Vitamin C Antioxidant Consultation & FAQ
Q: Which Vitamin C serum is right for my skin type?
A: Selection is primarily based on skin type and concerns. C E Ferulic is the gold standard for normal to dry skin. Phloretin CF is optimized for oily or combination skin with discoloration issues. For those with highly reactive or sensitive skin, Serum 10 AOX+ provides a lower concentration of L-ascorbic acid to build tolerance while still delivering effective environmental protection.
Q: Why does the color of Vitamin C serums vary or change over time?
A: Pure Vitamin C (L-ascorbic acid) is naturally prone to oxidation. While SkinCeuticals formulations are highly stable, it is normal for the serum to darken slightly after opening. Due to the Duke Antioxidant patent, the formula remains effective even if the color shifts to a light amber. For maximum potency, we recommend using the bottle within 6 months of opening.
Q: Is Silymarin CF specifically better for acne-prone skin?
A: Yes. Silymarin CF is a breakthrough oil-free Vitamin C serum that combines 0.5% silymarin, 15% L-ascorbic acid, and 0.5% ferulic acid. It is uniquely designed to prevent oil oxidation, which can lead to breakouts. It is the ideal choice for individuals who want both anti-aging antioxidant benefits and clearer, blemish-free skin.
