If you've been researching SkinCeuticals vitamin C serums, you've probably come across two of the brand's most popular antioxidants: C E Ferulic and Phloretin CF.

Both are formulated with pure L-ascorbic acid (vitamin C) and are backed by SkinCeuticals' renowned antioxidant research. They help defend against environmental damage, support collagen production and improve the visible signs of ageing - but they're designed for different skin types and concerns.

So, which one is right for you?

In this guide, we'll compare the ingredients, benefits and ideal skin types for each serum, helping you choose the best antioxidant for your skincare routine.

Vitamin C is one of the most clinically proven skincare ingredients available.

Applied daily, it helps:

• Protect against free radical damage caused by UV exposure and pollution.
• Support natural collagen production.
• Brighten dull skin.
• Improve uneven skin tone.
• Reduce the appearance of fine lines.
• Enhance the effectiveness of your daily sunscreen.

For these reasons, dermatologists and aesthetic practitioners often recommend a vitamin C serum as the cornerstone and foundation of a morning skincare routine - with SPF of course!

C E Ferulic combines:

• 15% pure L-ascorbic acid
• 1% vitamin E
• 0.5% ferulic acid

This iconic formula is designed to protect against oxidative stress while improving firmness, brightness and visible signs of ageing.

The addition of vitamin E provides extra nourishment, making it particularly suitable for people with normal, dry or mature skin. SkinCeuticals C E Ferulic is widely seen as the gold standard in Vitamin C. 

Editor's Pick: SkinCeuticals C E Ferulic

If your primary concerns are fine lines, loss of firmness and maintaining healthy collagen, SkinCeuticals C E Ferulic remains our top recommendation. Its clinically proven combination of vitamin C, vitamin E and ferulic acid provides advanced antioxidant protection while helping to brighten the complexion and support smoother, firmer-looking skin. It's the ideal choice for those looking to prevent and correct the visible signs of skin ageing.

Phloretin CF contains:

• 10% pure L-ascorbic acid
• 2% phloretin
• 0.5% ferulic acid

Instead of vitamin E, this formula incorporates phloretin, a plant-derived antioxidant known for helping improve uneven skin tone while supporting healthy cell turnover.

Its lightweight texture makes it an excellent choice for people with combination, oily or blemish-prone skin. Amazing how Vitamin C can be formulated to suit certain skin types!

Editor's Pick: SkinCeuticals Phloretin CF

If your skin is combination, oily or prone to pigmentation, SkinCeuticals Phloretin CF is an excellent choice. Its lightweight antioxidant formula helps defend against environmental damage while improving skin clarity, refining uneven tone and promoting a brighter complexion without feeling heavy on the skin.

Vitamin C

Both serums contain pure L-ascorbic acid - the gold standard form of topical vitamin C.

Vitamin C helps:

• Protect collagen from oxidative damage.
• Brighten the complexion.
• Improve skin firmness.
• Reduce the appearance of fine lines.

The difference lies in the supporting ingredients.

Vitamin E vs Phloretin

C E Ferulic

Vitamin E provides additional antioxidant protection while helping reinforce the skin barrier and improve hydration.

This makes C E Ferulic particularly beneficial for:

• Dry skin
• Mature skin
• Skin showing visible signs of ageing

Phloretin CF

Phloretin is a botanical antioxidant that supports a more even skin tone and helps reduce oxidative stress.

It is often preferred for:

• Oily skin
• Combination skin
• Acne/Blemish-prone skin
• Pigmentation concerns

Choose C E Ferulic if you have:

- Dry skin

- Normal skin

- Mature skin

- Fine lines and wrinkles

- Loss of firmness/ ageing concerns

- Dehydration

- Combination skin

-  Oily skin

-  Enlarged pores/ blackheads 

- Post-inflammatory pigmentation

-  Uneven skin tone

-  Blemishes

Yes, of course!

Vitamin C and retinoids complement one another beautifully when used at different times of the day.

A simple routine would be:

Morning

• Gentle cleanser
• C E Ferulic or Phloretin CF
• Moisturiser
• SPF 50

Evening

• Cleanser
• Medik8 Crystal Retinal®
• Moisturiser

This combination protects your skin during the day while encouraging natural skin renewal overnight - remember SPF is necessary, as certain products make your skin more sensitive to the sun. 

 Editor's Pick: Medik8 Crystal Retinal®

Retinal remains one of the most effective ingredients for improving fine lines, skin texture and collagen production. Used in the evening alongside a morning antioxidant serum, Medik8 Crystal Retinal® creates a powerful, science-led anti-ageing routine.

Both serums represent a premium investment, but they are also among the most extensively researched antioxidant formulations available.

Rather than simply brightening the skin, they help protect against the environmental damage that contributes to premature ageing while supporting healthier skin over time.

The best choice depends less on price and more on selecting the formulation that best matches your skin type.

FAQ's

Which SkinCeuticals vitamin C serum is best?

Neither serum is universally 'better' - they're designed for different skin types. C E Ferulic is generally best for normal, dry and mature skin, while Phloretin CF is often recommended for combination, oily and blemish-prone skin.

Can I use C E Ferulic if I have oily skin?

Yes, although many people with oily skin prefer the lighter texture of Phloretin CF - or perhaps even Silymarin CF.

Is Phloretin CF good for pigmentation?

Yes. Its antioxidant blend and lightweight formulation make it particularly suitable for improving uneven skin tone and post-inflammatory pigmentation (PIH).

Do I still need sunscreen?

Absolutely. Vitamin C complements sunscreen but does not replace it. Daily broad-spectrum SPF remains essential for protecting your skin against UV damage. Again, we stock a range of sunscreens from different brands, suitable for a range of different skin types. 

Both SkinCeuticals C E Ferulic and Phloretin CF are exceptional antioxidant serums backed by decades of scientific research, but the right choice depends on your skin's individual needs.

If your concerns centre around fine lines, collagen support, dryness and maintaining skin firmness, C E Ferulic is the standout option. Its combination of vitamin C, vitamin E and ferulic acid provides comprehensive antioxidant protection while nourishing the skin and supporting a more youthful-looking complexion.

If your skin is oilier, prone to breakouts or affected by pigmentation, Phloretin CF offers a lighter alternative that helps improve skin clarity and evenness without compromising on antioxidant defence.

Whichever you choose, pairing your vitamin C serum with a broad-spectrum SPF every morning and a retinoid in the evening will help you get the most from your skincare routine and support healthier, more resilient skin in the long term - protected from environmental stressors.
