Dermalogica Biolumin-C Serum vs SkinCeuticals CE Ferulic Serum

Vitamin C is by far the most famous vitamin in skincare, and rightfully so. Regular use of vitamin C helps your skin produce collagen, heal wounds, reverse sun damage, brighten your complexion, prevent aging, and improve overall skin tone. Skin care experts recommend that even the simplest of skincare routines should include vitamin C because it also makes your SPF more effective.

For this particular review, we'll be comparing the Dermalogica Biolumin-C Serum vs SkinCeuticals CE Ferulic Serum.


Worth noting upfront is the fact that both serums not only contain Vitamin C, but also contain another goodie in the form of Vitamin E which helps to protect skin cells from damage and reduces inflammation. That's about as far as the similarities between the two go, though (other than their equally high-end price tags).

The SkinCeuticals C E Ferulic Serum contains the most effective form of Vitamin C at the most effective concentration: 15% L-Ascorbic Acid. The Biolumin-C Serum, on the other hand, contains two vitamin C derivatives: Ascorbyl Methylsilanol Pectinate and Aminopropyl Ascorbyl Phosphates. Both are more stable forms of vitamin C, however this also generally implies they are less potent.

The concentration of Vitamin C in the Biolumin-C Serum is 4.7%, however, Dermalogica claims that their combination of derivatives is scientifically proven to deliver three times the amount of Vitamin C as its competitors. This, of course, would technically bring the figure closer to that more desirable 15%.

The ingredients list of the CE Ferulic Serum is about as lean as a serum gets, with only 12 ingredients in the formula. Other than Vitamins C and E, it contains Ferulic Acid (boosts the effects of Vitamin C), Glycerin (improves skin hydration), Tocopherol (powerful antioxidant), and Hyaluronic Acid (improves hydration) - plus a few solvents such as water, and skin conditioners.

Rather contrastingly, the Biolumin-C Serum contains 32 ingredients, nearly triple the length of SkinCeuticals'. Some would argue that this offers additional value for money, especially considering that some of the other ingredients include Lactic Acid (chemical exfoliant), Tocopherol (powerful antioxidant) and Peptides (stimulates collagen synthesis). Others prefer the more minimal approach since you actually get what you wanted (i.e. a Vitamin C serum) without any undesired extras.


It's difficult to say whether the differing types and concentrations of Vitamin C actually make much of a difference when it comes to results. That said, those looking for a dedicated Vitamin C serum will much prefer the SkinCeuticals C E Ferulic Serum due to its minimal, highly-focussed ingredients list.

The Dermalogica Biolumin-C Serum is one that promises more thanks to its more complex catalogue of actives. In particular, it outperforms the CE Ferulic Serum with regards to tackling dark spots and pigmentation thanks to its additional exfoliating perks. Also, because it doesn't contain L-Ascorbic Acid, it can be safely used with nearly any other product, whereas you would have to be more careful when layering the CE Ferulic Serum with other serums.
