Key ingredients
These are the ingredients Dr. Althea highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.
Fragrance: No fragrance or essential oil appears in the published ingredient list; brand confirmation pending.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Centella asiatica leaf water | The water-based distillate of centella asiatica leaves, often used as the base of a formula in place of plain water. | Brings the soothing, skin-conditioning side of centella in a gentler, less concentrated form than a concentrated extract. |
| Centella asiatica extract | A plant extract, also called Cica or tiger grass, long used in traditional medicine for wound healing. | Calms redness and irritation and supports the skin barrier; some preclinical and limited clinical research suggests it may also support collagen production, though more rigorous long-term studies are still needed to confirm this. |
| Niacinamide | A form of vitamin B3, one of the most studied ingredients in cosmetic dermatology. | Strengthens the skin barrier by boosting ceramide production, helps even out tone by limiting pigment transfer to skin cells, and can reduce the look of enlarged pores. |
| 3-O-Ethyl Ascorbic Acid | A more stable, gentler derivative of vitamin C. | Converts to active vitamin C once in the skin; brightens and fights free radicals with less irritation risk than pure ascorbic acid. |
| Ascorbic Acid | Pure vitamin C, the classic reference form and among the most extensively studied, though prone to oxidizing (degrading) once opened. | A strong antioxidant that helps brighten and even skin tone; actual potency depends heavily on concentration, pH, and formulation, which isn't always disclosed, so it isn't automatically stronger than a stable derivative at an adequate dose. |
| 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. |
| 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. |
