What we found
Based on how this product compares to others in the serums category, cross-referenced against retailer listings and market data.
Strengths
- + Freeze-dried vitamin C ball melted into the serum at first use — the ascorbic acid stays unoxidized until you mix it
- + Niacinamide in both the ball and the liquid serum
- + Third-party clinical testing behind it (n=55, 4 weeks)
- + No parfum in either INCI
Worth knowing
- - $4.63/mL — $37.00 for an 8 mL single 30-day course
- - The final mixed vitamin C % is unknown — the "20%" figure describes the ball, not the mixed serum
- - Must be used within 30 days of mixing, then discarded
- - Fresh-mixed L-ascorbic acid can sting
Key ingredients
These are the ingredients Dr. Jart+ highlights for this product, cross-checked against general dermatological and cosmetic-chemistry sources, not a full INCI list.
Fragrance: confirmed fragrance-free.
| Ingredient | What it is | What it does for skin |
|---|---|---|
| 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. |
| 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. |
| Hyaluronic Acid | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| Sodium Hyaluronate | A specific active or extract in this formula. | Not yet independently verified against general dermatology sources. |
| 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. |
