least natural fit for Dry and Combination (dry) skin. Nothing in the list is flagged as a common irritant, which is a reasonable starting point for reactive skin — though a patch test is still the only way to know.
The formula contributes little or nothing on antioxidant protection, oil control, brightening and tone and cell renewal. That is not a fault — most products are not meant to do everything — but if one of those is your priority, this is not the product that will address it. 3 ingredients on the label have not been matched to our database yet, so the analysis above reads a slightly incomplete list.
It can be used morning and evening. In a routine it goes after toner, before moisturiser. Apply to clean, dry skin and give it a minute to absorb before the next layer. Introduce one new treatment at a time so you can identify what is working.
This summary is generated from the product's ingredient list. It is not a review, it is not the brand's own marketing claims, and it does not replace advice from a dermatologist.
Drawn purely from the ingredient list
Scored on how rich or light the formula reads from its INCI order.
No ingredient in this formula carries a common-irritant flag, making it a reasonable option for reactive skin. A patch test is still recommended, as individual skin reactivity varies.
Based on the curated benefits documented for this product's ingredients.
Attracts and locks in moisture to keep skin plump and dewy
Calms redness, irritation, and inflammation for sensitive skin
Boosts collagen and cell turnover to reduce fine lines and wrinkles
Brightens and balances complexion for a more uniform appearance
Regulates sebum production to reduce shine and greasiness
None of the ingredients in this formula are associated with these benefits. This is not unusual, as most products are designed to target a limited number of concerns.

Solvents, emollients, texture agents and preservatives — the formula that carries the actives.
Judged by the same curated rules our routine checker uses. It reads the ingredients, not the label.
Nothing in this formula belongs to a group our rules can put in conflict, so it layers freely. Order still matters — thinnest texture first.
This product is the "Treat" step.
Flags to check, not verdicts. None of this is medical advice — if you are pregnant, breastfeeding or treating a skin condition, ask a doctor.
Most ingredients do more than one job, so these counts add up to more than the 27 ingredients on the label.

Dissolves and carries everything else
Lifts oil and dirt, or holds oil and water together
Softens and smooths by filling gaps between skin cells
