SkinCeuticals C E Ferulic (New Enhanced Formula) is the #1 dermatologist recommended vitamin C serum among medical aesthetic skincare brands. It keeps the same synergistic antioxidant base — 15% pure L-ascorbic acid (vitamin C), 1% alpha-tocopherol (vitamin E), and 0.5% ferulic acid — now with two new ingredients: 0.3% carnosine and 1% endophytol. The upgrade maintains 98.7% continuity with the original formula, so everything you love stays the same — the texture, the feel, and the iconic bottle are unchanged. New Enhanced Formula: What Changed The enhanced, patent-pending formula adds two ingredients to further support visible skin longevity. Carnosine (0.3%) is a dipeptide of two amino acids that acts as a strong antioxidant. Endophytol (1%) is a dandelion root extract with strong anti-pollution and anti-inflammatory benefits. Together, this double patent-pending modernization extends antioxidant efficacy: the serum is now proven to visibly reverse 10 years of aging signs of lack of firmness and dullness, and is clinically demonstrated to reduce combined oxidative damage generated by UVA/UVB rays, ozone, and diesel exhaust by up to 41% — making skin up to 8X stronger against environmental aggressors. It has been physician-tested with 7 different lasers to maximize results. Key Ingredients and How They Work L-ascorbic acid (15%) is the only form of vitamin C with peer-reviewed evidence supporting its ability to penetrate the skin barrier at this concentration. Once absorbed, it neutralizes free radicals generated by UV exposure, pollution, and infrared radiation — the primary drivers of premature skin aging. Alpha-tocopherol (vitamin E, 1%) works synergistically with vitamin C to strengthen the skin's lipid barrier. Ferulic acid (0.5%) stabilizes both vitamins C and E, extending their protective activity and boosting photoprotection. New to the enhanced formula, carnosine adds another layer of antioxidant defense, while endophytol — the dandelion root extract — targets pollution damage and helps fight the inflammation that drives visible aging. The formulation is pH-adjusted to 2.0–3.5, the range at which L-ascorbic acid is most bioavailable. Paraben-free, alcohol-free, fragrance-free, dye-free, and silicone-free. How to Use Apply 4-5 drops to clean, dry skin every morning. Smooth over face, neck, and chest. Allow 1-2 minutes to absorb before applying moisturizer and sunscreen. This is a treatment product — use it after cleansing and toning, before heavier creams. The serum has a slight oily texture that absorbs fully within minutes. The amber tint is normal and does not indicate oxidation; discard only if the serum turns dark brown or orange. What to Expect Within the first 2-4 weeks, most users notice improved skin brightness and a more even complexion. Reduction in the appearance of fine lines and firmer-feeling skin typically becomes noticeable at the 12-16 week mark with daily use. The enhanced formula clinically corrects 8 signs of aging, including the appearance of fine lines and wrinkles, discoloration, loss of firmness, and brightness. Once absorbed, it remains effective for a minimum of 72 hours, meaning occasional missed days do not reset your results. Who Should Use This Ideal for normal, dry, and sensitive skin types seeking comprehensive antioxidant protection and visible anti-aging benefits. Particularly effective for patients concerned with photoaging, hyperpigmentation, and loss of firmness. Not recommended for oily or acne-prone skin — consider SkinCeuticals Phloretin CF or Silymarin CF instead. Safe for post-laser use with physician consultation. Frequently recommended by ELLEMES providers as the cornerstone of a clinical anti-aging routine. Pairs with in-office treatments like chemical peels and laser resurfacing to protect and extend treatment results.
