Veranum Active C 25% Vitamin C Ampoule — Korean Brightening Serum for Dark Spots, Firming & Even Tone (Non-Irritating, Stabilized Vitamin C)
Size: 1.2 fl.oz.
The highest-strength Vitamin C in K-beauty — without the sting. Most serums cap out at 15–20% because higher usually means irritation. Veranum Active C delivers a full 25% stabilized Vitamin C in a buffered, barrier-supporting formula, so you get maximum brightening power even if past Vitamin C left your skin red or tingling.
More than a Vitamin C serum, Active C is a next-generation skin-strengthening ampoule — powered by 25% stabilized Vitamin C, Triple Collagen, and CICA-Exo™ — that visibly brightens dull skin, firms uneven texture, and helps fade the look of dark spots while supporting a calm, resilient skin barrier.
Why you'll love it
- Highest-strength 25% — without irritation: full-power brightening in a buffered, stabilized formula designed for sensitive and reactive skin.
- Visibly fades dark spots & evens tone: Vitamin C is one of the most studied ingredients for helping brighten hyperpigmentation, sun spots, and post-blemish marks.
- Firms & strengthens with Triple Collagen + CICA-Exo™: supports bounce and barrier resilience, not just surface glow.
- Stays potent: stabilized Vitamin C resists the oxidation that turns ordinary serums yellow and useless — every drop stays active.
- Lightweight Korean ampoule: absorbs fast, layers cleanly under moisturizer, sunscreen, and makeup — no sticky finish, no pilling.
Made for skin that reacts
If strong Vitamin C has always been too harsh for you, this is the one that changes your mind. The stabilized 25% system is built to deliver results without the burn — a true daily-use brightening ampoule for glass-skin radiance.
How to use
Every morning, apply 3–4 drops to clean skin before moisturizer. Always follow with SPF — Vitamin C works best paired with daily sun protection.
