Q: What makes SkinCeuticals CE Ferulic different from other vitamin C serums?
A: CE Ferulic features a patented antioxidant combination of 15% pure L-ascorbic acid, 1% vitamin E, and 0.5% ferulic acid. This synergistic formula provides 8x environmental protection and remains effective for 72 hours after application, unlike unstable vitamin C serums that degrade quickly.
Q: How should I apply CE Ferulic for maximum effectiveness?
A: Apply 4-5 drops to clean, dry skin in the morning before moisturizer and sunscreen. The serum should be used on face, neck, and chest. Wait 10-15 minutes before applying other products to allow proper absorption and activation of the antioxidant complex.
Q: Can I use CE Ferulic with retinol or other active ingredients?
A: Yes, but use CE Ferulic in the morning and retinol at night. The vitamin C provides daytime protection while retinol works for nighttime renewal. Always use broad-spectrum SPF 30+ during the day when using vitamin C products.
Q: Why does CE Ferulic have a brown/amber color?
A: The amber color indicates the serum contains pure L-ascorbic acid in its most potent form. This is normal and shows the product is authentic. Store in a cool, dry place and use within 6 months of opening for optimal potency.
Q: What results can I expect and how quickly?
A: Most users notice improved skin radiance within 1-2 weeks. Clinical studies show significant improvement in fine lines, firmness, and brightness within 6-8 weeks of consistent daily use. The 8x environmental protection begins immediately upon application.
Q: Is CE Ferulic suitable for sensitive skin?
A: CE Ferulic is formulated for normal to dry skin types. If you have sensitive skin, start with every other day application and gradually build tolerance. For sensitive or oily skin, consider SkinCeuticals Phloretin CF instead.
Q: How long does one 30ml bottle last?
A: With daily use of 4-5 drops, one 30ml bottle typically lasts 3-4 months, making it excellent value for a professional-grade vitamin C serum with clinically proven results.
Q: Can I use this after professional treatments?
A: CE Ferulic is excellent for post-treatment care as it supports healing and provides antioxidant protection. However, wait 24-48 hours after aggressive treatments like chemical peels or laser procedures, or follow your practitioner's specific guidelines.
Q: Do you ship internationally?
A: Yes, we ship worldwide from Ireland. We regularly serve customers in the UK, United States, Germany, Italy, Spain, Cyprus, Australia, France, Netherlands, Canada, and many other countries throughout Europe, Asia, and the Middle East.
Q: What's the difference between CE Ferulic and other SkinCeuticals vitamin C serums?
A: CE Ferulic is designed for normal to dry skin with 15% L-ascorbic acid, while Phloretin CF targets oily skin with 10% vitamin C plus phloretin. CE Ferulic provides superior anti-aging benefits, while Phloretin CF focuses more on discoloration and pore refinement.
