Ceramides
A 28-day trial in adults with moderate eczema studied a ceramide-rich cream and cleanser together. Hydration and water-loss measures improved; eczema severity did not differ between groups. The study had manufacturer involvement.
Spada et al., 2021 · randomized regimen study ↗This tests a complete two-product regimen, not isolated ceramide NP. It does not prove that any ceramide cream treats eczema.
03 / YOUR ROUTINE
Official directions and routine order
Official directions
Apply a few drops and pat in. Use morning and night before oils or moisturizers. For daytime use, Anua says to use with SPF 30 or higher.
Official directions checked 2026-10-24 ↗Use SPF 30+ for daytime per the label.
How much niacinamide does this serum contain?
Anua lists 3% niacinamide with zinc in this rice-based hydrating serum and highlights the pair for excess-oil care. The stated percentage helps distinguish it from products with an undisclosed niacinamide level. The hydration study above does not measure an oil-control effect.
Official product reference ↗What did the four-week hydration study measure?
Anua’s US product page reports a 45.4% improvement in skin moisture retention after two weeks and 63.9% after four weeks. The footnote identifies 22 subjects, a Vapometer measurement, and an external-stimulation skin-barrier test conducted from 2024-03-25 to 2024-04-24 by the Korea Institute of Dermatological Sciences. The product page does not provide the full protocol, comparator or raw data, so these remain brand-reported study results.
Apply a few drops and pat in before oils or moisturizer, morning and night. Anua recommends SPF 30 or higher during daytime use. Several ingredient names in its online list are misspelled; use the package label for their exact spelling.
| Item | Published detail | Limit |
|---|---|---|
| Moisture-retention result | 45.4% after 2 weeks; 63.9% after 4 weeks | 22 subjects; Vapometer; barrier evaluation after external stimulation; Korea Institute of Dermatological Sciences, 2024-03-25–04-24. Full protocol and comparator not shown. |
| Routine place | Before oils or moisturizers; daytime with SPF 30+ | No amount beyond “a few drops” stated |
| Ingredient panel | Rice water, niacinamide, panthenol, ceramide NP among readable entries | Some names are corrupted in page text; verify against package before presenting a full INCI |
