Why does C E Ferulic turn brown over time?

Slight color change from clear to light yellow is normal and indicates the vitamin C is active. However, if it turns dark brown or orange, the product has oxidized and should be replaced for maximum efficacy.

Can I use this with retinol products?

Yes, but use C E Ferulic in the morning and retinol at night. This prevents potential irritation and allows both ingredients to work optimally at their preferred pH levels.

How long does one bottle typically last?

With proper daily use (4-5 drops), one 30ml bottle should last approximately 3-4 months. A little goes a long way with this concentrated formula.

Is this suitable for sensitive skin?

While formulated for most skin types, those with very sensitive skin should introduce gradually. Our SkinIQ analysis can help determine if this concentration is right for you or if you should start with a gentler vitamin C option.

About SkinCeuticals C E Ferulic with 15% L-Ascorbic Acid

SkinCeuticals C E Ferulic is the gold standard of antioxidant serums, featuring a synergistic combination of 15% pure vitamin C (L-ascorbic acid), 1% vitamin E (alpha tocopherol), and 0.5% ferulic acid. This patented antioxidant combination provides up to 8 times the skin's natural protection against environmental damage from UV rays, pollution, and free radicals. The formula's unique pH and stabilization technology ensures maximum potency and absorption. Clinical studies demonstrate that C E Ferulic stimulates collagen production, reduces fine lines and wrinkles, improves skin firmness, and brightens overall complexion. The serum's lightweight, fast-absorbing formula is suitable for daily use and serves as an excellent primer under sunscreen. With consistent use, users report visibly brighter, more even-toned skin with improved texture and reduced signs of photoaging. This professional-grade serum comes in a 30ml amber bottle with dropper applicator to protect the vitamin C from light degradation. C E Ferulic is particularly beneficial for patients with sun damage, dullness, or those seeking comprehensive anti-aging prevention.

How to Use

Apply 4-5 drops to clean, dry skin in the morning after cleansing and toning. Gently pat into face, neck, and chest, avoiding the eye area. Allow to absorb for 10-15 minutes before applying moisturizer and sunscreen. Use daily for best results. Start with every other day if new to vitamin C to build tolerance.

Pro Tip from Our Clinicians

Store C E Ferulic in a cool, dark place to maintain potency. The serum pairs beautifully with our IPL treatments - use it 2 weeks post-treatment to enhance brightening results and protect newly renewed skin. For sensitive skin, our SkinIQ analysis can determine if you should start with a lower concentration vitamin C first.
