Key ingredients
These are the ingredients The Saem highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.
Fragrance: Conflicting third-party sources on this product's fragrance content -- one retailer lists Fragrance in the INCI, another describes it as scent-free -- not independently confirmed either way.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Arginine | An amino acid used in skincare as a humectant and skin-conditioning ingredient. | Helps draw and retain moisture, and is part of the skin's natural moisturizing factor. |
| Squalane | A stable, skin-identical oil, usually plant-derived (from olives or sugarcane) in modern formulas. | An emollient that softens skin and helps prevent moisture loss without feeling heavy or greasy. |
| Ceramide NP | One specific, well-studied type of ceramide used in skincare formulas. | Reinforces the skin barrier and helps it retain moisture, the same core ceramide function. |
| Cholesterol | One of the three core lipids (alongside ceramides and fatty acids) that make up the skin barrier. | Works together with ceramides and fatty acids to reinforce the barrier and reduce moisture loss. |
| 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. |
| 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. |
| Glutathione | An antioxidant naturally produced by the body, also used topically in some brightening formulas. | Helps neutralize free radicals and is marketed for brightening, though topical absorption and efficacy are less established than oral or injectable use. |
| 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. |
