Who else has tried vitamin C serums that oxidized too fast, smelled strange, or just…did nothing? According to a recent survey of more than 600 NewBeauty readers,* Drunk Elephant C‑Firma Fresh Vitamin‑C Day Serum ($79) is a rare formula that actually delivers visible brightness and firmness while staying potent. The freshly mixed, 15‑percent L‑ascorbic acid serum is packed with antioxidants, fruit enzymes, ferulic acid and vitamin E to help visibly firm, even tone, smooth texture and defend skin against pollution and UV‑generated free radicals.
41‑year‑old reviewers love the combination of potency and convenience. One shared that they’d been searching for an “affordable, effective vitamin C serum,” and that C‑Firma “worked well,” adding that the clean ingredients and easy Sephora access were major bonuses. Another 48‑year‑old called it their “favorite serum,” noting that it brightens and helps their skin overall.
Fans also appreciate the unique two‑part system, which you mix yourself to activate the vitamin C at peak freshness. A 63‑year‑old reviewer put it best: “Love this product because you mix the Vit C at the time of use so potency is active.” Others echo the same benefits—a 43‑year‑old said their skin felt “glowing and smooth” after using it, highlighting the instant radiance boost the serum is known for.
Between the potent 15‑percent vitamin C, the antioxidant support of ferulic acid and vitamin E, and the freshly mixed delivery system, shoppers say Drunk Elephant C‑Firma Fresh is the kind of brightening serum that makes a visible difference.
