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 ingredient list on file; brand confirmation pending.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| 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. |
| Sodium DNA (PDRN) | Polydeoxyribonucleotide, DNA fragments commonly derived from salmon, used in Korean regenerative skincare. | Studied for supporting collagen production and tissue repair; a newer ingredient category with a shorter independent track record than long-established actives. |
| 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. |
| 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. |
