No word of a lie but the best vitamin C serum in the world is SkinCeuticals C E Ferulic. The rejuvenating serum constantly hits top spot on any ‘best of’ lists regarding the vitamin best known for glow.
It has a unique formula that has never been equalled, and it’s a proper Hall of Fame beauty buy. An iconic serum, it is used by all ages and skin types and it doesn’t have fans, it has devotees like Hailey Bieber and Gwyneth Paltrow.
As it celebrates its 20th birthday in 2025, we’ve taken a look at its formulation, how to use it, and how it works on the skin for 72 hours after application.
SkinCeuticals C E Ferulic

C E Ferulic was launched in 2005 with a unique formulation that includes Vitamin C (15% l-ascorbic acid) is one part of the serum, along with 1% alpha-tocopherol (vitamin E) to help with hydration and radiance, and 0.5% ferulic acid, which reduces inflammation, evens skin tone and stabilises the vitamin C.
Vitamin C is notoriously unstable in skincare and affected or disabled by heat, light and air and if it has a pH level over 3.5 it won’t penetrate the skin. What SkinCeuticals got bang-on with C E Ferulic was a stable and effective blend that has the right pH, and the combination of the three key components keeps that vitamin C protected so it can work correctly.
What It Does
C E Ferulic has been tested in clinical studies over 50 times and it makes every best-seller list for the best vitamin C serum in countries across the globe. It is pricey at €191.45, but fans say it’s the best alternative to clinic treatments and that it’s the best vitamin C serum because it actually works.
Eight times more powerful than using vitamin C by itself, the antioxidant power of C E Ferulic works on existing age signs, protects the skin from further damage, reduce wrinkles and poor skin texture, and it gives skin a glow like no other serum.
How To Use
The serum works on all skin types and mature skin to reverse environmental and UV damage on the skin. A morning product, it’s best applied to cleansed skin and allowed to dry before following on with moisturiser and/or sunscreen (if you have two separate products).
Only four or five drops are needed for the face, neck and decolletage, and it’s worth treating all three areas as they pick up the most amount of damage along with the hands. Dermatologists love it too and they say it’s the best vitamin C serum so they recommend it for everyday anti-ageing and for speeding up the healing process after laser treatments.
Results
Daily use delivers results, and over time you should visibly see reduced lines, wrinkles and pore size. Longterm use will deliver firmness and that glow you get from using vitamin C on the skin.
Fans say their skin is transformed in just a few months, and it’s brilliant for slowing those crepey lines that creep in on the chest area between the breasts. If these results are what you are hoping for, then this is the best vitamin C serum for total rejuvenation without professional treatment. Happy Birthday C E Ferulic, 20 years as the world’s best serum and still going strong.
