Description
This is a vitamin C serum from Drunk Elephant that comes as a two-part system: a liquid base and a powder vial of 15% l-ascorbic acid. You mix them together before first use to maximize potency and freshness. The brand says the formula illuminates and firms skin while helping to even out complexion, and it contains an antioxidant complex with 0.5% ferulic acid and 1% vitamin E alongside pumpkin ferment extract and sodium hyaluronate. L-ascorbic acid is a form of vitamin C that works as an antioxidant; ferulic acid and vitamin E are antioxidants that enhance its effects; sodium hyaluronate is a humectant that draws water into skin.
Per the brand, this serum addresses fine lines, dullness, uneven texture, loss of firmness, dark spots, redness, and acne. The brand says it's suitable for all skin types and formulated at a skin-friendly pH of 2.5 and dermatologist tested. It's formulated without essential oils, silicones, chemical sunscreens, sulfates, synthetic fragrances and dyes, or drying alcohols. Per the brand, it is vegan and cruelty-free certified. Use it once daily in the morning on clean, dry skin. The trade-off is the mixing step required before first use and the need to pair it with sunscreen during the day.

FAQs
Why do I need to mix this serum before use?
Drunk Elephant designed the two-part system so you mix it fresh before first use to maximize its potency and enhance its freshness for longer.
Can I use this serum at night?
No, this is a daytime serum only. Use it in the morning, and the brand reminds you to always apply sunscreen afterward.
What happens when I mix the powder and liquid?
Bubbles will form when you shake the powder and liquid together for one minute—that's normal and expected. Keep shaking until the powder fully dissolves.
Is this suitable for sensitive skin?
Per the brand, it's suitable for all skin types and dermatologist tested. However, given the active vitamin C content, patch test first if your skin is very reactive.
