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: No fragrance or essential oil appears in the ingredient list on file; brand confirmation pending.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Ethylhexyl triazone | A modern chemical UVB filter (Uvinul T 150). | Absorbs UVB light efficiently and is photostable. |
| Terephthalylidene dicamphor sulfonic acid | A water-soluble chemical UVA filter (Mexoryl SX). | Absorbs UVA light and is highly photostable. |
| Diethylamino hydroxybenzoyl hexyl benzoate | A modern chemical UVA filter (Uvinul A Plus). | Absorbs long-wave UVA light 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. |
| 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. |
| Adenosine | A compound naturally present in skin cells, used in skincare as an anti-aging active. | Recognized by South Korea's MFDS as a functional anti-wrinkle ingredient at 0.04% concentration, based on clinical studies showing measurable fine-line improvement; a real but modest effect, not a retinoid substitute. |
| Hydroxypinacolone retinoate | A newer retinoid ester that acts on retinoid receptors without needing to be converted first. | Used for texture and fine-line care and is often better tolerated than retinol.Note: Retinoids can irritate, and they are generally avoided in pregnancy. Introduce gradually and keep using sunscreen. |
