Hyaluronic Acid Ceramide HA B5 Ampoule Serum

Evidence grade BSources checked 24 July 2026Research only · Not physically tested

A fragrance-free, centella-led 40 ml hydrating serum with panthenol and small disclosed amounts of sodium hyaluronate and Ceramide NP; better read as a broad humectant formula than a ceramide-heavy treatment.

Practical skin outcome

What this formula may do for skin

Best suited to
Dehydrated-feeling skin prioritizing centella, panthenol and humectants over a high ceramide content.
May help with
Increase temporary hydration and reduce a tight-feeling finish through glycerin, panthenol and humectants.
Routine role
A light hydration serum before moisturizer.
Think twice if
You are specifically shopping for a substantial ceramide treatment; the disclosed Ceramide NP amount is only 5,000 ppb.
Evidence level
formula-plausible

This is a cautious formula-based interpretation, not proof of the finished product's performance or a medical claim.

How we read the formula

The current YesStyle record lists centella asiatica extract at 36.9%, panthenol at 5,000 ppm, sodium hyaluronate at 8,000 ppb and Ceramide NP at 5,000 ppb.

Those units matter. The disclosed Ceramide NP amount is five parts per billion, so the product name should not be interpreted as evidence of a high ceramide load. Panthenol, glycerin, glycols and centella are more prominent in the published formula.

Hydrogenated lecithin, squalane and a phytosteryl amino-acid derivative add emollient and lipid context. The list contains tea-tree leaf extract but no added parfum in the cited retailer record.

What stands out

  • The source discloses percentages or ppm/ppb amounts for several headline ingredients.
  • Panthenol, glycerin, sodium hyaluronate and beta-glucan support a hydration-focused reading.
  • No added fragrance is listed in the current record.
  • The 40 ml size is larger than a conventional 30 ml ampoule.

What the sources cannot tell us

  • Ceramide NP is disclosed at only 5,000 ppb; prominence in the product name does not indicate a high concentration.
  • The detailed ingredient record comes from a retailer rather than a manufacturer page.
  • The long botanical list complicates attribution of any real-world effect.
  • We have not physically tested texture, pilling, tolerance, or packaging.
