Radiant C-F Glow Drops is a vitamin C and ferulic acid serum for a brighter, more even-looking complexion. It layers three forms of vitamin C: L-ascorbic acid, the most studied, plus two more stable derivatives.
Ferulic acid helps keep the formula stable and adds antioxidant support under your daily SPF. Rice, calendula and chamomile extracts keep the lightweight serum comfortable on skin.
- Brighter-looking skin In a split-face trial, a vitamin C serum measurably raised skin radiance within 4 weeks.
- Less sallow-looking tone In one 12-week trial, a 10% vitamin C serum lowered skin yellowness by 6.13%.
- A more even-looking tone With daily use and SPF, vitamin C helps dark spots and uneven patches look more even.
- Antioxidant support Ferulic acid helps stabilize vitamin C, and both work as antioxidants against everyday environmental stress.
- Light, fast-absorbing feel A water-light serum that sinks in quickly and layers easily under moisturizer and SPF.
Once a day, ideally in the morning; you can also use it at night. If your skin is sensitive, start every other day.
- Cleanse Wash and pat skin completely dry.
- Apply Press a few drops over face and neck with your fingertips.
