Drunk Elephant C-Firma Fresh Day Serum

Drunk Elephant C-Firma Fresh Day Serum delivers powerful brightening and anti-aging results with its 15% L-ascorbic acid concentration, but it comes with some considerations. The serum combines vitamin C with ferulic acid and vitamin E—a scientifically-proven trio that provides enhanced antioxidant protection and stability. Fresh vitamin C is crucial for efficacy, and the serum does work to visibly brighten dark spots, even skin tone, and improve overall radiance over time. The addition of pumpkin ferment and pomegranate enzymes gently exfoliates to reveal fresher skin. However, the formula has a distinct hot dog water smell that many find off-putting—this is unfortunately the natural scent of pure vitamin C. The serum also oxidizes relatively quickly despite the airless pump, turning orange-brown and losing efficacy. At this luxury price point, the quick oxidation is disappointing. The formula can also be irritating for sensitive skin, especially when first introduced. For those who can tolerate it and work through a bottle quickly, the brightening and firming results are impressive.
