Safety Information
For external use only. This is an antioxidant serum, not a sunscreen, and it does not replace daytime sun protection. Avoid direct contact with the eyes and rinse thoroughly with water if the serum gets into them. Discontinue use if irritation occurs. Replace the cap after use, keep away from direct sunlight, and store out of reach of children.
Not recommended for:
- Anyone with a known sensitivity to an ingredient in the list — the formula contains lactoferrin, a milk-derived protein.
- The eye contour, which has its own formula in this line.
- Broken, irritated or sunburned skin — wait until the skin has settled.
- Use as a substitute for daily broad spectrum sunscreen.
Frequently Asked Questions
Morning or evening?
The brand directs one to two pumps morning and evening. If you only use it once a day, make it the morning, under sunscreen, where an antioxidant does most of its work.
How is it different from A-LUMINATE Brightening Serum?
C-RADICAL is the broad daily shield — vitamin C plus a wide antioxidant blend against pollution, light and general environmental stress. A-LUMINATE is the targeted one, aimed at the look of specific dark spots and patches. Applied together, C-RADICAL goes on first.
Will it sting like other vitamin C serums?
It uses sodium ascorbate rather than straight L-ascorbic acid, and it is scent-free and non-tacky. Most people find it noticeably gentler than a traditional acidic vitamin C.
Does it replace my sunscreen?
No. Antioxidants and sunscreen do different jobs. Use this underneath a broad spectrum SPF every morning.
Will it oxidise and turn orange in the bottle?
The vitamin C is encapsulated for stability, which is the point of this formulation. Keep the pump closed and store it away from direct sunlight.
