How does this differ from CE Ferulic?

Serum 15 AOX+ contains 15% vitamin C versus 20% in CE Ferulic, making it ideal for sensitive skin or those building tolerance to vitamin C. Both contain the same synergistic antioxidant combination but at different strengths.

Can I use this if I'm new to vitamin C?

Yes, 15% L-ascorbic acid is an excellent middle-ground concentration. Start every other day for the first week to build tolerance, then increase to daily morning use as your skin adjusts.

Will this cause irritation on sensitive skin?

While L-ascorbic acid can cause initial tingling, the 15% concentration is generally well-tolerated by sensitive skin types. The ferulic acid actually helps stabilize the vitamin C and reduce potential irritation.

How long will one bottle last?

With proper daily use (4-5 drops per application), one 30ml bottle typically lasts 3-4 months. Using too much product won't increase benefits and may cause irritation.

Always follow with broad-spectrum SPF 30 or higher.
