What’s the best Skinceuticals Vitamin C serum?

CE Ferulic is the most famous. But did you know that Skinceuticals makes SIX more?! Like, why do you need that many?!

Anyway… Most of them cost less than CE Ferulic. Should you make the switch? I’ve compared them all to find out who the winner is.

But first…

Why Should You Use Vitamin C?

Vitamin C is an antiaging superstar. This powerful antioxidant fights premature aging in 3 ways:

  • Antioxidant: It destroys free radicals before they can give you wrinkles and dark spots
  • Firming: It boosts collagen, the protein that keeps skin firm and elastic
  • Brightening: It fades away dark spots and makes the complexion glow

Just a warning: L-Ascorbic Acid, the pure form of vitamin C, does these jobs well BUT it can be irritating. If you’ve got sensitive skin, stick to low doses (or go with a derivative).

Skinceuticals CE Ferulic ($166.00)

What form of Vitamin C does it use?: 15% L-Ascorbic acid (the pure form of vitamin C).

What else is here?: This was the original CEF serum. 15% vitamin C, 1% vitamin E and 0.5% ferulic acid. These antioxidants work together to make one another more effective and destroy more free radicals. Plus, they boost the protection of your sunscreen, too.

What’s it good for?: Preventing the premature signs of aging (think wrinkles) and fading away dark spots.

What’s the texture like?: Lightweight, slightly tacky (it smells, too!).

Who should use it?: Most suitable for dry skin types, but anyone who wants to prevent premature aging can use it (unless your skin is too sensitive to tolerate this much vitamin C).

When do you use it?: In the morning, after cleanser and before sunscreen.

Skinceuticals Phloretin CF ($166.00)

What form of Vitamin C does it use?: 10% L-Ascorbic Acid (the pure form of Vitamin C).

What else is here?: 2% phloretin and 0.5% ferulic acid. Phloretin is an antioxidant found in apples that boosts the effectiveness of vitamin C and helps protect skin from UV rays. One study shows that vitamin C + phloretin + ferulic acid + vitamin C (CPF) works just like vitamin C + vitamin E + ferulic acid (CEF). BUT, CEF is the most studied combo of the two, so it has way more proof to back up its effectiveness.

What’s it good for?: Preventing the premature signs of aging, including wrinkles and dark spots.

What’s the texture like?: Lightweight, absorbs quickly.

Who should use it?: Combo and oily skin types who want to prevent premature aging.

What’s The Best Skinceuticals Vitamin C Serum?

Skinceuticals CE Ferulic wins hands down. It has the most effective antioxidant combo to fight premature aging and keep wrinkles away from your face for longer. If your skin is sensitive and can’t tolerate it, go with Serum 10+ AOX+. I’d give the other serums a go only if you can’t stand the texture/smell of CEF Ferulic.
