| Ingredient | What it is | What it does for skin |
|---|---|---|
| Madecassoside | One of centella asiatica's key active compounds, often isolated and purified. | A soothing, antioxidant compound studied for calming sensitive and reactive skin and supporting barrier repair. |
| Beta-glucan | A polysaccharide often derived from oats or yeast. | A soothing, hydrating ingredient studied for calming sensitive skin and supporting the barrier. |
| 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 into smaller fragments. | A humectant that holds water at the skin surface; the smaller size is meant to hydrate at a shallower depth. |
| 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. |
| Allantoin | A soothing compound, naturally occurring in some plants and also made synthetically. | Calms irritation and supports skin healing, often paired with other barrier-focused ingredients. |
