What C E Ferulic is
C E Ferulic is a daytime antioxidant serum from SkinCeuticals, sold in a 30 ml / 1 fl oz amber dropper bottle. It is applied once each morning to clean skin, underneath the rest of a routine.
The formula combines three known antioxidants: 15% L-ascorbic acid, 1% alpha tocopherol and 0.5% ferulic acid. According to the product carton, that combination enhances protection against environmental aggressors that cause dry skin, and helps diminish the look of premature ageing, lines and wrinkles.
The short version. C E Ferulic is the morning antioxidant step. It sits under everything else, it is used once daily, and its job is to help defend skin against daytime environmental stress while visibly softening the look of lines and uneven tone over time.
What's new in the 2026 formula
Two things are worth knowing about this release.
First, the active concentrations are unchanged. It is still 15% L-ascorbic acid, 1% alpha tocopherol and 0.5% ferulic acid — the ratio C E Ferulic has been built on since it launched. If that combination has been working on your skin, it has not been swapped out.
Second, the formula is now patent pending. The new carton carries a "Patent Pending Formula" mark on the front and notes "patent pending in the US" on the back panel. SkinCeuticals is also using a gold "New Patent Pending Formula" seal to flag the 2026 version.
Practically, if you already use C E Ferulic, nothing about how you use it changes. Same four to five drops, same morning placement, same 30 ml bottle.
The three actives
| Ingredient | Concentration | What it does |
|---|---|---|
| Pure vitamin CL-ascorbic acid | 15% | The potent form of vitamin C. Helps protect the skin while providing visible anti-ageing benefits. |
| Vitamin EAlpha tocopherol | 1% | The pure form of vitamin E. Helps protect the skin and replenishes healthy skin properties. |
| Ferulic acid | 0.5% | A plant-based antioxidant that helps neutralise damage and complements the benefits of vitamins C and E. |
The reason this trio is treated as a benchmark is that the three ingredients are more useful together than separately: vitamin E supports vitamin C, and ferulic acid supports both.
What the clinical data shows
SkinCeuticals reports the following results for C E Ferulic from its clinical testing.
Protocol: 52-week clinical study on 50 female subjects aged 40–60. Results measured at week 20 (USA, 2011). Figures describe visible, cosmetic change. Individual results vary.
Before and after, 12 weeks
A separate 12-week study on 75 subjects aged 25–75 produced the photography below, showing average results for wrinkles and for skin tone.
Which vitamin C serum suits your skin
SkinCeuticals makes three daytime vitamin C serums and they are not interchangeable. The right one depends on your skin type and what you want to work on.
| Serum | Main concern | Skin types | Choose it for |
|---|---|---|---|
| C E Ferulic | Visibly reduces wrinkles and firms | Normal, dry, combination, sensitive | Anti-ageing |
| Phloretin CF | Visibly improves skin tone | Normal, oily, combination | Uneven skin tone |
| Silymarin CF | Helps visibly reduce blemishes and oil | Oily, blemish-prone | Blemish-prone skin |
In short: choose C E Ferulic if your skin runs normal to dry and lines are the priority. Choose Phloretin CF if your skin runs oily or combination and uneven tone is the priority. Choose Silymarin CF if your skin is oily and blemish-prone.
C E Ferulic vs Resveratrol B E
This one is not an either-or. C E Ferulic is a morning serum and Resveratrol B E is its night-time counterpart. They are formulated for opposite ends of the day and are designed to be used together.
| Serum | When | Main concern | Skin types |
|---|---|---|---|
| C E Ferulic | Morning | Visibly reduces wrinkles and uneven skin tone | Normal, dry, combination, sensitive |
| Resveratrol B E | Night | Visibly firms and brightens skin | Normal, dry, combination, sensitive |
How to use it
- In the morning, after cleansing, dispense four to five drops into clean hands.
- Gently press into the skin on the face, neck and décolletage.
- Follow with the rest of your skincare, and finish with sunscreen.
Three things the carton tells you. Store it in a cool, dark place. L-ascorbic acid will oxidise and darken over time, but it remains effective. A slight tingling on application is normal. For external use only, and avoid direct contact with the eyes.
Where it sits in a routine
SkinCeuticals structures routines around three stages: prevent, correct, protect. C E Ferulic is the prevent step, so it goes on first, before anything corrective.
| Step | Stage | Product |
|---|---|---|
| Step 1 | Prevent | C E Ferulic |
| Step 2 | Correct | P-TIOX wrinkle-modulating peptide serum |
| Step 3 | Correct | A.G.E. Interrupter Advanced |
| Step 4 | Protect | Physical Fusion UV Defense SPF 50 |
You do not need all four to start. C E Ferulic plus a broad-spectrum sunscreen is a complete morning routine on its own; the corrective steps are what you add as your routine matures.
Use around lasers and in-clinic treatments
C E Ferulic has been physician-tested on seven different laser treatments, and tested with lasers across all skin tones. That testing is one reason it appears so often on post-procedure protocols.
Timing after a procedure is a decision for the clinician who treated you. Follow their protocol rather than a general guideline.

What is different about the new C E Ferulic formula?
The 2026 release is a patent-pending formula, marked with a "Patent Pending Formula" flash on the carton and a gold seal in SkinCeuticals' imagery for the product. The active concentrations are unchanged: 15% L-ascorbic acid, 1% alpha tocopherol and 0.5% ferulic acid. How you use it does not change.
Is C E Ferulic used in the morning or at night?
Morning. Apply four to five drops to clean, dry skin once daily after cleansing, then follow with the rest of your routine and sunscreen. Its night-time counterpart in the SkinCeuticals range is Resveratrol B E.
How many drops of C E Ferulic should I use?
Four to five drops, dispensed into clean hands and gently pressed into the face, neck and décolletage.
Can C E Ferulic be used every day?
Yes. The directions call for once-daily use in the morning, after cleansing and before the rest of your routine.
Does C E Ferulic replace sunscreen?
No. C E Ferulic goes on first and sunscreen goes on last. The SkinCeuticals directions specifically call for finishing the routine with a sunscreen.
Why has my C E Ferulic turned darker?
L-ascorbic acid oxidises and darkens over time. According to the SkinCeuticals carton, the serum remains effective as this happens. Storing the bottle in a cool, dark place slows it down.
Is tingling normal with C E Ferulic?
Yes. The carton notes that the formula may cause a slight tingling sensation on application.
C E Ferulic or Phloretin CF — which should I choose?
C E Ferulic is formulated for normal, dry, combination and sensitive skin, with wrinkles and firmness as the focus. Phloretin CF is formulated for normal, oily and combination skin, with skin tone as the focus. If your skin is oily and blemish-prone, Silymarin CF is the one built for that.
Can C E Ferulic be used on all skin tones?
Yes. C E Ferulic has been physician-tested on seven different laser treatments and tested with lasers on all skin tones.
Where can I buy authentic SkinCeuticals C E Ferulic in Canada?
