How is this product different from the previous formula? 

The new CE Ferulic is still powered by our classic triple-antioxidant blend (15% Pure Vitamin C, 1% Vitamin E, 0.5% Ferulic Acid) for advanced environmental protection . The addition of 2 new ingredients, 0.3% Carnosine, and 1% Endophytol work synergistically with this combination and boost anti-inflammatory and antioxidant benefits to promote visible skin longevity.

Is the new C E Ferulic formula as efficacious as the original? 

Yes, this formula provides all benefits of our original C E Ferulic formula, including improving 8 signs of aging beyond wrinkles and 8x stronger skin against environmental aggressors. Now, though, it is proven to visibly reverse 10 years of aging signs, of lack of firmness and dullness.

What are the new ingredients in the new C E Ferulic formula? 

While keeping our classic triple-antioxidant combination, we have boosted the formula with two new ingredients to improve visible skin longevity:

0.3% Carnosine: A powerful dipeptide of 2 amino acids that acts as a strong antioxidant.
1% Endophytol: A dandelion root extract with strong anti-pollution and anti-inflammatory benefits.

Does the new formula smell the same as the original C E Ferulic? 

Yes. Since we do not add artificial fragrances or preservatives to our products, what you smell is the natural scent of the vitamins and botanical extracts. In consumer testing, users found no significant difference in the sensory experience or application between the original and the new formula. (Note: Just like the original, it is normal for the serum to darken over time. Our stability data confirms that C E Ferulic remains effective and safe to use, no matter the color.)

Is it still safe for me to use the original C E Ferulic? 

Yes, absolutely. The original C E Ferulic formula remains safe, stable, and highly effective. You can continue to use your current bottle daily (4-5 drops in the morning) and we recommend using it within 3-6 months of opening. Once finished, you can seamlessly transition to the new enhanced formula.

Why did you change the original C E Ferulic formula? 

At SkinCeuticals, we are committed to driving skincare forward through scientific innovation. After 20 years as the gold standard in antioxidant care, we meticulously enhanced C E Ferulic to incorporate the latest breakthroughs in longevity science. This double patent-pending modernization allows us to extend antioxidant efficacy and improve visible skin longevity as well as protect against modern daily stressors like heat and visible light, without changing the beloved texture, scent, and safety profile of your favorite serum.

Is C E Ferulic recommended to use after professional procedures?

C E Ferulic® has been clinically tested and is safe to use after professional laser treatments. Always consult with a physician or provider for individualized post-procedure care.

What color should C E Ferulic be when first opened?

Upon breaking the plastic and opening, the color of C E Ferulic® can vary, ranging from relatively clear to pale yellow to amber. Due to the key ingredients in the formula, the vitamin C serum will begin to darken in color over time. Please note that this does not mean the formula has become ineffective.

How long does a bottle last after opened?

It is normal for SkinCeuticals ferulic acid serum for the face to darken after opening due to air and light exposure. The formula will remain effective. It is recommended to be used within 3-6 months after opening with daily application of 4-5 drops to the face, neck, and chest.

When will I start seeing results after using C E Ferulic?

Our SkinCeuticals C E Ferulic® study looked exclusively at 12-week data where we saw significant results.

Can C E Ferulic be used with a retinoid or retinol?

C E Ferulic® should be the first step as part of your morning regimen, while a retinol or retinoid should be used as one of the final steps of your nighttime regimen. There is no conflict or issue to use both within the same daily skincare regimen. Please consult your skincare physician with any questions.

Is it safe to use C E Ferulic on sensitive skin?

C E Ferulic® is recommended for people with wrinkles and/or fine lines. Every skin type is different, so while some people with sensitive skin will have no issue using C E Ferulic®, some might. We offer a variety of antioxidant options so that there is a suitable option for every skin type.
