Key ingredients
These are the ingredients Round Lab highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.
Fragrance: The ingredient list includes essential oils, so it is not fragrance-free.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Titanium dioxide | A mineral (physical) UV filter, used alongside or instead of zinc oxide. | Provides broad-spectrum UV protection, primarily strong against UVB with some UVA coverage. |
| Diethylamino hydroxybenzoyl hexyl benzoate | A modern chemical UVA filter (Uvinul A Plus). | Absorbs long-wave UVA light and is photostable. |
| Ethylhexyl triazone | A modern chemical UVB filter (Uvinul T 150). | Absorbs UVB light efficiently and is photostable. |
| 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. |
| Birch sap | Sap tapped from birch trees, used in Korean skincare as a lightweight hydrating base. | Commonly included for its hydrating, soothing properties, though it has less independent clinical research than more established actives. |
| 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. |
| Glyceryl glucoside | A moisturizing ingredient made by combining glycerin with glucose. | Acts as a humectant, helping skin attract and hold water. |
