Hyaluronic acid is a humectant — it holds water. This cream uses a low-molecular-weight, or smaller, form. Smaller hyaluronic acid does penetrate a bit further than large forms.
But "2,000 times smaller" is a size comparison, not a measure of results. Smaller does not mean 2,000 times better, and there is no independent proof it hydrates more. The number is memorable, not meaningful.
The good news is that the rest of the formula does real work. Squalane, ceramide NP, cholesterol, and beta-glucan are solid barrier and humectant ingredients. You are getting a good cream — just not for the reason on the box.
| Key active | Hyaluronic acid + squalane + ceramide NP |
| Texture | Rich, cushiony cream |
| Best for | Dry, dehydrated skin |
| Approximate price | $38 for 50 ml |
The formula is genuinely good, and better than the marketing suggests. Squalane, ceramide NP, and cholesterol are in here — real barrier lipids, not a token dusting. Beta-glucan is a strong humectant.
The texture is a pleasure to use: cushiony, rich, not greasy.
A refill pod is available, which is cheaper and less wasteful than buying a new jar.
If you have dry skin, this will work. It just will not work for the reason the box gives.
"Blue Hyaluronic Acid — 2,000x smaller than regular HA" is a size ratio, not a result. It means Laneige uses a low-molecular-weight hyaluronic acid. That is a real thing, and smaller HA does penetrate somewhat further — but "2,000 times smaller" is not "2,000 times better," and there is no independent evidence it hydrates more effectively. The number is chosen because it is impressive, not because it means anything.
The "100 hours of hydration" claim is brand-run and difficult to square with the fact that you wash your face.
It contains fragrance — and the product is marketed as "sensitive-skin friendly." Multiple reviewers find it strongly perfumed. Those two things do not sit well together, and fragrance is a leading cause of cosmetic contact allergy.
$38 for 50 ml buys you ceramides and squalane you can get for a third of the price at a pharmacy.

1. Human skin penetration of hyaluronic acid of different molecular weights as probed by Raman spectroscopy (https://doi.org/10.1111/srt.12228) — Directly supports the claim that low-molecular-weight HA penetrates somewhat: low MW HA (20-300 kDa) passes through the stratum corneum while high MW HA (1000-1400 kDa) does not. 2. Hyaluronic acid and HA-modified cationic liposomes for promoting skin penetration and retention (https://doi.org/10.1016/j.jconrel.2023.03.049) — Supports that low-molecular-weight HA (5-8 kDa) can pass through the stratum corneum into epidermis and dermis whereas high-molecular-weight HA is trapped on the surface, backing the page's point about smaller HA penetrating. 3. Optimization of physiological lipid mixtures for barrier repair (https://doi.org/10.1111/1523-1747.ep12340135) — Supports that ceramides, cholesterol, and free fatty acids are the physiological stratum-corneum lipids required for skin barrier repair, backing the page's claim that squalane/ceramide/cholesterol are real barrier lipids. 4. Biological importance and applications of squalene and squalane (https://doi.org/10.1016/B978-0-12-416003-3.00014-7) — Supports that squalane has documented skin-hydrating and emollient activity, backing its inclusion as a genuine skin-conditioning/barrier lipid. 5. Skin health promotion effects of natural beta-glucan derived from cereals and microorganisms: a review (https://doi.org/10.1002/ptr.4963) — Supports the claim that beta-glucan is a strong humectant by reviewing its moisturizing effect and skin permeation on skin.
