Key ingredients

Fragrance: confirmed fragrance-free.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Sodium hyaluronate | The salt form of hyaluronic acid, commonly used for its water solubility and stability in formulas; molecular weight varies by product rather than being uniformly smaller. | Draws and holds moisture the same way hyaluronic acid does; how easily it absorbs depends on the specific molecular weight used, which formulas don't always disclose. |
| Panthenol | Pro-vitamin B5, which converts to pantothenic acid once absorbed into skin. | Hydrates as a humectant, supports wound healing, and has anti-inflammatory, soothing effects on irritated skin. |
| Hyaluronic acid | A humectant naturally found in skin, capable of holding many times its weight in water. | Draws moisture into the skin's surface, helping it look and feel plumper and more hydrated. |
| Hydrolyzed Hyaluronic Acid | Hyaluronic acid broken down into smaller fragments for easier absorption. | Delivers hydration to the skin's upper layers more readily than larger-molecule hyaluronic acid. |
