| Ingredient | What it does |
|---|---|
| Eau) Solvent/vehicle | Eau (water) is the most common base ingredient in skincare formulations, serving as a solvent and carrier for other ingredients. It has no therapeutic activity on its own but is essential for dissolving and dispersing actives, humectants, and other components. |
| 3-O-Ethyl Ascorbic Acid Key active Antioxidant / brightening vitamin C derivative | 3-O-Ethyl Ascorbic Acid is a stable, water-soluble ethylated derivative of vitamin C that converts to ascorbic acid in the skin, providing antioxidant protection and supporting collagen synthesis and pigmentation control. It is valued for greater stability than pure L-ascorbic acid while delivering similar brightening and anti-aging benefits. |
| Squalane Emollient / occlusive moisturizer | Squalane is a saturated, stable hydrocarbon derived from squalene (sourced from plants like olives or sugarcane, or shark liver) used as a lightweight emollient that softens skin and reinforces the skin barrier by reducing transepidermal water loss. It is well tolerated, non-comedogenic for most users, and serves as a base or carrier ingredient rather than a therapeutic active. |
| Sodium Citrate pH adjuster / chelating agent | Sodium citrate is the sodium salt of citric acid used in skincare primarily as a buffering agent to stabilize formulation pH and as a chelator that binds metal ions to improve product stability. It is a base/formulation ingredient rather than a therapeutic active. |
| Tocopheryl Acetate Key active Antioxidant | Tocopheryl acetate is a stable, esterified form of vitamin E used in skincare as an antioxidant and conditioning agent. It is converted to active tocopherol in the skin, helping protect against oxidative stress and supporting the skin barrier. |
| Colloidal Oatmeal Key active Skin protectant / soothing agent | Colloidal oatmeal is finely milled whole oat (Avena sativa) suspended for topical use, recognized as an FDA skin protectant. It contains beta-glucans, avenanthramides, and lipids that help moisturize, support the skin barrier, and reduce itch and inflammation. |
| Chrysanthemum Parthenium (Feverfew) Extract Key active Antioxidant / anti-inflammatory soothing agent | Feverfew extract is a botanical derived from Tanacetum parthenium used in skincare for its antioxidant and anti-inflammatory properties, often to calm redness and irritation. Cosmetic formulations typically use parthenolide-depleted feverfew to reduce sensitization risk while retaining soothing benefits. |
