Key ingredients
These are the ingredients medicube highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.
Fragrance: Not fragrance-free: the published ingredient list includes lemongrass leaf oil and star anise oil.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Niacinamide (5%) | Vitamin B3 at a concentration within the most clinically studied range. | Supports the skin barrier and has published evidence for visibly reducing hyperpigmentation at this dose. |
| 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. |
| 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. |
| 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. |
| Ceramide NP | One specific, well-studied type of ceramide used in skincare formulas. | Reinforces the skin barrier and helps it retain moisture, the same core ceramide function. |
| 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. |
| 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. |
| Betaine | An amino-acid-derived humectant, naturally found in sugar beets and also present in snail mucin. | Helps draw and hold moisture in the skin, and has mild soothing properties. |
