What we found
Based on how this product compares to others in the serums category, cross-referenced against retailer listings and market data.
Strengths
- + L-ascorbic acid 14.5% — printed in the INCI (145,000 ppm, 2nd ingredient)
- + Three sealed 10 g bottles opened in sequence, so less of the vitamin C oxidizes before use
- + Named-lab (P&K Skin Research Centre) testing programme behind it
- + $0.63/mL — the best concentration-adjusted value in its set
Worth knowing
- - Fragranced in both INCI versions — bergamot/litsea oils with limonene, linalool and citral
- - Two materially different INCI versions circulate for this name — check the box
- - 14.5% L-ascorbic acid is a high irritant load; evening use with daytime SPF
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: this formula contains added fragrance.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| Ascorbic Acid 14.5% | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| Bisabolol | A calming compound most commonly sourced from chamomile, though it can also be produced synthetically; an ingredient list alone doesn't confirm which source a specific product uses. | A well-documented soothing ingredient that helps calm irritation and redness, gentle enough for sensitive skin. |
| Tocopherol | The chemical name for vitamin E as typically used in skincare formulas. | Helps neutralize free radicals from UV and pollution exposure and supports the skin's moisture barrier. |
| Glutathione | An antioxidant naturally produced by the body, also used topically in some brightening formulas. | Helps neutralize free radicals and is marketed for brightening, though topical absorption and efficacy are less established than oral or injectable use. |
| 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. |
| Beta-Glucan | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| 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. |
| Sodium Hyaluronate | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
