| 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. |
| Retinol | A form of vitamin A used in skincare that skin converts into the active retinoic acid. | Supports skin renewal and visibly smooths fine lines and uneven tone with consistent use; it is among the most studied topical anti-aging ingredients.Note: Can cause dryness, peeling or sensitivity, especially when starting. Best used at night with daily sunscreen, and generally avoided during pregnancy and breastfeeding. |
| 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. |
| Hydrolyzed collagen | Collagen broken down into smaller peptide fragments for better skin penetration. | Acts as a hydrating, skin-conditioning ingredient; topical collagen is too large to replace the skin's own collagen, but supports surface hydration. |
| Tripeptide-1 | A short peptide of three amino acids (GHK) that also occurs naturally in the body. | Used as a skin-conditioning peptide that supports the look of firmer, smoother skin; evidence is mostly from small studies. |
| 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. |
